| Abstract: | Femtocells are a promising solution to enhance indoor coverage and system capacity.Hybrid access methods reach a compromise between the performance of subscribers and non-subscribers.In this paper,a Weighted Proportional Fair(WPF) algorithm is proposed,in which different users with different weights,for the downlink hybrid access OFDMA femtocell networks.Besides,two algorithms are developed to obtain the user scheduling weight.The one is that adaptively change the scheduling weight,the other is based on the... |
