摘要： A method includes: triggering, by a terminal device, a scheduling request (SR); in response to determining that a physical uplink control channel (PUCCH) carrying the SR and a physical uplink shared channel (PUSCH) carrying a first data packet overlap in time domain of a first uplink resource and a processing status of the PUSCH on the first uplink resource is processing completed, sending, based on the processing status of the PUSCH on the first uplink resource, the PUCCH on an overlapping time domain resource. According to the method, when the PUCCH carrying the SR and the PUSCH overlap in time domain of the first uplink resource, the terminal device considers the processing status of the PUSCH on the first uplink resource, and may determine, based on the processing status of the PUSCH on the first uplink resource, to send the PUCCH or the PUSCH on the overlapping time domain resource.

摘要： 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.

摘要： A first terminal device has first data to be transmitted on a sidelink and has second data to be transmitted on an uplink. The first terminal device performs medium access control MAC protocol data unit PDU assembly on the first data or does not perform MAC PDU assembly on the first data based on a result of comparison between a transmission priority of the first data and a transmission priority of the second data.

摘要： 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.

摘要： A data integrity protection method and apparatus in a network environment are described. A terminal device obtains an integrity protection algorithm and a key corresponding to a session or a flow, and a DRB corresponding to the session. The terminal device performs, by using the integrity protection algorithm and the key corresponding to the session, integrity protection on data of the DRB corresponding to the session or the flow, where one session includes a plurality of flows. Different integrity protection algorithms and keys can be used for different sessions, and different integrity protection algorithms and keys can also be used for different flows. In this way, integrity protection is more flexible and meets security requirements of a same user for different services.
