MEASUREMENT REPORTING TIMER

TECHNICAL FIELD

Embodiments of the présent disclosure are directed to wireless communications and, more particularly, to variable length timers for reporting radio measurement results.

BACKGROUND

Generally, ail terms used herein are to be interpreted according to their ordinary meaning in the relevant technical field, unless a different meaning is clearly given and/or is implied from the context in which it is used. Ail references to a/an/the element, apparatus, component, means, step, etc. are to be interpreted openly as referring to at least one instance of the element, apparatus, component, means, step, etc., unless explicitly stated otherwise. The steps of any methods disclosed herein do not hâve to be performed in the exact order disclosed, unless a step is explicitly described as following or preceding another step and/or where it is implicit that a step must follow or précédé another step. Any feature of any of the embodiments disclosed herein may be applied to any other embodiment, wherever appropriate. Likewise, any advantage of any of the embodiments may apply to any other embodiments, and vice versa. Other objectives, features and advantages of the enclosed embodiments will be apparent from the following description.

Third Génération Partnership Project (3GPP) long term évolution (LTE) includes automatic neighbor relation (ANR), which automatically détermines relationships between network nodes, such as eNBs. The relations may be used for various purposes, such as establishing connections between eNBs, supporting mobility, load balancing, dual connectivity, etc. Thus, ANR may significantly reduce planning and operation costs for operators.

In LTE, a user equipment (UE) detects cells based on their primary/secondary synchronization signais (PSS/SSS), which encode a physical cell identifier (PCI). An important property of the synchronization signais is that the UE autonomously detects neighbor cell IDs from an acquired PSS/SSS (i.e., the network does not need to provide a neighbor cell list). UEs typically detect and measure neighbor cells by sampling a short time window (e.g., 5 ms) on the frequency of the neighbor (which may be the same or different frequency from the serving cell) and search (possibly offline) for PSS/SSS occurrences within that sample. For each detected PSS/SSS, the UE may perform a measurement using a cell reference signal (CRS) corresponding to the PCI. The resuit is a list of neighbor cell identities and corresponding measurement s amples.

After the UE performs measurements, mobility events can trigger the transmission of measurement reports. Based on these reports, the serving eNB identifies that a given PCI belongs to a neighbor eNB and may trigger a handover préparation procedure. The serving eNB maintains a neighbor relation table (NRT) that maps locally unique identifiers (e.g., the PCIs in LTE) with globally unique identifiers (e.g., the E-UTRAN cell global identifier (E-CGI)). LTE defines E-CGI as a combination of public land mobile network (PLMN) ID (combination of country code and network code) and enhanced cell identity (ECI) (combination of eNB ID and cell ID).

Given the benefits of ANR in LTE, ANR will continue to be an important feature in next génération radio system (NR). Challenging NR requirements may resuit in a greater emphasis on the need for seamless mobility than in legacy radio access technologies (RATs), which further increases the importance of automatic relation establishment in NR. NR supports ANR using LTE procedures as a baseline, and the LTE inter-RAT ANR framework is extended for NR.

ANR reporting includes cell global identifier (CGI) reporting. The UE is requested to read neighbor cells System information (including global cell identity) to assist an eNB/gNB in building neighbor relation information. CGI measurement is normally requested when the UE has reported an unknown PCI (i.e., an unknown neighbor cell) to the source node managing the connection. PCI information is included in ail the UE measurement reports which may hâve been initiated for different purposes. When the eNB/gNB has required information about a neighbor cell, the information is stored and may be used to setup an X2/Xn connection between the nodes. As described above, the X2/Xn connection may be used for several different procedures, such as handover, dual connectivity setup, etc.

FIGURE 1 is a block diagram illustrating an example of dual connectivity and neighbor node CGI retrieval. UE 10 may be connected to a master node (MN) 20, and optionally connected to one or more secondary nodes (SN) 30 for dual/multiple connectivity. UE 10 may retrieve the CGI of a neighbor node (NN) 40.

In LTE, upon receiving a measurement configuration including a reportConflg information element with its purpose set to reportCGI, the UE starts a timer referred to as T321 and tries to acquire CGI information of the requested cell. If the UE succeeds while the timer is running, the UE includes CGI information in a reportCGI message (which is an example of a measurement report) and sends the message to the network. If the UE fails to detect the CGI info within the duration of T321 (i.e., upon the expiry of T321), the UE sends a reportCGI message with an empty CGI information field. In LTE, T321 is pre-configured in the spécification 3GPP

TS 36.331.

In LTE, the value of T321 is set differently for intra-RAT ANR and inter-RAT ANR. If the ANR measurement is associated with intra-RAT ANR, T321 is set with a shorter time value, because the UE has previously been connected to the RAT.

Further, in existing LTE, if the UE is able to use autonomous gaps in acquiring System information from a neighbor cell (i.e., si-RequestForHO is included in the reportConfig), then the UE may use a shorter time value for T321.

