无线通信网络中面向多源异构业务的时延服务质量保障机制研究

Since the services may vary dramatically in both the large range from millisecond to a few seconds and the diversity from uniform/constant delay-bound to different/variable delay-bound guarantees among different wireless links, the delay-bound quality of service (QoS) requirements for different types of services promotes the new heterogeneous statistical delay-bound QoS provisioning, which is one of most critical problems in the fifth (5G) wireless networks. ..Existing schemes for QoS guarantees ignore the heterogeneity of wireless traffics, thus failing to maximize the effective capacity for heterogeneous traffics based wireless networks. To resolve the aforementioned problem, this project places the research emphasis on the mechanism of how to guarantee delay-bounded QoS for heterogeneous traffics based wireless networks. First, we build the aggregate effective spectrum efficiency/aggregate effective power efficiency model and formulate the corresponding maximization problems. Second, we develop the heterogeneous-QoS-driven resource allocation schemes to maximize the effective spectrum efficiency and the aggregate effective power efficiency, respectively. Third, we design the joint effective spectrum efficiency and aggregate effective power efficiency optimization criterion and develop the corresponding optimization scheme. The research results are expected to not only guarantee delay-bounded QoS for heterogeneous traffics, but also provide a new way for efficient wireless networks with high spectrum efficiency and low power consumption.

第五代无线通信（5G）网络中应用场景的多样化直接导致网络业务呈现多源异构性，这表现在无线通信网络的某个局部呈现出各种业务以及多种技术混合的状态，这为保障5G网络的服务质量提出了新的挑战，其中时延服务质量保障是关键点。..传统的时延服务质量保障策略没有考虑业务的多源异构性，使得这些策略在新型的通信技术条件下并不能达到网络最优的有效容量。针对该问题，本课题拟开展无线通信网络中面向多源异构业务的时延服务质量保障机制研究。首先，构建多源异构集合有效频谱效率/集合有效功率效率模型及相应的最大化问题；在此基础上，提出面向多源异构业务的集合有效频谱效率/集合有效功率效率的优化方法；给出集合有效频谱效率与集合有效功率效率联合优化准则与优化方法。本课题的研究成果不仅给多源异构业务提供了时延服务质量保障的有效方法，也为追求高谱效、低功耗的5G及未来无线通信网络提供了新途径。
