[0004] In order to support direct communication between user equipment (UE), a sidelink communication mode is introduced. In the SL communication mode, the interface for communication between the transmitting UE and the receiving UE is PC-5.

[0005] In the related art, the transmitting UE can directly or indirectly provide configurations to the receiving UE so that the receiving UE can communicate based on the configurations provided by the transmitting UE. If the receiving UE can use all the configurations provided by the transmitting UE, a message that the configurations are effective will be replied to the transmitting UE. However, if the receiving UE cannot use some of the configurations, a message that the configurations failed will be replied to the transmitting UE. This current configuration method is not conducive to the configuration efficiency of the receiving UE. Summary of the invention

The user equipment 110 can be an Internet of Things user equipment, such as a sensor device, a mobile phone (or a "cellular" phone), and a computer with an Internet of Things user equipment. For example, it can be a fixed, portable, pocket-sized, handheld, computer-built-in or vehicle-mounted device. For example, a station (STA), a subscriber unit, a subscriber station, a mobile station, a mobile station, a remote station, an access point, a remote user device, an access terminal, a user terminal, a user agent, a user device, or a user equipment. Alternatively, the user equipment 110 can also be a device of an unmanned aerial vehicle.

Alternatively, the wireless communication system may be a next generation system of the 5G system. The access network in the 5G system may be referred to as a new generation radio access network (NG-RAN).

Alternatively, the base station 120 can also be a base station (gNB) adopting a centralized distributed architecture in the 5G system.

[0157] In order to facilitate the understanding of those skilled in the art, the embodiments of the present disclosure list multiple implementation methods to clearly illustrate the technical solutions of the embodiments of the present disclosure. Of course, those skilled in the art can understand that the multiple embodiments provided by the embodiments of the present disclosure can be executed separately, or can be executed together with the methods of other embodiments of the embodiments of the present disclosure, or can be executed together with some methods in other related technologies separately or in combination; the embodiments of the present disclosure do not limit this.

[0158] In order to better understand the technical solution disclosed in the embodiment of the present disclosure, the direct link SL configuration of the user equipment (UE) is partially described below:

[0159] Sidelink (SL) technology is a near-field communication technology in which UEs directly connect information through wireless interfaces between each other. Sometimes SL can also be called a side link or a secondary link. In the SL communication mode, the interface for communication between the transmitting UE and the receiving UE is PC-5. Three transmission modes are supported on SL, unicast, multicast and broadcast. It can be understood that if a point-to-point connection is adopted between the transmitting UE and the receiving UE, then the transmitting UE and the receiving UE communicate on SL in a unicast transmission mode. It can be understood that in a unicast connection, each UE on the receiving end corresponds to a destination identifier. If the receiving UE accesses by accessing the multicast address provided by the transmitting UE, then the transmitting UE and the receiving UE communicate on SL in a multicast transmission mode. It can be understood that in a multicast connection, each UE on the receiving end can belong to one or more groups, and each group corresponds to a destination identifier. If the receiving UE accesses the broadcast address provided by the sending UE, the sending UE and the receiving UE communicate on the SL in a broadcast transmission manner. It can be understood that in a broadcast connection, all UEs on the receiving end correspond to at least one destination identifier.

[0160] The transmitting UE in the SL can configure the communication configuration on the SL for the receiving UE in the SL according to the network configuration or service characteristics, so that the receiving UE can communicate in the network according to the communication configuration. The communication configuration here is the SL configuration described in the embodiment of the present disclosure.

[0161] In some embodiments, the transmitting UE may send SL control information on a physical sidelink control channel (PSCCH), wherein the SL control information may carry SL configuration for the receiving UE.

[0162] It should be noted that Radio Resource Control (RRC) processes the third layer information between the UE and the control plane of the radio access network. RRC is mainly used to establish a signaling link between the UE and the radio access network and allocate and manage radio resources. In order for the UE to communicate with the radio access network, it is necessary to first establish an RRC link before the signaling of the non-access layer can be transmitted. At present, there are two ways to release the RRC connection. One is that the network sends a message to release the RRC connection, and the terminal can release the RRC connection after receiving the message. The other is that the base station configures an inactive timer for the UE. If the inactive timer times out, the UE automatically releases the RRC connection. During the duration configured by the inactive timer, if the inactive timer is not triggered to restart, the inactive timer times out. In other words, if no data or control signaling is sent for a period of time, the UE will automatically release the RRC connection.

[0163] See also Figure 2 and Figure 3 , the transmitting UE sends a reconfiguration SL message to the receiving UE, and the reconfiguration SL message carries the SL configuration for the receiving UE. In some possible implementations, the reconfiguration SL message may be an RRCReconfigurationSidelink message, wherein the RRCReconfigurationSidelink message carries the SL configuration for the receiving UE. The following description takes the RRCReconfigurationSidelink message as an example. Of course, the reconfiguration SL message may be other messages, which will not be repeated here. In the related art, after receiving the RRC reconfiguration SL message, if the SL configuration carried in the RRCReconfigurationSidelink message can be used, the receiving UE replies with a message that the configuration of the transmitting UE is effective, wherein the message that the configuration is effective may be, for example, an RRCReconfigurationCompleteSidelink message, and the inactive timer is stopped; if the SL configuration carried in the RRC reconfiguration SL message cannot be used, the sending UE is replied with a message that the configuration fails, wherein the message that the UE configuration fails may be, for example, an RRCReconfigurationFailureSidelink, and the inactive timer is stopped.

