Abstract:
The described technology is generally directed towards reducing the complexity for finding the precoding matrix index/rank information channel state information in New Radio wireless systems. Described is using the beam characteristics of X1 (wideband component index) and X2 (subband component index) such that a user equipment first determines a best chosen X2 for only one X1 index. Thereafter, the user equipment uses the chosen index of X2 for the other X1 indices, thereby reducing the complexity of the precoding matrix index/rank information search by reducing the search space in the codebook, which reduces the number of computations at the user equipment side without significantly impacting the performance.

Claim (Index 1):
A method, comprising:\n determining, by a user equipment comprising a processor, respective first link quality metric values for combinations of a starting wideband-based index of a group of wideband-based indices and subband-based indices of a group of subband-based indices; choosing, by the user equipment, a subband-based index from the group of subband based indices that has an associated first link quality metric value that satisfies a criterion, the choosing resulting in a chosen subband-based index; determining, by the user equipment, respective second link quality metric values for combinations of the chosen subband-based index and wideband-based indices of the group of wideband-based indices other than the starting wideband-based index; and choosing, by the user equipment, a precoding matrix indicator based on the respective second link quality metric values and the associated first link quality metric value for the combination of the chosen subband-based index and the starting wideband-based index.
