Title:
DATA TRANSMISSION METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/082948
Kind Code:
A1
Abstract:
A data transmission method and device, wherein the method comprises: a first node generating a first data packet; the first node sending the first data packet to a second node, wherein the first data packet comprises adaptation layer information and first information or the first data packet comprises the adaptation layer information, the first information and second information; the first information is used to instruct the second node to acquire the adaptation layer information, and the second information is used to indicate the position of the adaptation layer information in the first data packet; and the first node and the second node are nodes in wireless relay communication. By means of the described method, the receiving side of a wireless return link can distinguish the mapping relationship between a logical channel and an RLC channel according to the first information, so as to determine the RLC channel mapped by the logical channel so that the data packet can be submitted to the correct RLC entity for processing.