[0164] That is to say, in the related technology, the receiving UE can only reply that the configuration is effective or the configuration fails in response to the SL configuration provided by the transmitting UE. When the receiving UE replies to the transmitting UE that the configuration fails, the transmitting UE cannot know exactly which SL configurations caused the configuration failure, and thus cannot quickly provide the receiving UE with a usable SL configuration, affecting the configuration efficiency of the receiving UE.

[0165] Based on this, see Figure 4 ,like Figure 4 As shown, an embodiment of the present disclosure provides a communication configuration method, which is performed by a first user equipment UE, including:

[0166] Step S41: In response to at least part of the direct link SL configuration provided by the second UE being unusable, sending indication information to the second UE via the SL, wherein the indication information at least indicates: one or more SL configurations not used by the first UE, or one or more SL configurations used by the first UE.

[0167] The UE here can be various mobile terminals or fixed terminals. For example, the UE can be, but is not limited to, a mobile phone, a computer, a server, a wearable device, a game control platform, or a multimedia device.

[0168] The first UE here may be a receiving UE that receives the SL configuration, and the second UE here may be a sending UE that provides the SL configuration as mentioned above.

[0169] Here, after the first UE and the second UE establish a connection (for example, a unicast connection), the second UE may provide a communication configuration to the first UE so that the first UE can communicate based on the communication configuration.

[0170] In some embodiments, the SL configuration provided by the second UE to the first UE is sent to the second UE by the base station of the second UE, and then provided to the first UE by the second UE.

[0171] In some other embodiments, the second UE may provide its own SL configuration to the first UE so as to be able to communicate with the first UE based on the same SL configuration. Of course, in other embodiments, the second UE may provide the SL configuration to the first UE based on a request from the first UE to the second UE.

[0172] Here, the case where the first UE does not use the SL configuration includes at least one of the following:

[0173] The SL configuration received by the first UE conflicts with the SL configuration currently used by the first UE or other configurations except the SL configuration;

[0174] The SL configuration received by the first UE is wrong;

[0175] The first UE rejects the received SL configuration;

[0176] The base station of the first UE rejects the received configuration.

[0177] Here, the SL configuration received by the first UE conflicts with the SL configuration currently used by the first UE, which can be understood as the SL resources indicated by the SL configuration received by the first UE do not match the SL resources indicated by the SL configuration currently used by the first UE, or do not match the resources indicated by other configurations currently used by the first UE except the SL configuration. Exemplarily, the link configuration in the SL configuration received by the first UE does not match the available links in the SL configuration currently used by the first UE, or does not match the available links in other configurations currently used by the first UE except the SL configuration. For example, the SL configuration received by the first UE is configured as link A, while the SL configuration currently used by the first UE or other configurations except the SL configuration indicates that link A cannot communicate, that is, the current communication configuration of the first UE indicates that there is no link A in the available links. Therefore, the SL configuration received by the first UE conflicts with the communication configuration currently used by the first UE.

[0178] Here, the SL configuration error received by the first UE can be understood as the SL configuration received by the first UE has errors. Exemplarily, the SL configuration received by the first UE has errors such as missing data or data corruption. Exemplarily, during the transmission between the second UE and the first UE, the message carrying the SL configuration suffers data corruption due to the influence of transmission quality, etc., resulting in an SL configuration error; or, during the process of the base station providing the message to the second UE and instructing the second UE to provide the message to the first UE, the message carrying the SL configuration suffers data corruption during the transmission between the base station and the second UE, resulting in an SL configuration error.

[0179] Here, the first UE rejects the received SL configuration, which may include: the first UE rejects or discards the received SL configuration. In some cases, if the first UE is in a connected state with other UEs, the first UE cannot apply the SL configuration because all communication resources of the first UE are occupied. In some possible implementations, the first UE rejects the received SL configuration. Of course, there are also some cases where the first UE itself rejects other configurations except the configuration sent by a specific UE. The specific UE here refers to a UE that is pre-bound and connected to the first UE.

