Because of the reciprocity of the symmetric uplink channel and downlink channel in TD-LTE system

the 8-element beam forming antenna is applicable to improve the throughput of edge sector users.But the 8-element antenna is often subjected to various constraints

so it brings constructional difficulties to some base station circumstances.First

this paper compares the performances and difficulties of the 2-element and 8-element antenna’s implementation;then analyzes the feasibility of the hybrid network of 2-element and 8-element antennas by system simulation.According to the analysis

this paper gives some advices for TD-LTE system deployment.
