Activation or deactivation of multiple downlink (DL) or uplink (UL) positioning reference signals (PRS) with a single MAC-CE command

Abstract

A user equipment (UE) receives configurations for multiple downlink (DL) positioning reference signals (PRS), multiple uplink (UL) PRS, or a combination thereof. A single Medium Access Control-Control Element (MAC-CE) block from a serving base station is provided that activates or deactivates in the UE the transmissions of the multiple UL PRS; reception of the multiple DL PRS, or a combination thereof, and in response the UE activates or deactivates the transmission and/or reception of the multiple UL PRS and/or DL PRS. The MAC-CE block, for example, may identify multiple UL PRS resource sets, each of which includes at least one PRS resource, for activation or deactivation. The MAC-CE block may additionally or alternatively, identify multiple DL PRS resources, multiple DL PRS resource sets, or multiple DL PRS frequency layers for activation or deactivation.
