Description

TECHNIQUES FOR RADIO ACCESS TECHNOLOGY CONCURRENCE FOR PREMISES EQUIPMENT

FIELD OF TECHNOLOGY

The following relates to wireless communications, including techniques for radio access technology concurrence for premises equipment.

BACKGROUND

Wireless communications systems are widely deployed to provide various types of communication content such as voice, video, packet data, messaging, broadcast, and so on. These systems may be capable of supporting communication with multiple users by sharing the available system resources (e.g., time, frequency, and power) . Examples of such multiple-access systems include fourth generation (4G) systems such as Long Term Evolution (LTE) systems, LTE-Advanced (LTE-A) systems, or LTE-A Pro systems, and fifth generation (5G) systems which may be referred to as New Radio (NR) systems. These systems may employ technologies such as code division multiple access (CDMA) , time division multiple access (TDMA) , frequency division multiple access (FDMA) , orthogonal frequency division multiple access (OFDMA) , or discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-S-OFDM) . A wireless multiple-access communications system may include one or more base stations or one or more network access nodes, each simultaneously supporting communication for multiple communication devices, which may be otherwise known as user equipment (UE) .

Premises devices configured to provide fixed wireless access to an area or premises and may support backhaul communication links with a base station in addition to communication links with UEs.

SUMMARY

The described techniques relate to improved methods, systems, devices, and apparatuses that support techniques for radio access technology (RAT) concurrence for premises equipment. Generally, the described techniques provide for interference avoidance between a backhaul communication link and communication links with a user equipment (UE) or multiple UEs in the context of Fixed Wireless Access (FWA) at a premises equipment. In particular, a premises equipment (e.g., Customer Premise Equipment (CPE) ) may be configured to determine whether there is a possibility of interference between a backhaul communication link (e.g., 5G communication link) with a base station and communication links (e.g., Wi-Fi communication links) with one or more UEs. In cases where the premises equipment identifies the possibility of interference, the premises equipment may perform a channel avoidance procedure to select a channel for Wi-Fi communications. In some aspects, the channel avoidance procedure may include applying operation settings to one or more radios to avoid channels which are more susceptible to interference in order to decrease a probability that the channels will be selected for Wi-Fi communications with the UEs.

DETAILED DESCRIPTION

Deploying wireline broadband networks may use high capital expenditure and mid to long term investment. In particular, few hundred meters of last mile deployment can be an obstacle for wireline broadband technologies. A solution to last mile deployment is Fixed Wireless Access (FWA) . FWA (e.g., Fifth Generation (5G) FWA) in the wireless spectrum can be used to quickly and cheaply deliver an alternative to wired broadband. In the millimeter wavelengths, 5G FWA can provide a level of service bandwidth capacity comparable to fiber optics. A Customer Premise Equipment (CPE) device may be configured to provide FWA to a premises. A CPE may include a wireless backhaul unit that establishes a backhaul communication link (e.g., 5G communication link) with broadband network (e.g., 5G network) , and a wireless network unit (e.g., a Wi-Fi router) that establishes communication links with UEs within a premises. Two example implementations of CPEs include: (1) an implementation with an external backhaul antenna, and (2) an implementation where both the backhaul antenna and the network antenna are included within a single CPE device. In the second implementation, if the frequency bands used for the backhaul communication link and the wireless network are close enough together, they may interfere with each other and thereby reduce performance. In this regard, communications associated with the backhaul communication link may interfere with communications associated with the communication link with the UEs. Left unmanaged, such interference may lead to unreliable FWA for the premises.

To address interference issues in the context of premises equipment configured for FWA, the described techniques provide for interference avoidance between a backhaul communication link and communication links with user equipments UEs. In particular, a premises equipment (e.g., CPE) may be configured to determine whether there is a possibility of interference between a backhaul communication link (e.g., 5G communication link) with a base station and communication links (e.g., Wi-Fi communication links) with one or more UEs. In cases where the premises equipment identifies the possibility of interference, the premises equipment may perform a channel avoidance procedure to select a channel for Wi-Fi communications. In some aspects, the channel avoidance procedure may include applying channel avoidance parameters to one or more channels that are more susceptible to interference in order to decrease a probability that the channels will be selected for Wi-Fi communications with the UEs. For example, the premises equipment may apply channel avoidance parameters to one or more subbands, channels, or both, where the channel avoidance parameters reduce the likelihood that the respective subbands, channels, or both, are selected for Wi-Fi communications.

Aspects of the disclosure are initially described in the context of wireless communications systems. Additional aspects of the disclosure are additionally described in the context of an example resource allocation and an example process flow. Aspects of the disclosure are further illustrated by and described with reference to apparatus diagrams, system diagrams, and flowcharts that relate to techniques for radio access technology (RAT) concurrence for premises equipment.

FIG. 1 illustrates an example of a wireless communications system 100 that supports techniques for RAT concurrence for premises equipment in accordance with aspects of the present disclosure. The wireless communications system 100 may include one or more base stations 105, one or more UEs 115, and a core network 130. In some examples, the wireless communications system 100 may be a Long Term Evolution (LTE) network, an LTE-Advanced (LTE-A) network, an LTE-A Pro network, or a New Radio (NR) network. In some examples, the wireless communications system 100 may support enhanced broadband communications, ultra-reliable (e.g., mission critical) communications, low latency communications, communications with low-cost and low-complexity devices, or any combination thereof.

The base stations 105 may be dispersed throughout a geographic area to form the wireless communications system 100 and may be devices in different forms or having different capabilities. The base stations 105 and the UEs 115 may wirelessly communicate via one or more communication links 125. Each base station 105 may provide a coverage area 110 over which the UEs 115 and the base station 105 may establish one or more communication links 125. The coverage area 110 may be an example of a geographic area over which a base station 105 and a UE 115 may support the communication of signals according to one or more radio access technologies.

The UEs 115 may be dispersed throughout a coverage area 110 of the wireless communications system 100, and each UE 115 may be stationary, or mobile, or both at different times. The UEs 115 may be devices in different forms or having different capabilities. Some example UEs 115 are illustrated in FIG. 1. The UEs 115 described herein may be able to communicate with various types of devices, such as other UEs 115, the base stations 105, or network equipment (e.g., core network nodes, relay devices, integrated access and backhaul (IAB) nodes, or other network equipment) , as shown in FIG. 1.

The base stations 105 may communicate with the core network 130, or with one another, or both. For example, the base stations 105 may interface with the core network 130 through one or more backhaul links 120 (e.g., via an S1, N2, N3, or other interface) . The base stations 105 may communicate with one another over the backhaul links 120 (e.g., via an X2, Xn, or other interface) either directly (e.g., directly between base stations 105) , or indirectly (e.g., via core network 130) , or both. In some examples, the backhaul links 120 may be or include one or more wireless links.

One or more of the base stations 105 described herein may include or may be referred to by a person having ordinary skill in the art as a base transceiver station, a radio base station, an access point, a radio transceiver, a NodeB, an eNodeB (eNB) , a next-generation NodeB or a giga-NodeB (either of which may be referred to as a gNB) , a Home NodeB, a Home eNodeB, or other suitable terminology.

A UE 115 may include or may be referred to as a mobile device, a wireless device, a remote device, a handheld device, or a subscriber device, or some other suitable terminology, where the “device” may also be referred to as a unit, a station, a terminal, or a client, among other examples. A UE 115 may also include or may be referred to as a personal electronic device such as a cellular phone, a personal digital assistant (PDA) , a tablet computer, a laptop computer, or a personal computer. In some examples, a UE 115 may include or be referred to as a wireless local loop (WLL) station, an Internet of Things (IoT) device, an Internet of Everything (IoE) device, or a machine type communications (MTC) device, among other examples, which may be implemented in various objects such as appliances, or vehicles, meters, among other examples.

The UEs 115 described herein may be able to communicate with various types of devices, such as other UEs 115 that may sometimes act as relays as well as the base stations 105 and the network equipment including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations, among other examples, as shown in FIG. 1.

The UEs 115 and the base stations 105 may wirelessly communicate with one another via one or more communication links 125 over one or more carriers. The term “carrier” may refer to a set of radio frequency spectrum resources having a defined physical layer structure for supporting the communication links 125. For example, a carrier used for a communication link 125 may include a portion of a radio frequency spectrum band (e.g., a bandwidth part (BWP) ) that is operated according to one or more physical layer channels for a given RAT (e.g., LTE, LTE-A, LTE-A Pro, NR) . Each physical layer channel may carry acquisition signaling (e.g., synchronization signals, system information) , control signaling that coordinates operation for the carrier, user data, or other signaling. The wireless communications system 100 may support communication with a UE 115 using carrier aggregation or multi-carrier operation. A UE 115 may be configured with multiple downlink component carriers and one or more uplink component carriers according to a carrier aggregation configuration. Carrier aggregation may be used with both frequency division duplexing (FDD) and time division duplexing (TDD) component carriers.

