Abstract: In a communication configuration method, a first terminal device determines a first message that comprises first information and second information. The first information comprises radio link control (RLC) bearer configuration information of a first sidelink, and the second information comprises RLC bearer configuration information of a second sidelink. The first sidelink is between the first terminal device and a third terminal device, and the second sidelink is between the third terminal device and a second terminal device. The first terminal device then sends the first message to the third terminal device.

Abstract: Embodiments of this application provide a data transmission method and an apparatus. When more than two radio link control RLC entities are configured for one radio bearer RB, a secondary network device receives indication information from a master network device. The secondary network device may determine, based on the indication information, a master RLC entity associated with the radio bearer, to indicate, to a terminal device, RLC entities that need to be activated and deactivated.

Abstract: Embodiments of this application provide a communication method and apparatus. The method includes: A first device (for example, a terminal device or a network device) determines that a first data frame is lost. The first device discards a first data packet received from an upper layer, where the first data packet is a part of or all data packets in a second data frame, the second data frame is located after the first data frame, and the second data frame is associated with the first data frame. According to the method disclosed in this application, a data frame transmission failure is identified, and proactive discarding of a data packet in a subsequent data frame associated with the lost data frame is triggered, to avoid a waste of air interface resources and transmission resources, reduce execution of unnecessary decoding operations, and reduce power consumption of the device while improving resource utilization.

Abstract: A terminal device receives first configuration information and second configuration information from an access network device, where the first configuration information is used to configure a first transmission occasion corresponding to a first SSB, the second configuration information is used to configure M second transmission occasions corresponding to the first transmission occasion, and the M second transmission occasions and the first transmission occasion correspond to a same SSB. Further, the terminal device may initially transmit, on the first transmission occasion, a preamble corresponding to the first SSB, and retransmit the preamble on each of the M second transmission occasions, where M is a positive integer.
