Description

Method of transmitting data packets using configuration authorized transmission resources and associated communication device, medium and chip
Technical Field
The present disclosure relates to the field of communications, and more particularly, to a method of transmitting data packets using configuration authorization transmission resources and associated communication devices, media and chips.
Background
During the process of accessing the network device or after accessing the network device, the terminal device may perform a Radio Resource Control (RRC) establishment procedure with the network device. After the RRC connection is established, the RRC state of the terminal device is an RRC CONNECTED (RRC _ CONNECTED) state. Subsequently, the RRC state of the terminal device may transition among: an RRC IDLE (RRC IDLE) state, an RRC CONNECTED state, and an RRC INACTIVE (RRC INACTIVE) state. In the RRC _ CONNECTED state, the terminal device may send specific data of the terminal device or unicast data of the terminal device to the network device through an uplink data channel, for example, a Physical Uplink Shared Channel (PUSCH), according to dynamic scheduling (DG) of the network device or unlicensed scheduling (CG) configured by the base station. Alternatively, the terminal device may receive specific data of the terminal device or unicast data of the terminal device from the network device through a downlink data channel, for example, a Physical Downlink Shared Channel (PDSCH). In the RRC _ IDLE state, the connection between the terminal device and the access network and the connection between the terminal device and the core network are released. At this time, the terminal device may receive a broadcast channel, a paging message, system information, and the like from the network device, but may not perform unicast data transmission with the network device, for example, may not receive the terminal device-specific PDSCH from the terminal device or may not transmit the terminal device-specific PUSCH to the network device. At RRC _ INACTIVE, the connection between the terminal device and the access network is released, but the connection between the terminal device and the core network may be maintained. In this case, the terminal device may receive a broadcast/multicast packet such as a broadcast message, a paging message, and system information from the network device, or may perform limited unicast data transmission with the network device.

The periodicity of the second set of configuration grant resources is less than the periodicity of the first set of configuration grant resources. The terminal device sends the initial transmission of the data packet to the network device by using the first configuration authorization resource set. After the initial transmission, the terminal device sends another transmission of the data packet to the network device using the second set of configuration granted resources. In this way, when the terminal has a plurality of data packets to be sent, the first data packet is sent through the first configuration authorized resource, and the subsequent data packets are sent through the second configuration authorized resource, so that the time delay of data packet transmission can be reduced.

As described above, during RRC _ INACTIVE, the terminal device may perform limited unicast data transmission with the network device, for example, the terminal device sends a unicast small data packet (small data) to the network device and/or receives a unicast small data packet sent by the network device. The feature that the terminal device is in the RRC _ INACTIVE state is that the network device retains the registration information of the terminal, but the terminal suspends most of the air interface behaviors with the base station, such as suspending monitoring of scheduling information (i.e., receiving and scheduling the PDCCH for unicast transmission of the terminal device), sending a scheduling request, RRM (Radio Resource Management) measurement, beam maintenance, and the like. Generally, the RRC _ INACTIVE state is a state in which the terminal saves power, compared to the RRC _ CONNECTED state.
According to the conventional technology, the 5G NR terminal device in the RRC _ INACTIVE state does not support unicast data transmission, that is, the terminal device needs to resume the RRC connection to enter the RRC _ CONNECTED state before unicast data transmission can be performed. However, in some scenarios, the data packets that need to be transmitted by the terminal device in the RRC _ INACTIVE state are usually very small (i.e., small data, small packet data), and the signaling required by the terminal device to enter the RRC _ CONNECTED state from the RRC _ INACTIVE state is even larger than the small packet data, which results in unnecessary power consumption and signaling overhead. Specific scenes can cover related services of the smart phone, such as WeChat, QQ instant messages, application heartbeat packets or push messages; and related services of non-smart phones, such as periodic data of wearable devices, e.g., heartbeat packets, periodic readings sent by industrial wireless sensor networks, smart meters, and the like. Packets of less than 300 bytes can now be considered a small packet. Or, it can be considered that a packet that can be completely transmitted in one slot is a small packet (for example, 5M bandwidth resource, one slot of 30kHz SCS, if QPSK modulated, can transmit about 500 bytes); or may be defined as user plane and/or control plane packets sent in RRC _ INACTIVE state.
Therefore, the terminal equipment is supported to directly transmit the packet in the RRC _ INACTIVE state without state conversion, and the signaling overhead and the power consumption of the packet transmission of the terminal equipment in the RRC _ INACTIVE state can be remarkably reduced, wherein the packet transmission of the terminal equipment in the RRC _ INACTIVE state is mainly divided into packet transmission (RA-SDT) based on random access and packet transmission (CG-SDT) based on configuration authorization.
The New Radio (NR) introduces the concept of Synchronization Signal Block (SSB), which is periodically broadcast by network devices in SSB bursts. One SSB burst period includes N SSBs, denoted by indexes 0 through N-1. One SSB burst period may be 5, 10, 20ms, etc., and the network device sends all SSBs for a round in 1 SSB burst period. The protocol does not limit the beam (transmission filter) used by the network device to transmit the SSB, and the network device implements the SSB beam by using an analog beam, a digital beam, or a digital-analog mixed beam. The CG resource and the SSB in the RRC _ INACTIVE state may be configured by the network to have a corresponding relationship, so that the network may know partial channel information of the terminal device on a specific resource, and may receive an uplink data packet sent on the CG resource by using a better receiving beam (also referred to as a receiving filter), thereby reducing network blind detection and improving network receiving performance.
