- 摘要:
- 为了提高无线通信系统的传输效率,通过设置不同阈值提出了一种具有用户优先级的载波聚合无线资源分配方案.该方案首先针对用户的不同类型(宽带用户和窄带用户、始发用户和切换用户)将其设置为不同的优先级;然后通过设置两个阈值将无线资源块分配给不同的优先级用户,以此在能够保障宽带用户获得最低服务质量的前提下,提高高优先级用户的切换成功率和系统的吞吐量.性能验证结果表明,该方案在提高系统的总吞吐量和切换成功率方面显著优于无用户优先级的载波聚合资源分配方案,因此该方案在使用载波聚合技术的无线网络中具有良好的应用价值.
- Abstract:
- To improve the transmission efficiency of wireless communication system, a carrier aggregation radio resource allocation scheme with user priority was proposed by setting different thresholds.The scheme first set different priority for different types of users (wideband users and narrowband users, originating users and handoff users); then, two thresholds were set to control the number of wireless resource blocks allocated to different priority users, so as to improve the handoff success probability of high-priority users and improve the system throughput under the premise of ensuring the minimum quality of service for broadband users.The performance verification results show that this scheme is significantly superior to the carrier aggregation resource allocation scheme without user priority in improving the handoff success probability and the total throughput of the system.Therefore, this scheme has a good application value in wireless networks using carrier aggregation technology.
