Abstract
Certain aspects of the present disclosure provide techniques for channel state information (CSI) reporting with frequency domain (FD) compression. More particularly, aspects of the present disclosure provide for codebook subset restriction (CBSR) on per spatial domain (SD) basis amplitude.
Claims20
A method for wireless communications by a user equipment (UE), comprising:
- receiving a channel state information (CSI) request, from a base station, triggering a CSI report that is based on a plurality of linear combination coefficients;
- receiving a configuration which restricts, for each spatial domain (SD) basis, a maximum average amplitude of the plurality of linear combination coefficients for an associated SD basis;
- and
- sending the CSI report based on the plurality of linear combination coefficients generated in accordance with the configuration.
