Abstract: Example data sending methods and apparatus are described. One example method includes sending a first message to a network device by a terminal device. The first message is used to indicate information about remaining time of each of one or more data packets. The remaining time of each of the one or more data packets is used to indicate that the terminal device needs to finish sending each of the one or more data packets before the end of the remaining time. The terminal device obtains information about a resource configured by the network device for the terminal device, wherein the resource is used to send each of the one or more data packets before the end of the remaining time.

Abstract: An embodiment of this application provides a communications method. The method includes: generating, by an first base station, a radio resource control release message on which encryption and integrity protection are performed by using a new key; and sending, by the first base station, the radio resource control release message to a second base station, thereby improving security of communication between the serving device and the terminal and reducing signaling overheads for performing key negotiation over an air interface.

Abstract: A terminal device generates a report result including at least one of a logged minimization of drive tests report, an RLF report, and an RACH report. The logged minimization of drive tests report includes an identifier of a candidate access cell, information indicating whether the candidate access cell supports a network slice service initiated by the terminal device, location information of the terminal device where the terminal device receives a system message of the candidate access cell, and a network slice identifier of the network slice service initiated by the terminal device. The RLF report includes an identifier of a cell in which a radio link failure occurs after the terminal device accesses the cell and the network slice identifier corresponding to the network slice service in which the radio link failure occurs on the terminal device. The RACH report includes an identifier of a cell accessed by the terminal device and the network slice identifier. The terminal device sends the report result to a radio access network device to which a serving cell belongs.

Abstract: Embodiments of this application provide a data transmission method and an apparatus. When a time-frequency resource used by a terminal device for data transmission is unavailable, the terminal device postpones, based on indication information of a network device and/or according to a postponement rule, the data transmission to a time-frequency resource closest to the time-frequency resource. Therefore, a data transmission latency is reduced.

Abstract: An access network device sends first information and second information to a terminal, where the first information includes a value set of a communication time interval, and the second information indicates a value of the communication time interval in the value set, and the value is used to determine timing duration of a hybrid automatic repeat request (HARQ) round trip time (RTT) timer. The communication time interval includes at least one of a time interval from the terminal receiving downlink scheduling grant information to the terminal receiving downlink data scheduled by using the downlink scheduling grant information, a time interval from the terminal receiving downlink data to the terminal sending HARQ feedback information of the downlink data, and a time interval from the terminal receiving uplink scheduling grant information to the terminal sending uplink data scheduled by using the uplink scheduling grant information.

Abstract: Embodiments of this application provide a data transmission method and apparatus. The method includes: receiving data sent by a terminal in an inactive state, where the data includes to-be-sent data sent by the terminal and identification information of the terminal; determining an anchor base station of the terminal based on the identification information; and sending the data to the anchor base station, so that the anchor base station sends the data to a core-network device. The uplink data of the terminal is forwarded to the anchor base station by using a serving base station and through an interaction between the anchor base station and the serving base station that currently provides an air interface resource for the terminal, and is then transmitted to a core network.

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.
