1. A data transmission method, applied to a first communication node, comprising:
determining remapping configuration information, wherein the remapping configuration information indicates a PC5 quality of service (QOS) flow in which re-mapping occurs, a source sidelink radio bearer (SLRB) corresponding to the PC5 QoS flow in which re-mapping occurs and a target SLRB corresponding to the PC5 QoS flow in which re-mapping occurs; and
sending the remapping configuration information to a second communication node;
wherein the data transmission method further comprises:
sending SLRB configuration information to the second communication node;
wherein the SLRB configuration information comprises at least one of: a reordering timer parameter, an out-of-order delivery indication, a reassembly timer parameter, or a status prohibition timer parameter.
