TD-LTE FDE Band Collaborative Research Network Analysis

December4,2013the MIIT released TD-LTE4G licenses to three operators ofChina, marking the operators can go fully prepared to carry out a large-scale networkconstruction from the pilot. In the construction process, limited spectrum resources andrequire operators of the need for efficient use of valuable spectrum to cope withintensive coverage cities, business districts, suburban and rural areas, such as complexscenes, therefore, how to build an effective and efficient use of resources scale4Gbecome a major network operators are currently the most urgent needs, collaborativenetworking F/D/E band for China mobile is therefore of utmost importance.TD-LTE wireless network with respect to the TD-SCDMA RNC canceled NE, NEsimplified structure, the network architecture more flat and simplistic, reduce systemcomplexity and transmission and wireless access delay, reduce network deployment andmaintenance costs, improve network efficiency and performance. Meanwhile,collaborative and effective use of hybrid network of TDD spectrum resources becomesthe key TD-LTE network and efficient networking.This paper describes a hybrid collaborative network of TD-LTE F/D/E bandwireless networks, as well as the analysis of TD-LTE spectrum resources, introduceTD-LTE radio network architecture that introduces TD-LTE wireless gateway keytechnologies, including OFDM, MIMO, ICIC and HARQ, etc.; Meanwhile, Chinamobile mastered F/D/E band performed three TD-LTE network simulation analysiscollaborative research and test validation.
