Patent ID: 11924863
Assignee: QUALCOMM INCORPORATED
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 7:
8. An apparatus, comprising:
a transceiver configured to:
receive, by a user equipment (UE) 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; and
a processor configured to:
select a plurality of precoders from a precoder candidate set based on the first number of bits and the common size for each subband of the set of subbands, the precoder candidate set being based on an order of a spatial direction, wherein, to select the plurality of precoders, the processor is configured to select 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
the transceiver further configured to:
transmit, by the UE 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.