Although the CG-based transmission scheme can save energy consumption overhead and signaling overhead and reduce transmission delay for the terminal device, for the base station side, once a CG resource, for example, multiple sets of CG resources are configured, no matter whether the terminal device sends uplink information on a certain CG resource, the network device must detect a signal on the resource, and there is a larger detection overhead for the network device compared to scheduling transmission. In addition, if the network device configures a set of CG-SDT resources with a long period to the terminal device for the purpose of service features or reducing detection overhead, the service delay is easily large, especially when the terminal device has more than one data packet to transmit. If it is considered that different CG periods are mapped to different SSBs, since the subsequent transmission of the CG-SDT usually selects the same SSB as the initial transmission of the CG-SDT, it is necessary to wait for a longer time before having a CG resource corresponding to the next same SSB, resulting in a larger service delay.
In response to the above problems, as well as other potential problems, embodiments of the present disclosure are directed to transmitting data packets using CG resources. The network equipment configures a first CG resource set and a second configuration authorization resource set for the terminal equipment. The periodicity of the second set of CG resources is less than the periodicity of the first set of CG resources. The terminal device sends an initial transmission of the data packet using the first set of CG resources. After the initial transmission, the terminal device sends another transmission of the data packet using the second set of CG resources. In this way, the detection overhead of the network device is reduced, and the transmission delay is reduced.

Example embodiments of the present disclosure will be discussed in detail below with reference to the accompanying drawings. For ease of discussion, the flow of data processing and signaling interactions between communication entities according to an example embodiment of the present disclosure will be described with reference to the example communication environment of fig. 1. It should be understood that example embodiments of the present disclosure may be similarly applied in other communication environments.
Fig. 2 provides a schematic diagram of a flow of an exemplary communication method 200. Method 200 is implemented at a terminal device, for example, terminal device 110-1. It is to be understood that the following description of method 200 is merely a general description of an embodiment.
At block 210, terminal device 110-1 receives a first configuration from network device 120. For example, terminal device 110-1 may receive the first configuration from network device 120 via RRC signaling. After receiving the first configuration, terminal device 110-1 may enter RRC _ INACTIVE state and perform transmission of data packets in RRC _ INACTIVE state. Alternatively, terminal device 110-1 may enter the RRC IDLE state after receiving the first configuration.
The first configuration indicates a first set of Configuration Grant (CG) resources for transmitting data. For example only, as shown in fig. 3A, the first CG resource set may include a CG resource set 310 comprising: resource 310-1, and resource 310-3. The period of the first CG resource set is 3100. It is to be appreciated that the number of resources shown in fig. 3A is merely exemplary and not limiting, and that the first CG resource may include any suitable number of resources.
The first set of CG resources may be type 1 (type 1) CG resources. The term "type 1 (type 1) CG resource" refers to an uplink grant provided by RRC and is stored as a configured uplink grant, wherein UL data transmission is based on RRC reconfiguration without any layer 1 (L1) signaling. The RRC signaling provides the terminal device with authorization configuration through higher layer parameters (e.g., "ConfiguredGrantConfig"). In some embodiments, the first configuration may comprise a resource configuration. Alternatively or additionally, the first configuration may also comprise a transmission parameter configuration. As an example, the first configuration may include one or more of: a period of the first CG resource, an open-loop power control parameter, a waveform, a redundancy version, a repetition number, a frequency hopping pattern, a resource allocation type, a number of hybrid automatic retransmission processes, a demodulation reference signal (DMRS) information parameter, a Modulation Coding Scheme (MCS) table, a resource block group size, a time domain resource, a frequency domain resource, or a modulation coding scheme. The first configuration may also include a configured scheduled radio network temporary identifier (CS-RNTI) for the retransmission. Additionally, the first configuration may include a time domain parameter of a start symbol and an allocation length.
At block 220, terminal device 110-1 receives a second configuration from network device 120. The second configuration indicates a second set of CG resources for transmitting data. For example only, as shown in fig. 3A, the second set of CG resources may include a set of CG resources 320 including resource 320-1, and resource 320-3. The period of the second CG resource set is 3200. It is to be appreciated that the number of resources shown in fig. 3A is merely exemplary and not limiting, and that the second CG resource may include any suitable number of resources. The periodicity of the second set of CG resources is less than the periodicity of the first set of CG resources. In this way, the delay of transmission can be reduced.
At block 230, terminal device 110-1 sends an initial transmission of the data packet to network device 120 using the first set of CG resources. The term "initial transmission" refers to the first transmitted data packet, which may be considered to trigger the start of an RRC procedure. The initial transmission may also include information indicating that there are data packets to be sent. For example, the initial transmission may include a Buffer State Report (BSR).
Terminal device 110-1 may receive feedback information for the initial transmission from the network device. For example, the feedback information may be an Acknowledgement (ACK) message for the initial transmission. Alternatively, the feedback information may be a non-acknowledgement (NACK) message for the initial transmission. In some embodiments, the feedback information may indicate a mapping between the second set of CG resources and the synchronization signal block.
