Abstract:
1. A method within a wireless communication network, the method comprising: selecting, by a user equipment, a preferred interference precoding matrix from among a plurality of candidate precoding matrices included in a codebook, wherein the preferred interference precoding matrix is associated with a direction, such that when a communication node transmits a signal in the direction associated with the preferred interference precoding matrix, an interference power component of the transmitted signal received by the user equipment is low, the interference power component being interference from signals transmitted within the wireless communication network; and transmitting, by the user equipment to the communication node, a preferred interference precoding matrix index (PMI) corresponding to the preferred interference precoding matrix included in the codebook, the preferred interference PMI being transmitted by the user equipment to the communication node to notify the communication node of the preferred interference precoding matrix of the user equipment for receiving data signals with a low level of interference.
