Embodiment Construction

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0038] Before the method of the specific embodiment of the present invention is described in detail, a brief description of the IAB (Integrated Access and Backhaul, integrated access and backhaul) network is given first, so as to better understand the specific embodiment of the present invention.

[0039] In an IAB network, an IAB node includes a DU (Distributed Unit, distributed unit) functional part and an MT (Mobile Termination, mobile terminal) func...

Abstract

The invention provides a transmission method and network equipment. When applied to a first IAB node, the transmission method comprises the following steps: sending a first control PDU to a second IAB node, the second IAB node being a father node of the first IAB node, the first control PDU comprising a first field; the first field being used for indicating the BH RLC channel or the BH RLC channel group or the BH RLC channel interval which is congested. According to the technical scheme provided by the invention, the problems of data packet loss and transmission delay caused by the fact that the parent node cannot be effectively notified of the congestion condition of the child node in the existing IAB network are solved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a transmission method and network equipment. Background technique [0002] In the Integrated Access and Backhaul (IAB) network, for the intermediate (Intermediate) IAB nodes in the multi-hop topology, not only the current communication status but also the current communication status must be considered when transmitting data. The transmission coordination relationship of different nodes in the IAB network, otherwise it is easy to cause data congestion. [0003] For example, if figure 2 As shown, the IAB donor (donor) node can send downlink data to the user terminal (User Equipment, UE) through the IAB node A, the IAB node B, and the IAB node C. If the backhaul link between the IAB node B and the IAB node C Encountered link congestion, then IAB node B should send flow control information (Flow Control Message) to its upstream node (parent node), that is, IAB node ...
