Zone-based power control scheme for multi-cell interference environments
Sung-Yun Yun, Bae Sung-Oh, Jaesung Lim · 2002
We propose a new transmission power control (TPC) scheme called zone-based power control (ZPC). The proposed ZPC scheme employs a mechanism that controls both the power and rate of high-rate data traffic according to the location distribution of mobile stations. Simulation results show that the proposed scheme yields a significant performance improvement compared with the conventional TPC scheme in terms of the power consumption, service coverage and the traffic throughput of portables.
