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: Embodiments of this application disclose a communication method and a communications apparatus, and are used in the field of communications technologies, to resolve a problem of how to notify an access network device of an NR PC5 QoS parameter of a terminal. The method in one embodiment includes a home V2XCF that obtains an NR PC5 QoS parameter of a terminal, and the home V2XCF sends the NR PC5 QoS parameter to an access network device, such as a first network element that is in an EPS. The first network element receives the NR PC5 QoS parameter and sends the NR PC5 QoS parameter to an MME. After receiving the NR PC5 QoS parameter, the MME sends the NR PC5 QoS parameter to an access network device. The first network element may be an HSS or a PCRF.
