Abstract: A terminal device obtains first subgroup configuration information corresponding to a first PLMN, and receives paging from a first cell based on the first subgroup configuration information. The first PLMN is a PLMN associated with the terminal device, the first PLMN belongs to a PLMN set, and the PLMN set is associated with the first cell. Subgroup configuration information may be considered as configuration information for grouping terminal devices, and a terminal device may determine, based on the subgroup configuration information, a terminal device group to which the terminal device belongs.

Abstract: A first base station determines that a first terminal in a first cell is handed over to a second cell, where the first terminal belongs to a group of terminals, and the first cell belongs to the first base station. The first base station sends first information to the first terminal, where the first information indicates a first sidelink resource used by the group of terminals to perform communication, and the first sidelink resource is valid in both the first cell and the second cell. The foregoing technical solution resolves a problem that is of communications resource configuration of a group of terminals and that exists when the group of terminals perform handover.

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.

Abstract: Embodiments of this application provide a resource preemption method, an apparatus, and a system, to reduce a quantity of times of frequent resource preemption, and improve resource security. In one example, a first terminal device obtains a first time interval and a second time interval, and preempts or determines not to preempt a first resource according to a first preset rule. The first resource is a resource reserved by a second terminal device or a resource reserved for a first service to be transmitted by the first terminal device. The first time interval is a time interval related to the first resource. The second time interval is used to indicate a preemption forbidden time. The first preset rule is determined based on the first time interval and the second time interval.

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: This application provides a sidelink configuration method and apparatus, a device, and a storage medium. In one example, before each sidelink transmission is performed, a terminal device at a transmit end sends SCI to a terminal device at a receive end. In this solution, transmission on information needed for sidelink transmissions is performed by using sidelink RRC, so that the terminal device at the receive end obtains a time-frequency resource configuration of sidelink transmissions, and further obtains a HARQ process identifier of each transmission.
