摘要:
A method for performing device-to-multidevice communication with interference suppression is provided. The method may include selecting at least one receiving user equipment for D2MD transmission, and receiving requested data rates from the selected at least one receiving user equipment. The method may further include acquiring CSI matrices and identifying interference constraints to the C-UEs sharing the same frequency band as the at least one receiving user equipment. The method then includes determining precoding matrices using the acquired CSI matrices and the identified interference constraints to the C-UEs, and performing D2MD transmission to the at least one receiving user equipment using the determined precoding matrices.