NR includes varions deployment scénarios. For example, multiple variations exist for deploying a 5G network with or without interworking with existing LTE and evolved packet code (EPC). Some options are illustrated in FIGURE 2.

FIGURE 2 is a block diagram illustrating varions LTE and NR interworking options.

Option 3 illustrated in FIGURE 2 may be referred to as EN-DC (EUTRAN-NR Dual Connectivity). In the illustrated network deployment, dual connectivity is used between NR and LTE where a master node is LTE and a secondary node is NR. The RAN node (gNB) supporting NR may not hâve a control plane connection to the core network (EPC). Instead, the gNB may rely on the LTE as master node (MeNB). This may be referred to as non-standalone (NSA) NR and 5GCN is not included in this deployment. In the illustrated example, the functionality of an NR cell is limited to use by connected mode UEs as a booster and/or diversity leg, but a UE cannot camp on the NR cells.

Using 5G core network (5GCN), other options are available. For example, illustrated option 2 supports stand-alone (SA) NR deployment where the gNB is connected to 5GCN. Similarly, LTE can also be connected to 5GCN using illustrated option 5. In these examples, both NR and LTE are part of the NG-RAN and connected to 5GCN.

LTE networks include System information divided into a master information block (MIB) and a number of System information blocks (SIBs). The MIB includes a limited number of most essential and most frequently transmitted parameters that are needed to acquire other information from the cell and is transmitted on a broadcast channel (BCH).

In particular, the information needed for ANR, such as CGI, tracking area code (TAC) and PLMN list, is broadcasted in System information block type 1 (SIB1). Because NR can be deployed along with LTE (more precisely as EN-DC described above), an NR cell may skip SIB1 transmission. To assist a UEs in recognizing the absence of a SIB1 transmission, absence information is broadcasted in the MIB. More precisely, the pdcch-ConfigSIB 1 information element (IE) is mandatory in MIB1 and one code-point (e.g., all-zeros) is assigned if SIB1 is not présent. The UE, by decoding the MIB content, détermines whether to expect SIB1 transmission.

NR may be deployed in low frequency ranges as well as high frequency ranges. 3GPP Rel 15 NR (38.104, section 5.2) describes support in two frequency ranges, FRI (450 MHz - 6 GHz) and FR2 (24.25 GHz - 52.6 GHz).

SUMMARY

Based on the description above, there currently exist certain challenges for measurement reporting timer sélection. For example, the T321 timer is pre-configured in Third Génération Partnership Project (3GPP) long term évolution (LTE). T321 is different for different cells for which to report CGI and possibly different depending on UE category. T321 also dépends on whether the UE may use autonomous gaps. The T321 timer provides the UE with time for frequency tuning and retuning back to the serving carrier and radio access technology (RAT) in case the reporting includes a cell at a different frequency and/or RAT.

Fifth génération (5G) new radio (NR), however, includes a diverse range of deployments and new use cases. These include, for example, inter-RAT Dual Connectivity between LTE and NR (referred to as EN-DC when LTE is connected to the evolved packet core (EPC), but also comprising other options such as NR as an anchor and LTE as booster or, LTE as booster but connected to 5GC). These make the current solution non-suitable.

For example, when a UE is configured for dual connectivity with two active transceivers, then the required time for cell global identifier (CGI) reporting may dépend on which transceiver the UE will use for CGI retrieval. This is not defïned in the current spécification. Setting an overly conservative timer may lead to an unnecessarily long wait for its expiry when a UE is having a problem acquiring the CGI. This may be a likely event in NR because NR may include Non-Standalone (NSA) cells not broadcasting SIB1 (i.e., not broadcasting CGI).

Another example includes NR synchronization signal blocks (SSBs) where the associated system information transmitting the CGI is in a different frequency. Because this scénario can hâve a multitude of flavors, fixing a time appropriate for ail cases without being too conservative is difficult.

NR does not currently specify a solution for the CGI reporting problems described above, and nothing spécifie regarding the timer T321. LTE spécifiés the following values depending on different conditions.

For EUTRA frequencies, if the si-RequestForHO information element is included (when the field is included, the UE is allowed to use autonomous gaps in acquiring system information from the neighbor cell, applies a different value for T321, and includes different fields in the measurement report), then a Category 0 UE uses a T321 timer value of 190 ms and ail other UEs use a value of 150 ms. If si-RequestForHO is not included, then frequency division duplex (FDD) UEs use a T321 timer value of 1 second and time division duplex (TDD) UEs use a value of 2 seconds.

For UTRA frequencies, if the si-RequestForHO information element is included, then a Category 0 UE uses a T321 timer value of 190 ms and ail other UEs use a value of 150 ms. If siRequestForHO is not included, then ail UEs use a value of 8 seconds. For any other cases not specified above, the T321 timer value is 8 seconds.

