Patent ID: 8917690

Claim:
A method comprising: allocating a first subset of resource elements (REs) of a physical resource block (PRB) to a mobile terminal and associating one or more first demodulation reference symbols (DM-RS) ports therewith, wherein the first subset of REs and the one or more first DM-RS ports have common interference characteristics, wherein in an instance in which the one or more first DM-RS ports are non-overlapping with respect to one or more second DM-RS ports associated with a second subset of REs of the PRB, the associated first subset of REs also are non-overlapping with respect to the second subset of REs; multiplexing the first subset of REs with the second subset of REs in accordance with frequency division multiplexing (FDM), time division multiplexing (TDM), code division multiplexing (CDM) or space division multiplexing (SDM) and multiplexing the one or more first DM-RS ports with the one or more second DM-RS ports in accordance with FDM, TDM, CDM or SDM; and causing transmission of the PRB for reception by the mobile terminal.
