Techniques for transformation of analog beamforming codebooks

A first apparatus for wireless communication in a wireless communication system, comprising:

• one or more processors,
• one or more memories coupled with the one or more processors;
• and
• instructions stored in the one or more memories and executable by the one or more processors to cause the first apparatus to:
• modify, at the first apparatus and in accordance with a transform operation, an analog beamforming codebook based at least in part on a covariance matrix associated with interference and noise in the wireless communication system, wherein the covariance matrix is a single covariance matrix that is estimated at the first apparatus based at least in part on one or more interference and noise measurements made at the first apparatus;
• determine an uplink directional beam pair or a downlink directional beam pair based at least in part on a computational complexity and a thermal overhead associated with the transform operation;
• and
• transmit, from the first apparatus, one or more wireless communications to perform the wireless communication with a second apparatus in the wireless communication system via the uplink directional beam pair or the downlink directional beam pair using the modified analog beamforming codebook.
