Transparent demodulation reference signal design

Abstract:

Certain aspects of the present disclosure provide procedures for transparent demodulation reference signal (DM-RS) design. According to certain aspects, a method of wireless communication by a base station (BS) is provided. The method generally includes transmitting one or more pilots based on at least one precoder used for transmitting data. The BS transmits the data based on the at least one precoder. A method by a user equipment (UE) includes receiving one or more pilots based on at least one precoder used for transmitting data on a channel. The UE estimates interference based on the one or more pilots and the UE decodes the data transmission based on the interference estimate.