Note that the order of blocks 220 and 230 shown in fig. 2 is merely exemplary. For example, in some embodiments, terminal device 110-1 may receive the second configuration and then send an initial transmission of a data packet. Alternatively, in other embodiments, terminal device 110-1 may send the initial transmission of the data packet before receiving the second configuration.
In some embodiments, the second set of CG resources may be type 1CG resources. For example, the second configuration may be in the same RRC signaling as the first configuration. In some embodiments, the second configuration includes an activation condition for activating the second set of CG resources. The activation condition may also be preconfigured at the terminal device, e.g. specified in the communication protocol. In some embodiments, the activation condition may include: the terminal equipment sends the initial transmission of the data packet by utilizing the first configuration authorization resource set, and the initial transmission indicates that information to be sent by the data packet exists. The activation condition may further include: the terminal equipment sends the initial transmission of the data packet in the random access process, and the initial transmission indicates that the information to be sent by the data packet exists. In other embodiments, the activation condition may further include the terminal device receiving feedback information for the data packet, where the feedback information indicates that the terminal device activates the second set of configuration authorized resources.
Alternatively, as described above, the terminal device may first send an initial transmission of a data packet and then receive the second configuration. In this case, the second configuration may be included in the feedback information for the initial transmission. In the case where the second set of CG resources are type 1CG resources, the second configuration may include one or more of: a period of the second CG resource, an open-loop power control parameter, a waveform, a redundancy version, a repetition number, a frequency hopping pattern, a resource allocation type, a number of hybrid automatic repeat requests, a demodulation reference information parameter, a modulation coding scheme table, a resource block group size, a time domain resource, a frequency domain resource, or a modulation coding scheme.
Alternatively, the second set of CG resources may be type2 (type 2) CG resources. In type2, additional L1 signaling (downlink control information, DCI) is introduced, where the uplink is activated by DCI carrying UL grant configuration parameters. And activating and deactivating type2CG resources through DCI scrambled by CS-RNTI. RRC signaling provides only partial parameters (e.g., "ConfiguredGrantConfig"). DCI signaling may enable fast modification of partial CG transmission parameters. In this way, flexibility in CG parameter configuration and transmission is achieved. In this case, the second configuration may be in the same RRC signaling as the first configuration. The RRC signaling may include at least one of the following parameters: . . The parameters of the second configuration include: a period of the second CG resource, an open loop power control parameter, a waveform, a redundancy version, a repetition number, a frequency hopping pattern, a resource allocation type, a number of hybrid automatic repeat request processes, a demodulation reference information parameter, a modulation coding scheme table, or a resource block group size, wherein a part of the second configured parameter is transmitted in RRC signaling, and another part is transmitted in DCI activating a type2CG resource. For example, the other part of the parameters may be transmitted in the CS-RNTI scrambled DCI. For example, terminal device 110-1 receives an activation indication from network device 120 to activate the second set of CG resources. For example, the activation indication may be in DCI. The activation indication may also be in the feedback information for the initial transmission. Alternatively, the activation indication may be in a paging message. The DCI may include one or more of the following parameters: time domain resources, frequency domain resources, DMRS, or MCS.
In some embodiments, the first configuration may include one or more first CG resource sets. For example only, as shown in fig. 3B, the first configuration may indicate a set of CG resources 310 as well as a set of CG resources 330.CG resource set 330 includes resource 330-1, and resource 330-3.CG resource set 330 has a period of 3300. In some embodiments, period 3100 may have the same value as period 3300. Alternatively, period 3100 may have a different value than period 3300. It will be appreciated that the first configuration may include any suitable number of first CG resource sets.
In some embodiments, the second configuration may include one or more second sets of CG resources. For example only, as shown in fig. 3B, the second configuration may indicate a set of CG resources 320 and a set of CG resources 340.CG resource set 340 includes resource 340-1, and resource 340-3. The CG resource set 340 has a periodicity of 3400. In some embodiments, period 3200 may have the same value as period 3400. Alternatively, period 3200 may have a different value than period 3400. It will be appreciated that the second configuration may include any suitable number of sets of second CG resources. In some embodiments, the second CG resource set may also be used for downlink semi-static transmission, thereby reducing detection overhead of the terminal device.
At block 240, after the initial transmission, terminal device 110-1 sends another transmission of the data packet to network device 120 using the second set of CG resources. The other transmission is a transmission of a data packet following the initial transmission. In some embodiments, terminal device 110-1 may receive an update indication from network device 120 to update the second set of CG resources. The update indication may be received via DC. The update indication may also be received via higher layer signaling, e.g., media access control element (MAC CE) or RRC signaling. Terminal device 110-1 may receive a deactivation indication from network device 120 to deactivate the second set of CG resources. Similarly, the deactivation indication may be received via one of DCI, MAC CE, or RRC signaling. In other embodiments, terminal device 110-1 may receive indication information from network device 120 indicating that the second set of CG resources remain active. The indication information may also be received via one of DCI, MAC CE, or RRC signaling. In some embodiments, the indication information further includes another mapping between the second set of CG resources and the synchronization signal block.
