Abstract: Example communication methods and apparatus are described. One example communication method includes receiving indication information by a terminal device from a network device, where the indication information is used to indicate resource configuration information of a first uplink carrier and/or a second uplink carrier. The first uplink carrier and the second uplink carrier are different uplink carriers in a cell of the network device, and the first uplink carrier and the second uplink carrier are corresponding to one downlink carrier in the cell. The terminal device determines one uplink carrier from the at least one uplink carrier as a target carrier for performing random access based on the resource configuration information of the at least one uplink carrier.

Abstract: A method and system for mobility latency reduction in a hierarchical NR architecture is provided. In an embodiment, a method in a network component for handover of a UE includes configuring, by the network component, at least one TRP determined according to UE mobility information. The configuring the at least one target TRP is performed prior to the UE moving into a border area between the at least one target TRP and a first serving TRP. Configuring the at least one target TRP results in the at least one target TRP being configured to act as a secondary serving TRP to the UE. The method also includes configuring at least one target TRP and the UE with corresponding dedicated access resource and monitoring opportunities. The method also includes activating a connection and data communication between the UE and the at least one pre-configured secondary serving TRP.

Abstract: Embodiments of this application provide a data transmission method and device. The method includes: obtaining, by a first access network device, a first message from a second access network device, where the first message requests context information of a terminal device; and sending, by the first access network device, a data packet to the second access network device. The first access network device is a corresponding access network device of the terminal device before the re-establishment procedure, and the second access network device is a corresponding access network device when the terminal device initiates the re-establishment procedure.

Abstract: Embodiments of the present invention provide a communication method and a communications device. The method includes: sending, by a base station, a message including measurement configuration to UE, where the measurement configuration is used to request the UE to report a cell global identifier of a cell; obtaining, by the base station, a measurement report reported by the UE, where the measurement report corresponds to the measurement configuration and includes the cell global identifier of the cell and band information of the cell; and performing, by the base station, cell handover based on the band information and the cell global identifier of the cell. By means of the present invention, the base station obtains complete and accurate band information of the cell, so that the base station can perform accurate handover decision, thereby avoiding handover failure.

Abstract: A radio release control (RRC) connection release method includes: sending, by user equipment (UE), a first message to a base station, where the first message carries a preset RRC release time determining parameter or a first RRC release time; if the UE adds the first RRC release time to the first message, setting, by the UE, timing duration of a first timer based on the first RRC release time, and starting the first timer; and releasing, by the UE, an RRC connection when the first timer expires.
