The current power consumption of intelligent terminals are over burden for their battery capacities, which directly restrict the hours used. In order to realize the energy saving of terminals in the LTE-A system, this paper puts forward the concept of virtual cells and a related uplink energy saving mechanism. Virtual Cell's resources and the outage probability of terminals are proposed by this mechanism...
This letter introduces a centralized joint power and admission control algorithm for cognitive radio networks. Its novelty lies in the proposed admission metric. Unlike those in existing algorithms, our metric predetermines the admission order of N secondary users which intend to access the network. This allows us to search a group of admitted secondary users with the bisection method. The proposed...
Emerging high-density WLANs in urban areas and enterprises offer great potential to accommodate the anticipated explosion of demand for wireless data services. To make it successful, it is critical that the network utilizes the limited radio resources efficiently while satisfying predefined quality of service (QoS) requirements. In this paper, we develop a real time and open ended algorithm for joint...