Certain aspects of the présent disclosure and their embodiments may provide solutions to these or other challenges. Particular embodiments address measurement reporting timer sélection (^e-g·, T321) for neighbor node CGI retrieval depending on different criteria known by the network (e.g., duration for CGI acquisition based on frequency range of neighbor cell, RAT of neighbor cell, selected transceiver, etc.). In some embodiments, one criterion is the current UE transceiver configuration when the UE supports dual or multiple connectivity with a master node and one or more secondary nodes.

According to some embodiments, a method performed by a wireless device for measurement reporting comprises: receiving an instruction to perform measurement reporting for a neighbor cell; determining, based at least on a RAT of the neighbor cell and a frequency range of the neighbor cell, a measurement reporting timer value for performing the measurement reporting; and measuring a radio signal of the neighbor cell during the time specified by the determined measurement reporting timer value.

DETAILED DESCRIPTION

Based on the description above, there currently exist certain challenges for measurement reporting timer sélection in fifth génération (5G) new radio (NR). For example, the T321 timer is pre-configured in Third Génération Partnership Project (3GPP) long term évolution (LTE). The preconfigured value may vary for different cells, for different UE categories, whether the UE may use autonomous gaps, etc. 5G NR, however, includes a diverse range of deployments and new use cases that make the current solution non-suitable. NR does not currently specify a solution for the timer sélection problems described above.

Certain aspects of the présent disclosure and their embodiments may provide solutions to these or other challenges. Particular embodiments address measurement reporting timer sélection (e.g., T321) for neighbor node cell global identifier (CGI) retrieval depending on different criteria known by the network (e.g., duration for CGI acquisition based on frequency range of neighbor cell, radio access technology (RAT) of neighbor cell, selected transceiver, etc.).

Certain aspects of the présent disclosure and their embodiments may provide solutions to these or other challenges. Particular embodiments optimize timer value sélection (e.g., T321) for cases when a UE is connected to more than one node. The UE has freedom to select the most appropriate transceiver for CGI retrieval. In some embodiments, a UE may receive transceiver sélection indication control from the network. The UE may report the selected timer value to the network.

Particular embodiments are described more fully with reference to the accompanying drawings. Other embodiments, however, are contained within the scope of the subject matter disclosed herein. The disclosed subject matter should not be construed as limited to only the embodiments set forth herein; rather, these embodiments are provided by way of example to convey the scope of the subject matter to those skilled in the art.

CGI reporting capabilities may dépend on the configured RAT and/or frequency carrier(s) of the serving cell and the RAT and/or frequency carrier of a neighbor node. Particular embodiments apply to dual or multiple connectivity UEs.

Measurement reporting T321 timer values are pre-configured in LTE. A spécification defines different T321 timer values for different circumstances. The circumstances differ in terms of the neighbor node RAT and whether the UE may use autonomous gaps where the UE disregards transmitted data and/or configured uplink resources to retrieve CGI.

In some embodiments, the pre-configured T321 timer values include the transceiver configuration of the UE. The T321 timer value may dépend on the RAT of the selected transceiver for CGI retrieval. For example, a shorter T321 timer value may be configured if the RAT of the selected transceiver for CGI retrieval is the same as the RAT of the neighbor node.

In some embodiments, the T321 timer value dépends on the frequency range of the neighbor node. For example, if the neighbor node is NR, then the T321 timer value may dépend on whether the neighbor node is operating in FRI or FR2. As a particular example, the UE may select a timer value of 2 seconds for FRI and 16 seconds for FR2.

In some embodiments, the T321 timer value dépends on the combination of the frequency range of the selected transceiver for CGI retrieval and the frequency range of the neighbor node. For example, in some configurations the selected transceiver for CGI retrieval may be in NR FRI or FR2 and the frequency range of the neighbor node is operating in FRI or FR2. Another example is a configuration where the selected transceiver for CGI retrieval may be in LTE and the frequency range of the neighbor node is operating in FRI or FR2. Another configuration includes the selected transceiver for CGI retrieval may be in NR FRI or FR2 and the neighbor node is operating in LTE.

In some embodiments, the UE is configured by a connected node (e.g., master gNB, secondary gNB, etc.) with T321 timer values. The configured values may comprise case-based values.

Some embodiments define a UE category based on its transceiver architecture (i.e., a shorter timer is defined for UEs capable of processing CGI faster because they hâve dual transceiver architecture).

In some embodiments, a UE is configured with two or more transceivers. The UE can select which transceiver to use for CGI retrieval.

In particular embodiments, the sélection dépends on the frequency range of the transceivers and the RAT of the neighbor node. As one example, a UE may be configured with a transceiver in FRI and a transceiver in FR2, and the neighbor node is operating in FRI. The UE may select a transceiver in FRI for CGI retrieval in case only an FRI configured transceiver can be used to retrieve CGI from a neighbor node operating in FRI.