In some examples (e.g., in a carrier aggregation configuration) , a carrier may also have acquisition signaling or control signaling that coordinates operations for other carriers. A carrier may be associated with a frequency channel (e.g., an evolved universal mobile telecommunication system terrestrial radio access (E-UTRA) absolute radio frequency channel number (EARFCN) ) and may be positioned according to a channel raster for discovery by the UEs 115. A carrier may be operated in a standalone mode where initial acquisition and connection may be conducted by the UEs 115 via the carrier, or the carrier may be operated in a non-standalone mode where a connection is anchored using a different carrier (e.g., of the same or a different RAT) .

The communication links 125 shown in the wireless communications system 100 may include uplink transmissions from a UE 115 to a base station 105, or downlink transmissions from a base station 105 to a UE 115. Carriers may carry downlink or uplink communications (e.g., in an FDD mode) or may be configured to carry downlink and uplink communications (e.g., in a TDD mode) .

A carrier may be associated with a particular bandwidth of the radio frequency spectrum, and in some examples the carrier bandwidth may be referred to as a “system bandwidth” of the carrier or the wireless communications system 100. For example, the carrier bandwidth may be one of a number of determined bandwidths for carriers of a particular RAT (e.g., 1.4, 3, 5, 10, 15, 20, 40, or 80 megahertz (MHz) ) . Devices of the wireless communications system 100 (e.g., the base stations 105, the UEs 115, or both) may have hardware configurations that support communications over a particular carrier bandwidth or may be configurable to support communications over one of a set of carrier bandwidths. In some examples, the wireless communications system 100 may include base stations 105 or UEs 115 that support simultaneous communications via carriers associated with multiple carrier bandwidths. In some examples, each served UE 115 may be configured for operating over portions (e.g., a sub-band, a BWP) or all of a carrier bandwidth.

Signal waveforms transmitted over a carrier may be made up of multiple subcarriers (e.g., using multi-carrier modulation (MCM) techniques such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform spread OFDM (DFT-S-OFDM) ) . In a system employing MCM techniques, a resource element may consist of one symbol period (e.g., a duration of one modulation symbol) and one subcarrier, where the symbol period and subcarrier spacing are inversely related. The number of bits carried by each resource element may depend on the modulation scheme (e.g., the order of the modulation scheme, the coding rate of the modulation scheme, or both) . Thus, the more resource elements that a UE 115 receives and the higher the order of the modulation scheme, the higher the data rate may be for the UE 115. A wireless communications resource may refer to a combination of a radio frequency spectrum resource, a time resource, and a spatial resource (e.g., spatial layers or beams) , and the use of multiple spatial layers may further increase the data rate or data integrity for communications with a UE 115.

The time intervals for the base stations 105 or the UEs 115 may be expressed in multiples of a basic time unit which may, for example, refer to a sampling period of T _s= 1/ (Δf _max·N _f) seconds, where Δf _max may represent the maximum supported subcarrier spacing, and N _f may represent the maximum supported discrete Fourier transform (DFT) size. Time intervals of a communications resource may be organized according to radio frames each having a specified duration (e.g., 10 milliseconds (ms) ) . Each radio frame may be identified by a system frame number (SFN) (e.g., ranging from 0 to 1023) .

Each frame may include multiple consecutively numbered subframes or slots, and each subframe or slot may have the same duration. In some examples, a frame may be divided (e.g., in the time domain) into subframes, and each subframe may be further divided into a number of slots. Alternatively, each frame may include a variable number of slots, and the number of slots may depend on subcarrier spacing. Each slot may include a number of symbol periods (e.g., depending on the length of the cyclic prefix prepended to each symbol period) . In some wireless communications systems 100, a slot may further be divided into multiple mini-slots containing one or more symbols. Excluding the cyclic prefix, each symbol period may contain one or more (e.g., N _f) sampling periods. The duration of a symbol period may depend on the subcarrier spacing or frequency band of operation.

A subframe, a slot, a mini-slot, or a symbol may be the smallest scheduling unit (e.g., in the time domain) of the wireless communications system 100 and may be referred to as a transmission time interval (TTI) . In some examples, the TTI duration (e.g., the number of symbol periods in a TTI) may be variable. Additionally or alternatively, the smallest scheduling unit of the wireless communications system 100 may be dynamically selected (e.g., in bursts of shortened TTIs (sTTIs) ) .

Physical channels may be multiplexed on a carrier according to various techniques. A physical control channel and a physical data channel may be multiplexed on a downlink carrier, for example, using one or more of time division multiplexing (TDM) techniques, frequency division multiplexing (FDM) techniques, or hybrid TDM-FDM techniques. A control region (e.g., a control resource set (CORESET) ) for a physical control channel may be defined by a number of symbol periods and may extend across the system bandwidth or a subset of the system bandwidth of the carrier. One or more control regions (e.g., CORESETs) may be configured for a set of the UEs 115. For example, one or more of the UEs 115 may monitor or search control regions for control information according to one or more search space sets, and each search space set may include one or multiple control channel candidates in one or more aggregation levels arranged in a cascaded manner. An aggregation level for a control channel candidate may refer to a number of control channel resources (e.g., control channel elements (CCEs) ) associated with encoded information for a control information format having a given payload size. Search space sets may include common search space sets configured for sending control information to multiple UEs 115 and UE-specific search space sets for sending control information to a specific UE 115.

In some examples, a base station 105 may be movable and therefore provide communication coverage for a moving geographic coverage area 110. In some examples, different geographic coverage areas 110 associated with different technologies may overlap, but the different geographic coverage areas 110 may be supported by the same base station 105. In other examples, the overlapping geographic coverage areas 110 associated with different technologies may be supported by different base stations 105. The wireless communications system 100 may include, for example, a heterogeneous network in which different types of the base stations 105 provide coverage for various geographic coverage areas 110 using the same or different radio access technologies.

The wireless communications system 100 may be configured to support ultra-reliable communications or low-latency communications, or various combinations thereof. For example, the wireless communications system 100 may be configured to support ultra-reliable low-latency communications (URLLC) or mission critical communications. The UEs 115 may be designed to support ultra-reliable, low-latency, or critical functions (e.g., mission critical functions) . Ultra-reliable communications may include private communication or group communication and may be supported by one or more mission critical services such as mission critical push-to-talk (MCPTT) , mission critical video (MCVideo) , or mission critical data (MCData) . Support for mission critical functions may include prioritization of services, and mission critical services may be used for public safety or general commercial applications. The terms ultra-reliable, low-latency, mission critical, and ultra-reliable low-latency may be used interchangeably herein.

In some examples, a UE 115 may also be able to communicate directly with other UEs 115 over a device-to-device (D2D) communication link 135 (e.g., using a peer-to-peer (P2P) or D2D protocol) . One or more UEs 115 utilizing D2D communications may be within the geographic coverage area 110 of a base station 105. Other UEs 115 in such a group may be outside the geographic coverage area 110 of a base station 105 or be otherwise unable to receive transmissions from a base station 105. In some examples, groups of the UEs 115 communicating via D2D communications may utilize a one-to-many (1: M) system in which each UE 115 transmits to every other UE 115 in the group. In some examples, a base station 105 facilitates the scheduling of resources for D2D communications. In other cases, D2D communications are carried out between the UEs 115 without the involvement of a base station 105.

The core network 130 may provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. The core network 130 may be an evolved packet core (EPC) or 5G core (5GC) , which may include at least one control plane entity that manages access and mobility (e.g., a mobility management entity (MME) , an access and mobility management function (AMF) ) and at least one user plane entity that routes packets or interconnects to external networks (e.g., a serving gateway (S-GW) , a Packet Data Network (PDN) gateway (P-GW) , or a user plane function (UPF) ) . The control plane entity may manage non-access stratum (NAS) functions such as mobility, authentication, and bearer management for the UEs 115 served by the base stations 105 associated with the core network 130. User IP packets may be transferred through the user plane entity, which may provide IP address allocation as well as other functions. The user plane entity may be connected to the network operators IP services 150. The operators IP services 150 may include access to the Internet, Intranet (s) , an IP Multimedia Subsystem (IMS) , or a Packet-Switched Streaming Service.

Some of the network devices, such as a base station 105, may include subcomponents such as an access network entity 140, which may be an example of an access node controller (ANC) . Each access network entity 140 may communicate with the UEs 115 through one or more other access network transmission entities 145, which may be referred to as radio heads, smart radio heads, or transmission/reception points (TRPs) . Each access network transmission entity 145 may include one or more antenna panels. In some configurations, various functions of each access network entity 140 or base station 105 may be distributed across various network devices (e.g., radio heads and ANCs) or consolidated into a single network device (e.g., a base station 105) .

The wireless communications system 100 may operate using one or more frequency bands, typically in the range of 300 megahertz (MHz) to 300 gigahertz (GHz) . Generally, the region from 300 MHz to 3 GHz is known as the ultra-high frequency (UHF) region or decimeter band because the wavelengths range from approximately one decimeter to one meter in length. The UHF waves may be blocked or redirected by buildings and environmental features, but the waves may penetrate structures sufficiently for a macro cell to provide service to the UEs 115 located indoors. The transmission of UHF waves may be associated with smaller antennas and shorter ranges (e.g., less than 100 kilometers) compared to transmission using the smaller frequencies and longer waves of the high frequency (HF) or very high frequency (VHF) portion of the spectrum below 300 MHz.

