A Weight Based Channel Scheduling for LTE-A Femtocells

In LTE-A, uplink channel allocation is mandated by the contiguity paradigm, which requires computational complexity and intricacy. With the massive deployment of small cells, e.g. femtocells, user experience in the uplink is as vital as in the downlink. PAPR is the critical factor in the SCFDMA network that allows low power consumption and contiguous resource allocation. In SC-FDMA, a contiguous resource block is required to take advantage of the PARP. An uplink channel scheduling algorithm for uplink operation can reduce the PAPR in transmission. An efficient and optimised uplink channel scheduling algorithm will allow the system to maximise resource occupation and uplink channel allocation. A weight-based resource allocation algorithm is proposed to improve the network performance in the LTE-A uplink femtocell network. Simulation results show that the proposed algorithm performs better for uplink and eliminates the gap of the current channel scheduling algorithms for the LTE-A femtocell.