[0180] Here, the base station of the first UE rejects the received SL configuration, which may include: the base station of the first UE rejects or discards the received SL configuration. It can be understood that, when the first UE needs to communicate with other UEs through the base station, if the base station of the first UE acts as the scheduling mechanism of the first UE to decide who the first UE can communicate with and who it cannot communicate with. The base station of the first UE rejects the received configuration, which may also be similar to the first UE rejecting the received SL configuration. In some cases, if the base station of the first UE is in a connected state, the first UE may send the SL configuration to the base station connected to the first UE so that the base station determines whether it can be used according to the SL configuration. For example, if the SL configuration sent by the second UE includes a DRX configuration, and the period of the DRX configuration happens to conflict with the period used by the base station to schedule the first UE for transmission, the base station may notify the first UE to reject the SL configuration. That is, if the SL configuration conflicts with the configuration of the base station of the first UE, the base station of the first UE rejects the SL configuration. Of course, there is another possible implementation method: because the base station of the first UE only accepts the SL configuration sent by a specific UE; wherein the specific UE refers to a UE that is pre-bound and connected to the base station of the first UE. In some possible implementations, the base station may send a message (e.g., a failure indication) rejecting the SL configuration to the first UE, which is then sent by the first UE to the second UE. Of course, it may also be implemented in other ways, and the embodiments of the present disclosure do not limit this. In the embodiments of the present disclosure, the first UE determines whether to use the SL configuration and the base station of the first UE determines whether to use the SL configuration, which may be a parallel step or a serial step. That is, in some possible implementations, after receiving the SL configuration, the first UE sends the SL configuration to the base station only when the first UE determines that the SL configuration is available; in other possible implementations, after receiving the SL configuration, the first UE directly sends the SL configuration to the base station, and the first UE does not judge whether the SL configuration is available. In one possible application scenario, when the first UE is in a connected state, the base station may determine which SL configurations are available or which SL configurations are not available. In another possible application scenario, when the first UE is in a non-connected state (e.g., when the UE is in an inactive state or an idle state), the first UE may determine which SL configurations are available or which SL configurations are not available.

[0181] The indication information here at least indicates: one or more SL configurations not used by the first UE, or one or more SL configurations used by the first UE. In some exemplary embodiments, sending the indication information to the second UE via the SL may include: sending a failure indication including an identifier of an unused SL configuration to the second UE via the SL, or sending a success indication including an identifier of a used SL configuration to the second UE via the SL.

[0182] It should be noted that the SL configuration provided by the second UE may be multiple sets of SL configurations, wherein different SL configurations have different identifiers.

[0183] Exemplarily, the identifier of the SL configuration may be set in a specific field in a message carrying the SL configuration, for example, the identifier of the SL configuration may be set in the header of the message carrying the SL configuration. The first UE may inform the second UE of one or more SL configurations that cannot be used by sending a failure indication including the identifier of an unused SL configuration to the second UE; or, the first UE may inform the second UE of one or more SL configurations that can be used by sending an identifier including a usable SL configuration to the second UE. Similarly, after receiving the failure indication including the identifier of an unused SL configuration, the second UE may parse out the identifier of the unused SL configuration from the failure indication, thereby knowing the SL configuration that the first UE cannot use; or, after receiving the success indication including the identifier of the used SL configuration, the second UE may parse out the identifier of the used SL configuration from the success indication, thereby knowing the SL configuration that the first UE can use.

[0184] Compared with the related art, in which the second UE cannot know for sure the SL configuration that the first UE cannot use, since the first UE sends a failure indication to the second UE to indicate the SL configuration that the first UE does not use, or the first UE sends a success indication to the second UE to indicate the SL configuration used by the first UE, the time for reconfiguring all SL configurations due to the second UE being unable to know one or more sets of SL configurations that the first UE cannot use can be reduced, and the waste of communication resources caused by reconfiguring one or more sets of SL configurations that can be used due to the second UE being unable to know that the first UE can use one or more sets of SL configurations can be reduced, thereby improving the SL configuration efficiency of the first UE and improving the communication performance of the first UE.

[0185] In some exemplary embodiments, the SL configuration includes: a first configuration, wherein the first configuration includes a first discontinuous reception (DRX) configuration of the SL.

[0186] In some embodiments, in order to save power consumption of UE, DRX can be configured for UE. When UE is in connected state, DRX configuration may include at least one of the following parameters: inactivity timer, wake-up timer, cycle and starting offset, uplink hybrid automatic repeat request Round-TripTime (HARQ RTT) timer, downlink HARQ RTT timer, uplink retransmission timer, downlink retransmission timer, etc. Of course, other parameters may also be included. Among them, the cycle and starting offset may be used to determine the periodic starting time point of the wake-up timer. Whenever UE receives downlink control information (Downlink ContorlInformation, DCI) carrying its own cell radio network temporary identifier (Cell-Radio Network Temporary Identifier, C-RNTI) on the physical downlink control channel (Physical Downlink Control Channel, PDCCH), the inactivity timer will be started. UE monitors PDCCH channel only during wake-up period, and UE may not monitor PDCCH channel at other times, thereby saving power consumption. When the UE receives a MAC protocol unit (ProtocolData Unit, PDU), it sends feedback to the base station and starts the downlink HARQ RTT timer of the corresponding HARQ process to time out. When the uplink HARQ RTT timer of the downlink HARQ process times out, the downlink retransmission timer is started. After the UE sends a PUSCH transmission, the UE starts the uplink HARQ RTT timer of the corresponding HARQ process. When the uplink HARQ RTT timer times out, the uplink retransmission timer is started. The wake-up time includes the running time of the wake-up timer, the inactivity timer, the uplink retransmission timer, and the downlink retransmission timer.

