[0027] The present invention will be described in detail below in conjunction with the accompanying drawings and simulation examples.
[0028] The present invention proposes a multi-antenna multicast transmission method for a symbiotic communication system based on an intelligent reflective surface: the system composition structure is as follows figure 1 As shown, it consists of a base station configured with M antennas, an IoT receiver configured with Q antennas, a smart reflective surface containing N passive reflective units and an IRS controller connected to it, and K single-antenna main receivers composition. Among them, K main receivers are divided into G groups according to different information requirements, The main receivers in the same group request the same information at the same time, and each main receiver can only belong to one group, that is, the main receiver Let M≥1, Q≥1, K≥1, 1≤G≤K.
[0029]The basic working principle of the multi-antenna multicast t...
