dc.description.abstract | This thesis considers a multicell network with multigroup multicast services occupying the same radio (i.e., time-frequency) resource. To improve the quality of service (QoS) and reduce the interference among the multicast groups, coordinated beamforming and power allocation among the cells are employed. By exploiting the concept of downlink-uplink duality, an iterative approach is taken to jointly design the group maximum signal-to-interference-plus-noise-ratio (SINR) beamforming and power allocation under the per-cell power constraints. We study two QoS-oriented optimization problems. The first problem, which is referred to as P1, is to maximize the minimum balanced level among multicast groups under per-cell power constraints, where the balanced level is defined as the ratio of the received SINR to the target (i.e., required) SINR. The latter problem, referred to as P2, is to minimize the total transmit power of coordinated cells under the worst balanced level and per-cell power constraints. Simulation results demonstrate the advantage of coordinated beamforming over the conventional single frequency network (SFN) multicast. | en |
