协同通信是目前无线通信的研究热点之一,协同通信中的节点选择,功率分配等问题已得到深入的研究,但对于多业务传输问题目前并没有得到足够的关注。通过建立协同通信中的资源分配模型,基于效用的自适应协同多业务传输(utility-based adaptive cooperative multi-traffic transmission,UACMT)算法解决了多业务在协同通信中的传输问题,并能够自适应的在协同与非协同传输模式中进行选择。系统级仿真结果表明与传统协同和非协同传输相比,UACMT能够在一定误块率BLER约束条件下提高用户的业务效用。
Collaborative communication is one of the research hotspots in wireless communication. The problems of node selection and power allocation in cooperative communication have been studied deeply. However, there is not enough attention on the problem of multi-service transmission. By establishing a resource allocation model in collaborative communication, the utility-based adaptive cooperative multi-traffic transmission (UACMT) algorithm solves the problem of multi-service transmission in cooperative communication and adapts Choose between coordinated and non-cooperative transmission modes. The system-level simulation results show that compared with traditional cooperative and non-cooperative transmission, UACMT can improve user’s business utility under a block error rate BLER constraint.
