dc.description.abstract | Small cells form a critical component of next generation cellular networks, where spatial reuse is the key to higher spectral effi- ciencies. Interference management in the spatial domain through beamforming allows for increased reuse without having to sacrifice resources in the time or frequency domain. Existing beamforming techniques for spatial reuse, being coupled with client scheduling, face a key limitation in practical realization, especially with OF- DMA small cells. In this context, we argue that for a practical spatial reuse system with beamforming, it is important to decouple beamforming from client scheduling. Further, we show that jointly addressing client association with beamforming is critical to maxi- mizing the reuse potential of beamforming. Towards our goal, we propose ProBeam – a practical multi-cell beamforming system for reuse in small cell networks. ProBeam in- corporates two key components - a low complexity, highly accurate SINR estimation module that helps determine interference depen- dencies for beamforming between small cells; and an efficient, low complexity joint client association and beam selection algorithm for the small cells that accounts for scheduling at the small cells without being coupled with it. We have prototyped ProBeam on a WiMAX-based network of four small cells. Our evaluations reveal the accuracy of our SINR estimation module to be within 1 dB, and the reuse gains from joint client association and beamforming to be as high as 115% over baseline approaches. | - |
