Embodiment Construction

[0088] In the current 5G standard, considering the small coverage of the high-frequency band, in order to ensure the coverage performance of the network, multi-hop networking can be used in the IAB network. Considering the requirements of service transmission reliability, IAB nodes can be enabled to support dual connectivity (DC) or multi-connectivity (multi-connectivity) to deal with abnormal conditions that may occur on the backhaul link, such as link failure or blockage / Congestion (blockage) or load fluctuations and other abnormalities to improve transmission reliability.

[0089] Since the IAB network supports multi-hop and multi-connection networking, multiple transmission paths may exist between a terminal device (for example, user equipment (UE)) and an IAB donor node (IAB donor). Each transmission path includes multiple nodes, and the multiple nodes may include a UE, one or more IAB nodes, and an IAB donor. If the IAB donor is a form in which the centralized unit (C...

Abstract

The embodiment of the invention provides a flow control method and device, relates to the field of communication, and can avoid a packet loss problem caused by link congestion or deterioration. The method comprises the steps: a first IAB node receiving first information from a second IAB node, the first information being used for indicating cache states of uplink data respectively corresponding to N BAP routing identifiers on the second IAB node, and / or cache states of uplink data respectively corresponding to M RLC CHs between the second IAB node and the first IAB node, wherein the first IAB node is a child node of the second IAB node, and N and M are integers greater than or equal to 1; and the first IAB node performs uplink flow control according to the first information. The embodiment of the invention is applied to the IAB network.

Description

technical field [0001] The present application relates to the communication field, and in particular to a flow control method and device. Background technique [0002] In order to meet the ultra-high capacity requirements in the fifth generation (5G) system, high-frequency carriers have attracted much attention because they have more abundant frequency resources than low-frequency ones, and have been selected as the main working frequency band of 5G systems. The propagation characteristics of high-frequency carriers are poor, the attenuation is serious due to occlusion, and the coverage area is not wide. Therefore, a large number of densely deployed small stations are required in hotspot areas. Correspondingly, the cost of providing optical fiber backhaul for these densely deployed small stations is very high. Deployment is difficult. In order to solve the above problems, the integrated access and backhaul (IAB) technology of the wireless relay is introduced, and its access...
