Performance upper bounds for coordinated beam selection in LTE-Advanced

Jochen Giese, M. Awais Amin
2010 2010 International ITG Workshop on Smart Antennas (WSA)  
Coordinated Multipoint (CoMP) transmission techniques have been considered as tools to improve cell-edge and average data throughput for LTE-Advanced.  ...  First investigations of CoMP techniques in homogeneous hexagonal macro layouts have shown that interference coordination needs to involve dominant interferers to allow significant gain.  ...  EVALUATION We performed system-level simulations to find upper bounds on observable gains for coordinated beam selection using throughput as a performance metric.  ...
