The weight computing of covering size: the statistics based on TA in terminal access procedure is calculated based on TA, indirectly judgement covering
The variation of size.TA as shown in table 2 below for RRU1 sector count half an hour is distributed, and adjusting the angle preceding base station covering radius is
Within 350m, therefore it can be analyzed with the ratio that TA is 4 or more when being counted.Weight is 10/1614 before adjusting the angle,
It is 583/1215. after adjustment angle
