Capacity Projectors for Dynamic MU-MIMO Channel Shaping

The patent combines multiple small cell base stations into a coordinated multi-point (CoMP) system where they function as a unified network entity. This merging approach allows joint processing of signals across multiple cells, achieving high data rates without requiring separate complex backhaul connections for each individual small cell, thus resolving the contradiction between capacity improvement and network complexity.

The patent implements a universal backhaul architecture where a single high-capacity backhaul connection serves multiple small cells through centralized processing. This multi-functional backhaul infrastructure replaces the need for dedicated backhaul links for each small cell, reducing overall network complexity while maintaining high data rate capacity across the dense small cell deployment.

The patent implements self-organizing network (SON) capabilities that enable base stations to automatically perform RF measurements, detect interference patterns, and coordinate with neighboring cells without human intervention. This self-service approach reduces inter-cell interference through automated coordination while eliminating the need for manual RF planning, thus resolving the contradiction between interference reduction and deployment complexity.

The patent establishes feedback mechanisms where base stations continuously monitor RF conditions, measure interference levels, and adjust their transmission parameters based on real-time feedback from the network environment. This closed-loop feedback system enables dynamic interference coordination that reduces inter-cell interference without requiring complex pre-planning, as the system adapts automatically to changing conditions.

The patent segments the coverage area into multiple zones served by different base stations in the CoMP system. Distant UEs at cell edges are served by coordinating multiple base stations that collectively provide coverage, rather than relying on a single base station's beamforming. This segmentation approach maintains SINR for distant UEs by distributing the service burden across multiple nodes, resolving the contradiction between extended coverage and maintained signal quality.

The patent introduces coordinated multi-point processing as an intermediary mechanism that relays signals between distant UEs and the core network through multiple base stations. This intermediary approach allows signals from distant UEs to be collected and processed jointly by multiple base stations, compensating for large-scale fading and maintaining acceptable SINR levels at cell edges while extending coverage area.
