    Abstract: This application provides a communications method and apparatus. According to the method, a receiving terminal receives, from one or more sending terminals, X PSSCHs that are in a one-to-one correspondence with X PSFCH resources, determines M PSFCH resources based on priorities of the X PSFCH resources, transmit power corresponding to the X PSFCH resources, and total transmit power of the receiving terminal, and sends feedback information to some or all of the one or more sending terminals on the M PSFCH resources, so that the receiving terminal can send the M PSFCH resources based on a sending capability (namely, the total transmit power) of the receiving terminal. This improves overall performance of a network system.

    Abstract: This application relates to the field of wireless communications technologies, and provides an indication method, an indication determining method, a sending device, and a receiving device, to resolve a problem existing in a transmission technology solution in which a slot format is indicated by using single indication information. The indication determining method includes: receiving, by a receiving device in a first slot, first indication information and second indication information that are sent by a sending device; and determining, by the receiving device, that the first indication information indicates a slot format of the first slot, and that the second indication information indicates a slot format of a second slot, where the second slot is a slot after the first slot. This application is applicable to a scenario in which a slot format is configured for a slot.

    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.