The wireless communications system 100 may utilize both licensed and unlicensed radio frequency spectrum bands. For example, the wireless communications system 100 may employ License Assisted Access (LAA) , LTE-Unlicensed (LTE-U) RAT, or NR technology in an unlicensed band such as the 5 GHz industrial, scientific, and medical (ISM) band. When operating in unlicensed radio frequency spectrum bands, devices such as the base stations 105 and the UEs 115 may employ carrier sensing for collision detection and avoidance. In some examples, operations in unlicensed bands may be based on a carrier aggregation configuration in conjunction with component carriers operating in a licensed band (e.g., LAA) . Operations in unlicensed spectrum may include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, among other examples.

A base station 105 or a UE 115 may be equipped with multiple antennas, which may be used to employ techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communications, or beamforming. The antennas of a base station 105 or a UE 115 may be located within one or more antenna arrays or antenna panels, which may support MIMO operations or transmit or receive beamforming. For example, one or more base station antennas or antenna arrays may be co-located at an antenna assembly, such as an antenna tower. In some examples, antennas or antenna arrays associated with a base station 105 may be located in diverse geographic locations. A base station 105 may have an antenna array with a number of rows and columns of antenna ports that the base station 105 may use to support beamforming of communications with a UE 115. Likewise, a UE 115 may have one or more antenna arrays that may support various MIMO or beamforming operations. Additionally or alternatively, an antenna panel may support radio frequency beamforming for a signal transmitted via an antenna port.

The base stations 105 or the UEs 115 may use MIMO communications to exploit multipath signal propagation and increase the spectral efficiency by transmitting or receiving multiple signals via different spatial layers. Such techniques may be referred to as spatial multiplexing. The multiple signals may, for example, be transmitted by the transmitting device via different antennas or different combinations of antennas. Likewise, the multiple signals may be received by the receiving device via different antennas or different combinations of antennas. Each of the multiple signals may be referred to as a separate spatial stream and may carry bits associated with the same data stream (e.g., the same codeword) or different data streams (e.g., different codewords) . Different spatial layers may be associated with different antenna ports used for channel measurement and reporting. MIMO techniques include single-user MIMO (SU-MIMO) , where multiple spatial layers are transmitted to the same receiving device, and multiple-user MIMO (MU-MIMO) , where multiple spatial layers are transmitted to multiple devices.

Beamforming, which may also be referred to as spatial filtering, directional transmission, or directional reception, is a signal processing technique that may be used at a transmitting device or a receiving device (e.g., a base station 105, a UE 115) to shape or steer an antenna beam (e.g., a transmit beam, a receive beam) along a spatial path between the transmitting device and the receiving device. Beamforming may be achieved by combining the signals communicated via antenna elements of an antenna array such that some signals propagating at particular orientations with respect to an antenna array experience constructive interference while others experience destructive interference. The adjustment of signals communicated via the antenna elements may include a transmitting device or a receiving device applying amplitude offsets, phase offsets, or both to signals carried via the antenna elements associated with the device. The adjustments associated with each of the antenna elements may be defined by a beamforming weight set associated with a particular orientation (e.g., with respect to the antenna array of the transmitting device or receiving device, or with respect to some other orientation) .

A base station 105 or a UE 115 may use beam sweeping techniques as part of beam forming operations. For example, a base station 105 may use multiple antennas or antenna arrays (e.g., antenna panels) to conduct beamforming operations for directional communications with a UE 115. Some signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) may be transmitted by a base station 105 multiple times in different directions. For example, the base station 105 may transmit a signal according to different beamforming weight sets associated with different directions of transmission. Transmissions in different beam directions may be used to identify (e.g., by a transmitting device, such as a base station 105, or by a receiving device, such as a UE 115) a beam direction for later transmission or reception by the base station 105.

Some signals, such as data signals associated with a particular receiving device, may be transmitted by a base station 105 in a single beam direction (e.g., a direction associated with the receiving device, such as a UE 115) . In some examples, the beam direction associated with transmissions along a single beam direction may be determined based on a signal that was transmitted in one or more beam directions. For example, a UE 115 may receive one or more of the signals transmitted by the base station 105 in different directions and may report to the base station 105 an indication of the signal that the UE 115 received with a highest signal quality or an otherwise acceptable signal quality.

In some examples, transmissions by a device (e.g., by a base station 105 or a UE 115) may be performed using multiple beam directions, and the device may use a combination of digital precoding or radio frequency beamforming to generate a combined beam for transmission (e.g., from a base station 105 to a UE 115) . The UE 115 may report feedback that indicates precoding weights for one or more beam directions, and the feedback may correspond to a configured number of beams across a system bandwidth or one or more sub-bands. The base station 105 may transmit a reference signal (e.g., a cell-specific reference signal (CRS) , a channel state information reference signal (CSI-RS) ) , which may be precoded or unprecoded. The UE 115 may provide feedback for beam selection, which may be a precoding matrix indicator (PMI) or codebook-based feedback (e.g., a multi-panel type codebook, a linear combination type codebook, a port selection type codebook) . Although these techniques are described with reference to signals transmitted in one or more directions by a base station 105, a UE 115 may employ similar techniques for transmitting signals multiple times in different directions (e.g., for identifying a beam direction for subsequent transmission or reception by the UE 115) or for transmitting a signal in a single direction (e.g., for transmitting data to a receiving device) .

A receiving device (e.g., a UE 115) may try multiple receive configurations (e.g., directional listening) when receiving various signals from the base station 105, such as synchronization signals, reference signals, beam selection signals, or other control signals. For example, a receiving device may try multiple receive directions by receiving via different antenna subarrays, by processing received signals according to different antenna subarrays, by receiving according to different receive beamforming weight sets (e.g., different directional listening weight sets) applied to signals received at multiple antenna elements of an antenna array, or by processing received signals according to different receive beamforming weight sets applied to signals received at multiple antenna elements of an antenna array, any of which may be referred to as “listening” according to different receive configurations or receive directions. In some examples, a receiving device may use a single receive configuration to receive along a single beam direction (e.g., when receiving a data signal) . The single receive configuration may be aligned in a beam direction determined based on listening according to different receive configuration directions (e.g., a beam direction determined to have a highest signal strength, highest signal-to-noise ratio (SNR) , or otherwise acceptable signal quality based on listening according to multiple beam directions) .

The wireless communications system 100 may be a packet-based network that operates according to a layered protocol stack. In the user plane, communications at the bearer or Packet Data Convergence Protocol (PDCP) layer may be IP-based. A Radio Link Control (RLC) layer may perform packet segmentation and reassembly to communicate over logical channels. A Medium Access Control (MAC) layer may perform priority handling and multiplexing of logical channels into transport channels. The MAC layer may also use error detection techniques, error correction techniques, or both to support retransmissions at the MAC layer to improve link efficiency. In the control plane, the Radio Resource Control (RRC) protocol layer may provide establishment, configuration, and maintenance of an RRC connection between a UE 115 and a base station 105 or a core network 130 supporting radio bearers for user plane data. At the physical layer, transport channels may be mapped to physical channels.

The UEs 115 and the base stations 105 may support retransmissions of data to increase the likelihood that data is received successfully. Hybrid automatic repeat request (HARQ) feedback is one technique for increasing the likelihood that data is received correctly over a communication link 125. HARQ may include a combination of error detection (e.g., using a cyclic redundancy check (CRC) ) , forward error correction (FEC) , and retransmission (e.g., automatic repeat request (ARQ) ) . HARQ may improve throughput at the MAC layer in poor radio conditions (e.g., low signal-to-noise conditions) . In some examples, a device may support same-slot HARQ feedback, where the device may provide HARQ feedback in a specific slot for data received in a previous symbol in the slot. In other cases, the device may provide HARQ feedback in a subsequent slot, or according to some other time interval.

The UEs 115, base stations 105, and other wireless communication devices of the wireless communications system 100 may support channel avoidance techniques in the context of FWA. In particular, a premises equipment (e.g., CPE) may be configured to establish communication links with a base station 105 and one or more UEs 115 of the wireless communications system 100 in order to provide FWA. In particular, the premises equipment may be configured to establish a backhaul communication link (e.g., 5G communication link) with the base station 105 of the wireless communications system 100, and may be further configured to establish one or more communication links (e.g., Wi-Fi communication links) with one or more UEs 115 of the wireless communications system 100. In some aspects, the backhaul communication link may operate using a first frequency band (e.g., N79 frequency band) , and the communication links with the UEs 115 may operate using a second frequency band (e.g., wireless local area network (WLAN) 5 GHz band) .

In some aspects, the premises device of the wireless communications system 100 may be configured to determine whether there is a possibility of interference between the backhaul communication link with the base station 105 and the communication links with the UEs 115. For example, the premises equipment may determine that the backhaul communion link operating in the first communication band and the communication links operating in the second communication band operate concurrently, and may thereby identify a possibility of interference between the respective communication links.

