1. A method of wireless communication performed by a transmitter 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
wherein a number of candidate beams in the adapted set of candidate beams is smaller than a number of candidate beams in the initial set of candidate beams; and
transmitting information using at least one beam of the adapted set of candidate beams based at least in part on determining the adapted codebook.
