Design and Implementation of Carrier Aggregation in LTE—An Air-Interface Analyzer

Abstract

Focusing on difficulties in communication networks test and optimization since some key technologies like carrier aggregation applied in communication networks, a LTE-An air-interface analyzer design scheme was proposed, which supports 3GPP R10/11 protocol standards and carrier aggregation. Firstly, the physical and logical architecture of LTE-A air-interface analyzer was introduced, and the relationship between them, the function of each module in them was illustrated. The application of the scheme can accelerate the commercialization of carrier aggregation in communication network, speed up the network deployment process and shorten the network construction cycle, and it will play an indispensable role in communication network operation and maintenance.
