Abstract:
Techniques and examples of overhead reduction for linear combination codebook and feedback mechanism in mobile communications are described. A user equipment (UE) receives from a base station of a network one or more reference signals via a communication link between the UE and the base station. The UE constructs a channel state information (CSI) feedback by utilizing a correlation of channel responses in a frequency domain to reduce feedback overhead. The UE then transmits the CSI feedback to the base station.

Claim (Index 10):
The method of  claim 1 , wherein the receiving of the one or more reference signals comprises receiving the one or more reference signals from the base station, and wherein the constructing of the CSI feedback by utilizing the correlation of the channel responses in the frequency domain comprises:\n determining a channel covariance matrix; and determining an approximation of the channel covariance matrix with a unitary basis.