In cases where the premises equipment of the wireless communications system 100 identifies the possibility of interference between the backhaul communication link (e.g., 5G communication link) and the communication links (e.g., Wi-Fi communication links) with the UEs 115, the premises equipment may perform a channel avoidance procedure to select a channel for the Wi-Fi communications. In some aspects, the channel avoidance procedure may include applying channel avoidance parameters to one or more subbands and/or channels of the second frequency band associated with the Wi-Fi communications which are more susceptible to interference in order to decrease a probability that the channels will be selected for Wi-Fi communications with the UEs 115. After selecting the channel for communications (e.g., Wi-Fi communications) over the communication links with the UEs 115, the premises equipment may perform concurrent communications with the base station 105 and the UEs 115 over the backhaul communication link and the communication links, respectively.

Techniques described herein may improve the performance and reliability of the premises equipment (e.g., CPE) in the context of FWA. In particular, by performing channel avoidance procedures, techniques described herein may reduce or eliminate potential interference between a backhaul communication link (e.g., 5G link) with the base station 105 and a communication link (e.g., Wi-Fi link, WLAN 5 GHz link) with UEs 115 supported by the premises equipment. In this regard, techniques described herein may enable the premises equipment of the wireless communications system 100 to select efficient channels for Wi-Fi communication which reduce potential interference attributable to 5G communications supported by the premises equipment, thereby providing reliable FWA.

FIG. 2 illustrates an example of a wireless communications system 200 that supports techniques for RAT concurrence for premises equipment in accordance with aspects of the present disclosure. In some examples, wireless communications system 200 may implement aspects of wireless communications system 100. The wireless communications system 200 may include a base station 105-a, a premises equipment 205-a, a first UE 115-a, and a second UE 115-b. In some aspects, the base station 105-a and the UEs 115-a and 115-b may be examples of base stations 105 and UEs 115, as described with reference to FIG. 1. In some aspects, the premises equipment 205-a of the wireless communications system 200 may be configured to provide FWA to a premises 240.

The premises equipment 205-a may communicate with the base station 105-a using a backhaul communication link 210 (e.g., 5G communication link) . In some cases, the backhaul communication link 210 may include an example of an access link (e.g., a Uu link) . The backhaul communication link 210 may include a bi-directional link that can include both uplink and downlink communication. In one aspect, the premises equipment 205-a may transmit uplink transmissions, such as uplink messages or uplink signals, to the base station 105-a using the backhaul communication link 210 and the base station 105-a may transmit downlink transmissions, such as downlink messages or downlink signals, to the premises equipment 205-a using the backhaul communication link 210.

In some aspects, the premises equipment 205-a may establish the backhaul communication link 210 for communications with the base station 105-a using a first RAT (RAT) . For example, the backhaul communication link 210 may include a 5G communication link configured for 5G communications between the premises equipment 205-a and the base station 105-a. In some aspects, the backhaul communication link 210 may operate using a first frequency band. The first frequency band may include a licensed frequency band, such as an N79 frequency band. For example, the first frequency band associated with the backhaul communication link 210 may include a licensed frequency band between 4.4 GHz and 5 GHz.

The premises equipment 205-a may additionally communicate with the first UE 115-a, the second UE 115-b, or both, using a communication link 215 (e.g., Wi-Fi communication link) . The communication link 215 may include a bi-directional link that can include both uplink and downlink communication. In some aspects, the premises equipment 205-a may establish the communication link 215 for communications with the UE 115-a and 115-b using a second RAT. For example, the communication link 215 may include a Wi-Fi communication link configured for Wi-Fi communications between the premises equipment 205-a and the UEs 115. In some aspects, the communication link 215 may operate using a second frequency band that is different from the first frequency band associated with the backhaul communication link 210. In some aspects, the first frequency band and the second frequency band may include adjacent frequency bands, and may be separated via a guard band. The second frequency band may include a WLAN 5 GHz band. In some aspects, the second frequency band associated with the communication link 215 may include an unlicensed frequency band.

In some aspects, the premises equipment 205-a may be configured to provide FWA a premises 240. In this regard, the premises equipment 205-a may be configured to provide FWA to UEs 115 (e.g., first UE 115-a, second UE 115-b) located within the premises 240. The premises 240 may include any premises including, but not limited to, residential premises (e.g., house, apartment, condo) , commercial premises (e.g., building, apartment complex, hotel) , public premises (e.g., parks, malls, schools) , or any combination thereof.

In some aspects, the premises equipment 205-a may include a wireless backhaul unit 220, a wireless network unit 225, a backhaul antenna 235-a, and a network antenna 235-b. The various components of the premises equipment 205-a may be communicatively coupled to one another via wireline or wireless communication links. In some aspects, the premises equipment 205-a may be configured to establish and communicate via the backhaul communication link 210 via the wireless backhaul unit 220 and the backhaul antenna 235-a. In this regard, the wireless backhaul unit 220 may include a modem (e.g., 5G modem) . Similarly, the premises equipment 205-a may be configured to establish and communicate via the communication link 215 via the wireless network unit 225 and the network antenna 235-b. In this regard, the wireless network unit 225 may include a Wi-Fi router.

As shown in FIG. 2, the wireless backhaul unit 220, the wireless network unit 225, the backhaul antenna 235-a, and the network antenna 235-b may be disposed within the same housing. In this regard, the premises equipment 205-a may include a single component (e.g., single unit) that houses the components to provide FWA to a premises. In additional or alternative aspects, the various components of the premises equipment 205-a may be located within two or more housings. For example, in some implementations (not shown) , the wireless backhaul unit 220 and/or the backhaul antenna 235-a may be disposed within a first housing, and the wireless network unit 225 and the network antenna 235-b may be disposed within a second housing. In this example, the components of the first housing and the components of the second housing may be communicatively coupled via a wireline connection. Specifically, the first housing including the wireless backhaul unit 220 and/or the backhaul antenna 235-a may be positioned on an exterior (e.g., outside) of a structure (e.g., building) of the premises 240, and the second housing including the wireless network unit 225 and the network antenna 235-b may be positioned on an interior (e.g., inside) of the structure of the premises.

Splitting the components of the premises equipment 205-a up into two or more housings may provide for increased physical separation between the backhaul antenna 235-aand the network antenna 235-b. Such physical separation may reduce the likelihood of interference between the backhaul communication link 210 and the communication link 215. However, such an implementation may lead to several drawbacks, including increased installation complexity installing the various components/housings of the premises equipment 205-a and increased manufacturing costs.

To address the issues associated with a multi-housing premises equipment, the single-housing premises equipment 205-a illustrated in FIG. 2 may be desirable in that it may reduce installation complexity and manufacturing costs as compared to a multi-housing premises equipment. However, the single-housing premises equipment 205-a may lead to a reduced physical separation between the backhaul antenna 235-a and the network antenna 235-a, thereby increasing the likelihood of interference between the backhaul communication link 210 and the communication link 215. Left unmanaged, such interference may lead to unreliable FWA.

Accordingly, the premises equipment 205-a of the wireless communications system 200 may support channel avoidance techniques between the backhaul communication link 210 and the communication link 215 in order to provide efficient, reliable FWA. While the channel avoidance techniques described herein are primarily shown and described in the context of a single-housing premises equipment 205-a, such techniques may additionally be applied in the context of multi-housing premises equipment 205-a.

In some aspects, the premises equipment 205-a (e.g., CPE) may be configured to determine whether there is a possibility of interference between the backhaul communication link 210 (e.g., 5G communication link) with the base station 105-a and the communication link 215 (e.g., Wi-Fi communication link) with one or more UEs 115 (e.g., first UE 115-a, second UE 115-b) . In cases where the premises equipment 205-a identifies the possibility of interference, the premises equipment 205-a may perform a channel avoidance procedure to select a channel for Wi-Fi communications over the communication link 215. In some aspects, the channel avoidance procedure may include applying channel avoidance parameters to one or more channels which are more susceptible to interference in order to decrease a probability that the channels will be selected for Wi-Fi communications with the UEs 115. For example, the premises equipment 205-a may apply channel avoidance parameters to one or more subbands, channels, or both, where the channel avoidance parameters reduce the likelihood that the respective subbands, channels, or both, are selected for Wi-Fi communications.

Techniques described herein may improve the performance and reliability of the premises equipment 205-a (e.g., CPE) in the context of FWA. In particular, by performing channel avoidance procedures, techniques described herein may reduce or eliminate potential interference between the backhaul communication link 210 (e.g., 5G link) with the base station 105-a and the communication link 215 (e.g., Wi-Fi link, WLAN 5 GHz link) with the UEs 115-a and 115-b supported by the premises equipment 205-a. In this regard, techniques described herein may enable the premises equipment 205-a to select efficient channels for Wi-Fi communication which reduce potential interference attributable to 5G communications supported by the premises equipment 205-a, thereby providing reliable FWA.

FIG. 3 illustrates an example of a resource allocation 300 that supports techniques for RAT concurrence for premises equipment in accordance with aspects of the present disclosure. In some examples, resource allocation 300 may implement, or be implemented by, aspects of

wireless communications systems

100 and 200.

