Popis:	This paper presents an improved resource scheduling scheme by integrating cognitive radio into LTE-A self-organizing networks (SON). To avoid mass signaling overheads produced by traditional channel quality indicator (CQI) report mechanism in frequency scheduling, we particular adopt power sensing provided by low power nodes (LPNs) to compute the quality of each resource block (RB), then take advantage of the classical schedulers and construct a distributed adaptive resource allocation model for LPN in HetNets. Our work not only facilitates the frequency domain packet scheduling (FDPS) implementation with less computation complexity compared with traditional scheme. Simulation results also show that our proposed scheme can achieve considerable system performance improvement.
