Abstract: Embodiments of the present disclosure provide a data transmission method, user equipment, and an access network device. UE transmits air interface data to an access network device by using a serving cell set including at least two core serving cells that can independently serve the UE to transmit data, and initiates an RRC connection re-establishment process to the access network device only when detecting that all core serving cells in the serving cell set are unavailable. Data transmission is performed by using an available serving cell to the greatest extent. In other words, data transmission can be performed by using any available core serving cell, to reduce the dependence of data transmission between serving cells and minimize possibility of data transmission interruption, thereby improving data transmission robustness.

Abstract: A communication method and apparatus are provided, where the method includes: A first network device generates and sends a paging message to a second network device. The paging message is used to page a terminal device, the paging message includes first indication information, and the first indication information indicates that a paging range includes a non-terrestrial network
NTN cell and/or a terrestrial network TN cell. By applying the foregoing technical solution, the network device may determine an appropriate paging area based on a type of the terminal device or capability information of the terminal device, to avoid sending the paging message in an area that is not supported by the terminal device, so that overheads of paging signaling are effectively reduced.-

Abstract: This application provides a communication method and apparatus. The method includes: A terminal device receives indication information from a master node, where the indication information indicates that a key used for signaling transmission performed between the terminal device and a first secondary node by using a second SRB is a first key, the first key is a key used for signaling transmission performed between the terminal device and the master node by using a first SRB, and the first secondary node and the master node share one CU. In a scenario in which the master node and a secondary node share one CU, the terminal device determines that a key for signaling transmission performed between the terminal device and the secondary node is the same as a key for signaling transmission performed between the terminal device and the master node, which avoids complexity.

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 base station configures, for a terminal, a contention-free random access resource for a beam failure recovery request. After determining that a beam failure has occurred, the terminal performs random access, and retains the contention-free random access resource after the random access succeeds, so that a beam failure recovery latency and signaling overheads can be reduced.

Abstract: This application provides a communication method and a communication apparatus. In a multiple connectivity mobility scenario, a terminal device records information related to a secondary network device mobility process to generate a mobility report, and sends the mobility report to a network device. The network device determines, based on content in the mobility report, whether a mobility parameter related to the SN mobility needs to be adjusted. If the mobility parameter needs to be adjusted, the network device performs proper adjustment, thereby improving robustness of secondary network device mobility of the terminal device.

Abstract: A communication method and apparatus are disclosed. After receiving, from a source network device, a first message that enables a terminal device to handover from the source network device to a target network device, maintaining data transmission with the source network device; and sending a first report in response to subsequently detecting that a connection between the terminal device and the source network device fails. The first report includes first indication information used to determine whether the connection between the terminal device and the source network device fails before the terminal device accesses the target network device. In this way, the network device identifies, based on the information, a potential handover scenario that has a problem, so that a handover parameter is better adjusted or handover is more properly triggered, thereby improving a handover success rate of the terminal device.

Abstract: Embodiments of this application provide a communication method, apparatus, and system. The method includes: determining, based on area configuration information of a first cell of a network device and location information of a terminal device, a first sub-area corresponding to the terminal device, where the area configuration information indicates information about a plurality of sub-areas corresponding to the first cell, and the plurality of sub-areas include the first sub-area; and obtaining satellite ephemeris information corresponding to the first sub-area. In the foregoing solution, the sub-area is introduced, and the terminal device only needs to obtain the satellite ephemeris information corresponding to the sub-area in which the terminal device is located. This reduces an amount of satellite ephemeris information obtained by the terminal device, and therefore can reduce overheads of the terminal device.