As noted previously herein, a premises equipment 205 (e.g., premises equipment 205-a illustrated in FIG. 2) may provide FWA to one or more UEs 115 by establishing a backhaul communication link with a base station 105 and establishing a communication link with the one or more UEs 115. In some aspects, the premises equipment 205 may establish the backhaul communication link for communications with the base station 105 over the first frequency band 305-a using a first RAT. For example, the backhaul communication link may include a 5G communication link configured for 5G communications between the premises equipment 205-b and the base station 105-b. In some aspects, the first frequency band 305-aassociated with the backhaul communication link may include a licensed frequency band, such as an N79 frequency band. For example, the first frequency band 305-a may include a licensed frequency band between 4.4 GHz and 5 GHz.

The premises equipment 205 may additionally identify that a communication link between the premises equipment 205 and the UE 115 operates using a second frequency band 305-b. In some aspects, the premises equipment 205 may identify that the communication link associated with the second frequency band 305-b is operate concurrently with the backhaul communication link operated using the first frequency band 305-a. In some aspects, the premises equipment 205 may establish the communication link for communications with the UE 115-c associated with the second frequency band 305-b using a second RAT. For example, the communication link may include a Wi-Fi communication link configured for Wi-Fi communications between the premises equipment 205-b and the UE 115-c. In some aspects, the second frequency band 305-b may include a WLAN 5 GHz band. In some aspects, the second frequency band 305-b associated with the communication link with the UE 115-c may include an unlicensed frequency band.

In some aspects, the second frequency band 305-b (e.g., WLAN 5 GHz band) may be separated from the first frequency band 305-a (e.g., N79 band) by a guard band 310. For example, in some cases, the second frequency band 305-b may be separated from the first frequency band 305-a by a frequency between 5 GHz and 5.150 GHz. In some aspects, the second frequency band 305-b may include one or more subbands 315. In some cases, the composition of the second frequency band 305-b may be dependent upon a location of the premises equipment 205. For example, in cases where the premises equipment 205 is located in a first location (e.g., Location 1) , the second frequency band 305-b may include a subband 315-b, a subband 315-c, and a subband 315-d. For instance, composition of the second frequency band 305-b of Location 1 illustrated in FIG. 3 may include an example resource allocation of the second frequency band 305-b in Japan. By way of another example, in cases where the premises equipment 205 is located in a second location (e.g., Location 2) , the second frequency band 305-b may include a subband 315-a, a subband 315-b, a subband 315-c, and a subband 315-d. For instance, composition of the second frequency band 305-b of Location 2 illustrated in FIG. 3 may include an example resource allocation of the second frequency band 305-b in China. Accordingly, in some aspects, the premises equipment 205 may be configured to determine a location of the premises equipment 205 such that the premises equipment 205 may determine a composition of the second frequency band 305-b dependent upon the location.

For example, in cases where the premises equipment 205-b is located in Location 1 (e.g., Japan) , the second frequency band may include an unlicensed frequency band between 5.150 GHz and 5.725 GHz. Furthermore, in cases where the premises equipment 205-b is located in Location 1, the second frequency band 30–5b may include a U-NII-1 subband (e.g., subband 315-d) , a U-NII-2A subband (e.g., subband 315-c) , and a U-NII-2C subband (e.g., subband 315-b) . For instance, in cases where the premises equipment 205-b is located in Location 2, the second frequency band 305-b may include a first frequency subband 315-b between 5.470 GHz and 5.725 GHz (e.g., U-NII-2C subband) , a second frequency subband 315-c between 5.25 GHz and 5.35 GHz (e.g., U-NII-2A subband) , and a third frequency subband 315-d between 5.15 GHz and 5.25 GHz (e.g., U-NII-1 subband) .

By way of another example, in cases where the premises equipment 205 is located in Location 2 (e.g., China) , the second frequency band 305-b may include an unlicensed frequency band between 5.150 GHz and 5.850 GHz. Furthermore, in cases where the premises equipment 205 is located in Location 2, the second frequency band 305-b may include a U-NII-1 subband, a U-NII-2A subband, a U-NII-2C subband, and a U-NII-3 subband. For instance, in cases where the premises equipment 205 is located in Location 2, the second frequency band 305-b may include a first frequency subband 315-a between 5.725 GHz and 5.85 GHz (e.g., U-NII-3 subband) , a second frequency subband 315-b between 5.47 GHz and 5.725 GHz (e.g., U-NII-2C subband) , a third frequency subband 315-c between 5.25 GHz and 5.35 GHz (e.g., U-NII-2A subband) , and a fourth frequency subband 315-dbetween 5.15 GHz and 5.25 GHz (e.g., U-NII-1 subband) .

In some wireless communications systems configured for FWA, there may be an equal probability that each subband 315 which is available (e.g., open) in a given location will be selected for Wi-Fi communications. For example, in Location 1, the probability of selecting the subband 315-d for Wi-Fi communications may be equal to the probabilities of selecting the subbands 315-c and 315-d, respectively. However, due to the closer proximity of the subbands 315-d and 315-c to the N79 band used for the backhaul communication link, the subbands 315-d and 315-c may be more susceptible to interference as compared to the subband 315-b. In this regard, subband 315-b may be the most desirable for Wi-Fi communications in Location 1.

Similarly, subband 315-a may be most desirable for Wi-Fi communications in Location 2. In some cases, subband 315-d may be second most desirable for Wi-Fi communications in Location 2 despite the close proximity to the N79 band. This may be due to various communication parameters of subband 315-d. In this regard, the priority ranking for Wi-Fi communications in Location 2 may be subband 315-a then subband 315-d, followed by subband 315-b and subband 315-b.

In order to reduce potential interference on the communication links (e.g., Wi-Fi communication links) attributable to the backhaul communication link, the premises equipment 205 may be configured to perform channel avoidance procedures.

For example, the premises equipment 205 may identify an operational state of the second frequency band 305-b. Operational states of the second frequency band 305-b may include, but are not limited to, full-band operation, single-band simultaneous (SBS) operation, and the like. For example, in some cases, the premises equipment 205 may identify that the premises equipment 205 communicates with one or more UEs 115 using one channel in the second frequency band 305-b according to a full band operation associated with the second frequency band 305-b. By way of another example, in other cases, the premises equipment 205 may identify that the premises equipment 205 communicates with one or more UEs 115 using two channels (e.g., a first channel and a second channel) in the second frequency band 305-b according to an SBS operation associated with the second frequency band 305-b. In this example, the two channels may be associated with the same subband 315 within the second frequency band 305-b, or in different subbands 315 of the second frequency band 305-b. For instance, the first channel may be associated with (e.g., included within) a first frequency subband 315-a, and the second channel may be associated with (e.g., included within) a second frequency subband 315-b.

The premises equipment 205 may additionally identify a target bandwidth of a channel in the respective subbands 315. In some aspects, the premises equipment 205 may identify the target bandwidth of the channel based on identifying that the premises equipment 205 communicates according to an SBS operation at 425. In some cases, the target bandwidth may include 80 MHz, 40 MHz, or 20 MHz. Additionally or alternatively, the premises equipment 205 may identify a frequency distance (e.g., bandwidth of the guard band 310) between the first frequency band 305-a (e.g., N79 band) and the second frequency band 305-b (e.g., WLAN 5 GHz band) . For example, the premises equipment 205 may identify a frequency distance between a first limit (e.g., upper frequency limit) of the first frequency band 305-a, and a second limit (e.g., lower frequency limit) of the second frequency band 305-b.

In some aspects, the premises equipment 205 may perform a channel avoidance procedure associated with the second frequency band 305-b. In some aspects, the premises equipment 205 may perform the channel access procedure to eliminate or reduce a likelihood of interference or noise associated with communications over the backhaul communication link with the base station 105 and the communication link with the UEs 115. Accordingly, in some aspects, the premises equipment 205 may perform the channel avoidance procedure based on identifying the location of the premises equipment, identifying the backhaul communication link, identifying the communication link with the UEs 115, determining the backhaul communication link and the communication link are operated concurrently, identifying the operational state of the second frequency band 305-b, identifying the target bandwidth, or any combination thereof.

In some aspects, the channel performance procedure may include any algorithms, procedures, or techniques which adjust the likelihood (e.g., probability) that given subbands 315, channels within the respective subband 315, or both, associated with the second frequency band 305-b will be selected for communications with the UE 115 over the communication link. In this regard, the channel avoidance procedure may be used to decrease the probability that subbands 315 and/or channels which are more likely to suffer interference attributable to the backhaul communication link will be selected for communications with the UE 115 over the communication link. Accordingly, by reducing a probability that a given subband 315 and/or channel within a given subband 315 which is more susceptible to interference will be selected for communications over the communication link with the UE 115, the channel avoidance procedure may, in effect, increase a probability that a given subband 315 and/or channel which is less susceptible to interreference will be selected for communications over the communication link with the UE 115.

For example, while performing the channel avoidance procedure in Location 1, the premises equipment 205 may apply channel avoidance parameters to one or more subbands 315 (e.g., subband 315-d, subband 315-c) of the second frequency band 305-b. The premises equipment 205 may apply the channel avoidance parameters based on identifying that the communication link operates using the second frequency band 305-b concurrently with the backhaul communication link operating using the first frequency band 305-a. In this example, the channel avoidance parameters may be configured to reduce the likelihood (e.g., probability) that the frequency subbands 315-d and 315-c will be selected for communications with the UE 115. For instance, the premises equipment 205 may identify that the frequency subbands 315-d and 315-c may be susceptible to interference attributable to the backhaul communication link, and may therefore apply the channel avoidance parameters to the subbands 315-d and 315-c of the second frequency band 305-b to reduce the probability that the subbands 315-d and 315-c will be selected for communications with the UE 115 over the communication link. In effect, the channel avoidance procedure may increase a likelihood (e.g., probability) that the subband 315-b will be selected for communications with the UE 115.

