This paper studies the problem of joint allocation of transmission power and bandwidth in cooperative networks. The goal is to minimize transmission energy consumption in a network with M coordinated transmission points (CTPs) under respective data rate constraints of N mobile terminals (MTs). We propose a joint power and bandwidth allocation scheme for downlink data transmission based on mathematical...
We consider in this paper an uplink coordinated beamforming problem for multi-cell heterogeneous networks (HetNets) whereby base stations are densely and co-channel deployed. A joint user-base station association, power control and beamforming scheme is presented for HetNets to minimize the power consumption. Such joint optimization is formulated as a mixed-integer second-order conic programming (MI-SOCP)...
