Problems solved by technology

In the wireless relay scenario, multiple terminals will be connected to one IAB node. Therefore, when the IAB node transmits the radio bearers of multiple terminals, if each radio bearer is carried on a separate logical channel for transmission, then The fixed number of logical channels in the prior art is not enough to carry the radio bearers of multiple terminals

Abstract

The invention discloses a wireless backhaul processing method and a communication device. The method is characterized by configuring the number of logical channels of a wireless backhaul device through first information sent by a host base station, and since the host base station can determine the number of logic channels supported by each wireless backhaul device according to at least one of thetopology information of the communication system and the capability information of the wireless backhaul devices, the logical channels of the wireless backhaul device can bear a plurality of radio bearers of a plurality of terminal side devices to enable one-to-one mapping from the radio bearers of each terminal device to the logical channels in the wireless backhaul device to be realized.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a wireless backhaul processing method and a communication device. Background technique [0002] In order to improve the network coverage of the communication system, mobile communication technology introduces wireless relay technology. The general idea is that the donor base station (donor gNodeB, DgNB) is connected to the core network through a wired link (for example, in 5G system core network (5G core, 5GC)), and then add a relay node (relay node, RN) or an integrated access and backhaul node (IAB node) between the DgNB and the terminal, through the IAB The access link (access link, AL) of the node provides wireless access services for the terminal, and is connected to the DgNB through the backhaul link (BL) of the IAB node to transmit the service data of the terminal. [0003] In the backhaul link, the radio bearer generated by the terminal (for exampl...
