CoMP Signaling Compression for Backhaul Delay

The patent applies preliminary action by having eNBs predict future channel states and pre-compute precoding matrices before actual transmission occurs. The prediction-based approach allows the system to prepare coordination decisions in advance, compensating for backhaul delays by ensuring the planned actions remain valid when executed.

The patent implements dynamics by transitioning from static, delay-prone centralized coordination to dynamic distributed coordination. Each eNB independently updates its precoding decisions based on real-time channel predictions and local feedback, allowing the system to adapt quickly to changing conditions without being constrained by backhaul latency.

The patent extracts only the essential coordination information needed for interference management and transmits it via X2 interface, rather than exchanging complete precoder feedback. Specifically, eNBs share predicted channel state information and coordination decisions relevant to inter-cell interference, filtering out redundant details to reduce backhaul load while maintaining coordination effectiveness.

The patent applies self-service by enabling each eNB to independently process and interpret the received coordination information locally. Instead of requiring centralized processing of all feedback data, each eNB uses the shared information to make autonomous precoding decisions, reducing the need for extensive information exchange and backhaul capacity.
