Abstract

The invention discloses a wireless communication system node transmission state signaling indication method, a wireless communication system comprises network equipment, intermediate equipment and user equipment, and a service signal generated by the network equipment is received by the user equipment after passing through the intermediate equipment. The method comprises the following steps: a downlink control signaling comprises indication information of a transmission state of an intermediate device and an occupation time period of the intermediate device; the transmission state comprises a first state as an activated receiving state, a second state as an activated sending state and a third state as a passive transmission state; the minimum particle of the occupied time period is a symbol; the downlink control signaling comprises at least one of the following signaling: a semi-static cell dedicated control signaling, a semi-static node dedicated control signaling and a dynamic control signaling. The invention further comprises equipment and a system for realizing the method. The problem of how to control the working state of the intermediate equipment in a mobile communication system with an intermediate node facility is solved.

Description

technical field [0001] The present application relates to the technical field of mobile communication, and in particular to a method and device for controlling the transmission state of an intermediate device. Background technique [0002] The intermediate device of the present application is based on a passive transmission device that uses reflection or transmission to control the propagation of electromagnetic waves in a communication channel to improve the performance of the communication system. For example, the Intelligent Reflecting Surface (IRS) builds on the classic concept of reconfigurable reflective arrays, specifically, an IRS is a metasurface composed of a large number of tiny elements that diffusely reflect incident light in a controllable manner. Signal. [0003] When metasurfaces are applied in communication systems, the phase and other parameters of metasurfaces are controlled by the base station to better control the diffuse reflection of incident signals ...
