Multi-user mimo via frequency re-use in smart antennas

摘要: Embodiments of a mobile communications system to service multiple users over same spectrum in coordinated multi-user communication network and method are generally described herein. The serving signals for transmission user equipment (UE) spoke-and-hub configurations will utilize composited transfer functions (CTF) selected characterized based on channel state information (CSI), which comprises responses from probing signal sequences multipath dominated propagation channels accordance with dynamic distribution. A is point-to-multipoint function constructed by combining point-to-point functions. shaping via beam forming optimizations transmitters be “user dependent” enhanced suppressed other users. (CTFs) constrained desired performance criteria, not as directions angles, but indexed elements identifications UE. These referred constraints. When operating coordination modes, more UEs operational concurrently interferences intended UE using the frequency resources. criteria may include those many beam-shaping techniques, such orthogonal beams (OB), quiet-zones, others.
