An Autonomous Resource Block Assignment Scheme for OFDMA-Based Relay-Assisted Cellular Networks

Terminal relaying offers an effective means for improving the performance of OFDMA-based wireless networks. However, with the increase in the number of Relaying Terminals (RTs), their coordination becomes a cumbersome task. To address this drawback, in this paper an autonomous scheme is proposed whereby the RTs assign Resource Blocks (RBs) to incoming Wireless Terminals (WTs) in a way that minimizes the number of hit occurrences at which the same RB is assigned to multiple-WTs. The proposed scheme uses cyclic group generators to determine the sequence of RBs to be assigned by each RT.