[0187] In this way, the UE can start the timer of the corresponding function according to the DRX configuration to achieve time control of more important functions such as wake-up, sleep and retransmission.

[0188] In some embodiments, in order to save power consumption of UEs on the SL link, the DRX configuration of the SL. For broadcast and multicast connections, the DRX configuration of the SL of the first UE can be determined according to the service type, while for unicast connections, the DRX configuration of the SL of the first UE can be configured by the second UE or the base station of the second UE.

[0189] It can be understood that, based on the DRX configuration of SL for the first UE, the first UE can monitor the PSCCH channel only during the activation time, thereby achieving the purpose of energy saving.

[0190] In some embodiments, in order to prevent data sent by the second UE from being lost, the second UE sends SL data to the first UE only within the activation time of the first UE.

[0191] It should be added that, in some embodiments, when configuring DRX of SL for the first UE, it is necessary to consider the DRX alignment of SL before any two or three connections among the multicast connection, unicast connection and broadcast connection of the first UE, and it is also necessary to consider aligning the SL of the first UE with the DRX on the Uu interface so that the activation time coincides, thereby ensuring the energy saving effect of the first UE.

[0192] The first configuration here is the DRX configuration on the SL provided by the second UE to the first UE.

[0193] In some exemplary embodiments, the SL configuration includes: a second configuration, wherein the second configuration includes: other configurations of the SL except the DRX configuration.

[0194] Here, the first configuration is different from the second configuration.

[0195] In all the embodiments of the present disclosure, the SL configuration may be exemplarily a SL discontinuous reception (DRX) configuration. In the embodiments of the present disclosure, since the SL connection may include any one of the following: unicast, multicast, and broadcast. Therefore, in some embodiments of the present disclosure, when the UE has more than two SL connections, the DRX configurations of two or more SL connections may be aligned so that the UE can adjust the SL parameters of different connections to provide efficiency. For example, if the DRX configurations of the UE can be adapted so that the UE can reduce the number of wake-ups and / or the length of wake-up time to achieve energy saving. In other embodiments of the present disclosure, other parameters of the UE may also be coordinated with each other to achieve the purpose of improving transmission efficiency and / or energy saving, and the embodiments of the present disclosure are not limited to this. That is, the SL configuration may include a DRX configuration, or the SL configuration may not include a DRX configuration, but include any one or more of the following:

[0196] Data transmission configuration;

[0197] SL bearer configuration;

[0198] Other SL configurations except DRX configuration.

[0199] Here, the data transmission configuration may include but is not limited to: a data transmission channel, a data transmission method, and a data transmission timing.

[0200] Here, the SL bearer configuration may include but is not limited to: bearer identification, SDAP (Service Data Adapation Protocol) configuration, PDCP (Packet Data Convergence Protocol) configuration, RLC (Radio Link Control) configuration, logical channel configuration, mirror QoS indication, and QoS parameters. Among them, the SDAP configuration includes at least one of the following: NULL, default bearer indication, Qos flow list mapped to the bearer, and whether the SDAP header is included. The PDCP configuration includes at least one of the following: packet discard timer, PDCP sequence number length, header compression, and reordering timer. The RLC configuration includes at least one of the following: non-deterministic mode or confirmation mode, polling-related configuration in confirmation mode, maximum number of retransmissions in confirmation mode, and whether out-of-order delivery is supported. The logical channel configuration includes at least one of the following: logical channel identification, logical channel priority, priority guarantee ratio, bucket size duration, subcarrier spacing, associated SL bandwidth part index, and associated carrier indication. The QoS parameters include at least one of the following: 5QI, allocation reservation priority, UE PC5 interface maximum aggregate bit rate UE-PC5-MABR, PC5 guaranteed flow ratio rate GFBR, PC5 maximum ratio rate MFBR. The PC5 mirror QoS indication can be used to indicate at least one of the following: priority, packet delay, packet error rate, reliability, and resource type.

[0201] Here, other SL configurations except DRX configuration may be SL configurations specified in the R16 5G standard, and the SL configurations specified in the R16 5G standard may include but are not limited to: SL resource configuration, SL feedback configuration and SL retransmission configuration, etc. Among them, SL resource configuration is used to configure the SL resource pool for the UE, and the SL feedback configuration includes at least one of the following: the content of SL feedback, the type of SL feedback, the period of SL feedback and the mapping method of SL feedback ratio. SL retransmission configuration includes at least one of the following: SL retransmission mode, SL transmission reliability information, medium access control MAC retransmission configuration information, SL feedback or transmission or retransmission resources, parameter configuration mapped to SL logical channel or bearer, or frame length information of transmission time interval mapped to SL logical signal or bearer, etc.

[0202] In this way, the configurations in the SL configuration except the DRX configuration can be used to provide communication configurations for the UE when performing cellular communication.

[0203] That is, the second configuration here may be provided by the second UE to the first UE, and can be used for the first UE to perform cellular communication other than DRX based on the second configuration.

[0204] In this embodiment, the SL configuration provided by the second UE includes at least: a first configuration and / or a second configuration, so that the first UE can communicate based on the provided SL configuration.