FIG. 4 provides a schematic illustration of the flow of an exemplary data processing method 400. Method 400 is implemented at a network device, such as network device 120. It is to be understood that the following description of method 400 is merely a general description of an embodiment.
At block 410, network device 120 sends a first configuration to terminal device 110-1. For example, network device 120 may send the first configuration to terminal device 110-1 via RRC signaling. The first configuration indicates a first set of CG resources for transmitting data. In some embodiments, the first set of CG resources may be type 1CG resources. In this case, the content included in the first configuration is the same as that described with reference to fig. 2, and is not described again here.
At block 420, network device 120 sends the second configuration to terminal device 110-1. The second configuration indicates a second set of CG resources for transmitting data. For example only, the periodicity of the second set of CG resources is less than the periodicity of the first set of CG resources. In this way, the delay of transmission can be reduced.
At block 430, network device 120 receives an initial transmission of a data packet from end device 110-1 over the first set of CG resources. The initial transmission may also include information indicating that there are packets to be sent. For example, the initial transmission may include a Buffer State Report (BSR).
Network device 120 may send feedback information for the initial transmission to the terminal device. For example, the feedback information may be an ACK message for the initial transmission. Alternatively, the feedback information may be a NACK message for the initial transmission. In some embodiments, the feedback information may indicate a mapping between the second set of CG resources and the synchronization signal block.
Note that the order of blocks 420 and 430 shown in fig. 4 is merely exemplary. For example, in some embodiments, network device 120 may first send the second configuration and then receive the initial transmission. Alternatively, in other embodiments, network device 120 may receive the initial transmission before sending the second configuration.
In some embodiments, the second set of CG resources may be type 1CG resources. For example, the second configuration may be in the same RRC signaling as the first configuration. The second configuration includes an activation condition for activating the second CG resource set. Alternatively, as described above, network device 120 may receive the initial transmission before sending the second configuration. In this case, the second configuration may be included in the feedback information for the initial transmission. In the case that the second CG resource set is a type 1CG resource, the content included in the second CG resource set is the same as that described with reference to fig. 2, and will not be described herein again. Alternatively, the second set of CG resources may be type2CG resources. In this case, the second configuration may be in the same RRC signaling as the first configuration. The contents included in the second configuration are the same as those described with reference to fig. 2, and are not described again here.
Network device 120 may send an activation indication to terminal device 110-1 to activate the second set of CG resources. For example, the activation indication may be in the DCI. The activation indication may also be in the feedback information for the initial transmission. Alternatively, the activation indication may be in a paging message. The activation indication may include one or more of: time domain resources, frequency domain resources, DMRS, or MCS.
In some embodiments, the first configuration may include one or more first CG resource sets. It will be appreciated that the first configuration may include any suitable number of first CG resource sets. In some embodiments, the second configuration may include one or more second CG resource sets. It will be appreciated that the second configuration may include any suitable number of sets of second CG resources.
At block 440, after the initial transmission, network device 120 receives another transmission of the data packet from terminal device 110-1 on the second set of CG resources. The other transmission is a transmission of a data packet following the initial transmission. In some embodiments, network device 120 may send an update indication to terminal device 110-1 to update the second set of CG resources. The update indication may be received via DC. The update indication may also be received via higher layer signaling, e.g., media access control element (MAC CE) or RRC signaling. Network device 120 may send a deactivation indication to terminal device 110-1 to deactivate the second set of CG resources. Similarly, the deactivation indication may be received via one of DCI, MAC CE, or RRC signaling. In other embodiments, network device 120 may send indication information to terminal device 110-1 indicating that the second set of CG resources remain active. The indication information may also be received via one of DCI, MAC CE, or RRC signaling. In some embodiments, the indication information further includes another mapping between the second set of CG resources and the synchronization signal block.
As noted above, the above description of method 200 and method 400 is merely a general description of embodiments. Specific example embodiments will be described below with reference to fig. 5 to 8.
According to some embodiments of the present disclosure, a terminal device receives a first CG resource set and a second CG resource set from a network device. The terminal device sends another transmission of the data packet using the second set of CG resources after sending the initial transmission of the data packet using the first set of CG resources. In this way, the effect of reducing the transmission delay of the uplink packet service of the terminal equipment under the condition that the detection overhead of the network equipment is relatively low is obtained. For example, fig. 5 illustrates an interaction signaling diagram of a particular communication process 500 according to the above scheme, where the first set of CG resources and the second set of CG resources are both type 1CG resources. As shown in fig. 5, communication process 500 involves terminal device 110-1 and network device 120. It is to be understood that the communication process shown in fig. 5 is exemplary only, and not limiting. Embodiments of the present disclosure may include interactive signaling not shown in fig. 5, or omit some of the signaling shown in fig. 5.