In another example, the UE is configured with a transceiver in FRI and a transceiver in FR2, and the neighbor node is operating in FR2. The UE may select a transceiver in FR2 for CGI retrieval in case only an FR2 configured transceiver can be used to retrieve CGI from a neighbor node operating in FR2.

In another example, the UE is configured with a transceiver in FRI connected via LTE and a transceiver in FR2, and the neighbor node is operating in FRI. The UE may select a transceiver in FRI for CGI retrieval in case only an FRI configured transceiver can be used to retrieve CGI from a neighbor node operating in FRI.

In yet another example, the UE is configured with a transceiver in FRI connected via LTE and a transceiver in FRI connected via NR, and the neighbor node is operating in FRI. The UE may select either of the transceivers in case only an FRI configured transceiver can be used to retrieve CGI from a neighbor node operating in FRI. An example of a particular embodiments is illustrated in FIGURE 3.

FIGURE 3 is a flow diagram illustrating an example method in a wireless device. At step 310, the UE is pre-configured or optionally configured with one or more T321 timer values. The one or more values may dépend on the RAT of the neighbor node. The one or more values may also dépend on the transceiver configuration of the UE. The values may be referred to as casebased.

In some embodiments, the method may include step 311 where the UE receives a transceiver sélection indication. For example, the UE may receive an indication of which transmitter to use for CGI retrieval from a network node, such as a master gNB or a secondary gNB.

In particular embodiments, the indication spécifiés that the UE shall select a transceiver configured to operate in the same frequency range and/or the same RAT as the neighbor node. The indication may specify that the UE can autonomously select the transceiver for CGI retri eval.

At step 312, the UE selects an appropriate transceiver for CGI retrieval. This can be based on the transceivers that are in use, based on which of the transceivers in use are most appropriate for CGI retrieval of the neighbor node, or based on any other suitable criteria.

At step 314, the UE détermines an applicable T321 time value based on the selected transceiver and the pre-configured or configured case-based T321 timer values. At step 316, the UE considers the determined T321 time value when initiating and conducting CGI retrieval from the neighbor node.

In some embodiments, based on the transceiver sélection and the one or more case-based T321 timer values, the UE détermines the T321 timer value and initiâtes the timer when the UE obtains the CGI reporting request. While the timer is running, the UE tries to retrieve the CGI from the neighbor node and then responds to the neighbor node. If the T321 timer expires, the UE responds with an empty CGI report.

In some embodiments, the method may include step 318 where the UE reports the determined T321 timer value to a connected node, such as a base station (e.g., master node, secondary node, etc.). In general, particular embodiments include a case-based T321 timer value détermination for CGI retrieval based on the selected transceiver and neighbor node configuration.

FIGURE 4 is a flow diagram illustrating signaling, according to particular embodiments. At step 400, case-based T321 timer values are pre-configured or optionally configured by a connected node (e.g., master node or secondary node). At step 410, the master node or a secondary node sends a CGI request to the UE. The request is typically triggered by the UE reporting a physical cell identifier (PCI) of a neighbor node, and the PCI is either not known by a connected node or considered ambiguous.

At step 420, the UE selects an appropriate transceiver for the CGI retrieval. At step 430 the UE retrieves the CGI from the neighbor node and at step 440 reports the CGI to a connected node (e.g., master node or secondary node).

FIGURE 5 is a block diagram illustrating an example wireless device, according to particular embodiments. Wireless device 10 (e.g., UE) includes two or more radio front ends 11, processing circuitry 20, and memory 30. Wireless device 10 is similar to wireless device 110 described in more detail with respect to FIGURE 6. Radio front ends 11, processing circuitry 20 and memory 30 are similar to radio front end 111, processing circuitry 120, and memory 130, respectively, described in more detail with respect to FIGURE 6.

In NR, PCI is encoded in Synchronization Sequence Blocks (SSBs). LTE includes System information associated to the PCI where the UE can obtain CGI, if configured. NR includes some different deployments where SSBs may not be multiplexed with its associated System information. In other words, a UE may need to re-tune its transceiver to acquire CGI associated to a PCI the UE has been configured with, which is different from LTE, and may need a longer timer to acquire CGI. Accordingly, an NR UE may benefit from being configured with longer T321 values.

Another scénario in NR that my need longer times to acquire CGI is when the UE is configured to acquire multiple CGIs. In NR the network may configure the UE with a list of PCIs (or a measurement object) from which it shall acquire and report multiple CGIs, which may take longer than in LTE (even for intra-RAT case) which benefits from having longer T321 timer values.

Another scénario in NR that my lead to longer times to acquire CGI is when a UE needs to perform on demand System information. In other words, a given PCI may not be transmitting CGI and the UE needs to require System information, which would require an additional radio round trip time.