[0205] like Figure 5 As shown, an embodiment of the present disclosure provides a communication configuration method, which is performed by a first UE. The method may include:

[0206] Step S411: Sending a first indication to the second UE through the SL, where the first indication is used to indicate that one or more DRX configurations in the first configuration are unavailable;

[0207] or

[0208] Step S413: Send a second indication to the second UE via the SL, where the second indication is used to indicate that one or more DRX configurations in the first configuration are available.

[0209] In some embodiments, if the second UE receives the first indication, it indicates that the first UE cannot use the first configuration. In other embodiments, if the second UE receives the second indication, it indicates that the first UE can use the first configuration.

[0210] It should be noted that the above step numbers are only for distinguishing the steps and do not represent the execution order or combination of the steps.

[0211] In the embodiment of the present disclosure, if the second UE receives the first indication, it indicates that at least one or more sets of DRX configurations of the first configuration in the SL configuration provided by the second UE cannot be used. For example, please refer to Figure 3 The first indication here can be carried in the feedback message of the RRC reconfiguration SL message, for example, carried in the configuration failure message, and the configuration failure message here can be, for example, an RRCReconfigurationFailureSidelink message.

[0212] If the second UE receives the second indication, it indicates that at least one or more sets of DRX configurations of the first configuration in the SL configuration provided by the second UE can be used. For example, please refer to Figure 2 The second indication here can be carried in the feedback message in the RRC reconfiguration SL message, for example, carried in the configuration effectiveness message, and the configuration effectiveness message here can be, for example, the RRCReconfigurationCompleteSidelink message.

[0213] In the embodiment of the present disclosure, the second UE can learn the unusable SL configuration through the received first indication, and perform subsequent processing based on the unusable SL configuration. Exemplarily, targeted reconfiguration processing can be performed based on the unusable SL configuration. For example, the second UE can learn that the unusable SL configuration is the first configuration through the received first indication, and reconfigure the first configuration based on the first indication, thereby improving the configuration efficiency of the first UE. Alternatively, the second UE can learn the usable SL configuration through the received second indication, and perform subsequent processing based on the usable SL configuration. Exemplarily, other configurations other than the usable SL configuration can be reconfigured based on the usable SL configuration. For example, the second UE can reconfigure configurations other than the first configuration based on the second indication. In some possible implementations, the second configuration is reconfigured to improve the configuration efficiency of the first UE.

[0214] like Figure 6 As shown, an embodiment of the present disclosure provides a communication configuration method, which is performed by a first UE. The method may include:

[0215] Step S412: Send a first indication to the second UE through the SL, where the first indication is used to indicate that one or more SL configurations in the second configuration are available;

[0216] or

[0217] Step S414: Send a second indication to the second UE via the SL, where the second indication is used to indicate that one or more sets of SL configurations in the second configuration are unavailable.

[0218] It should be noted that the above step numbers are only for distinguishing the steps and do not represent the execution order or combination of the steps.

[0219] In the embodiment of the present disclosure, if the second UE receives the first indication, it indicates that at least one or more sets of SL configurations of the second configuration in the SL configuration provided by the second UE cannot be used. For example, please refer to Figure 3 The first indication here can be carried in the feedback message of the RRC reconfiguration SL message, for example, carried in the configuration failure message, and the configuration failure message here can be, for example, an RRCReconfigurationFailureSidelink message.

[0220] If the second UE receives the second indication, it indicates that at least one or more sets of SL configurations of the second configuration in the SL configuration provided by the second UE can be used. For example, please refer to Figure 2The second indication here can be carried in the feedback message in the RRC reconfiguration SL message, for example, carried in the configuration effectiveness message, and the configuration effectiveness message here can be, for example, the RRCReconfigurationCompleteSidelink message.

[0221] In the embodiment of the present disclosure, the second UE can learn that the SL configuration that cannot be used is a received first indication, and perform subsequent processing based on the SL configuration that cannot be used. Exemplarily, targeted reconfiguration processing can be performed based on the SL configuration that cannot be used. For example, the second UE can learn that the SL configuration that can use the function is a second configuration by receiving the first indication, and then reconfigure the configuration other than the second configuration. In some possible implementations, the first configuration is reconfigured to improve the configuration efficiency of the first UE. Alternatively, the second UE can learn that the SL configuration that cannot be used is a second configuration by receiving the second indication, and perform subsequent processing based on the SL configuration that cannot be used. In some possible implementations, the second configuration is reconfigured to improve the configuration efficiency of the first UE.

[0222] Please refer to Figure 5 and Figure 6 , an embodiment of the present disclosure provides a communication configuration method, which is performed by a first UE, wherein step S411 and step S412 can be implemented together; and / or, step S413 and step S414 can be implemented together.

[0223] It can be understood that, when one or more DRX configurations for the first configuration of the first UE are unavailable, but one or more SL configurations for the second configuration are available, the first UE can send a first indication to the second UE via SL. The first indication here can be used to indicate that one or more DRX configurations in the first configuration are unavailable, and one or more SL configurations in the second configuration are available.

