Abstract:
Systems and methods are disclosed for providing location-based codebook subset restriction. In some embodiments, location-based codebook subset restriction is provided in such a manner as to mitigate co-channel interference from a macro base station to User Equipment devices (UEs) in a cell range expansion zone of a Low Power Node (LPN) within a coverage area of the macro base station. In this manner, performance of the UEs in the cell range expansion zone is improved.