Network device 120 sends (5005) the first configuration to terminal device 110-1. The first configuration indicates a first set of CG resources for transmitting data. In some embodiments, network device 120 transmits the first configuration via RRC signaling when the terminal device 110-1 is in an RRC _ CONNECTED state. Alternatively, network device 120 may send the first configuration during a random access procedure for terminal device 110-1. In other embodiments, network device 120 may send the first configuration to terminal device 110-1 when terminal device 110-1 sends a Random Access SDT (RA-SDT). For example, in the four-step random access procedure, terminal device 110-1 transmits a preamble as a random access request, i.e., message 1 (message 1), to network device 120. Network device 120 sends a response to the random access request (i.e., message 2) to terminal device 110-1, which message 2 includes an uplink grant. Terminal device 110-1 sends an RRC connection request (i.e., message 3) to network device 120 based on the response. Message 3 includes packet data. Network device 120 may send an RRC connection setup message (i.e., message 4) to terminal device 110-1. Network device 120 may send the first configuration to terminal device 110-1 upon receiving message 3, which includes the packet data. In the two-step random access procedure, terminal device 110-1 transmits a preamble and packet data, i.e., message a (message a), to network device 120. Network device 120 sends a response to this message a (i.e., message B) to terminal device 110-1. Network device 120 may send the first configuration to terminal device 110-1 after receiving message a, which includes the packet data.
In some embodiments, the first configuration may comprise a resource configuration. Alternatively or additionally, the first configuration may also comprise a transmission parameter configuration. As an example, the first configuration may include one or more of: a period of the first CG resource, an open-loop power control parameter, a waveform, a redundancy version, a repetition number, a frequency hopping pattern, a resource allocation type, a number of hybrid automatic repeat procedures, a DMRS information parameter, an MCS table, a resource block group size, a time domain resource, a frequency domain resource, or an MCS. The first configuration may also include a CS-RNTI for the retransmission. Additionally, the first configuration may include a time domain parameter of a start symbol and an allocation length. In some embodiments, the first configuration may include one or more first CG resource sets. These multiple first CG resource sets may have the same or different periodicity.
In some embodiments, the first configuration may indicate a correspondence of the first CG resource set to the SSBs. As an example, as shown in FIG. 6, one SSB cycle includes four SSBs (i.e., SSB130-1, SSB130-2, SSB130-3, SSB 130-4). For example, CG resources for odd cycles correspond to SSB130-1 or SSB130-2, and CG resources for even cycles correspond to SSB130-3 or SSB130-4. As shown in FIG. 6, resource 310-1 may correspond to SSB130-1 or SSB130-2, resource 310-2 may correspond to SSB130-3 or SSB130-4, and resource 310-3 may correspond to SSB130-1 or SSB130-2. It is to be understood that the correspondence shown in fig. 6 is merely exemplary and not limiting.
In some embodiments, network device 120 sends (5005) the first configuration and the second configuration in the same signaling to terminal device 110-1. The second configuration indicates a second set of CG resources for transmitting data. The periodicity of the second set of CG resources is less than the periodicity of the first set of CG resources. The second configuration may include one or more of: a period of the second CG resource, an open loop power control parameter, a waveform, a redundancy version, a repetition number, a frequency hopping pattern, a resource allocation type, a number of hybrid automatic repeat requests, a demodulation reference information parameter, a modulation coding scheme table, a resource block group size, a time domain resource, a frequency domain resource, or a modulation coding scheme. Additionally, the second configuration may include time domain parameters including a start symbol and an allocation length. In some embodiments, the second configuration may include one or more second sets of CG resources. These multiple second CG resource sets may have the same or different periodicity.
In some embodiments, the second configuration includes an activation condition for activating the second set of CG resources. For example, the activation condition may be that the terminal device sends an initial transmission of a data packet using the first CG resource set and the initial transmission indicates that there is information for the data packet to be sent. In other embodiments, the activation condition may further include the terminal device transmitting a data packet during a random access procedure. Alternatively or additionally, the activation condition may also include the terminal device receiving feedback information for the data packet.
In some embodiments, terminal device 110-1 may enter the RRC _ INACTIVE state after receiving the first configuration. Alternatively, terminal device 110-1 may enter an RRC IDLE state. Network device 120 may detect whether there is a data transmission only at the first CG resource set when terminal device 110-1 enters the RRC _ INACTIVE state.
When there is uplink traffic arriving, terminal device 110-1 sends (5010) an initial transmission to network device 120 using the first set of CG resources. The initial transmission may indicate that there are packets to be sent. For example, the initial data may include a BSR to inform network device 120 that there is a subsequent data packet to transmit. As shown in fig. 6, at time 6010 there is a packet 610 to transmit. Terminal device 110-1 may send an initial transmission of data packet 610 on resource 310-2. In some implementations, terminal device 110-1 may select SSB130-3 or SSB130-4 and send the initial transmission of data packet 610 on a resource (e.g., resource 310-2) corresponding to SSB130-3 or SSB130-4. For example, terminal device 110-1 may transmit a portion of data packet 610 (e.g., 6101) on resource 310-2.
Network device 120 may send (5015) the feedback information to terminal device 110-1. If the feedback information is ACK, the initial transmission is indicated to be successful. If the feedback information is NACK, it indicates that the initial transmission failed. The feedback information may be transmitted at the L1 layer, i.e., the feedback information is transmitted through DCI. In other embodiments, the feedback information may be transmitted in higher layer signaling. For example, the feedback information may be transmitted in signaling of the MAC layer (such as MAC CE). Alternatively, the feedback information may be transmitted in signaling of the RRC layer.
