Currently

due to the characteristics of the TD-LTE network technology

as well as the positioning of its market operations

TD-LTE network depth coverage requirements are more stringent.This article describes the challenges facing TD-LTE depth coverage and analysis of the ability of the comprehensive coverage of the TD-LTE network deployments band

and proposed to solve the TD-LTE network depth coverage problem in heterogeneous network construction technique

and the technologythe program was discussed in detail.
