BACKGROUND

CoMP technology has been standardized to allow the user equipment (UE) to receive signals from multiple transmission points (TPs) in different usage scenarios. The different sce narios include: 1) a homogeneous network with intra-site CoMP 2) a homogeneous network with high transmit (Tx) power remote radio heads (RRHs), 3) a heterogeneous net work with low-power RRHs within the macro cell coverage where the transmission/reception points created by the RRHs have different cell identifiers (IDs) from the macro cell, and 4) a heterogeneous network with low power RRHs within the macro cell coverage where the transmission/reception points created by the RRHs have the same cell IDs as the macro cell.
