Embodiment Construction

[0034] In an IAB scenario, how to effectively allocate resources between a backhaul link (Backhaul Link, BH Link) and an access link (AccessLink, AC Link) is an important issue. At present, it mainly includes time division multiplexing (TDM, Time Division Multiplexing) (see Figure 1a , 1b , 1c and 1d), Space Division Multiplexing / Frequency Division Multiplexing (SpaceDivision Multiplexing / Frequency Division Multiplexing, SDM / FDM) (see Figure 2a and Figure 2b ) in three ways.

[0035] From Figure 1a to Figure 1d It can be seen that due to the time division multiplexing mode, the BH link and the AC link cannot be performed simultaneously in the time domain. From Figure 2a and Figure 2b It can be seen that due to the use of space division multiplexing / frequency division multiplexing, the BH link and the AC link cannot be performed simultaneously in the time domain.

[0036] For each IAB node, it may support full-duplex, that is, at the same time, the IAB node can both...

Abstract

The embodiment of the invention discloses a resource allocation method and device based on IAB node capability, a relay node and a storage medium. The method comprises the steps that resource allocation is carried out according to the IAB-node capacity, and the IAB-node capacity is used for representing whether the IAB-node is in a full duplex mode or a half duplex mode.

Description

technical field [0001] Embodiments of the present invention relate to, but are not limited to, communication technologies, and in particular, relate to a method, device, node, and storage medium for resource allocation based on IAB node capabilities. Background technique [0002] In the fifth generation (5 th Generation (5G) system, in order to solve the millimeter wave coverage problem, Integrated Access and Backhaul (IAB) came into being. The application of multi-hop relay is considered in the IAB technology. In an IAB scenario, how to effectively allocate resources between a backhaul link (Backhaul Link, BH Link) and an access link (Access Link, ACLink) is an important issue. In the current IAB AC and BH resource allocation, how to perform resource allocation according to the capability of the IAB node (node) is not given. Contents of the invention [0003] In view of this, the embodiments of the present invention provide a method, device, node, and storage medium f...
