1. A method of wireless communications at a user equipment (UE) comprising:
receiving, from a base station, a plurality of multi-port reference signals, wherein each of the plurality of multi-port reference signals is received at a first port associated with a first polarization using a first directional beam of the UE and at a second port associated with a second polarization using a second directional beam of the UE;
determining an estimate of spectral efficiency for each multi-port reference signal of the plurality of multi-port reference signals based at least in part on the receiving;
selecting a beam pair for communications with the base station based at least in part on the determined estimate of spectral efficiency for each multi-port reference signal; and
transmitting an indication of the selected beam pair to the base station.
