Abstract
Disclosed are systems, methods and structures that provide improved spatial reuse of spectral resources in small-cell wireless networks including WiMAX, LTE, LTE-Advanced, etc. Advantageously, the systems and method disclosed while leveraging beamforming for spatial reuse across small cells also decouple it from per-frame scheduling at a small cell base station thereby allowing for beam selections to be computed with a granularity measured in seconds. In realizing these advantages, systems, methods and structures disclosed integrate beam selection with client association.
