COEXISTENCE BETWEEN DOWNLINK (DL) POSITIONING REFERENCE SIGNAL (PRS) AND UPLINK (UL) TRANSMISSION IN A FULL DUPLEX USER EQUIPMENT (UE)

Abstract:

A method of wireless communications by a user equipment (UE) determines whether a downlink positioning reference signal (PRS) overlaps in time with an uplink transmission within a full duplex slot. The method adjusts the uplink transmission to address the overlap. The adjusting can use an uplink grant to achieve a gap between the PRS and the uplink transmission. The adjusting can puncture a number of resource elements assigned for the uplink transmission. The resource elements are positioned adjacent to the PRS. The adjusting can reduce transmit power. The method can include receiving a priority order for the PRS and multiple uplink transmission types. In this case, the adjusting comprises dropping the uplink transmission in accordance with the priority order.
