Abstract: A communication method includes determining, by an access network device, that first information from a terminal device is not received in a first bandwidth part (BWP). The first BWP is an active BWP for the terminal device. The first BWP does not include common search space (CSS) used to transmit a system information block (SIB). The first information is associated with a system information update. The communication method also includes sending, by the access network device, updated system information to the terminal device in the first BWP in response to determining that the first information is not received.

Abstract: A communication method includes obtaining, by a terminal device or a chip in the terminal device, configuration information of a multicast service. The configuration information is useable by the terminal device to receive data of the multicast service. The method further includes receiving first indication information from an access network device. The first indication information is useable to indicate a manner of obtaining configuration update information of the multicast service by the terminal device. The manner of obtaining the configuration update information of the multicast service is a first manner or a second manner. The first manner is obtaining the configuration update information by receiving a common message. The second manner is obtaining the configuration update information by receiving a dedicated message.

Abstract: A method to resolve a problem of resource waste caused by a communication device listening to, on all listening occasions, information scrambled by using a first radio network temporary identifier RNTI. A network device determines a mapping period of a first RNTI, where in the mapping period, a beam and a listening occasion form a mapping relationship, so that the network device sends, to a terminal device on a target listening occasion by using a target beam, information scrambled by using the first RNTI. The terminal device receives, on the target listening occasion by using the target beam, the information scrambled by using the first RNTI.

Abstract: This application provides a random access resource selection method. The method includes: A terminal device obtains reference information; and when determining that a first parameter and the reference information meet a preset condition, selects a primary frequency domain resource or a non-primary frequency domain resource based on a first probability and a second probability, to initiate random access. There is a correspondence between the first probability and the primary frequency domain resource, and there is a correspondence between the second probability and the non-primary frequency domain resource. In embodiments of this application, frequency resources are selected, based on different probabilities, for random access triggered by an emergency and random access triggered by another event.
