Abstract: This application provides a communication method and a communications apparatus, to provide a solution for processing a conflict between uplink resources. The method includes: a terminal device obtains a first uplink resource, where the first uplink resource is used to send a first service. The terminal device obtains a second uplink resource, where the second uplink resource is used to send a second service, and the first uplink resource and the second uplink resource completely or partially overlap in a time domain. The terminal device determines a target uplink resource to be used in the time domain, where the target uplink resource is the first uplink resource or the second uplink resource. The terminal device sends data on the target uplink resource in the time domain.

Abstract: Embodiments of this application provide a communication method, apparatus, a terminal, a network device, and a storage medium. After the terminal receives, from the network device, indication information used to indicate the terminal to report traffic pattern information of a first logical channel, a first PDU session, a first application, a first radio bearer, or a first QoS flow, the terminal reports the traffic pattern information of the first logical channel, the first PDU session, the first application, the first radio bearer, or the first QoS flow based on the indication information. In this manner, the terminal reports, based on the indication, the traffic pattern information of only the logical channel, the PDU session, the service, the radio bearer, or the QoS flow that is indicated by the network device.