In some implementations, the feedback information may include the second configuration. The content included in the second configuration is the same as the content in the embodiment where the first configuration and the second configuration are sent in the same signaling, and is not described herein again.
In other embodiments, the feedback information may also indicate a mapping between the second set of CG resources and the SSB. In some embodiments, the first set of synchronization signal blocks corresponding to the first CG resource set is the same as the second set of synchronization signal blocks corresponding to the second CG resource set. As shown in FIG. 7A, the first CG resource of an odd cycle corresponds to SSB130-1 or SSB130-2, and the first CG resource of an even cycle corresponds to SSB130-3 or SSB130-4. If terminal device 110-1 sends the initial transmission on resource 310-2, resource 320-1 corresponds to SSB130-3 or SSB130-4, resource 320-2 corresponds to SSB130-3 or SSB130-4, and resource 320-3 corresponds to SSB130-3 or SSB130-4. In other embodiments, the second set of synchronization information blocks is a subset of the first set of synchronization information blocks. In other words, SSBs may be distinguished by resources in the second CG resource set. As shown in FIG. 7B, the first CG resource of an odd cycle corresponds to SSB130-1 or SSB130-2, and the first CG resource of an even cycle corresponds to SSB130-3 or SSB130-4. Resource 320-1 corresponds to SSB130-3, resource 320-2 corresponds to SSB130-4, and resource 320-3 corresponds to SSB130-3. Therefore, when receiving, the network device can also receive data sent by the terminal device on different resources according to different SSB beams, which is beneficial to selecting a more appropriate receiving filter and improving the receiving performance of the network device. Network device 120 may send an indication to terminal device 110-1 as to which correspondence is used. In other words, network device 120 may instruct terminal device 110-1 to use the correspondence of resources to SSBs as shown in fig. 7A or fig. 7B. The indication may be transmitted at L1 layer, i.e., sent over DCI. In other embodiments, the indication may be transmitted in higher layer signaling. For example, the indication may be sent in signaling at the MAC layer (such as MAC CE). Alternatively, the indication may be sent in the signaling of the RRC layer. In this way, it is beneficial for more CG resources to correspond to the SSB selected by the terminal device, and not increase the detection overhead of the network device too much.
Returning to fig. 5, terminal device 110-1 may activate 5020 the second set of CG resources. As described above, the second configuration may include an activation condition. In some embodiments, the activation condition may be defined in a communication protocol. Terminal device 110-1 may activate the second CG resource set if the activation condition is satisfied. For example, when terminal device 110-1 utilizes a first set of CG resources to transmit an initial transmission of a data packet and the initial transmission indicates that there is information for the data packet to be transmitted, terminal device 110-1 may activate a second set of CG resources. In other embodiments, terminal device 110-1 may activate the second CG resource set at an initial transmission after terminal device 110-1 transmits the data packet in the random access procedure and the initial transmission indicates that there is information to be transmitted for the data packet. Alternatively or additionally, terminal device 110-1 may activate the second CG resource set after receiving the feedback information for the data packet and indicating in the feedback information that the terminal device activated the second set of configuration granted resources.
After the initial transmission, the end device 110-1 sends (5025) another transmission of the data packet to the network device 120 using the second set of CG resources. For example, as shown in FIG. 6, terminal device 110-1 may transmit another portion 6102 of the data packet on resource 320-1. In some embodiments, after the initial transmission, additional packets may arrive, such as packet 620. Terminal device 110-1 may transmit data packet 620 on resource 320-2 and/or resource 320-3.
Referring to fig. 7A, terminal device 110-1 sends an initial transmission on resource 310-2, and resource 310-2 corresponds to SSB130-3 or SSB130-4. In this case, terminal device 110-1 sends another transmission of the data packet at resource 320-1, which resource 320-1 also corresponds to SSB130-3 or SSB130-4.
Referring to fig. 7B, terminal device 110-1 sends an initial transmission on resource 310-2 and selects SSB130-3. In this case, terminal device 110-1 sends another transmission of the data packet on the resource to which SSB130-3 corresponds, e.g., on resource 320-1. In other embodiments, if terminal device 110-1 sends the initial transmission on resource 310-2, and SSB130-4 is selected. In this case, terminal device 110-1 sends another transmission of the data packet on the resource corresponding to SSB130-4, e.g., on resource 320-2.
In some embodiments, network device 120 may send (5030) an update indication to terminal device 110-1 to update the second set of CG resources. In some embodiments, network device 120 may send the update set before receiving another transmission of the data packet. Network device 120 may send the update set after receiving another transmission of the data packet, as shown in fig. 5. It is to be appreciated that the update indication can be sent at any suitable time after the transmission of the feedback information (5015). The update indication may be transmitted at the L1 layer, i.e., sent over DCI. In other embodiments, the update indication may be transmitted in higher layer signaling. For example, the update indication may be sent in signaling at the MAC layer (such as MAC CE). Alternatively, the update indication may be sent in the signaling of the RRC layer. For example, several bits in DCI or MAC CE may be used to indicate a periodic transition of the new second CG resource. Table 1 shows an example of the update indication. It is to be understood that the values shown in table 1 are exemplary only, and not limiting.
