Adaptive cross-link interference measurement and reporting framework
In a wireless network, a base station may configure a victim user equipment (UE) experiencing interference with a periodic measurement resource using Layer 3 (L3) signaling, and the UE may report cross-link interference (CLI) measurements to the base station using L3 messages. However, using L3 signaling to configure interference measurement and reporting may result in an inflexible interference measurement configuration and a long latency to report CLI and/or self-interference feedback. Furthermore, although Layer 1 and/or Layer 2 (L1/L2) CLI reporting may be more suitable to track and adapt to dynamic changes in interference conditions, L1/L2 signaling increases control signaling and CLI management overhead at the base station. Accordingly, some aspects described herein relate to an adaptive L3 CLI measurement and reporting framework, where L3 messages may include one or more adaptive fields to support flexibility in configuring CLI measurement and/or CLI reporting parameters.