FIGURE 6 illustrâtes an example wireless network, according to certain embodiments. The wireless network may comprise and/or interface with any type of communication, télécommunication, data, cellular, and/or radio network or other similar type of System. In some embodiments, the wireless network may be configured to operate according to spécifie standards or other types of predefined rules or procedures. Thus, particular embodiments of the wireless network may implement communication standards, such as Global System for Mobile Communications (GSM), Universal Mobile Télécommunications System (UMTS), Long Term Evolution (LTE), and/or other suitable 2G, 3G, 4G, or 5G standards; wireless local area network (WLAN) standards, such as the IEEE 802.11 standards; and/or any other appropriate wireless communication standard, such as the Worldwide Interoperability for Microwave Access (WiMax), Bluetooth, Z-Wave and/or ZigBee standards.

Base stations may be categorized based on the amount of coverage they provide (or, stated differently, their transmit power level) and may then also be referred to as femto base stations, pico base stations, micro base stations, or macro base stations.

A base station may be a relay node or a relay donor node controlling a relay. A network node may also include one or more (or ail) parts of a distributed radio base station such as centralized digital units and/or remote radio units (RRUs), sometimes referred to as Remote Radio Heads (RRHs). Such remote radio units may or may not be integrated with an antenna as an antenna integrated radio. Parts of a distributed radio base station may also be referred to as nodes in a distributed antenna System (DAS).

Yet further examples of network nodes include multi-standard radio (MSR) equipment such as MSR BSs, network controllers such as radio network controllers (RNCs) or base station controllers (BSCs), base transceiver stations (BTSs), transmission points, transmission nodes, multi-cell/multicast coordination entities (MCEs), core network nodes (e.g., MSCs, MMEs), O&M nodes, OSS nodes, SON nodes, positioning nodes (e.g., E-SMLCs), and/or MDTs. As another example, a network node may be a Virtual network node as described in more detail below. More generally, however, network nodes may represent any suitable device (or group of devices) capable, configured, arranged, and/or opérable to enable and/or provide a wireless device with access to the wireless network or to provide some service to a wireless device that has accessed the wireless network.

In FIGURE 6, network node 160 includes processing circuitry 170, device readable medium 180, interface 190, auxiliary equipment 184, power source 186, power circuitry 187, and antenna 162. Although network node 160 illustrated in the example wireless network of Figure 1 may represent a device that includes the illustrated combination of hardware components, other embodiments may comprise network nodes with different combinations of components. It is to be understood that a network node comprises any suitable combination of hardware and/or software needed to perform the tasks, features, functions and methods disclosed herein. Moreover, while the components of network node 160 are depicted as single boxes located within a larger box, or nested within multiple boxes, in practice, a network node may comprise multiple different physical components that make up a single illustrated component (e.g., device readable medium 180 may comprise multiple separate hard drives as well as multiple RAM modules).

Similarly, network node 160 may be composed of multiple physically separate components (e.g., a NodeB component and a RNC component, or a BTS component and a BSC component, etc.), which may each hâve their own respective components. In certain scénarios in which network node 160 comprises multiple separate components (e.g., BTS and BSC components), one or more of the separate components may be shared among several network nodes. For example, a single RNC may control multiple NodeB’s. In such a scénario, each unique NodeB and RNC pair, may in some instances be considered a single separate network node. In some embodiments, network node 160 may be configured to support multiple radio access technologies (RATs). In such embodiments, some components may be duplicated (e.g., separate device readable medium 180 for the different RATs) and some components may be reused (e.g., the same antenna 162 may be shared by the RATs). Network node 160 may also include multiple sets of the various illustrated components for different wireless technologies integrated into network node 160, such as, for example, GSM, WCDMA, LTE, NR, WiFi, or Bluetooth wireless technologies. These wireless technologies may be integrated into the same or different chip or set of chips and other components within network node 160.

In any of those embodiments, whether executing instructions stored on a device readable storage medium or not, processing circuitry 170 can be configured to perform the described functionality. The benefits provided by such functionality are not limited to processing circuitry 170 alone or to other components of network node 160, but are enjoyed by network node 160 as a whole, and/or by end users and the wireless network generally.

Radio front end circuitry 192 may couvert the digital data into a radio signal having the appropriate channel and bandwidth parameters using a combination of filters 198 and/or amplifiers 196. The radio signal may then be transmitted via antenna 162. Similarly, when receiving data, antenna 162 may collect radio signais which are then converted into digital data by radio front end circuitry 192. The digital data may be passed to processing circuitry 170. In other embodiments, the interface may comprise different components and/or different combinations of components.

In certain alternative embodiments, network node 160 may not include separate radio front end circuitry 192, instead, processing circuitry 170 may comprise radio front end circuitry and may be connected to antenna 162 without separate radio front end circuitry 192.

FIGURE 8 is a flowehart illustrating an example method in a wireless device for measurement reporting, according to certain embodiments. In particular embodiments, one or more steps of FIGURE 8 may be performed by wireless device 110 described with respect to FIGURE 6.

The method begins at step 812 where a wireless device (e.g., wireless device 110) receives an instruction to perform measurement reporting for a neighbor cell. The measurement reporting may include a CGI report. The neighbor cell RAT may be 5G NR.

