Abstract: A resource allocation 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 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.