[0224] It can be understood that, when one or more sets of DRX configurations for the first configuration are available for the first UE, but one or more sets of SL configurations for the second configuration are unavailable, the first UE can send a second indication to the second UE via SL. The second indication here can be used to indicate that one or more sets of DRX configurations in the first configuration are available, and one or more sets of SL configurations in the second configuration are unavailable.

[0225] In some exemplary embodiments, the first indication may include:

[0226] A first configuration request indication, wherein the first configuration request indication is used to: indicate a request for the second UE to send a new SL DRX configuration.

[0227] In some embodiments, the DRX configuration of the new SL may be the DRX configuration of the SL recommended for use by the first UE, or the DRX configuration of the SL recommended for use by the base station of the first UE. In other embodiments, the DRX configuration of the new SL may be the DRX configuration of the SL determined by the communication protocol of the first UE and adapted to the current communication resources of the first UE.

[0228] In the embodiment of the present disclosure, the first configuration request indication may implicitly indicate that the first configuration cannot be used in the SL configuration.

[0229] Here, the new SL DRX configuration may be the SL DRX configuration required to satisfy the activation time overlap of the first UE in various situations.

[0230] Please refer to Figure 2 The first configuration request indication here may be carried in a configuration effective message. Exemplarily, the configuration effective message may be an RRCReconfigurationCompleteSidelink message.

[0231] In some exemplary embodiments, the second indication includes:

[0232] A second configuration request indication, wherein the second configuration request indication is used to indicate a request for the second UE to send other configurations of a new SL except for the DRX configuration.

[0233] In some embodiments, the configuration other than the DRX configuration of the new SL may be the configuration other than the DRX configuration of the SL recommended for use by the first UE. In other embodiments, the DRX configuration of the new SL may be the configuration other than the DRX configuration of the SL applicable to the current communication resources of the first UE determined by the communication protocol of the first UE.

[0234] In the embodiment of the present disclosure, the second configuration request indication may implicitly indicate that the second configuration cannot be used in the SL configuration.

[0235] Please refer to Figure 2 The second configuration request indication here may be carried in a configuration effective message. Exemplarily, the configuration effective message may be an RRCReconfigurationCompleteSidelink message.

[0236] The present disclosure provides a communication configuration method, which is performed by a first UE. The method may include at least one of the following:

[0237] In response to the first UE determining that the DRX configuration in the SL configuration is unavailable, a first configuration is determined, wherein the default first configuration may be: the DRX configuration determined by the first UE according to the communication protocol, or the current DRX configuration of the first UE, or the default DRX configuration of the first UE.

[0238] In a possible implementation, the DRX configuration determined by the first UE according to the communication protocol may be the DRX configuration determined by the communication protocol used by the first UE before receiving the SL configuration provided by the second UE. The current DRX configuration of the first UE may be the DRX currently being used by the first UE. The default DRX configuration of the first UE may be a default DRX configuration pre-set for the first UE, and the default DRX configuration is different from the DRX configuration provided by the second UE. In a possible implementation, the default DRX configuration may be the current DRX configuration or may not be the current DRX configuration. When the DRX configuration in the SL configuration received by the first UE provided by the second UE is unavailable, the first UE may change from the currently used DRX configuration to the default DRX configuration.

[0239] In a possible implementation, the first UE may determine to use the default first configuration before, when, or after sending the first indication. It should be noted that since the first indication is used to indicate that one or more sets of DRX configurations in the first configuration are unavailable, that is, the DRX configuration of the SL provided by the second UE cannot be used. In the embodiment of the present disclosure, the first UE uses the default first configuration, that is, the first UE uses the DRX configuration determined according to the communication protocol, or uses the current DRX configuration, or uses the default DRX configuration of the first UE, to ensure the DRX communication of the first UE and save power of the first UE.

[0240] The present disclosure provides a communication configuration method, which is performed by a first UE. The method may include:

[0241] In response to the first UE determining that configurations other than the DRX configuration in the SL configuration are unavailable, a default second configuration is used, wherein the default second configuration may be: configurations other than the DRX configuration in the SL configuration determined by the first UE according to the communication protocol, or configurations other than the DRX configuration in the current SL configuration of the first UE, or configurations other than the DRX configuration in the default SL configuration of the first UE.

[0242] In a possible implementation, other configurations except the DRX configuration in the SL configuration determined by the first UE according to the communication protocol may be other configurations except the DRX configuration in the SL configuration determined by the communication protocol used by the first UE before receiving the SL configuration provided by the second UE. Other configurations except the DRX configuration in the current SL configuration of the first UE may be other configurations except the DRX configuration in the SL configuration currently being used by the first UE. Other configurations except the DRX configuration in the SL configuration of the default SL configuration of the first UE may be other configurations except the DRX configuration in a default SL configuration pre-set for the first UE. Other configurations except the DRX configuration in the default SL configuration and other configurations except the DRX configuration in the SL configuration provided by the second UE. In one possible implementation, the other configurations in the default SL configuration except the DRX configuration may be other configurations in the current SL configuration except the DRX configuration, or may not be other configurations in the current SL configuration except the DRX configuration. When the other configurations in the SL configuration except the DRX configuration provided by the second UE received by the first UE are not available, the first UE may change from the other configurations in the currently used SL configuration except the DRX configuration to the other configurations in the default SL configuration except the DRX configuration.

