Patent ID: 8792896

Claim:
A method of communicating with a selected user equipment terminal (UE) in a first cell served by a base station and a remote radio head, the method comprising: forming a list of non-targeted UEs including other UEs in the first cell, and cell edge UEs in a neighboring cell that borders the first cell that are located near a border of the first cell and the neighboring cell, the list including geographic locations and signal to interference plus noise ratios (SINRs) of the non-targeted UEs; generating a list of candidate precoding matrices that can be used to communicate with the selected UE from the base station and/or from the remote radio head; generating a list of available preceding matrices by discarding from the list of candidate preceding matrices those preceding matrices that may cause interference to at least one non-targeted UE; selecting a preceding matrix from the list of available preceding matrices; and communicating with the selected UE using the selected preceding matrix.
