Abstract:
Certain aspects of the present disclosure relate to methods and apparatus relating to precoding reference signals for uplink transmissions with downlink interference information. In certain aspects, a method, performed by a user equipment (UE) comprises receiving, from a base station, one or more signals for use in estimating channel quality for a downlink between the base station and the UE. The method also includes determining a first frequency resource and a second frequency resource from a frequency band allocated for transmitting a reference signal (RS). The method further includes computing a first downlink channel quality estimate for the first frequency resource using the one or more signals, transmitting a first RS precoded using the first downlink channel quality estimate, computing a second downlink channel quality estimate for the second frequency resource using the one or more signals and transmitting a second RS precoded using the second downlink channel quality estimate.
