  • Publication number: 20230300776
    Abstract: A user equipment (UE) uses downlink positioning reference signals (PRS) beams for position measurements. The PRS beams may be transmitted using beamforming and transmitted in a beam-sweeping manner. The UE receives assistance data that includes PRS configuration information including the azimuth and elevation angles and beam width information for each PRS beam. The beam width information may include the beam width, bore sight direction uncertainty, beam width uncertainty, and side lobe/back lobe beam information. The UE may select or adapt the receive (Rx) antennas based on the beam width information to reduce power consumption, for example, by reducing the number of Rx antennas used to receive wide PRS beams, and selecting a larger number of Rx antennas when the PRS beams are narrow.

  • Patent number: 11758511
    Abstract: A muting configuration for downlink positioning reference signals (PRS) is based on the slot type in which the PRS is transmitted. A slot type muting configuration mutes PRS if the PRS are transmitted in a full duplex slot, such as an in-band full duplex slot. If the PRS are transmitted in a sub-band full duplex slot, the PRS may be muted depending on whether the base station is capable of self-interference cancellation. The slot type muting configuration does not mute the PRS transmission in a half-duplex slot. The slot type muting configuration may be dynamic and may be provided to a user equipment (UE) in lower layer signaling to improve latency. The slot type muting configuration may be combined with other types of muting configurations, such as inter-instance muting, intra-instance muting, and intra-slot muting, e.g., using a logic function to combine the configurations.
