Abstract: A method of a base station communicating with a plurality of User Equipments (UEs), includes: identifying a number of activated UEs from among the plurality of UEs; selecting, among a plurality of feedback schemes, a feedback scheme supporting a highest data throughput at the identified number of activated UEs with reference to history information; determining (i) a number of UEs in a companion group and (ii) a codebook size, the number of UEs in the companion group and the codebook size being corresponding to the selected feedback scheme; and performing Multiple Input and Multiple Output (MIMO) communication with the activated UEs based on the determined number of UEs in the companion group and the determined codebook size.
