A joint resource allocation (RA), user association (UA), and power control (PC) problem is addressed for proportional fairness (PF) maximization in a cooperative multiuser downlink small cell network with limited backhaul capacity, based on orthogonal frequency division multiplexing. Previous studies have relaxed the per-resourceblock (RB) RA and UA problem to a continuous optimisation problem based… Continue reading

Abstract   User association and resource allocation for downlink orthogonal frequency division multiplexing are jointly optimized in small cells networks with limited backhaul. In particular, per resource block resource allocation under the backhaul constraint is formulated in pursuit of maximizing proportional fairness, which leads to an integer problem requiring prohibitive computational complexity to solve. We… Continue reading
