[0002] To support direct communication between user equipment (UE), a sidelink communication method was introduced. Sidelink is sometimes also called a secondary link or a direct link. A UE can communicate directly with a network device.

[0060] To facilitate understanding of the embodiments of the present application, some terms used in the embodiments of the present application are explained below to facilitate understanding by those skilled in the art.

[0061] 1) User equipment

[0062] User equipment includes devices that provide voice and / or data connectivity to users. Specifically, it includes devices that provide voice to users, devices that provide data connectivity to users, or devices that provide voice and data connectivity to users. For example, it may include a handheld device with wireless connection capabilities, or a processing device connected to a wireless modem. As an example, user equipment may include wireless user equipment, mobile user equipment, or user equipment (user device). In the embodiments of the present disclosure, user equipment may also be referred to as a terminal.

[0063] 2) Sidelink (SL)

[0064] Sidelinks, also known as edge links or sidelinks, are used for communication between user devices, including one-to-one sidelink communications and one-to-many sidelink communications. One-to-one sidelink communications may include unicast, while one-to-many sidelink communications may include broadcast and multicast. For example, broadcast may refer to communication with all user devices within a cell, and multicast may refer to communication with user devices in a communication group, which may include one or more user devices. Sidelink communications may include direct communication between two user devices or sidelink communications forwarded by a relay node.

[0065] 3) PC-5 interface

[0066] The PC-5 interface is used for wireless communication between user devices. That is, one user device communicates with another user device through the PC-5 interface. Sidelink communication between two user devices can also be performed through the PC-5 interface.

[0067] 4) Quality of service (QOS)

[0068] QoS is a network security mechanism and a technology used to address issues such as network latency and congestion. Traditionally, quality of service (QoS) encompasses transmission bandwidth, transmission latency, and packet loss rate. Improving QoS involves ensuring transmission bandwidth, reducing transmission latency, packet loss rate, and jitter.

[0069] 5) Discontinuous Reception (DRX)

[0070] Discontinuous reception (DRX) means that the user equipment turns on the receiver and enters an active state (active state) only when necessary to receive data and signaling. At other times, the receiver is turned off and enters a dormant state (inactive state). When the user equipment is in the dormant state, the user equipment stops receiving data and signaling.

[0071] DRX is a power-saving operating mode for user equipment (UE). It is divided into idle DRX and connected DRX. Idle DRX is implemented by sensing the paging channel because it lacks an RRC (radio resource control) connection and a dedicated UE bearer. Connected DRX refers to the DRX feature when the UE is in the RRC connected state and is implemented by monitoring the physical downlink control channel (PDCCH).

[0072] To save power consumption in user equipment (UE), SL DRX was introduced in NR (New Radio) SL. Common timers in SL DRX include the sidelink on-duration timer, sidelink inactivity timer, sidelink retransmission timer, and sidelink RTT timer. The on-duration timer is also called the wake-up timer; RTT is the abbreviation for roundtrip time.

[0073] In related technologies, the Sidelink communication method has been introduced to support direct communication between user devices. The interface between user devices in Sidelink can be PC-5. Sidelink can support three transmission modes: unicast, multicast, and broadcast.

[0074] The transmitting user equipment may send sidelink control information (SCI) on the PSCCH (Physical Sidelink Control Channel). In addition, the transmitting user equipment may also send a second-stage SCI on the PSSCH (Physical Sidelink Shared Channel), which may carry the resource location, source, and destination identifiers of the transmitted data.

[0075] After receiving the SCI, the receiving user equipment can determine whether to receive the corresponding data and which process to receive it based on the source and destination user equipment identifiers. In a unicast connection, each user equipment can be associated with a sidelink identifier. After two user equipment establish a unicast connection, one user equipment can send a sidelink RRC message to the other user equipment. In a multicast connection, each user equipment can belong to one or more groups. In a broadcast connection, all user equipment are associated with at least one destination identifier.

[0076] To reduce power consumption in sidelink UEs, Release 17 introduced sidelink discontinuous reception (DRX). Receiving UEs can monitor the PSCCH and the second-stage SCI on the PSSCH during their active time, thereby saving energy. Furthermore, transmitting UEs can send sidelink data during the receiving UE's active time to avoid data loss. The active time can include a duration timer / wake-up timer, an inactivity timer, and a retransmission timer.

[0077] In some embodiments, the sending UE is able to determine the arrival time of the service, so the unicast SL DRX configuration can be sent by the sending UE to the receiving UE. In this process, the sending UE can send the SL DRX configuration to the receiving UE via an RRC reconfiguration message for sidelink (e.g., RRCReconfigurationSidelink), as shown in detail in FIG1 . In addition, after receiving the RRC reconfiguration message for sidelink sent by the sending UE, the receiving UE can send an RRC reconfiguration complete message for sidelink (e.g., RRCReconfigurationcompleteSidelink) to the sending UE to indicate that the RRC reconfiguration message for sidelink has been successfully received.

