Abstract: This application discloses a HARQ process control method and an apparatus, and relates to the field of communications technologies. The method includes: A first terminal apparatus determines that a TB transmitted in a first HARQ process is a first TB transmitted for the last time or a newly transmitted TB; and stops a first timer. Further, the first terminal apparatus sends, to a second terminal apparatus, first indication information used to indicate that the TB transmitted in the first HARQ process is a newly transmitted TB. The second terminal apparatus receives the first indication information, and stops a second timer based on the first indication information.

Abstract: A sidelink communication method and apparatus are provided. The method includes: A first communication device receives sidelink control information from a second communication device. The first communication device starts a first timer based on an SL HARQ feedback resource, where the SL HARQ feedback resource is used for transmitting a HARQ feedback of the sidelink control information or SL data scheduled by using the sidelink control information. The first communication device starts or skips starting a second timer based on the first timer. According to the method of embodiments of this application, the first communication device can start the first timer and the second timer associated with SL DRX.

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: A terminal device obtains a first group of parameters corresponding to a first mode. A network device obtains a second group of parameters corresponding to the first mode, where the first group of parameters correspond to the second group of parameters. When a compatibility problem exists between the terminal device and the network device, the terminal device initiates initial access to the network device based on the first group of parameters, and the network device accepts, based on the second group of parameters, the initial access initiated by the terminal device.
