Abstract
Methods, systems, and devices for wireless communications are described. A communication device, such as a user equipment (UE) and a base station, for example, an eNodeB (eNB), a next-generation NodeB or a giga-NodeB (either of which may be referred to as a gNB) may support techniques for transformation of analog beamforming codebooks. The communication device may modify an analog beamforming codebook based on a covariance matrix associated with interference and noise in a wireless communication system. For example, the communication device may rotate the analog beamforming codebook based on the estimated covariance matrix, or scale one or more beam weights associated with the analog beamforming codebook based on the estimated covariance matrix, or both. The communication device may thereby perform wireless communication with another communication device in the wireless communication system using the modified analog beamforming codebook.
