Abstract: A technique for wireless communications, comprising: determining a first channel state information (CSI) based on a current receive beam; determining a second CSI based on the current receive beam; determining a correlation metric between the first CSI and the second CSI; based a comparison between the determined correlation metric and a threshold value, determining to transmit the first or second CSI in response to a CSI reference signal (CSI-RS) received from a wireless node; determining a third CSI based on a candidate receive beam and the reference signal; and selecting the candidate receive beam based on the measured third CSI.
