A green resource allocation strategy for utilizing cooperative spatial multiplexing

Building green communication systems is a part of building the harmonious society. A novel resource allocation algorithm was proposed to reduce the energy consumption of future communication systems by utilizing cooperative spatial multiplexing. In this algorithm, the number of cooperative nodes was determined by source power control and level of cooperation (LOC) adjustment to minimize the energy consumption of the system under the QoS constrains. Simulation results show that the performance of the scheme is superior to those of existing algorithms.