[0243] In a possible implementation, the first UE may determine to use the default second configuration before, when, or after sending the second indication. It should be noted that since the second indication is used to indicate that one or more SL configurations in the second configuration are unavailable, that is, other configurations of the SL provided by the second UE except the DRX configuration are unavailable. In the embodiment of the present disclosure, the first UE ensures normal communication of the first UE by using the default second configuration, that is, the first UE uses other configurations in the SL configuration determined according to the communication protocol except the DRX configuration, or uses other configurations in the current SL configuration except the DRX configuration, or uses other configurations in the default SL configuration of the first UE except the DRX configuration.

[0244] In some exemplary embodiments, the SL is configured as follows: the second UE sends a SL reconfiguration message via a radio resource control RRC.

[0245] Please refer to Figure 2 or Figure 3 The RRC reconfiguration SL message may be an RRCReconfigurationSidelink message.

[0246] In this embodiment, the SL configuration provided by the second UE is carried in the RRC reconfiguration SL message, so that the first UE can perform configuration feedback based on the RRC reconfiguration message without occupying other communication resources. The communication configuration method described in the above embodiment can be implemented using the original communication resources, making the communication configuration method simpler to implement and more versatile.

[0247] It should be noted that those skilled in the art can understand that the method provided in the embodiments of the present disclosure can be executed alone or together with some methods in the embodiments of the present disclosure or some methods in related technologies.

[0248] The following information processing method is performed by the second user equipment UE, which is similar to the communication configuration method performed by the first UE mentioned above; and for technical details not disclosed in the embodiment of the communication configuration method performed by the second UE, please refer to the description of the example of the communication configuration method performed by the first UE, and no detailed description is given here.

[0249] like Figure 7 As shown, a communication configuration method is provided, which is performed by a second user equipment UE, including:

[0250] Step S71: Receive indication information sent by the first UE via the direct link SL, wherein the indication information at least indicates: one or more sets of SL configurations used by the first UE, or one or more sets of SL configurations used by the first UE.

[0251] In some embodiments of the embodiments of the present disclosure, the indication information may be the indication information in step S41; the SL may be the SL in step S41, the first UE may be the first UE in step S41, and the second UE may also be the second UE in step S41.

[0252] In some exemplary embodiments, the SL configuration includes: a first configuration, the first configuration including: one or more sets of discontinuous reception DRX configurations of the SL.

[0253] like Figure 8 As shown, the embodiment of the present disclosure provides a communication configuration method, which is performed by a second UE and includes:

[0254] Step S711: receiving a first indication sent by the first UE through the SL, wherein the first indication is used to indicate that one or more DRX configurations in the first configuration are unavailable;

[0255] or

[0256] Step S713: Receive a second indication sent by the first UE through the SL, wherein the second indication is used to indicate that one or more DRX configurations in the first configuration are available.

[0257] In some embodiments of the embodiments of the present disclosure, the SL configuration includes: a second configuration, and the second configuration includes: other configurations of the SL except the DRX configuration.

[0258] In some exemplary embodiments, the second configuration includes at least one of the following:

[0259] Data transmission configuration;

[0260] SL bearer configuration;

[0261] Other SL configurations except DRX configuration.

[0262] like Fig. 9 As shown, the embodiment of the present disclosure provides a communication configuration method, which is performed by a second UE and includes:

[0263] Step S712: receiving a first indication sent by the first UE through the SL, where the first indication is used to indicate that one or more SL configurations in the second configuration are available;

[0264] or

[0265] Step S714: Receive a second indication sent by the first UE via the SL, where the second indication is used to indicate that one or more SL configurations in the second configuration are unavailable.

[0266] In some exemplary embodiments, the first indication includes:

[0267] A first configuration request indication, wherein the first configuration request indication is used to indicate a DRX configuration requesting the second UE to send a new SL.

[0268] In some exemplary embodiments, the second indication includes:

[0269] A second configuration request indication, wherein the second configuration request indication is used to indicate other configurations other than the DRX configuration for requesting the second UE to send a new SL.

[0270] The present disclosure provides a communication configuration method, which is performed by a second UE. The method includes at least one of the following:

[0271] In response to the indication information indicating that the DRX configuration in the SL configuration is unavailable, determining that the first UE uses a default first configuration, wherein the default first configuration is: a DRX configuration determined by the first UE according to the communication protocol, or a current DRX configuration of the first UE, or a default DRX configuration of the first UE;

[0272] In response to the indication information indicating that the DRX configuration in the SL configuration is unavailable, stopping the timing of the timer on the SL;

[0273] In response to the indication information indicating that the DRX configuration in the SL configuration is unavailable, a third indication is sent to the base station, wherein the third indication is used to indicate that the DRX configuration in the SL configuration provided to the first UE is unavailable.

