Abstract
Aspects of the present disclosure provide techniques and apparatus for enhancing performance by selectively applying averaging to CSI reporting processes. According to certain aspects, a base station (e.g., an eNB) with knowledge of traffic patterns of potentially interfering transmitters may signal a UE how (or whether) to apply averaging, for example, when reporting CSI based on interference measurement resources (IMR).
Claims30
A method for wireless communications by a user equipment (UE), comprising:
- receiving, from a base station, an indication of a type of averaging to be applied for channel state information (CSI) reporting;
- measuring reference signals received in one or more subframes;
- generating a CSI report based on the measurements and the indicated type of averaging;
- and
- sending the CSI report.
A method for wireless communications by a base station (BS), comprising:
- transmitting, to a user equipment (UE), an indication of a type of averaging to be applied for channel state information (CSI) reporting;
- and
- receiving, from the UE, a CSI report generated based on reference signal measurements and the indicated type of averaging.
An apparatus for wireless communications by a user equipment (UE), comprising:
- means for receiving, from a base station, an indication of a type of averaging to be applied for channel state information (CSI) reporting;
- means for measuring reference signals received in one or more subframes;
- means for generating a CSI report based on the measurements and the indicated type of averaging;
- and
- means for sending the CSI report.
