Abstract: Embodiments of this disclosure provide a data transmission method and a terminal device. The data transmission method includes receiving first uplink resource allocation information sent by a network side device. The first uplink resource allocation information is used to indicate a first uplink resource. The data transmission method further includes sending a first medium access control protocol data unit (MAC PDU) over the first uplink resource. The first MAC PDU is a PDU obtained through packet assembly on target data based on the first uplink resource. The target data includes at least data content of a second MAC PDU. The second MAC PDU is a previously generated MAC.

Abstract: This application provides a data packet bearer path determining method, an information sending method, and a device. The data packet bearer path determining method includes determining, from a plurality of configuration paths of a target radio bearer (RB) or a plurality of active paths in the plurality of configuration paths, a bearer path of a Packet Data Convergence Protocol (PDCP) non-duplicated data packet corresponding to the target RB, where the target RB is an RB configured with a PDCP data duplication function.
