RESOURCE ALLOCATION METHOD AND DEVICE, COMMUNICATION SYSTEM AND STORAGE MEDIUM

This application discloses a resource allocation method. The method is applied to a communication system based on massive MIMO. The method includes: A donor eNodeB detects whether a target terminal exists in a donor cell, where a correlation between a wireless air interface channel of the target terminal and a wireless air interface channel of a relay node is greater than a target threshold; and if the target terminal does not exist, the donor eNodeB determines, for the relay node RN through resource spatial multiplexing, one or more beams used for data backhaul, where the one or more beams are beams formed by a massive antenna array of the donor eNodeB through air interface beamforming. Embodiments of this application further provide a corresponding resource allocation apparatus. In the technical solutions of this application, air interface resource scheduling is performed on the relay node and an ordinary terminal device in different beams based on a massive MIMO technology. In this way, an air interface resource multiplexing degree is increased, impact on the ordinary terminal device is reduced while a backhaul capability of the relay node is improved, and a capacity of an entire system is improved.