At step 814, the wireless device may select a transceiver for performing the measurement reporting. The transceiver sélection may be based on a RAT and/or frequency range of a neighbor cell. The wireless device may détermine the sélection, or the wireless device may receive an indication from a network node of which transceiver to select.

At step 816, the wireless device détermines, based at least on a RAT of the neighbor cell and a frequency range of the neighbor cell, a measurement reporting timer value for performing the measurement reporting.

In some embodiments, determining the measurement reporting timer value comprises determining both a first measurement reporting timer value (e.g., 2 seconds) for a neighbor cell operating at a first frequency range (e.g., 450 Mégahertz to 6 Gigahertz) and a second measurement reporting timer value (e.g., 16 seconds) for a neighbor cell operating at a second frequency range (e.g., 24.25 Gigahertz to 52.6 Gigahertz).

At step 818, the wireless device measures a radio signal of the neighbor cell during the time specified by the determined measurement reporting timer value. The wireless device may send a measurement report to the network node.

The method begins at step 912 where a network node (e.g., network node 160) détermines, based at least on a RAT of the neighbor cell and a frequency range of the neighbor cell, a measurement reporting timer value for performing the measurement reporting.

In particular embodiments, the wireless device comprises two or more transceivers. The method may further comprise selecting one of the two or more transceivers for performing the measurement reporting. Determining the measurement reporting timer value is further based on the selected transceiver. Determining the measurement reporting timer value based on the selected transceiver may comprise determining the measurement reporting timer value based on a frequency range of the selected transceiver or on a RAT of the selected transceiver.

At step 914, the network node transmits the determined measurement reporting timer value to the wireless device (e.g., wireless device 110).

At step 916, the network node may transmit an indication of a selected receiver to the wireless device. In some embodiments, step 916 may be combined with step 914 and both the reporting timer value and the selected receiver may be transmitted to the wireless device together.

Modifications, additions, or omissions may be made to method 900 of FIGURE 9. Additionally, one or more steps in the method of FIGURE 9 may be performed in parallel or in any suitable order.

FIGURE 11 is a schematic block diagram illustrating a virtualization environment 300 in which functions implemented by some embodiments may be virtualized. In the présent context, virtualizing means creating virtual versions of apparatuses or devices which may include virtualizing hardware platforms, storage devices and networking resources. As used herein, virtualization can be applied to a node (e.g., a virtualized base station or a virtualized radio access node) or to a device (e.g., a UE, a wireless device or any other type of communication device) or components thereof and relates to an implémentation in which at least a portion of the functionality is implemented as one or more virtual components (e.g., via one or more applications, components, functions, virtual machines or containers executing on one or more physical processing nodes in one or more networks).

In some embodiments, some or ail of the functions described herein may be implemented as virtual components executed by one or more virtual machines implemented in one or more Virtual environments 300 hosted by one or more of hardware nodes 330. Further, in embodiments in which the virtual node is not a radio access node or does not require radio connectivity (e.g., a core network node), then the network node may be entirely virtualized.

The functions may be implemented by one or more applications 320 (which may altematively be called software instances, virtual appliances, network functions, virtual nodes, virtual network functions, etc.) operative to implement some of the features, functions, and/or benefits of some of the embodiments disclosed herein. Applications 320 are run in virtualization environment 300 which provides hardware 330 eomprising processing circuitry 360 and memory 390. Memory 390 contains instructions 395 exécutable by processing circuitry 360 whereby application 320 is operative to provide one or more of the features, benefits, and/or functions disclosed herein.

Virtualization environment 300, comprises general-purpose or special-purpose network hardware devices 330 eomprising a set of one or more processors or processing circuitry 360, which may be commercial off-the-shelf (COTS) processors, dedicated Application Spécifie Integrated Circuits (ASICs), or any other type of processing circuitry including digital or analog hardware components or spécial purpose processors. Each hardware device may comprise memory 390-1 which may be non-persistent memory for temporarily storing instructions 395 or software executed by processing circuitry 360. Each hardware device may comprise one or more network interface controllers (NICs) 370, also known as network interface cards, which include physical network interface 380. Each hardware device may also include non-transitory, persistent, machine-readable storage media 390-2 having stored therein software 395 and/or instructions exécutable by processing circuitry 360. Software 395 may include any type of software including software for instantiating one or more virtualization layers 350 (also referred to as hypervisors), software to execute virtual machines 340 as well as software allowing it to execute functions, features and/or benefits described in relation with some embodiments described herein.

Virtual machines 340, comprise virtual processing, virtual memory, virtual networking or interface and virtual storage, and may be run by a corresponding virtualization layer 350 or hypervisor. Different embodiments of the instance of virtual appliance 320 may be implemented on one or more of virtual machines 340, and the implémentations may be made in different ways.

