INTRA-CELL UE-TO-UE CROSS LINK INTERFERENCE MANAGEMENT AT FULL-DUPLEX OPERATION - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240223343 titled 'INTRA-CELL UE-TO-UE CROSS LINK INTERFERENCE MANAGEMENT AT FULL-DUPLEX OPERATION

The patent application discusses methods and systems for managing and measuring intra-cell cross-link interference (CLI) in a full-duplex FDD base station serving a UE.

• Signaling is used to inform a victim UE about resources to measure CLI levels from aggressor UEs.
• Resources for CLI measurement are not scheduled for the victim UE's downlink reception but are used by aggressor UEs for uplink traffic or transmitting reference signals.
• Victim UE can report CLI measurements to the base station for adjusting downlink resource scheduling.
• Signaling from the base station may indicate potential CLI impact on scheduled downlink symbols to the victim UE.

Potential Applications: - Wireless communication networks - Cellular network optimization - Interference management in base stations

Problems Solved: - Managing intra-cell cross-link interference - Optimizing resource allocation in full-duplex FDD systems

Benefits: - Improved network performance - Enhanced user experience - Efficient resource utilization

Commercial Applications: Title: "Enhanced Intra-Cell Cross-Link Interference Management in Wireless Networks" This technology can be applied in telecommunications companies to optimize network performance and enhance user experience, leading to increased customer satisfaction and retention.

Questions about Intra-Cell Cross-Link Interference Management: 1. How does the signaling from the base station help in managing CLI levels for victim UEs? 2. What are the potential implications of adjusting downlink resource scheduling based on victim UE reports?

Frequently Updated Research: Stay updated on the latest advancements in intra-cell cross-link interference management in wireless communication networks to ensure optimal network performance and user experience.

Original Abstract Submitted

methods and systems are disclosed for a ue to manage and measure intra-cell cross link interference (cli) when served by a base station operating in full-duplex fdd. the signaling may indicate to a victim ue resources to measure to determine the level of cli from aggressor ues. the resources used for the cli measurement may be resources not scheduled by the base station for use by the victim ue for downlink reception, but are scheduled for use by the aggressor ues for transmitting uplink traffic or for transmitting reference signals used to characterize the uplink channel. the victim ue may report the cli measurements to the base station for the base station to adjust scheduling of downlink resources to the victim ue. in one aspect, the signaling from the base station may indicate to the victim ue the locations of scheduled downlink symbols that may potentially be impacted by cli.
