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 14):
The method of  claim 10 , wherein the determining of the approximation of the channel covariance matrix comprises at least one of:\n determining a low-rank matrix; determining a tri-diagonal Hermitian matrix for each subband of a plurality of subbands in the frequency domain; and determining an approximation error which accounts for interference and noise levels for each subband of the plurality of subbands in the frequency domain, wherein the CSI feedback comprises the low-rank matrix, the tri-diagonal Hermitian matrix for each subband and the approximation error for each subband.
