Abstract: Exemplary embodiments include methods performed by a user equipment (UE). The methods include transmitting two transmission (Tx) streams simultaneously, wherein the two Tx streams are transmitted by two distinct Tx polarization circuitries within a same UE antenna panel circuitry as two Tx polarizations. The methods also include identifying a first signal, identifying a second signal, transmitting the first signal in a first direction using a first polarization of an antenna panel and transmitting the second signal in a second direction using a second polarization of the antenna panel.

Abstract: A user equipment (UE) in a wireless network including a first next generation NodeB (gNB) and a second gNB for communicating with the UE performs operations. The operations include 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.
