基于动态帧结构的多跳中继链路的资源分配

Resource allocation for multihop relay links with adaptive frame structure

在基于TDMA传输方式的多跳再生中继链路中,通过引入动态的帧结构设计使该链路上的每一跳传输所占用的时间可以进行调整。提出了在这种帧结构下多跳再生中继链路的资源分配算法,目的是在保证用户QoS需求的前提下使整个链路总的发射功率达到最小。仿真结果表明,相对于采用固定帧结构的资源分配算法,该算法能够降低总发射功率,同时能够降低用户不满意的概率。

By introducing an adaptive frame structure design to the Time Division Multiple Access（TDMA）based multihop regenerative relay links the transmitting time for each hop can be adjusted.A resource allocation algorithm is proposed for the multihop regenerative relay links with this adaptive frame structure.The objective is to minimize the total transmission power under the constraint that the user＇s QoS requirement is satisfied.Simulation results show that,compared to the resource allocation algorithm with fixed frame structure,the proposed algorithm can reduce both the total transmission power and the unsatisfying probability of the user.
