1. A method, comprising:
at a user equipment (UE) in a wireless network including a first next generation NodeB (gNB) and a second gNB for communicating with the UE:
determining to transmit a first transmission (Tx) stream and a second Tx stream simultaneously to the first gNB and the second gNB for handing over communication with the UE from a first cell to a second cell, wherein the first gNB is a serving gNB in the first cell and the second gNB is a handover target gNB in the second cell; and
simultaneously transmitting within a same antenna panel of the UE the first transmission stream to the first gNB using a first polarization and the second transmission stream to the second gNB using a second polarization different from the first polarization.
