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: Embodiments of this application provide a communication method, a terminal and a base station. The method includes: receiving, by a terminal, a scheduling request resource configuration sent by a base station, where the scheduling request resource configuration indicates an uplink resource type or logical channel information; and sending, by the terminal, a scheduling request to the base station via a target scheduling request resource based on the scheduling request resource configuration and uplink data, where the target scheduling request resource indicates a target uplink resource type, and the scheduling request resource configuration includes the target scheduling request resource. In the embodiments of this application, when diversity of the uplink data is considered, the base station configures different scheduling request resources for different service characteristics, and the terminal selects different scheduling request resources for different service characteristics, to improve effectiveness of uplink service transmission.
