In some embodiments of the present disclosure, to support direct communication between UEs, a sidelink communication scheme is introduced, and the interface between UEs may be PC-5. According to the corresponding relation between the sending UE and the receiving UE, three transmission modes, namely unicast, multicast and broadcast, are supported on the sidelink. The transmitting UE transmits sidelink control information (Sidelink Control Information, SCI) on a physical side uplink control channel (Physical Sidelink Control Channel, PSCCH) channel and a second stage SCI on a physical side uplink shared channel (Physical Sidelink Shared Channel, pscsch), carrying the resource location of the transmitted data, source and destination identities, etc. After receiving the SCI, the receiving UE determines whether to receive the corresponding data and which process according to the source UE and the destination UE identification. In a unicast connection, each UE corresponds to a destination identifier, in a multicast, each UE may belong to one or more groups, each group corresponding to a destination identifier, in a broadcast, all UEs correspond to at least one destination identifier.

In some embodiments, to save power consumption of the sidelink UE, sidelink discontinuous reception (Discontinuous Reception, DRX) is introduced. The receiving UE monitors the PSCCH and the second stage SCI on the PSSCH only in the activation time, thereby achieving the purpose of energy saving. The transmitting UE may send the sidelink data only in the activation time of the receiving UE, so as to avoid data loss. The activation time includes the wake-up timer, the inactivity timer and the retransmission timer run period.

In some embodiments, the SL DRX configuration includes a sidelink DRX cycle (cycle), a start offset (offset), a timer duration, including a sidelink wakeup timer (sidelink on-duration timer), a sidelink inactivity timer (sidelink inactivity timer), a sidelink round trip time timer (sidelink RTT timer), and a sidelink retransmission timer (sidelink Retransmission timer).

In some embodiments, unicast SL DRX is transmitted by the transmitting UE to the receiving UE, which may transmit assistance information to the transmitting UE, the assistance information including the proposed SL DRX configuration. Only one set of SL DRX can be transmitted.

In some embodiments, one UE may not directly connect to the base station but communicate with the base station through a relay of another UE, where a UE that is not connected to the base station may be referred to as a remote UE (remote UE), a UE that provides a relay function may be referred to as a relay UE (relay UE), and a architecture referred to as U2N (UE to NW) relay may be referred to as a relay UE that communicates with the relay UE through a sidelink unicast.

In some embodiments, the remote UE may maintain communication with the network through the relay UE even though the remote UE cannot receive the base station signal, and thus may expand coverage of the network.

In some embodiments, a UE in a connected state, an idle state, or an inactive state may receive broadcast traffic transmitted by a base station (Broadcast Service).

In some embodiments, the base station transmits a multicast broadcast service broadcast configuration (MBSBroadcastConfiguration) message on a multicast broadcast service control channel (MBS Control Channel, MCCH) carrying a multicast broadcast service information List (MBSSessionInfoList) provided by the current cell, a DRX configuration List (DRX-configpm-List) and a neighbor cell List (MBSNeighbourCellList) providing the multicast broadcast service.

In some embodiments, one or more pieces of multicast or broadcast service information may be carried in the multicast broadcast service list, where each piece of multicast or broadcast service information indicates a temporary mobile group identity (Temporary Mobile Group Identity, TMGI), a group RNTI (group radio network temporary identity, G-RNTI), a broadcast service radio bearer configuration, a neighbor list supporting the multicast broadcast service, and a DRX configuration for the multicast broadcast service. Wherein the TMGI is used to identify multicast or broadcast services, the radio bearer configuration for broadcast services indicates PDCP, and RLC configuration. Optionally, the DRX configuration of the multicast broadcast service is an index identifier, which is used to determine a DRX configuration in the DRX-configpm-List.

In some embodiments, to save power consumption of the UE on the Uu port, the network device may configure discontinuous reception (Discontinuous Reception, DRX) for the UE.

In some embodiments, the UE needs to monitor the PDCCH channel continuously, and the base station sends control information on the PDCCH channel to schedule uplink and downlink resources for the UE. In order to save the energy consumption of the UE, a DRX function is introduced, and the UE decides whether to be in an active state or not according to the DRX configuration. In the active state the UE needs to monitor PDCCH and in the sleep state the UE does not need to monitor PSCCH. Therefore, the time for the UE to monitor the PDCCH can be reduced, and the purpose of saving electricity is achieved.

In the above embodiments, the remote UE may need to receive unicast, broadcast, multicast traffic simultaneously. The arrival period and delay requirements of these three services may be different. Using only one SL DRX configuration to control the sidelink listening may result in the UE additionally listening to the sidelink channel, resulting in power costs.
