摘要: In this paper, a joint resource reallocation algorithm based on cognitive radio (CR) is investigated for power-constrained user equipment, in multi-homing heterogeneous system with limited original subcarriers. Currently, all relevant works consider systems where networks run separate frequency bands. Unlike them, we assume that they are capable of sharing spectrum resources by adopting CR to improve the utilization efficiency. conventional allocation, jointly reallocate both and detected new running sensing results. This paper first proposes CR-based uplink method condition can share resources. Then formulate proposed method, adopt continuity relaxation convert formulated problem into convex optimization problem, solve it. Finally, simulation results demonstrate significantly improved performance our i.e., throughput energy efficiency over benchmark.
