View source for METHODS AND APPARATUS FOR RECEIVE ANTENNA ADAPTATION FOR USER EQUIPMENT POWER SAVING: abstract simplified (18005930)

The abstract describes a system where a user device (UE) uses special signals called downlink positioning reference signals (PRS) beams to determine its position. These PRS beams are transmitted in a specific way called beamforming, where the signals are focused in a particular direction. The UE receives assistance data that provides information about the configuration of these PRS beams, such as their angles and width. This information helps the UE in selecting or adjusting its receive antennas to optimize power consumption. For example, if the PRS beams are wide, the UE can use fewer antennas to receive them, saving power. On the other hand, if the PRS beams are narrow, the UE can use more antennas to improve reception.
