This paper addresses the problem that devices are reluctant to participate in local device-to-device (D2D) communications in the purpose of improving the data transmission quality. We propose a novel game-theoretic approach of joint source selection and power control, which enhances the multimedia transmission quality with latency constraint. The proposed approach first analyzes the interactions between...
In this paper, the mode selection (underlay or overlay) for device-to-device (D2D) links at low layers is jointly analyzed with the video coding mode selection and multiple transmission path selection at high layers. For each packet, three video coding modes (I, P, and B) and three transmission paths (cellular link with/without the shared relay and D2D link) are considered to optimize the received...
3D beamforming is an important technic to enhance system capacity, in future communication system. However, with the rapid development of high speed data services, unexpected growth of traffic could develop in beams and create regional traffic congestion. Conventional hot-spot traffic relief methods do not apply to 3D beamforming network, it is necessary to study the hot-spot traffic relief problem...
