Assignee: QUALCOMM INCORPORATED
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 22:
23. An apparatus, comprising:
means for receiving, from a base station (BS), a subband precoding configuration, the subband precoding configuration including a first number of bits and an indication of a common size for each subband of a set of subbands;
means for selecting, based on the first number of bits and the common size for each subband of the set of subbands, a plurality of precoders from a precoder candidate set, wherein the precoder candidate set is based on an order of a spatial direction, wherein the selecting the plurality of precoders includes selecting at least one first precoder based on a second number of bits and selecting at least one second precoder based on a third number of bits different than the second number of bits; and
means for transmitting, to the BS in the set of subbands, a communication signal generated by applying a respective precoder of the selected plurality of precoders to each subband of the set of subbands,
wherein the communication signal includes, based on the plurality of precoders, signals in a plurality of spatial directions with a plurality of beam width angles.
