Description

Resource multiplexing indication method, device and relay node Technical Field The present application relates to the field of communications, and in particular, to a method and an apparatus for indicating resource multiplexing and a relay node. Background Currently, in a New Radio (NR) system, an access Backhaul integrated (INTEGRATED ACCESS Backhaul, IAB) may provide extended coverage for an NR cell, or may enhance capacity for an NR cell, where an access node supporting wireless access of a User Equipment (UE, also referred to as a terminal Equipment) and performing wireless Backhaul on data is referred to as an IAB node (IABN). While an access node providing a radio backhaul function for an IAB node to connect a UE to a Core Network (CN) is called a home IAB node (donor IAB node), between which a wired transmission is performed. The data of the UE is transmitted between the UE and the access node through a wireless access link (ACCESS LINK), and the data of the UE can be transmitted between the access nodes through a wireless backhaul link. In an IAB network architecture supporting a Centralized Unit (CU)/Distributed Unit (DU) split deployment, one IAB Node (IABN) includes a DU function module and a mobile terminal (Mobile Termination, MT) function module. By means of the MT function, an access node (i.e., IABN) can find an upstream access node (i.e., parent IABN, P-IABN) and establish a wireless backhaul link with the DUs of the upstream access node. After an IAB node establishes a complete backhaul link, the IAB node opens its DU function, and the DU provides cell service, i.e. the DU may provide access service for the UE. Wherein a self-backhauling loop comprises a host IAB node, all the DU function modules of the IAB node in the self-backhauling loop can be connected to a CU function module of a CU node, i.e. the host IAB node. In addition, in the IAB network architecture, the resource multiplexing manner between the MT functional module and the DU functional module may include frequency division multiplexing (Frequency Duplex Multiplexing, FDM), space division multiplexing (Spatial Duplex Multiplexing, SDM), or simultaneous Co-frequency Full Duplex (CCFD) multiplexing. However, the resource configuration and scheduling of the MT function module of the IAB node is configured by the parent IAB node through radio resource control (Radio Resource Control, RRC) signaling and downlink control information (Downlink Control Information, DCI), and the resource configuration of the IAB node DU function module is configured by the donor CU. However, when the parent IAB node schedules the MT function module resource transmission of the IAB node, the parent IAB node does not know the data to be transmitted by the DU function module of the IAB node, and the IAB next hop node (i.e., the MT function module or the UE of the IAB node) does not know Uplink (UL) data, and further does not know whether multiplexing scheduling between the MT function module and the DU function module can be implemented, which may cause insufficient use of the IAB node resource and reduced spectrum use efficiency. Therefore, how to configure or schedule resources of MT function modules and DU function modules to implement different multiplexing modes at the IAB node, so as to avoid mismatch between the MT function modules and the DU function modules, becomes a technical problem to be solved urgently. Disclosure of Invention The embodiment of the application aims to provide a resource multiplexing indication method, device and equipment, so as to solve the problems of insufficient use of IAB node resources and low spectrum use efficiency.
