Dynamic Inter-Cell Interference Coordination to Optimize XR and eMBB Coexistence

This paper presents a dynamic inter-cell interference coordination (ICIC) technique that enhances extended reality (XR) capacity, while minimizing the impact on enhanced mobile broadband (eMBB) traffic in a multi-cell multi-user network. The network identifies victim XR users based on their experienced performance and dynamically coordinates with aggressor cells for muting in specific transmission time intervals to alleviate interference for the victim users. Extensive dynamic system-level simulations demonstrate the effectiveness of the proposed ICIC scheme, achieving a 22-32% gain in XR capacity while incurring a degradation of 12-22% in average eMBB cell throughput.
