Energy consumption in wireless communication system is rapidly increasing due to the growth in wireless multimedia access. Combating the adverse effects of excessive energy consumption demands for energy-aware system design called green communication, which has become the major focus of many researchers recently. In this paper, we propose user selection and power allocation schemes for a multi-user...
In this paper a novel framework for extending QoS to QoE in wireless networks is introduced. Instead of viewing QoE as an off-line apriori mapping between users' subjective perspective of their service quality and specific networking metrics, we treat QoE provisioning as a dynamic process that enables users to express their preference with respect to the instantaneous experience of their service performance,...
The resource allocation and limited feedback scheme are proposed in multiuser MIMO OFDM systems. The optimization model is to maximize the throughput with minimal and maximal transmit rate constraint of users, which can effectively guarantees the QoS requirement of multimedia traffics. The resource allocation is divided into user selection and power allocation, realizing the optimization separately...