TABLE 1
Figure RE-GDA0003293561020000151
Terminal device 110-1 may update (5035) the second set of CG resources in accordance with the update indication. For example only, if the update indication includes "00," terminal device 110-1 may determine that the periodicity of the second set of CG resources is unchanged. If the update indication includes "01", terminal device 110-1 may determine that the period of the first set of second CG resource sets becomes 10 slots. For example, terminal device 110-1 may determine that period 3200 of CG resource set 320 becomes 10 slots. In other embodiments, terminal device 110-1 may determine that the periodicity of the second set of second CG resource sets is increased by 1 slot if the update indication comprises "10". For example, terminal device 110-1 may determine that the periodicity 3400 of CG resource set 340 is increased by 1 slot. In some embodiments, if the update indication includes "11," terminal device 110-1 may determine that the periodicity of the second set of second CG resource sets is reduced by 1 slot. For example, terminal device 110-1 may determine that the periodicity 3400 of CG resource set 340 is reduced by 1 slot.
In some embodiments, network device 120 may send (5040) a deactivation indication to terminal device 110-1 to deactivate the second set of CG resources. The deactivation indication may deactivate the one or more second CG resource sets. For example, the deactivation indication may indicate that CG resource set 320 is deactivated. Alternatively, the deactivation indication may indicate that CG resource set 340 is deactivated. The deactivation indication may also indicate that all CG resource sets are deactivated. It will be appreciated that the deactivation indication may be sent at any suitable time after another transmission (5025) of the data packet. The deactivation indication may be transmitted at the L1 layer, i.e., sent over DCI. In other embodiments, the deactivation indication may be transmitted in higher layer signaling. For example, the deactivation indication may be sent in signaling at the MAC layer (such as MAC CE). Alternatively, the deactivation indication may be sent in signaling at the RRC layer.
Terminal device 110-1 may send 5045 a buffer status report to network device 120. Alternatively, terminal device 110-1 may send an RRC message (e.g., an RRC release message) to inform network device 120 that it will stop sending data packets. In this case, in some embodiments, terminal device 110-1 may cease using the second set of CG resources by default. Terminal device 110-1 may transmit subsequently arriving uplink data using subsequent CG resources in the first set of CG resources. It will be appreciated that the transmission of the buffer status report (5045) is not in sequential relationship with the transmission of the activation indication (5040) and the transmission of the indication information (5045). In other words, the buffer status report may be sent before or after the activation indication and the indication information. In some embodiments, the buffer status report may also be sent in the initial transmission of the data packet (5010).
In some embodiments, network device 120 may send 5050 an indication to terminal device 110-1 that the second set of CG resources remains active. After receiving the indication information, terminal device 110-1 determines that the second CG resource set remains activated. In some embodiments, terminal device 110-1 may utilize the second set of CG resources to send an initial transmission of subsequently arriving uplink data. Alternatively, terminal device 110-1 may utilize a second set of CG resources to send subsequent transmissions of subsequently arriving uplink data. In other implementations, terminal device 110-1 may utilize the second set of CG resources for retransmission of uplink data. In other embodiments, the indication information may also indicate another mapping between the second set of CG resources and the SSB. In some embodiments, the first set of synchronization signal blocks corresponding to the first set of CG resources is the same as the second set of synchronization signal blocks corresponding to the second set of CG resources. In other embodiments, the second set of synchronization information blocks is a subset of the first set of synchronization information blocks. In other words, SSBs may be distinguished by resources in the second CG set of resources. The other mapping may be the same as or different from the mapping sent in the feedback information.
Fig. 8 shows an interaction signaling diagram of a specific communication procedure 800 according to the above scheme, wherein the first CG resource set is a type 1CG resource and the second CG resource set is a type2CG resource. As shown in fig. 8, communication process 800 involves terminal device 110-1 and network device 120. It is to be understood that the communication process shown in fig. 8 is exemplary only, and not limiting. Embodiments of the present disclosure may include interactive signaling not shown in fig. 8, or omit some of the signaling shown in fig. 8. According to the embodiment shown in fig. 8, the technical effect of reducing the uplink packet service transmission delay of the terminal device under the condition that the detection overhead of the network device is relatively low can be obtained, and the technical effect of flexibly configuring/changing the parameters of the CG resources by the network device can be obtained.
Network device 120 sends (8005) the first configuration to terminal device 110-1. The first configuration indicates a first set of CG resources for transmitting data. The transmission of the first configuration (8005) is similar to the transmission of the first configuration (5005) described with reference to fig. 5 and is not described herein again. The content and the first CG resource set included in the first configuration are similar to those included in the first configuration described with reference to fig. 5, and are not described herein again.
Network device 120 sends (8005) the first configuration and the second configuration in the same signaling to terminal device 110-1. The second configuration indicates a second set of CG resources for transmitting data. The periodicity of the second set of CG resources is less than the periodicity of the first set of CG resources. The parameters of the second configuration include: a period of the second CG resource, an open loop power control parameter, a waveform, a redundancy version, a repetition number, a frequency hopping pattern, a resource allocation type, a number of hybrid automatic repeat request processes, a demodulation reference information parameter, a modulation coding scheme table, or a resource block group size, wherein a part of the second configured parameter is transmitted in RRC signaling, and another part is transmitted in DCI activating a type2CG resource. For example, the other part of the parameters may be transmitted in the CS-RNTI scrambled DCI.
