High speed uplink packet access ( hsupa ) is a new work item of technical specification release 6 in 3gpp . wcdma system . the techniques of this work item , i . e . node b controlled scheduling , hybrid arq with chase combining , shorter tti , are to improve the performance of uplink dedicated transport channels , i . e . to increase capacity and throughput and reduce delay 在hsupa中通過采用基站nodeb控制調度、結合了軟合并的混合自動重傳請求( harq ) 、更短的傳輸時間間隔( tti )等關鍵技術,不但增強了系統(tǒng)容量與覆蓋還使用戶設備( ue )能獲得更大的上行吞吐、更小的傳輸延時。
Much reference of the algorithms and models can be got from the performance results for the practical design and layout . system - level simulation of hsupa builds the integrated platform and key models to describe and simulate the common structure and features of the radio network , including cell layout , path gain , traffic model , power control , handover , etc . , also the special ones of hsupa , including mac - es / e , node b controlled scheduling , harq , shorter tti , etc . 所謂hsupa系統(tǒng)級仿真就是要搭建系統(tǒng)級的仿真平臺,對無線網絡的公共結構和特性(例如小區(qū)布局,傳播模型,衰落信道,天線模型,功率控制,切換, ue的分布和移動,業(yè)務的建立終止和中斷等)和hsupa的專有結構和特性( mac - es / e , nodeb控制的調度, harq ,更短的tti )進行描述和建模。
The techniques of the work item , i . e . node b controlled scheduling , hybrid arq , shorter tti , are to improve the performance of uplink dedicated transport channels , i . e . to increase capacity and throughput and reduce delay . cell - level system performance of hsupa is described through the simulation results , including cell throughput of uplink packet service , system delay , capacity , fairness of ues , radio resource occupation and system device utilization 為了提高wcdma網絡傳統(tǒng)的上行專用傳輸信道( dch )的性能,即提高覆蓋、吞吐量和減少延時, 3gpp決定開發(fā)hsupa技術,提出了增強型的上行專用傳輸信道( e - dch ) ,這是一條新增的上行專用傳輸信道,專用于hsupa 。
Firstly , this paper shows the overview of these new technologies , and how wcdma system works with them ; secondly , tells about the modeling and simulation of hsupa system , and the study of the the performance of new technology and its influence on the radio network coverage ; thirdly , studys the node b scheduling mechanism and give a new algothrim to guarantee the efficiency when using the radio uplink resources ; at last , some typical umts traffic models are studied , and an algothrim to grarantee the qos of all the traffics while there are multi - traffics in cell is given 文章首先具體介紹了這些新技術和功能的特點、原理,以及這些新技術在wcdma系統(tǒng)中的應用;然后介紹了根據(jù)標準協(xié)議對hsupa系統(tǒng)進行計算機建模和仿真,并且結合仿真結果分析了新技術的性能、對系統(tǒng)覆蓋與容量的影響;隨后對hsupa技術的nodeb調度進行了研究,并提出了保證上行資源利用效率的調度機制;最后,對一系列umts業(yè)務模型進行了分析,并提出了基于業(yè)務服務質量qos保證的小區(qū)內多用戶并存時的調度算法。
