ANGLE CALIBRATION FOR CROSS-LINK INTERFERENCE ANGLE-OF-ARRIVAL ESTIMATION - A simplified explanation of the abstract
This abstract first appeared for US patent application 18040394 titled 'ANGLE CALIBRATION FOR CROSS-LINK INTERFERENCE ANGLE-OF-ARRIVAL ESTIMATION
Simplified Explanation
The patent application describes techniques for improving the estimation of the angle-of-arrival (AoA) of uplink signals in a wireless communication system.
- Victim user equipment (UE) is configured with cross-link interference (CLI) resources to measure interference from other UEs.
- The victim UE uses these CLI opportunities to estimate the AoAs of the uplink signals from the interfering UEs.
- By estimating the AoAs, the location estimation of the victim UE can be enhanced.
- This technique allows for more accurate positioning of UEs in a wireless communication system.
Original Abstract Submitted
Techniques for enabling a cross-link interference (CLI) based uplink (UL) angle-of-arrival (AoA) estimations are disclosed. A victim user equipment (UE) may be configured with CLI resources to measure CLIs from one or more aggressor UEs. The victim UE may take the CLI opportunities also to estimate the AoAs of the UL signals from the aggressor UEs. In this way, UE's location estimation may be enhanced.
