For 20M) and Cell C (total bandwidth resource is 20M)；Wherein cell B is the cell of eMTC, and general subscriber terminal resource occupation is
60%, in addition cell B is the resource occupation 20% of BL/CE UE distribution；C cells are pure 20M LTE cells, are used there is only common
Family terminal, resource occupation 70%.When being interacted by X2 interface resource, it is BL/ that cell B is lacked in the related news reported
The resource information namely relevant base station that CE UE are distributed can only get the general subscriber terminal resource occupation in cell B
60% (12M) can not get cell B and be the resource information 20% (4M) of BL/CE UE distribution, and get in cell C
General subscriber terminal resource occupation is 70%, is caused when being switched over to the user terminal in cell A, and cell B can will be selected
As target handover cell, but actually the remaining resources of cell C (30%) are apparent extra cell B (20%), lead to mesh
It marks cell and selects mistake, and then cause the load balance process such as subsequent cell switching that the purpose of load balancing is not achieved.
