Abstract: Embodiments of the present invention provide a method and device for demodulating data. The method includes: determining a number of reliable bits of each path of data in M paths of data and a modulation manner used to demodulate the reliable bits of each path of data, where M is a positive integer; demodulating the reliable bits of each path of data according to the modulation manner used to demodulate the reliable bits of each path of data; and demodulating residual bits in each path of data except the reliable bits according to a maximal likelihood ML algorithm. Compared with the prior art, it is unnecessary to demodulate all bits of each path of data according to the ML algorithm, thereby lowering the complexity of demodulation by using the ML algorithm.

Abstract: This application relates to a communication method and device. A remote terminal device receives a first data packet from a relay terminal device by using an SRB1. The first data packet includes a first message and an SRAP header. The remote terminal device removes the SRAP header via an SRAP entity to obtain configuration information. The SRAP entity is determined before the SRAP header is removed. The remote terminal device configures the SRAP entity based on the configuration information. The remote terminal device may predetermine the SRAP entity.

Abstract: An access network device determines to add, for a remote terminal device, a direct path for connecting a first cell. The remote terminal device is connected to a second cell through an indirect path. The access network device sends an RRC reconfiguration message to indicate the remote terminal device to switch to the direct path. The RRC reconfiguration message further indicate not to release the indirect path. When being indicated to switch to the direct path, the remote terminal device may further be indicated not to release the indirect path.

Abstract: 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.

Abstract: 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.
