Abstract: Embodiments of this application disclose a data transmission method and an apparatus. The method includes: When a terminal device is in a radio resource control RRC inactive state, the terminal device selects a first synchronization signal block SSB at first time, and sends first small data transmission SDT data to a network device by using a first configured grant CG resource corresponding to the first SSB; and when signal quality of a plurality of SSBs at second time is greater than a first threshold, the terminal device preferentially selects the first SSB from the plurality of SSBs at the second time, and sends second SDT data to the network device by using a second CG resource corresponding to the first SSB.

Abstract: This application provides a data sending method, a data sending apparatus, and a terminal device, to improve utilization of a configured grant resource. The method includes: A terminal device receives a configuration message from a network device. The configuration message is used to indicate a configured grant, and the configuration message includes information about a timer corresponding to the configured grant. The terminal device determines that the configured grant is used for a HARQ process, and starts the timer for the HARQ process. To-be-sent data in the HARQ process is data on a first logical channel. During running of the timer, when there is to-be-newly-transmitted data on a second logical channel, the timer stops running, or a running state of the timer is ignored. The data on the second logical channel is sent by using the configured grant.

Abstract: A communications method and apparatus are provided. The method includes: A first access network device sends a first message to a core network device, where the first message is used to indicate to suspend one or both of a first PDU session and a second PDU session. The first PDU session and the second PDU session are PDU sessions that are established as requested by a same terminal, and are used to transmit a duplicated data packet. According to the method, when a condition for implementing reliable transmission is not met, the core network device can be indicated to suspend the PDU session. In this way, a PDU session does not need to be re-established, and signaling overheads for establishing the PDU session are saved.

Abstract: This application provides a method for configuring assistance information and a communications apparatus. A first network device sends a path switch request message to an access and mobility management function (AMF), where the path switch request message is used to request for switching least one radio bearer (RB) of a terminal device from a second network device to the first network device. The first network device receives a path switch request response message from the AMF. The first network device determines, based on the path switch request response message, first burst arrival time at which a downlink quality of service QoS flow arrives at an ingress of the first network device within a first periodicity, where the first burst arrival time is used for downlink scheduling.
