Abstract
Methods of communicating with a selected user equipment terminal (UE) in a first cell served by a base station and a remote radio head include 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, 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 precoding matrices by discarding from the list of candidate precoding matrices those precoding matrices that may cause interference to at least one non-targeted UE, selecting a precoding matrix from the list of available precoding matrices, and communicating with the selected UE using the selected precoding matrix.
