Abstract: This application relates to a discontinuous reception method. In the first time unit, for example, the first symbol, after a hybrid automatic repeat request HARQ feedback occasion of a sidelink HARQ process, a first terminal may start a drx-HARQ-RTT-TimerSL and start a drx-RetransmissionTimerSL when the drx-HARQ-RTT-TimerSL expires. During running of the drx-RetransmissionTimerSL, the first terminal monitors a physical downlink control channel. In this way, sidelink retransmission efficiency can be improved, an increase of a sidelink retransmission delay can be avoided, and sidelink-based applications, such as unmanned driving, automatic driving, assisted driving, intelligent driving, networked driving, intelligent networked driving, and car sharing in the field of artificial intelligence can be better supported.

Abstract: Terminal apparatus identification methods and apparatuses are described. An access stratum (AS) of a first communications apparatus sends first information to an AS of a second communications apparatus. The AS of the second terminal apparatus may identify a leader terminal apparatus based on the first information, so as to implement perception of the leader terminal.

Abstract: This application discloses a sidelink (SL) communication method and an apparatus. In this application, the second terminal receives first control information and first data from the first terminal, where a cast type indicated by the first control information is SL groupcast transmission with negative acknowledgement (NACK) only feedback. The second terminal starts a first timer at a specified location after a hybrid automatic repeat request (HARQ) feedback resource corresponding to the first data, where duration of the first timer indicates minimum duration that elapses before SL resource scheduling information used for HARQ retransmission is expected to be received. After the first timer expires, if the second terminal successfully decodes the first data and detects a NACK on the HARQ feedback resource, the second terminal starts a second timerwith duration indicating maximum duration that elapses before the SL resource scheduling information used for HARQ retransmission is received.
