Adaptive forward link formation for terminal collaborative reception

Abstract

Collaborative reception has been proposed to improve the frequency utilization efficiency in wireless networks. This paper proposes adaptive forward link formation that selects not only terminals to forward received signals to the destination but also higher frequency bands for the forward link. More-over, this paper proposes a complexity-reduced algorithm for the selection. The proposed formation achieves about 2-times higher frequency utilization efficiency than the fixed formation. While the proposed complexity-reduced algorithm attains similar frequency utilization efficiency as the exhaustive search, the proposed algorithm reduces the complexity of the selection to almost 1/200 of the exhaustive search.
