Title:
MAPPING METHOD, NODES, COMMUNICATION DEVICE, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2020/164176
Kind Code:
A1
Abstract:
Disclosed is a mapping method, comprising: a distributed unit in an integrated access and backhaul donor (IAB donor DU) receives a signaling message and first indication information sent by a centralized unit in the integrated access and backhaul donor (IAB donor CU), the first indication information being used for indicating the signaling type of the signaling message; and the IAB donor DU maps, according to the signaling type of the signaling message, the signaling message to a transmission channel corresponding to the signaling message and sends same to an integrated access and backhaul node (IAB node), wherein the signaling type comprising an F1AP message associated with an access terminal or an F1AP message not associated with the access terminal. In the present application, a node receives the signaling message, then maps same to the corresponding transmission channel, and sends same to the next node, so that the priority of signaling messages can be distinguished, and the quality of signaling transmission is improved.
