METHOD AND APPARATUS FOR RESOURCE ALLOCATION TO MAXIMIZE THE TOTAL DATA RATE IN SC-FDMA UPLINK

摘要

A low-complexity Radio Resource Allocation method (100,200) efficiently assigns frequency resources, such as a set of contiguous subcarriers, to Mobile Terminals in SC-FDMA uplink systems. The inventive method initially finds the resource allocation that leads to maximum efficiency in terms of transmitted data rate, without considering any resource adjacency constraint. Subsequently, the method iteratively redefines the resource allocation in order to find a resource allocation that is in accordance with resource allocation adjacency required by the SC-FDMA multiple access scheme.