During operation, processing circuitry 360 executes software 395 to instantiate the hypervisor or virtualization layer 350, which may sometimes be referred to as a virtual machine monitor (VMM). Virtualization layer 350 may présent a virtual operating platform that appears like networking hardware to virtual machine 340.

As shown in FIGURE 11, hardware 330 may be a standalone network node with generic or spécifie components. Hardware 330 may comprise antenna 3225 and may implement some fimetions via virtualization. Altematively, hardware 330 may be part of a larger cluster of hardware (e.g. such as in a data center or customer premise equipment (CPE)) where many hardware nodes work together and are managed via management and orchestration (MANO) 3100, which, among others, oversees lifecycle management of applications 320.

Virtualization of the hardware is in some contexts referred to as network function virtualization (NFV). NFV may be used to consolidate many network equipment types onto industry standard high-volume server hardware, physical switches, and physical storage, which can be located in data centers, and customer premise equipment.

In the context of NFV, virtual machine 340 may be a software implémentation of a physical machine that runs programs as if they were executing on a physical, non-virtualized machine. Each of virtual machines 340, and that part of hardware 330 that executes that virtual machine, be it hardware dedicated to that virtual machine and/or hardware shared by that virtual machine with others of the virtual machines 340, forms a separate virtual network éléments (VNE).

Still in the context of NFV, Virtual Network Function (VNF) is responsible for handling spécifie network functions that run in one or more virtual machines 340 on top of hardware networking infrastructure 330 and corresponds to application 320 in FIGURE 11.

In some embodiments, one or more radio units 3200 that each include one or more transmitters 3220 and one or more receivers 3210 may be coupled to one or more antennas 3225. Radio units 3200 may communicate directly with hardware nodes 330 via one or more appropriate network interfaces and may be used in combination with the virtual components to provide a virtual node with radio capabilities, such as a radio access node or a base station.

In some embodiments, some signaling can be effected with the use of control System 3230 which may altematively be used for communication between the hardware nodes 330 and radio units 3200.

With reference to FIGURE 12, in accordance with an embodiment, a communication System includes télécommunication network 410, such as a 3GPP-type cellular network, which comprises access network 411, such as a radio access network, and core network 414. Access network 411 comprises a plurality of base stations 412a, 412b, 412c, such as NBs, eNBs, gNBs or other types of wireless access points, each defining a corresponding coverage area 413a, 413b, 413c. Each base station 412a, 412b, 412c is connectable to core network 414 over a wired or wireless connection 415. A first UE 491 located in coverage area 413c is configured to wirelessly connect to, or be paged by, the corresponding base station 412c. A second UE 492 in coverage area 413a is wirelessly connectable to the corresponding base station 412a. While a plurality of UEs 491, 492 are illustrated in this example, the disclosed embodiments are equally applicable to a situation where a sole UE is in the coverage area or where a sole UE is connecting to the corresponding base station 412.

Télécommunication network 410 is itself connected to host computer 430, which may be embodied in the hardware and/or software of a standalone server, a cloud-implemented server, a distributed server or as processing resources in a server farm. Host computer 430 may be under the ownership or control of a service provider or may be operated by the service provider or on behalf of the service provider. Connections 421 and 422 between télécommunication network 410 and host computer 430 may extend directly from core network 414 to host computer 430 or may go via an optional intermediate network 420. Intermediate network 420 may be one of, or a combination of more than one of, a public, private or hosted network; intermediate network 420, if any, may be a backbone network or the Internet; in particular, intermediate network 420 may comprise two or more sub-networks (not shown).

The communication System of FIGURE 12 as a whole enables connectivity between the connected UEs 491, 492 and host computer 430. The connectivity may be described as an overthe-top (OTT) connection 450. Host computer 430 and the connected UEs 491, 492 are configured to communicate data and/or signaling via OTT connection 450, using access network 411, core network 414, any intermediate network 420 and possible further infrastructure (not shown) as intermediaries. OTT connection 450 may be transparent in the sense that the participating communication devices through which OTT connection 450 passes are unaware of routing of uplink and downlink communications. For example, base station 412 may not or need not be informed about the past routing of an incoming downlink communication with data originating from host computer 430 to be forwarded (e.g., handed over) to a connected UE 491. Similarly, base station 412 need not be aware of the future routing of an outgoing uplink communication originating from the UE 491 towards the host computer 430.

FIGURE 13 illustrâtes an example host computer communicating via a base station with a user equipment over a partially wireless connection, according to certain embodiments. Example implémentations, in accordance with an embodiment, of the UE, base station and host computer discussed in the preceding paragraphe will now be described with reference to FIGURE 13. In communication System 500, host computer 510 comprises hardware 515 including communication interface 516 configured to set up and maintain a wired or wireless connection with an interface of a different communication device of communication System 500. Host computer 510 further comprises processing circuitry 518, which may hâve storage and/or processing capabilities. In particular, processing circuitry 518 may comprise one or more programmable processors, application-specific integrated circuits, field programmable gâte arrays or combinations of these (not shown) adapted to execute instructions. Host computer 510 further comprises software 511, which is stored in or accessible by host computer 510 and exécutable by processing circuitry 518. Software 511 includes host application 512. Host application 512 may be opérable to provide a service to a remote user, such as UE 530 connecting via OTT connection 550 terminating at UE 530 and host computer 510. In providing the service to the remote user, host application 512 may provide user data which is transmitted using OTT connection 550.

