Abstract
Throughput is a key indicator for competitive priority of 4G network.There are many factors that affect throughput.In addition to network quality
the throughput difference mainly depends on network scheduling algorithm which is jointly implemented by UEs and eNode B.UEs report CQI and RI after signal monitoring
then eNode B output TM
MCS and RB information which are according to scheduling algorithm.Based on large amount of testing
this paper presents three major superior principles that TDLTE network throughput should follow
and provides theoretical basis for subsequent TD-LTE network planning and optimization.
