摘要： This application relates to the field of wireless communications technologies, and in particular, to a communication method, apparatus, and system. This application provides a communication method. The method includes: a user equipment sends a first message to a secondary base station, where the first message is used to indicate that an exception occurs on a connection between the user equipment and a master base station; and the user equipment receives a second message sent by the secondary base station, where the second message is used to indicate whether to recover the connection to the master base station. This aims to quickly recover the connection between the user equipment and the master base station through interaction between the user equipment and the secondary base station, thereby reducing interruptions of data transmission and/or signaling transmission, and further improving system performance and user experience.

摘要： This application provides a sidelink communication method and a related apparatus. The method may include: A first terminal device determines first indication information, and sends first SCI including the first indication information to a second terminal device, where the first indication information is used to determine not to perform LBT on PSFCH resources; and when receiving the first SCI, the second terminal device determines, according to the first indication information included in the first SCI, not to perform LBT on the PSFCH resources. This application may be applied to a scenario in which SL communication is performed by using an unlicensed spectrum, to reduce power consumption of the second terminal device and improve SL communication quality.

摘要： The present disclosure relates to mode switching methods, data flow splitting methods, and apparatus. One example mode switching method includes generating, by a first device, first indication information, where a packet data control protocol (PDCP) entity in the first device is connected to at least two radio link control (RLC) entities in a second device, and sending, by the first device, the first indication information to the second device, where the first indication information is used to indicate that transmission between a first RLC entity in the at least two RLC entities and the PDCP entity in the first device is to be canceled. The second device stops the transmission between the first RLC entity and the PDCP entity based on the first indication information.

摘要： Example configuration methods and apparatus are described. An example communications system includes a master node and a secondary node that jointly provide a service for a terminal. One example method includes generating configuration information for a signaling radio bearer (SRB) by the secondary node, where the SRB is used to transmit a radio resource control (RRC) message between the secondary node and the terminal. The secondary node sends the configuration information for the SRB to the master node, so that the configuration information for the SRB is sent to the terminal through the master node. The secondary node receives a result of configuring the SRB by the terminal by using the configuration information for the SRB. In this way, the SRB can be established on the secondary node, and used for RRC message transmission between the secondary node and the terminal.

摘要： The present disclosure relates to communication methods in multi-rat dual connectivity, apparatus, and systems. In one example method, when a packet data convergence protocol sequence number (PDCP SN) length of a bearer is changed, a secondary node (SN) sends a PDCP SN length change indication to a master node (MN).

摘要： Methods and apparatus are provided for data transmission. A remote device determines a sidelink multicast identifier identifying multicast between the remote device and a plurality of relay devices and sends uplink data to the plurality of relay devices in a multicast manner based on the sidelink multicast identifier. The uplink data is data sent by the remote device to a radio access network device. The remote device determines the sidelink multicast identifier, and sends the sidelink multicast identifier to the relay device to transmit the uplink data to the radio access network device based on multicast communication to improve uplink data transmission efficiency.

摘要： Embodiments of this application provide a communication method and apparatus. The method includes: A first terminal performs integrity protection verification on a received RRC message; and when the integrity protection verification fails, an RRC layer of the first terminal sends a first indication and an identifier of a second terminal to an application layer of the first terminal, where the first indication and the identifier of the second terminal are used by the application layer to disconnect a unicast connection between the first terminal and the second terminal. Based on this solution, when the integrity protection verification performed by the first terminal on the received message fails, the RRC layer of the first terminal may report the first indication and the identifier of the second terminal to the application layer, to trigger the application layer to disconnect the unicast connection between the first terminal and the second terminal.
