Abstract:
In order to recognize a relatively accurate channel state of each UE, a channel of the UE is reconfigured based on channel phase information and channel quality information reported from the UE to obtain a channel matrix of the UE. Besides, a channel of the UE is reconfigured based on channel phase information and channel quality information reported from the UE to obtain a channel matrix of the UE, a precoding matrix of the UE is determined based on the channel matrix of the UE, and precoding is performed on data to transmit to the UE, using the precoding matrix.