Communication System 500 further includes base station 520 provided in a télécommunication System and comprising hardware 525 enabling it to communicate with host computer 510 and with UE 530. Hardware 525 may include communication interface 526 for setting up and maintaining a wired or wireless connection with an interface of a different communication device of communication System 500, as well as radio interface 527 for setting up and maintaining at least wireless connection 570 with UE 530 located in a coverage area (not shown in FIGURE 13) served by base station 520. Communication interface 526 may be configured to facilitate connection 560 to host computer 510. Connection 560 may be direct, or it may pass through a core network (not shown in FIGURE 13) of the télécommunication System and/or through one or more intermediate networks outside the télécommunication System. In the embodiment shown, hardware 525 of base station 520 further includes processing circuitry 528, which may comprise one or more programmable processors, application-specific integrated circuits, field programmable gâte arrays or combinations of these (not shown) adapted to execute instructions. Base station 520 further has software 521 stored intemally or accessible via an extemal connection.

Communication system 500 further includes UE 530 already referred to. Its hardware 535 may include radio interface 537 configured to set up and maintain wireless connection 570 with a base station serving a coverage area in which UE 530 is currently located. Hardware 535 of UE 530 further includes processing circuitry 538, which may comprise one or more programmable processors, application-specific integrated circuits, field programmable gâte arrays or combinations of these (not shown) adapted to execute instructions. UE 530 further comprises software 531, which is stored in or accessible by UE 530 and exécutable by processing circuitry 538. Software 531 includes client application 532. Client application 532 may be opérable to provide a service to a human or non-human user via UE 530, with the support of host computer 510. In host computer 510, an executing host application 512 may communicate with the executing client application 532 via OTT connection 550 terminating at UE 530 and host computer 510. In providing the service to the user, client application 532 may receive request data from host application 512 and provide user data in response to the request data. OTT connection 550 may transfer both the request data and the user data. Client application 532 may interact with the user to generate the user data that it provides.

It is noted that host computer 510, base station 520 and UE 530 illustrated in FIGURE 13 may be similar or identical to host computer 430, one of base stations 412a, 412b, 412c and one of UEs 491, 492 of FIGURE 12, respectively. This is to say, the inner workings of these entities may be as shown in FIGURE 10 and independently, the surrounding network topology may be that of FIGURE 12.

In FIGURE 13, OTT connection 550 has been drawn abstractly to illustrate the communication between host computer 510 and UE 530 via base station 520, without explicit reference to any intermediary devices and the précisé routing of messages via these devices. Network infrastructure may détermine the routing, which it may be confîgured to hide from UE 530 or from the service provider operating host computer 510, or both. While OTT connection 550 is active, the network infrastructure may further take decisions by which it dynamically changes the routing (e.g., on the basis of load balancing considération or reconfiguration of the network).

Wireless connection 570 between UE 530 and base station 520 is in accordance with the teachings of the embodiments described throughout this disclosure. One or more of the various embodiments improve the performance of OTT services provided to UE 530 using OTT connection 550, in which wireless connection 570 forms the last segment. More precisely, the teachings of these embodiments may improve the signaling overhead and reduce latency, which may provide faster internet access for users.

A measurement procedure may be provided for the purpose of monitoring data rate, latency and other factors on which the one or more embodiments improve. There may further be an optional network functionality for reconfiguring OTT connection 550 between host computer 510 and UE 530, in response to variations in the measurement results. The measurement procedure and/or the network functionality for reconfiguring OTT connection 550 may be implemented in software 511 and hardware 515 of host computer 510 or in software 531 and hardware 535 of UE 530, or both. In embodiments, sensors (not shown) may be deployed in or in association with communication devices through which OTT connection 550 passes; the sensors may participate in the measurement procedure by supplying values of the monitored quantities exemplified above or supplying values of other physical quantities from which software 511, 531 may compute or estimate the monitored quantities. The reconfiguring of OTT connection 550 may include message format, retransmission settings, preferred routing etc.; the reconfiguring need not affect base station 520, and it may be unknown or imperceptible to base station 520. Such procedures and functionalities may be known and practiced in the art. In certain embodiments, measurements may involve proprietary UE signaling facilitating host computer 510’s measurements of throughput, propagation times, latency and the like. The measurements may be implemented in that software 511 and 531 causes messages to be transmitted, in particular empty or ‘dummy’ messages, using OTT connection 550 while it monitors propagation times, errors etc.
