Abstract (en)
[origin: WO2017165450A1] Techniques for orthogonal multiplexing Demodulation Reference Signals (DM-RS) can include transmitting the DM-RS based on a resource allocation and transmitting the data on a subset. Alternatively, the DM-RSs can be transmitted on a subset of subcarriers in the resource allocation. In addition, the DM-RSs of a given UE can be combined utilizing Frequency Division Multiplexing (FDM) with DM-RS of other UEs. The DM-RS of the given UE can also be combined utilizing a cross-subframe orthogonal complimentary code (OCC) of a third or higher order with the DM-RSs of other UEs.
