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: A cell selection or reselection method includes that a terminal device obtains first information that corresponds to a first cell and that is not specific to a frequency band or a frequency. When a first condition that corresponds to the first information and that is used to determine whether the terminal device can access the first cell is not met, the terminal device is allowed to select or reselect a cell on a same frequency as the first cell.

Abstract: This application relates to the field of communication technologies, and discloses a communication method and apparatus. The method includes: A terminal device receives indication information from a first access network device. The indication information is used to indicate to fall back a capability of the terminal device to a first protocol version. The terminal device communicates, based on the indication information, with the first access network device by using first capability information. A protocol version corresponding to the first capability information is lower than or equal to the first protocol version. In this method, because a network device can explicitly indicate to fall back the capability of the terminal device to the first protocol version, the terminal device can specially reduce the capability, so as to quickly resolve a communication problem caused by incompatibility between the terminal device and the access network device.
