Dual port SSB for multi-Rx beam selection

A method for a user equipment (UE), comprising:

• receiving, from a first transmission reception point (TRP), a first synchronization signal block (SSB) with a first polarization and a second SSB with a second polarization different than the first polarization;
• determining a channel matrix based on the first SSB and the second SSB;
• identifying, based on the channel matrix and a linear minimum mean square error (LMMSE) criterion, one or more optimal receive (Rx) beams for multiple-input multiple-output (MIMO) communication;
• and
• receiving data using the one or more optimal Rx beams.

A user equipment (UE), comprising:

• radio frequency (RF) circuitry;
• and
• a processor coupled to the RF circuitry and configured to execute instructions stored in a memory to cause the UE to:
• receive, from a first transmission reception point (TRP), a first synchronization signal block (SSB) with a first polarization and a second SSB with a second polarization different than the first polarization;
• receive, from a second TRP, a third SSB with a third polarization and a fourth SSB with a fourth polarization different than the third polarization;
• identify one or more optimal receive (Rx) beams for multiple-input multiple-output (MIMO) communication, based on the first SSB, the second SSB, the third SSB, and the fourth SSB;
• and
• receive a MIMO transmission using the one or more optimal Rx beams.
