RF energy harvesting based on wireless energy transfer (WET) can release mobile terminals from battery constraint and has drawn significant research interest. In this paper, in order to solve the problem of Simultaneous Wireless Two-Way Information and One-Way Energy Transfer (TWI&OWE-SWT) in MIMO systems, an Adaptive Time-slot and Power Allocation Scheme (A-TPAS) is proposed. And to maximize...
Despite the advantages of deploying femtocells into cellular networks, the consequent cross-tier interference has seriously limited the network performance. Applying different power control techniques has been heavily discussed in 3GPP as an efficient approach for handling dominant interference scenarios. Instead of relying on system level simulations, this paper evaluates an analytical uplink power...
In order to reduce the impact of adjacent channel interference (ACI) to other licensed system deploying at the adjacent channel, nearly 10% of the system bandwidth at the edge of the transmitted bandwidth is reserved as guard band. Generally, transmitting on guard band increases data rate for one system but the followed ACI decreases another system deploying adjacently in frequency, which might decrease...
In this paper, web response time is utilized to indicate the performance of web cache in asymmetrical wireless network. The impacts of WAN delay, user load level and link asymmetries on web response time are investigated in our evaluation. Our study demonstrated that caching scheme performs poorly when uplink quality degraded. Based on the analysis of correlations between cache performance and link...
In this paper, we described the correlations between uplink packet latency of TCP, application traffic characteristics and uplink characteristics. Our study demonstrated that the packet latency in uplink direction mainly caused by TCP setup time instead of the packet size and the bandwidth. In addition, we also found that TCP failure number varies with the configurations of PDCH in BSS.