[0078] Specifically, the SL DRX configuration may include the sidelink DRX cycle (Cycle), starting offset (offset) and timer duration, among which the timer duration may include the duration of the sidelink continuous timer, the duration of the sidelink inactivity timer, the duration of the sidelink retransmission timer and the duration of the sidelink round-trip time timer, among others.

[0079] Optionally, the receiving UE may send assistance information to the sending UE, where the assistance information may include a recommended SL DRX configuration. Specifically, the assistance information may be sent via a UE assistance information message about sidelink (e.g., UEAssistanceInformationSidelink), as described in detail in FIG2 . Here, the recommended SL DRX configuration in the assistance information may include a starting offset and a sidelink on-duration timer duration.

[0080] As shown in Figure 3, the first user equipment can connect to the third user equipment through a relay function of the second user equipment instead of directly connecting to the third user equipment. The first user equipment and the third user equipment can be remote UEs, and the second user equipment providing the relay function can be a relay UE. The first user equipment, the second user equipment, and the third user equipment can communicate with each other via sidelink unicast. This architecture can be called U2U (UE-to-UE) relay.

[0081] In U2U relay, a first user equipment (UE) can simultaneously connect to multiple third user equipments (UEs) through a second user equipment (relay UE), as shown in Figure 4. Link 1 in Figure 4 can be used to transmit data sent from the first UE to third user equipments 1 and 2. Therefore, the SL DRX on Link 1 must take into account the arrival time of data sent from the first UE to third user equipments 1 and 2, ensuring that the second UE (relay UE) is active upon data arrival. The SL DRX on Link 1 can be configured by the first UE.

[0082] Optionally, Link 2 in Figure 4 can be used to transmit data sent by the first user equipment to the third user equipment 1, so the SL DRX on Link 2 can be used to consider the arrival time of the data sent by the first user equipment to the third user equipment 1, so that the third user equipment 1 is in an activated state when the data arrives.

[0083] Optionally, Link 3 in Figure 4 can be used to transmit data sent by the first user equipment to the third user equipment 2, so SL DRX on Link 3 can be used to consider the arrival time of the data sent by the first user equipment to the third user equipment 2, so that the third user equipment 2 is in an activated state when the data arrives.

[0084] In some embodiments, the SL DRX on Link 2 and Link 3 in Figure 4 can be configured by the second user equipment (relay UE). However, the second user equipment (relay UE) is not aware of the arrival time of the data sent by the first user equipment to the third user equipment 1 or the data sent by the first user equipment to the third user equipment 2. Therefore, the second user equipment cannot configure a reasonable SL DRX for Link 2 and Link 3. As a result, when the second user equipment (relay UE) forwards data, the target UE (third user equipment 1 or third user equipment 2) is not in an active state, resulting in transmission delay.

[0085] In order to solve the above problems, the embodiments of the present application provide a discontinuous reception (DRX) configuration method and apparatus, so that the U2U relay UE can reasonably configure the SL DRX of the target UE to avoid delays.

[0086] The following describes an application environment of a discontinuous reception DRX configuration method provided in this embodiment. As shown in Figure 5, the application scenario includes a first user device 11, a second user device 12, and a third user device 13, wherein the first user device 11, the second user device 12, and the third user device 13 can perform sidelink communication through the PC5 interface.

[0087] The first user equipment 11, the second user equipment 12, and the third user equipment 13 may be terminals (UEs) or other terminal-side devices, such as mobile phones, tablet personal computers, laptop computers, personal digital assistants (PDAs), mobile internet devices (MIDs), wearable devices, smart cars, in-vehicle devices, or robots. It should be noted that the present disclosure does not limit the specific type of terminal.

[0088] It is worth noting that in the system shown in Figure 5, the first user device 11 and the third user device 13 can communicate via a sidelink direct link. In other embodiments, the first user device 11 and the third user device 13 can also communicate via a sidelink indirect link. That is, the first user device 11 and the third user device 13 can communicate via the second user device 12 (relay UE). In this embodiment of the present application, the first user device 11 and the third user device 13 can be remote user devices, and the second user device 12 can be a relay user device.

[0089] Figure 6 is a flow chart illustrating a method for configuring discontinuous reception (DRX) according to some embodiments. As shown in Figure 6 , the method for configuring discontinuous reception (DRX) may be used in a first user equipment and includes the following steps.

[0090] In step S110, first configuration information is sent to the second user equipment, where the first configuration information is used to determine a sidelink DRX configuration of a third user equipment.

[0091] In the embodiment of the present disclosure, the first user equipment and the third user equipment may be remote devices, the second user equipment may be a relay device, and the first user equipment may communicate with the third user equipment through the second user equipment.

[0092] In some embodiments, the first user equipment may send first configuration information to the second user equipment, wherein the first configuration information may be used to determine a sidelink DRX configuration of the third user equipment. In addition, the first user equipment may send the first configuration information via a sidelink.

[0093] As an optional manner, the first configuration information may be sent via a sidelinkRRC message, where the sidelinkRRC message may be a user equipment assistance message for sidelink (e.g., UEAssistanceInformationSidelink), that is, the sidelinkRRC message may be a UE assistance message sidelink message. Optionally, the sidelinkRRC message may also be an RRC reconfiguration message for sidelink (e.g., RRCReconfigurationSidelink). Optionally, the sidelinkRRC message may also be a user equipment assistance message for sidelink and an RRC reconfiguration message for sidelink.