In some embodiments, terminal device 110-1 may enter the RRC _ INACTIVE state after receiving the first configuration. Alternatively, terminal device 110-1 may enter the RRC _ IDLE state. Network device 120 may detect whether there is a data transmission only at the first CG resource set when terminal device 110-1 enters the RRC _ INACTIVE state.
When there is an upstream traffic arriving, the terminal device 110-1 sends (8010) an initial transmission to the network device 120 using the first CG resource set. The initial transmission may indicate that there are data packets to be sent. The transmission of the initial transmission (8010) is similar to the transmission of the initial transmission (5010) described with reference to fig. 5 and will not be described in detail here.
Network device 120 may send 8015 the feedback information to terminal device 110-1. If the feedback information is ACK, the initial transmission is indicated to be successful. If the feedback information is NACK, it indicates that the initial transmission failed. The feedback information may be transmitted at the L1 layer, i.e., the feedback information is transmitted through DCI. In other embodiments, the feedback information may be transmitted in higher layer signaling. For example, the feedback information may be transmitted in signaling of the MAC layer (such as MAC CE). Alternatively, the feedback information may be transmitted in signaling of the RRC layer. In other embodiments, the feedback information may also indicate a mapping between the second set of CG resources and the SSB. In some embodiments, the first set of synchronization signal blocks corresponding to the first CG resource set is the same as the second set of synchronization signal blocks corresponding to the second CG resource set. In other embodiments, the second set of synchronization information blocks is a subset of the first set of synchronization information blocks. In other words, SSBs may be distinguished by resources in the second CG set of resources. Therefore, when receiving, the network device can also receive data sent by the terminal device on different resources according to different SSB beams, which is beneficial to selecting a more appropriate receiving filter and improving the receiving performance of the network device. Network device 120 may send an indication to terminal device 110-1 as to which correspondence is used. The indication may be transmitted at the L1 layer, i.e., sent over DCI. In other embodiments, the indication may be transmitted in higher layer signaling. For example, the indication may be sent in signaling at the MAC layer (such as MAC CE). Alternatively, the indication may be sent in the signaling of the RRC layer. In this way, it is beneficial for more CG resources to correspond to the SSB selected by the terminal device, and the detection overhead of the network device is not excessively increased.
Network device 120 sends 8020 an activation indication to terminal device 110-1 for activating the second set of CG resources. For example, network device 120 may send the activation indication when terminal device 110-1 sends an initial transmission of a data packet using a first set of CG resources and the initial transmission indicates that there is information for the data packet to send. In other embodiments, network device 120 sends the activation indication after terminal device 110-1 sends the data packet in the random access procedure. Alternatively or additionally, network device 120 sends the activation indication after sending feedback information for the data packet. The activation indication may be transmitted at the L1 layer, i.e., sent over DCI. In other embodiments, the activation indication may be transmitted in higher layer signaling. For example, the activation indication may be sent in signaling at the MAC layer (such as MAC CE). Alternatively, the activation indication may be sent in signaling at the RRC layer. Terminal device 110-1 activates 8025 the second set of CG resources in accordance with the activation indication. In some embodiments, the activation indication may include one or more of the following parameters: time domain resources, frequency domain resources, DMRS, or MCS.
After the initial transmission, terminal device 110-1 sends (8030) another transmission of the data packet to network device 120 using the second set of CG resources. The further transmission of the data packet (8030) is similar to the further transmission of the data packet (5025) described with reference to fig. 5 and will not be described again here.
In some embodiments, network device 120 may send (8040) an update indication to terminal device 110-1 to update the second set of CG resources. The update indication and sending (8040) is similar to the update and sending (5035) described with reference to FIG. 5 and is not further described herein. Terminal device 110-1 may update (8040) the second set of CG resources according to the update indication. The terminal device 110-1 performs the update in a manner similar to the update (5035) described with reference to fig. 5, and is not described again here.
In some embodiments, network device 120 may send (8045) a deactivation indication to terminal device 110-1 to deactivate the second set of CG resources. The content included in the deactivation indication and the transmission of the deactivation indication are similar to the transmission (5040) of the deactivation indication and the deactivation indication described with reference to fig. 5, and are not described again here.
Terminal device 110-1 may send (8050) a buffer status report to network device 120. The information included in the buffer status report and the transmission (8050) thereof are similar to the information included in the buffer status report and the transmission (5045) thereof described with reference to fig. 5, and are not described herein again. It is to be understood that the sending of the buffer status report (8050) is not in sequential relation to the sending of the activation indication (8045) and the sending of the indication information (8055). In other words, the buffer status report may be sent before or after the activation indication and the indication information. In some embodiments, the buffer status report may also be sent in the initial transmission of the packet (8010).
In some embodiments, network device 120 may send 8055 indication information to terminal device 110-1 indicating that the second set of CG resources remains active. The information included in the indication information and the transmission mode thereof are similar to the information included in the indication information and the transmission mode thereof (5050) described with reference to fig. 5, and are not described again.