By way of another example, while performing the channel avoidance procedure in Location 2, the premises equipment 205 may apply channel avoidance parameters to one or more subbands 315 (e.g., subband 315-d, subband 315-c, and subband 315-b) of the second frequency band 305-b. In this example, the channel avoidance parameters may be configured to reduce the likelihood (e.g., probability) that the frequency subbands 315-d, 315-c, and 315-b will be selected for communications with the UE 115. For instance, the premises equipment 205 may identify that the frequency subbands 315-d, 315-c, and 315-b may be susceptible to interference attributable to the backhaul communication link, and may therefore apply the channel avoidance parameters to the subbands 315-d, 315-c, and 315-b of the second frequency band 305-b to reduce the probability that the subbands 315-d, 315-c, and 315-b will be selected for communications with the UE 115 over the communication link. In effect, the channel avoidance procedure may increase a likelihood (e.g., probability) that the subband 315-a will be selected for communications with the UE 115.

By way of another example, the premises equipment 205 may identify that the premises equipment 205 communicates with one or more UEs 115 using one channel in the frequency band 305-b according to a full-band operation associated with the second frequency band 305-b. In this example, the premises equipment 205 may apply, as part of the channel avoidance procedure, a channel avoidance parameter to one or more frequency subbands 315 (e.g., U-NII-1 subband, U-NII-2A subband, U-NII-2C subband) of the second frequency band 305-b based on identifying that the premises equipment 205 communicates according to the full-band operation. In this regard, the premises equipment 205 may reduce a probability that the one or more frequency subbands 315 will be selected for the communication link based on identifying the full-band operation. For instance, in cases where the premises equipment 205 is located in Location 1 (e.g., Japan) and determines full-band operation, the premises equipment 205 may apply channel avoidance parameters to the subband 315-d (e.g., U-NII-1 subband) , the subband 315-c (e.g., U-NII-2A subband) , or both, but not to the subband 315-b (e.g., U-NII-2C subband) . Similarly, in cases where the premises equipment 205 is located in Location 2 (e.g., China) and determines full-band operation, the premises equipment 205 may apply channel avoidance parameters to the subband 315-d (e.g., U-NII-1 subband) , the subband 315-c (e.g., U-NII-2A subband) , the subband 315-b (e.g., U-NII-2C subband) , or any combination thereof, but not to the subband 315-a (e.g., U-NII-3 subband) .

By way of another example, the premises equipment 205 may identify that the premises equipment 205 communicates with one or more UEs 115 using two channels in the second frequency band 305-b according to an SBS operation associated with the second frequency band 305-b, where a first channel is in a first frequency subband 315 of the second frequency band 305-b and a second channel is in a second frequency subband 315 of the second frequency band 305-b. In this example, the premises equipment 205 may apply, as part of the channel avoidance procedure, a channel avoidance parameter to a third frequency subband 315 of the second frequency band 305-b based on identifying that the premises equipment 205 communicates according to the SBS operation.

For example, in cases where the premises equipment 205 is located in Location 1 (e.g., Japan) and determines SBS operation in subband 315-d (e.g., U-NII-1 subband) and subband 315-c (e.g., U-NII-2A subband) , the premises equipment 205 may apply channel avoidance parameters to the subband 315-d, but not to the subband 315-c. By way of another example, in cases where the premises equipment 205 is located in Location 2 (e.g., China) and determines SBS operation in subband 315-d (e.g., U-NII-1 subband) and subband 315-c (e.g., U-NII-2A subband) , the premises equipment 205 may apply channel avoidance parameters to the subband 315-d, but not to the subband 315-c. By way of another example, in cases where the premises equipment 205 is located in Location 2 (e.g., China) and determines SBS operation in subband 315-a (e.g., U-NII-3 subband) and subband 315-b (e.g., U-NII-2C subband) , the premises equipment 205 may apply channel avoidance parameters to the subband 315-b, but not to the subband 315-a.

Moreover, the premises equipment 205 may apply one or more channel avoidance parameters based on an identified target bandwidth of a channel in the second frequency band 305-b. For example, the premises equipment 205 may identify SBS operation of the second frequency band 305-b, and may identify a target bandwidth of a channel in the second frequency band 305-b based on the SBS operation. In this example, the premises equipment may apply, as part of the channel avoidance procedure, a channel avoidance parameter to one or more channels of a first frequency band 305-b based on identifying the target bandwidth of the channel.

For instance, in cases where the premises equipment 205 is located in Location 1 (e.g., Japan) , determines SBS operation in subband 315-c (e.g., U-NII-2C subband) , and identifies a target bandwidth of 80 MHz, the premises equipment 205 may apply channel avoidance parameters to Channels 118, 126, 116, 120, 124, and 128 (e.g., smaller channels within Channel 122) within the subband 315-c, but not to the Channel 122 within the subband 315-b (e.g., the highest 80 MHz channel in U-NII-2C) . By way of another example, in cases where the premises equipment 205 is located in Location 1 (e.g., Japan) , determines SBS operation in subband 315-c (e.g., U-NII-2C subband) , and identifies a target bandwidth of 40 MHz, the premises equipment 205 may apply channel avoidance parameters to Channels 132 and 136 (e.g., smaller channels within Channel 134) within the subband 315-c, but not to the Channel 134 within the subband 315-b (e.g., the highest 40 MHz channel in U-NII-2C) . By way of another example, in cases where the premises equipment 205 is located in Location 1 (e.g., Japan) , determines SBS operation in subband 315-c (e.g., U-NII-2C subband) , and identifies a target bandwidth of 20 MHz, the premises equipment 205 may apply channel avoidance parameters to all channels except Channel 140 within the subband 315-b (e.g., the highest 20 MHz channel in U-NII-2C) .

In some aspects, the premises equipment 204 may select a channel in a frequency subband 315 of the second frequency band 305-b for the communication link based on (e.g., using) the channel avoidance procedure. In some aspects, the premises equipment 205 may select the channel in the frequency subband 315 based on identifying the location of the premises equipment 205, identifying the backhaul communication link and/or communication link, identifying the operational state of the second frequency band 305-b, identifying the target bandwidth of the channel, performing the channel avoidance procedure, or any combination thereof. For example, the premises equipment 205 may select the channel in the frequency subband 315 based on identifying that the communication link operates using the second frequency band 305-b concurrently with the backhaul communication link operating using the first frequency band 305-a.

In some aspects, the premises equipment 205 may select the channel in the frequency subband 315 (e.g., first frequency subband 315) of the second frequency band 305-b based on applying one or more channel avoidance parameters to one or more other frequency subbands 315 (e.g., second frequency subband 315, third frequency subband 315) . of the second frequency band 305-b. Moreover, in additional or alternative aspects, the premises equipment 205 may select the channel in the first frequency subband 315 based on applying one or more channel avoidance parameters to one or more other channels in the first frequency subband 315.

In some aspects, the premises equipment 205 may select the channel in the frequency subband 315 of the second frequency band 305-b based on determining a frequency distance between the first frequency band 305-a (e.g., N79 band) and the second frequency band 305-b (e.g., WLAN 5 GHz band) satisfies a threshold. For example, as noted previously herein, the premises equipment 205 may identify a frequency distance (e.g., bandwidth of a guard band 310) between the first frequency band 305-a (e.g., N79 band) and the second frequency band 305-b (e.g., WLAN 5 GHz band) . In this example, the premises equipment 205 may compare the frequency distance to a threshold, and select the channel based on determining that the frequency distance satisfies a threshold. In some cases, the premises equipment 205 may determine that the frequency distance satisfies the threshold when the frequency distance is greater than the threshold.

The premises equipment 205 may communicate with the UE 115 using the selected channel of the frequency subband 315 within the second frequency band 305-b. In some aspects, the premises equipment 205 may communicate with the UE 115 using the selected channel within the second frequency band 305-b based on identifying the location of the premises equipment, identifying the backhaul communication link and/or communication link, identifying the operational state of the second frequency band 305-b, identifying the target bandwidth of the channel, performing the channel avoidance procedure, or any combination thereof.

Additionally, the premises equipment 205 may communicate with the base station 105 using the backhaul communication link in the first frequency band 305-a. In some aspects, the premises equipment 205 may communicate with the base station 105 using the backhaul communication link based on selecting the channel of the second frequency band 305-b. Moreover, the premises equipment 205 may communicate with the base station 105 using the backhaul communication link based on identifying the location of the premises equipment 205, identifying the backhaul communication link and/or communication link, identifying the operational state of the second frequency band 305-b, identifying the target bandwidth of the channel, performing the channel avoidance procedure, or any combination thereof.

