Some aspects relate to apparatuses and methods for selecting a receiving beam based on hybrid channel based beamforming and codebook based beamforming. A user equipment (UE) can determine, based on a first measurement related to signal to noise ratio (SNR) and predetermined threshold values, whether the UE is in a low SNR state. If the UE is in a low SRN state, the UE can derive an estimated channel covariance matrix Rfor channels at a set of antenna elements of the UE based on channel based bearmforming (CHBF). Afterwards, a set of test bears {0, . . . N−1} is selected based on the channel covariance matrix R, and a set of codebook measurement beams is further selected based on the set of test beams. A receiving beam is selected based on a set of measurements performed on the set of codebook measurement beams at the measurement opportunity for codebook based beamforming (CBBF).
