In this paper, power allocation for device-to-device (D2D) communication underlaying cellular networks is investigated. Our optimization task is to maximize the sum rate of the cellular link and the D2D link subject to the maximum power budget and intercell interference constraints. An efficient iterative algorithm is proposed to address the formulated intractable problem, to which the global optimum...
The increasing demand on higher transmission speed and lower latency has become popular in 5G related researches. Cooperation is one possible solution to enhance system performance. In this work, we focus on the problem of enhancing the performance of cooperative among mobile terminals under the constraint of cooperative link capacity. Different from traditional researches, we consider the scenario...
With the increasing demand of transmission speed and more robust quality of service, the capacity constrained backhaul gradually becomes bottleneck in cooperative wireless networks, e.g. in Joint Processing mode of LTE-Advanced Pro. This paper focuses the fact of resource allocation with limited backhaul capacity in uplink cooperative networks, where two base stations (BS) equipped with single-antenna...
Resource allocation problem in high-speed railway wireless communication networks is one of the key issues to improve the efficiency of resource utilization. However, traditional resource allocation methods cannot be directly applied to this special communication system. In this paper, we propose a resource allocation approach for high-speed railway downlink orthogonal frequency-division multiplexing...
Resource allocation problem in cognitive radio networks (CRN) is one of the key issues to improve the efficiency of spectrum utilization. Most of previous work on resource allocation mainly concentrates on the secondary users (SUs) with only one type of service requirement, without considering the scenario with heterogenous services requirement. In this paper, we study the dynamic channel and power...
In cognitive radio networks (CRN), underlay spectrum sharing allows secondary users (SUs) to utilize the spectrum on which the primary users (PUs) in primary radio networks (PRN) are working at the same time, without introducing intolerant interferences. In this paper, we study the joint transmission power and time allocation in CRN with underlay spectrum sharing technology. To maximize the total...