In some aspects, the premises equipment 205 may communicate with the UE 115 and the base station 105 concurrently. In this regard, the communications with the UE 115 over the communication link and the communications with the base station 105 over the backhaul communication link may occur concurrently such that the communications at least partially overlap in the time domain. For example, the premises equipment 205 may communicate with the base station 105 using the backhaul communication link in the first frequency band 305-a during a first duration, and may communicate with the UE 115 using the communication link in the second frequency band 305-b during a second duration. In this example, the first duration may at least partially overlap with the second duration such that the communications with the UE 115 and the base station 105 take place concurrently during the duration of the overlap between the first duration and the second duration.

Techniques described herein may improve the performance and reliability of the premises equipment 205 (e.g., CPE) in the context of FWA. In particular, by performing channel avoidance procedures, techniques described herein may reduce or eliminate potential interference between a backhaul communication link (e.g., 5G link) with the base station 105 and a communication link (e.g., Wi-Fi link, WLAN 5 GHz link) with a UE 115 supported by the premises equipment 205. In this regard, techniques described herein may enable the premises equipment 205 to select efficient channels for Wi-Fi communication which reduce potential interference attributable to 5G communications supported by the premises equipment 205, thereby providing reliable FWA.

FIG. 4 illustrates an example of a process flow 400 that supports techniques for RAT concurrence for premises equipment in accordance with aspects of the present disclosure. In some examples, process flow 400 may implement, or be implemented by, aspects of

wireless communications systems

100 and 200, or resource allocation 300. The process flow 400 may illustrate determining a location of a premises equipment, identifying a backhaul communication link associated with a base station and a communication link associated with a UE, performing a channel avoidance procedure, and selecting a channel for communications with the UE based on performing the channel avoidance procedure, as described with reference to FIGs. 1–3, among other aspects.

In some aspects, process flow 400 may include a premises equipment 205-b, a UE 115-c, and a base station 105-b, which may be examples of corresponding devices as described herein. In particular, the premises equipment 205-b illustrated in FIG. 4 may be an example of the premises equipment 205-a illustrated in FIG. 2. Similarly, the UE 115-b and the base station 105-b illustrated in FIG. 4 may be examples of the UE 115-a and 115-b, and the base station 105-a illustrated in FIG. 2, respectively.

In some aspects, the operations illustrated in process flow 400 may be performed by hardware (e.g., including circuitry, processing blocks, logic components, and other components) , code (e.g., software or firmware) executed by a processor, or any combination thereof. Alternative examples of the following may be implemented, where some steps are performed in a different order than described or are not performed at all. In some cases, steps may include additional features not mentioned below, or further steps may be added.

In some aspects, the premises equipment 205-b (e.g., CPE) illustrated in FIG. 4 may be configured to provide FWA to a premises including, but not limited to, residential premises (e.g., house, apartment, condo) , commercial premises (e.g., building, apartment complex, hotel) , public premises (e.g., parks, malls, schools) , or any combination thereof. The premises equipment 205-b may be configured to establish a backhaul communication link (e.g., 5G communication link) for communications with the base station 105-b using a first RAT (e.g., 5G) , and may be configured to establish a communication link (e.g., Wi-Fi communications link) for communications with the UE 115-c using a second RAT (e.g., Wi-Fi) .

At 405, premises equipment 205-b may receive an indication of a location of the premises equipment 205-b from the base station 105-b. In some aspects, the indication of the location may indicate a city, state, region, territory, or country in which the premises equipment 205-b is located. The premises equipment 205-b may additionally or alternatively receive an indication of the location of the premises equipment 205-b from one or more other communication devices. For example, in some cases, the premises equipment 205-b may receive an indication of the location of the premises equipment 205-b from a server. For instance, the premises equipment 205-b may receive an indication of the location of the premises equipment 205-b from a server of the wireless communications system 100 illustrated in FIG. 1. In some examples, a parameter a parameter or software property on the CPE itself may be statically set so that it specifies the location of the CPE. In some examples, ways of reading/retrieving the permitted frequency bands usable in that location could be done statically or via a network/location database query.

At 410, the premises equipment 205-b may identify a location of the premises equipment 205-b. In this regard, the premises equipment 205-b may identify a city, state, region, territory, or country in which the premises equipment 205-b is located. For example, in some cases, the premises equipment 205-b may determine that it is located in China. In other cases, the premises equipment 205-b may determine that it is located in Japan. In some aspects, the premises equipment 205-b may determine the location at 410 based on the indication of the location received from the base station 105-b or other wireless communications device at 405.

At 415, the premises equipment 205-b may identify that a backhaul communication link between the premises equipment 205-b and the base station 105-b operates using a first frequency band. In some aspects, the premises equipment 205-b may identify that the backhaul communication link operates using the first frequency band based on identifying the location of the premises equipment at 410. For example, the premises equipment 205-b may identify that the backhaul communication link (e.g., 5G communication link) operates using an N79 frequency band based on identifying that the premises equipment is located in Japan or China.

In some aspects, the premises equipment 205-b may establish the backhaul communication link for communications with the base station 105-b using a first RAT. For example, the backhaul communication link may include a 5G communication link configured for 5G communications between the premises equipment 205-b and the base station 105-b. In some aspects, the first frequency band associated with the backhaul communication link may include a licensed frequency band. For example, the first frequency band may include a licensed frequency band between 4.4 GHz and 5 GHz.

At 420, the premises equipment 205-b may identify that a communication link between the premises equipment 205-b and the UE 115-c operates using a second frequency band. In some aspects, the premises equipment 205-b may identify that the communication link associated with the second frequency band is operate concurrently with the backhaul communication link. In some aspects, the premises equipment 205-b may identify that the communication link operates using the second frequency band based on identifying that the backhaul communication link operates using the first frequency band at 415, identifying the location of the premises equipment 205-b at 410, or both.

In some aspects, the premises equipment 205-b may establish the communication link for communications with the UE 115-c using a second RAT. For example, the communication link may include a Wi-Fi communication link configured for Wi-Fi communications between the premises equipment 205-b and the UE 115-c. In some aspects, the second frequency band may include a WLAN 5 GHz band. In some aspects, the second frequency band associated with the communication link with the UE 115-c may include an unlicensed frequency band. For example, in cases where the premises equipment 205-b is located in China, the second frequency band may include an unlicensed frequency band between 5.150 GHz and 5.850 GHz. By way of another example, in cases where the premises equipment 205-b is located in Japan, the second frequency band may include an unlicensed frequency band between 5.150 GHz and 5.725 GHz.

In some aspects, the second frequency band (e.g., WLAN 5 GHz band) may be separated from the first frequency band (e.g., N79 band) by a guard band. For example, in some cases, the second frequency band may be separated from the first frequency band by a frequency between 5 GHz and 5.150 GHz. In some aspects, the second frequency band may include one or more subbands. In some cases, the one or more subbands may include one or more U-NII bands. For example, in cases where the premises equipment 205-b is located in Japan, the second frequency band may include a U-NII-a subband, a U-NII-2A subband, and a U-NII-2C subband. For instance, in cases where the premises equipment 205-b is located in Japan, the second frequency band may include a first frequency subband between 5.470 GHz and 5.725 GHz (e.g., U-NII-2C subband) , a second frequency subband between 5.25 GHz and 5.35 GHz (e.g., U-NII-2A subband) , and a third frequency subband between 5.15 GHz and 5.25 GHz (e.g., U-NII-1 subband) .

By way of another example, in cases where the premises equipment 205-b is located in China, the second frequency band may include a U-NII-1 subband, a U-NII-2A subband, a U-NII-2C subband, and a U-NII-3 subband. For instance, in cases where the premises equipment 205-b is located in China, the second frequency band may include a first frequency subband between 5.725 GHz and 5.85 GHz (e.g., U-NII-3 subband) , a second frequency subband between 5.47 GHz and 5.725 GHz (e.g., U-NII-2C subband) , a third frequency subband between 5.25 GHz and 5.35 GHz (e.g., U-NII-2A subband) , and a fourth frequency subband between 5.15 GHz and 5.25 GHz (e.g., U-NII-1 subband) .

At 425, the premises equipment 205-b may identify an operational state of the second frequency band. Operational states of the second frequency band may include, but are not limited to, full-band operation, SBS operation, and the like. For example, in some cases, the premises equipment may identify that the premises equipment 205-b communicates with one or more UEs 115 (e.g., UE 115-c) using one channel in the second frequency band according to a full band operation associated with the second frequency band. By way of another example, in other cases, the premises equipment 205-b may identify that the premises equipment 205-b communicates with one or more UEs 115 (e.g., UE 115-c) using two channels (e.g., a first channel and a second channel) in the second frequency band according to an SBS operation associated with the second frequency band. In this example, the two channels may be associated with the same subband within the second frequency band, or in different subbands of the second frequency band. For instance, the first channel may be associated with (e.g., included within) a first frequency subband, and the second channel may be associated with (e.g., included within) a second frequency subband.

At 430, the premises equipment 205-b may identify a target bandwidth of a channel of the second frequency subband. In some aspects, the premises equipment 205-b may identify the target bandwidth of the channel based on identifying that the premises equipment 205-b communicates according to an SBS operation at 425. In some cases, the target bandwidth may include 80 MHz, 40 MHz, or 20 MHz.

