Claim 0:
1. A method for communication in a communication network, said communication network comprising a plurality of base stations (BSs) spatially distributed in a geographic region, at least one user equipment device (UE) being connected to a BS, the method comprising:
signaling, by the BS, at least one antenna port number from a plurality of antenna port numbers to the at least one UE, for reference signal (RS) transmission;
receiving, by the BS, a data and a RS corresponding to the at least one UE, the data and the RS are being received on one or more receive antennas of the at least one BS, wherein the RS comprises occupied RS subcarriers and null subcarriers, a location of occupied RS subcarriers and null subcarrier positions are selected according to the signaled at least one antenna port;
estimating, by the BS, one or more channel parameters and interference plus noise parameters using the occupied subcarriers associated with the received RS, and interference plus noise parameters using the null subcarriers, wherein said channel parameters and said interference plus noise parameters are associated with one or more receive antennas of the BS; and
equalizing, by the BS, the received data on the one or more receive antennas using the measured channel parameters and the interference plus noise parameters corresponding to the at least one signaled port for interference rejection and data detection.