[0094] It should be noted that the first user equipment may send the first configuration information to the U2U relay, that is, the second user equipment may be the U2U relay.

[0095] An embodiment of the present application stipulates that a first user device can send first configuration information to a second user device, wherein the first configuration information is used to determine the direct link sidelink DRX configuration of a third user device, so that the second user device can reasonably configure the sidelink DRX configuration of the third user device, thereby avoiding delays.

[0096] Figure 7 is a flow chart of a method for configuring discontinuous reception (DRX) according to some other embodiments. As shown in Figure 7 , the method for configuring discontinuous reception (DRX) may be used in a first user equipment and includes the following steps.

[0097] In step S210, the identifier of the third user equipment is sent to the second user equipment through the first configuration information.

[0098] In some embodiments, the first user equipment may send an identifier of a third user equipment to the second user equipment via the first configuration information, where the identifier of the third user equipment is used to determine a unique target remote UE, i.e., the third user equipment may be determined based on the identifier of the third user equipment. The identifier of the third user equipment may be a sidelink identifier or a temporary identifier, where the sidelink identifier may be a sidelink layer 2 identifier.

[0099] In a specific embodiment, the temporary identifier can be allocated by the second user device (relay device) or can also be allocated by the network device. Through the temporary identifier, the embodiment of the present disclosure can uniquely determine a target user device (remote UE) among multiple third user devices (remote devices) connected to the second user device (relay device). In other words, the temporary identifier can correspond one-to-one with the third user device, that is, one temporary identifier can correspond to one third user device. For example, the identifier corresponding to the third user device 1 is temporary identifier 1, and the identifier corresponding to the third user device 2 is temporary identifier 2. Here, the temporary identifier can also be called a local identifier (local ID), and the local identifier can be an index. Specifically, the local identifier can be represented in binary, octal, decimal or hexadecimal.

[0100] Exemplarily, the local identifier is represented in binary. For example, the first user device is connected to 128 third user devices through the second user device. The local identifier of the first third user device can be represented as 0000000, the local identifier of the second third user device can be represented as 0000001, and the local identifier of the 128th third user device can be represented as 1111111. Therefore, the local identifier of each third user device can be represented by 7 bits.

[0101] As an optional approach, before sending the identifier of the third user device to the second user device, the first user device may determine whether there are at least two third user devices connected to the second user device. If it is determined that there are at least two third user devices connected to the second user device, the first user device may send the identifier of the third user device to the second user device via the first configuration information. As shown in Figure 4, there are two third user devices connected to the second user device. In this case, the first user device may send the identifier of the third user device to the second user device via the first configuration information.

[0102] Optionally, if it is determined that there is only one third user equipment connected to the second user equipment, the first user equipment may not carry the identifier of the third user equipment when sending the first configuration information.

[0103] It should be noted that, for multiple embodiments or features separated by "or", even if some of the features are not implementable, it will not affect other solutions. In addition, the embodiments of the present disclosure can be combined with other embodiments or implementation methods of the DRX configuration method for the first user equipment and their various optional solutions, unless there is any contradiction, and will not be repeated here.

[0104] An embodiment of the present application stipulates that a first user device can send an identifier of a third user device to a second user device via first configuration information, wherein the first configuration information is used to determine a direct link sidelink DRX configuration of the third user device, thereby enabling the second user device to reasonably and accurately configure the sidelink DRX configuration of the third user device, thereby avoiding delays.

[0105] Figure 8 is a flow chart of a method for configuring discontinuous reception (DRX) according to some further embodiments. As shown in Figure 8 , the method for configuring discontinuous reception (DRX) may be used in a first user equipment and includes the following steps.

[0106] In step S310, the identifier of the third user equipment and the sidelink DRX configuration of the third user equipment are sent to the second user equipment through the first configuration information.

[0107] In some embodiments, the first configuration information sent by the first user equipment to the second user equipment may include the identifier of the third user equipment and the sidelink DRX configuration of the third user equipment, that is, the first user equipment may send the identifier of the third user equipment and the sidelink DRX configuration of the third user equipment to the second user equipment.

[0108] Among them, the sidelink DRX configuration of the third user equipment may include a sidelink DRX cycle (Cycle), a starting offset (offset), a sidelink on-duration timer (sidelink on-duration timer) duration, a sidelink inactivity timer (sidelink inactivity timer) duration, a sidelink retransmission timer (sidelink Retransmission timer) duration, and a sidelink round-trip time timer (sidelink RTT timer) duration.

[0109] As an optional manner, the first user equipment may determine the sidelink DRX configuration of the third user equipment based on service attributes. Specifically, the first user equipment may determine the sidelink DRX configuration of the third user equipment based on service attributes (service arrival attributes), so that when the service arrives, SL DRX is activated. The service attributes may include at least one of a service quality of service (QoS) indication, a service period, a service start time, and a service latency requirement.
