Codebook adaptation

A method of wireless communication performed by a receiver device, comprising:

• determining an adapted codebook for beamforming transmission based at least in part on an initial codebook and one or more spatial parameters,
• wherein the adapted codebook is associated with an adapted set of candidate beams with an adapted angular range that is different than an initial angular range of an initial set of candidate beams of the initial codebook;
• and
• receiving using at least one beam of the adapted set of candidate beams associated with the adapted angular range based at least in part on determining the adapted codebook.

A transmitter device for wireless communication, comprising:

• a memory;
• and
• one or more processors operatively coupled to the memory, the memory and the one or more processors configured to:
• determine an adapted codebook for beamforming transmission based at least in part on an initial codebook and one or more spatial parameters,
• wherein the adapted codebook is associated with an adapted set of candidate beams with an adapted angular range that is different than an initial angular range of an initial set of candidate beams of the initial codebook;
• and
• transmit using at least one beam of the adapted set of candidate beams associated with the adapted angular range based at least in part on determining the adapted codebook.
