摘要
在协作多点传输(coordinated multiple points transmission,CoMP)的联合传输(joint transmission,JT)系统中,为了提高用户的服务质量,提出了一种基于用户满意度的多小区资源分配算法。该算法基于用户累积时延构建了一个用户满意度函数,将客观时延和吞吐量转化为主观满意度,再通过最大化所有用户的满意度,推导出了一个有效的单小区资源初始分配算法,最后在多小区资源分配过程中通过集中控制单元对所有小区资源进行最终分配。理论分析与仿真结果表明,与传统算法相比,该算法能够在公平性,时延和吞吐量方面能够更好地适应用户的需求。
In this paper, we propose a suitable multi-cell resource allocation algorithm to improve users' quality of service in CoMP-JT system. In the algorithm, a user satisfaction function is firstly built by using user' s accumulated delay, which convert objective time delay and throughput to user satisfaction, then we derive an effective single cell initial resource allo- cation algorithm through maximizing the satisfaction of all users, finally all cells' resources are unified allocation by the central control unit. Simulation results show that compared with traditional algorithms, this algorithm can better adapt the user~ needs in fairness, latency and throughput.
