Abstract: Example communication methods and apparatus are described. One example communication method includes receiving indication information by a terminal device from a network device, where the indication information is used to indicate resource configuration information of a first uplink carrier and/or a second uplink carrier. The first uplink carrier and the second uplink carrier are different uplink carriers in a cell of the network device, and the first uplink carrier and the second uplink carrier are corresponding to one downlink carrier in the cell. The terminal device determines one uplink carrier from the at least one uplink carrier as a target carrier for performing random access based on the resource configuration information of the at least one uplink carrier.

Abstract: This application provides a communication method in which a network device indicates in advance that a first beam is available for beam switching, and a terminal device reports a first measurement report corresponding to the first beam. The terminal device can determine, without waiting for a beam management instruction delivered by the network device, whether the first beam can be used for beam switching, so that a delay in a beam management process can be reduced, thereby improving communication quality. In this method, a terminal device receives first indication information from a network device, where the first indication information indicates that a first beam associated with at least one reference signal (RS) corresponding to a first reporting configuration is for beam switching.

Abstract: This application discloses a resource multiplexing method and apparatus. In this application, a first node receives first configuration information sent by a second node, where the first configuration information includes first guard interval information associated with a first timing mode of an MT. The first node receives second configuration information sent by the second node, where the second configuration information includes second guard interval information associated with a second timing mode of the MT. Guard interval information configured by the second node is associated with different timing modes, so that the first node can obtain the guard interval information corresponding to the different timing modes, to improve flexibility of resource multiplexing performed on an access link and a backhaul link.
