Abstract:
Various devices and methods are provided that use enhanced downlink demodulation reference signals (DMRS) to facilitate inter-cell interference cancellation and suppression. Coordinated configuration of DMRS port assignments for transmission from cells in a group of neighboring cells is provided. Each cell's physical cell identification (PCID) is mapped with its corresponding assigned antenna port(s).