Additionally or alternatively, the premises equipment 205-b may identify a frequency distance (e.g., guard band) between the first frequency band (e.g., N79 band) and the second frequency band (e.g., WLAN 5 GHz band) . For example, the premises equipment 205-b may identify a frequency distance between a first limit (e.g., upper frequency limit) of the first band, and a second limit (e.g., lower frequency limit) of the second frequency band.

At 435, the premises equipment 205-b may perform a channel avoidance procedure associated with the second frequency band. In some aspects, the premises equipment 205-b may perform the channel access procedure to eliminate or reduce a likelihood of interference or noise associated with communications over the backhaul communication link with the base station 105-b and the communication link with the UE 115-c. Accordingly, in some aspects, the premises equipment 205-b may perform the channel avoidance procedure based on identifying the location of the premises equipment at 410, identifying the backhaul communication link at 415, identifying the communication link at 420, determining the backhaul communication link and the communication link are operated concurrently, identifying the operational state of the second frequency band at 425, identifying the target bandwidth at 430, or any combination thereof.

In some aspects, the channel performance procedure may include any algorithms, procedures, or techniques which adjust the likelihood (e.g., probability) that given subbands, channels, or both, associated with the second frequency band will be selected for communications with the UE 115-c over the communication link. In this regard, the channel avoidance procedure may be used to decrease the probability that subbands and/or channels which are more likely to suffer interference attributable to the backhaul communication link will be selected for communications with the UE 115-c over the communication link. Accordingly, by reducing a probability that a given subband and/or channel which is more susceptible to interference will be selected for communications over the communication link with the UE 115-c, the channel avoidance procedure may, in effect, increase a probability that a given subband and/or channel which is less susceptible to interreference will be selected for communications over the communication link with the UE 115-c.

For example, while performing the channel avoidance procedure, the premises equipment 205-b may apply a channel avoidance parameter to a second frequency subband of the second frequency band. The premises equipment 205-b may apply the channel avoidance parameter based on identifying that the communication link operates using the second frequency band concurrently with the backhaul communication link operating using the first frequency band. In this example, the channel avoidance parameter may be configured to reduce the likelihood (e.g., probability) that the second frequency subband will be selected for communications with the UE 115-c. For instance, the premises equipment 205-c may identify that the second frequency subband may be susceptible to interference attributable to the backhaul communication link, and may therefore apply the channel avoidance parameter to the second frequency subband to reduce the probability that the second frequency subband will be selected for communications with the UE 115-c over the communication link.

By way of another example, the premises equipment 205-b may identify (at 425) that the premises equipment 205-b communicates with one or more UEs 115 (e.g., UE 115-c) using one channel in the second frequency band according to a full-band operation associated with the second frequency band. In this example, the premises equipment 205-c may apply, as part of the channel avoidance procedure, a channel avoidance parameter to a second frequency subband (e.g., U-NII-1 subband, U-NII-2A subband, U-NII-2C subband) of the second frequency band based on identifying that the premises equipment 205-b communicates according to the full-band operation. In this regard, the premises equipment 205-b may reduce a probability that the second frequency subband will be selected for the communication link based on identifying the full-band operation.

By way of another example, the premises equipment 205-b may identify (at 425) that the premises equipment 205-b communicates with one or more UEs 115 (e.g., UE 115-c) using two channels in the second frequency band according to an SBS operation associated with the second frequency band, where a first channel is in a first frequency subband (e.g., U-NII-2C subband) of the second frequency band and a second channel is in a second frequency subband (e.g., U-NII-2A) of the second frequency band. In this example, the premises equipment 205-c may apply, as part of the channel avoidance procedure, a channel avoidance parameter to a third frequency subband (e.g., U-NII-1 subband) of the second frequency band based on identifying that the premises equipment 205-b communicates according to the SBS operation. In this regard, the premises equipment 205-b may reduce a probability that the third frequency subband will be selected for the communication link based on identifying the SBS operation in the first and second frequency subbands.

Similarly, the premises equipment 205-b may apply one or more channel avoidance parameters based on an identified target bandwidth of a channel in the second frequency band. For example, the premises equipment 205-b may identify SBS operation of the second frequency band at 435, and may identify a target bandwidth of a channel in the second frequency band at 430 based on the SBS operation. In this example, the premises equipment may apply, as part of the channel avoidance procedure, a channel avoidance parameter to one or more channels of a first frequency band based on identifying the target bandwidth of the channel. In some examples, a channel avoidance parameter may be an example of one or more operational settings of one or more radios or receive/transmit chains of the premises equipment to avoid channels that may be more susceptible to interference in order to decrease a probability that the channels will be selected for Wi-Fi communications with the UEs.

At 440, the premises equipment 204-b may select a channel in a first frequency subband of the second frequency band for the communication link based on (e.g., using) the channel avoidance procedure. In some aspects, the premises equipment 205-b may select the channel in the first frequency subband based on identifying the location of the premises equipment 205-b at 410, identifying the backhaul communication link and/or communication link at 415 and 420, identifying the operational state of the second frequency band at 425, identifying the target bandwidth at 430, performing the channel avoidance procedure at 435, or any combination thereof. For example, the premises equipment 205-b may select the channel in the first frequency subband based on identifying that the communication link operates using the second frequency band concurrently with the backhaul communication link operating using the first frequency band.

In some aspects, the premises equipment 205-b may select the channel in the first frequency subband of the second frequency band based on applying one or more channel avoidance parameters to one or more other frequency subbands (e.g., second frequency subband, third frequency subband) at 435. of the second frequency band. Moreover, in additional or alternative aspects, the premises equipment 205-b may select the channel in the first frequency subband based on applying one or more channel avoidance parameters to one or more other channels in the first frequency subband at 435.

In some aspects, the premises equipment 205-b may select the channel in the first frequency subband at 440 based on determining a frequency distance between the first frequency band (e.g., N79 band) and the second frequency band (e.g., WLAN 5 GHz band) satisfies a threshold. For example, as noted previously herein, the premises equipment 205-b may identify a frequency distance (e.g., bandwidth of a guard band) between the first frequency band (e.g., N79 band) and the second frequency band (e.g., WLAN 5 GHz band) . In this example, the premises equipment 205-b may compare the frequency distance to a threshold, and select the channel based on determining that the frequency distance satisfies a threshold. In some cases, the premises equipment 205-b may determine that the frequency distance satisfies the threshold when the frequency distance is greater than the threshold.

At 445, the premises equipment 205-b may communicate with the UE 115-c using the channel of the first frequency subband within the second frequency band. In some aspects, the premises equipment 205-b may communicate with the UE 115-c using the channel within the second frequency band based on selecting the channel at 440. Moreover, the premises equipment 205-b may communicate with the UE 115-c using the channel within the second frequency band based on identifying the location of the premises equipment 205-b at 410, identifying the backhaul communication link and/or communication link at 415 and 420, identifying the operational state of the second frequency band at 425, identifying the target bandwidth at 430, performing the channel avoidance procedure at 435, or any combination thereof.

At 450, the premises equipment 205-b may communicate with the base station 105-b using the backhaul communication link in the first frequency band. In some aspects, the premises equipment 205-b may communicate with the base station 105-b using the backhaul communication link based on selecting the channel at 440. Moreover, the premises equipment 205-b may communicate with the base station 105-b using the backhaul communication link based on identifying the location of the premises equipment 205-b at 410, identifying the backhaul communication link and/or communication link at 415 and 420, identifying the operational state of the second frequency band at 425, identifying the target bandwidth at 430, performing the channel avoidance procedure at 435, or any combination thereof.

In some aspects, the premises equipment 205-b may communicate with the UE 115-c and the base station 105-b concurrently. In this regard, the communications with the UE 115-c over the communication link illustrated at 445 and the communications with the base station 105-b over the backhaul communication link illustrated at 450 may occur concurrently such that the communications at least partially overlap in the time domain. For example, the premises equipment 205-b may communicate with the base station 105-b using the backhaul communication link in the first frequency band during a first duration, and may communicate with the UE 115-b using the communication link in the second frequency band during a second duration. In this example, the first duration may at least partially overlap with the second duration such that the communications with the UE 115-b and the base station 105-b take place concurrently during the duration of the overlap between the first duration and the second duration.

Techniques described herein may improve the performance and reliability of the premises equipment 205-b (e.g., CPE) in the context of FWA. In particular, by performing channel avoidance procedures, techniques described herein may reduce or eliminate potential interference between a backhaul communication link (e.g., 5G link) with the base station 105-b and a communication link (e.g., Wi-Fi link, WLAN 5 GHz link) with a UE 115-b supported by the premises equipment 205-b. In this regard, techniques described herein may enable the premises equipment 205-b to select efficient channels for Wi-Fi communication which reduce potential interference attributable to 5G communications supported by the premises equipment 205-b, thereby providing reliable FWA.

For example, by reducing interference in the communication links (e.g., Wi-Fi communication links) between the premises equipment 205 and a UE 115, the premises equipment 205 may reduce the number of retransmissions used to successfully communicate with the UE 115, correspondingly reducing a number of times the processor ramps up processing power and turns on processing units to handle signal transmission and reception.