[0274] Exemplarily, if the indication information received by the second UE indicates that the DRX configuration in the SL configuration is unavailable, indicating that the first UE cannot use the first configuration; then it is determined that the first UE uses the default first configuration, so that the second UE can communicate with the first UE according to the default first configuration, thereby reducing the loss of data sent by the second UE to the first UE due to the first UE being in a sleep state, etc., thereby improving communication performance.

[0275] In addition, please refer to Figure 2 and Figure 3 The second UE sends a feedback message of the RRC reconfiguration SL message to the first UE, for example, after the configuration fails, the inactivity timer is started. If the inactivity timer times out, the SL link failure is triggered, and the PC5-RRC connection and all SL bearers are released.

[0276] Here, the SL timer may be an inactive timer started after the second UE sends an RRC reconfiguration SL message. Exemplarily, the SL timer may be a T400 timer.

[0277] In this embodiment, if the second UE receives the indication information, it actively stops the timing of the SL timer to reduce the SL link disconnection phenomenon caused by timer timeout.

[0278] Exemplarily, in a scheduling scenario between a second UE and a first UE in which a base station participates, if the second UE receives indication information sent by the first UE, and the configuration information indicates that the DRX configuration in the SL configuration is unavailable, the second UE will report to the base station a message indicating that the configuration of the DRX configuration in the SL configuration provided to the first UE has failed. In a possible implementation, the third indication here may indicate that the second UE has failed to configure the first UE for the first configuration.

[0279] In this embodiment, the base station of the second UE can clearly know which configuration of the first UE failed, reducing the time for reconfiguration attempts of different SL configurations due to the base station's inability to know the unusable SL configuration, thereby improving the base station's configuration efficiency of the first UE through the second UE.

[0280] In some exemplary embodiments, sending a third indication to a base station includes:

[0281] In response to the second UE being in a connected state with the base station, a third indication is sent to the base station.

[0282] In this embodiment, the third indication is sent to the base station only when the second UE is in a connected state with the base station, thereby reducing data loss caused by transmission without connection between the second UE and the base station.

[0283] The present disclosure provides a communication configuration method, which is performed by a second UE and includes at least one of the following:

[0284] In response to the indication information indicating that other configurations except the DRX configuration in the SL configuration are unavailable, determining that the first UE uses a default second configuration, wherein the default second configuration is: other configurations except the DRX configuration in the SL configuration determined by the first UE according to the communication protocol, or other configurations except the DRX configuration in the SL configuration determined by the first UE according to the communication protocol, or other configurations except the DRX configuration in the default SL configuration of the first UE;

[0285] In response to the indication information indicating that other configurations except the DRX configuration in the SL configuration are unavailable, stopping the timing of the timer on the SL;

[0286] In response to the indication information indicating that other configurations except the DRX configuration in the SL configuration are not available, a fourth indication is sent to the base station, wherein the fourth indication is used to indicate that the configuration except the DRX configuration of the SL provided to the first UE has failed.

[0287] In this embodiment, if other configurations except the DRX configuration in the indication information SL configuration are not available, in one possible implementation method, it can be indicated that the first UE cannot use the second configuration; then it is determined that the first UE uses the default second configuration, so that the second UE can communicate with the first UE according to the default second configuration, thereby improving communication performance.

[0288] In addition, please refer to Figure 2 and Figure 3 , the second UE sends a feedback message of the RRC reconfiguration SL message to the first UE, such as the RRCReconfigurationSidelink message of the configuration failure, and starts the inactivity timer. If the inactivity timer times out, it triggers the SL link failure and releases the PC5-RRC connection and all SL bearers.

[0289] Here, the SL timer may be an inactive timer started after the second UE sends an RRC reconfiguration SL message. Exemplarily, the SL timer may be a T400 timer.

[0290] In this embodiment, if the second UE receives the indication information, it actively stops the timing of the SL timer to reduce the SL link disconnection phenomenon caused by timer timeout.

[0291] Exemplarily, in a scheduling scenario between a second UE and a first UE in which a base station participates, if the second UE receives an indication message sent by the first UE, and the indication message indicates that other configurations in the SL configuration except the DRX configuration are not available, the second UE will report to the base station a message indicating a configuration failure of other configurations in the SL configuration except the DRX configuration provided to the first UE. In a possible implementation, the fourth indication here may indicate that the second UE has failed to configure the first UE with respect to the second configuration.

[0292] In this embodiment, the base station of the second UE can clearly know which configuration of the first UE failed, reducing the time for reconfiguration attempts of different SL configurations due to the base station's inability to know the unusable SL configuration, thereby improving the base station's configuration efficiency of the first UE through the second UE.

[0293] In some exemplary embodiments, sending a fourth indication to a base station includes:

[0294] In response to the second UE being in a connected state with the base station, a fourth indication is sent to the base station.

[0295] In this embodiment, the fourth indication is sent to the base station only when the second UE is in a connected state with the base station, thereby reducing data loss caused by transmission without connection between the second UE and the base station.

[0296] The present disclosure provides a communication configuration method, which is performed by a second UE, and the method further includes:
