Co-operative relaying is accepted as a promising solution to achieve high data rates over large areas in the future 4G wireless system. In this paper, an Adaptive Cooperative Relay Selection Algorithm (ACRSA) is presented for fixed relay based cellular networks. According to current user density in a certain cell, when two-hop transmission is adopted, ACRSA adapts selectively between two different cooperation schemes. These are realized either between the parallel transmission between the base station and a relay node, or by adopting parallel transmission between another mobile terminal and a relay node.
