Abstract: Methods, systems, and apparatus for communications are provided. In one aspect, a communication method including: determining, by a first communications apparatus, buffer latency information, and sending, by the first communications apparatus, the buffer latency information. The buffer latency information is determined based on a buffer latency of one or more data packets. The buffer latency indicates one of a time interval between a time point at which a data packet arrives at an access stratum (AS) and a time point at which a corresponding buffer status report (BSR) is sent, or a time interval between a time point at which a data packet arrives at an AS and a time point at which a corresponding uplink grant is received.

Abstract: The present invention relates to a beam-based multi-connection communication method, a terminal device, and a network device. The method may include the following: Based on a multi-beam connection established between a terminal and a base station, the terminal further selects a dedicated message beam from a common message range of the base station based on a measurement result of an uplink pilot, or the base station selects a dedicated message beam from a common message range of the base station based on a measurement result of a downlink pilot; and the terminal or the base station chooses to delete at least one established beam connection. By selecting and deleting a multi-beam connection between the terminal and the base station, a high-quality beam connection is maintained, and interruption of data transmission between the base station and terminal is avoided, thereby ensuring normal communication between the base station and the UE.

Abstract: This application relates to the mobile communications field, and in particular, to data transmission technologies in a wireless communications system. This application provides a data transmission method, an apparatus, and a system. In the solutions, the base station maps, according to QoS indication information of a first data packet, the first data packet to a first DRB belonging to an EPS bearer, where the EPS bearer includes N DRBs, and N is greater than or equal to 2; and the base station sends the first data packet to a terminal device by using the first DRB. One EPS bearer includes a plurality of DRBs, thereby reducing a quantity of bearers and bearer setup signaling. In addition, the plurality of DRBs can satisfy different QoS requirements.
