Abstract
A measuring method for observation time difference of same frequency and multiple cells is characterized in that observation time difference of every adjacent cell is acquired by calculating channel impact response of every cell, channel impact response peak position of every cell and OTD average value of every adjacent cell by utilizing received DwPTS information from local cell, SYNC-DL code configuration information of adjacent cell acquired by broadcasting information of local cell, single cell channel estimation, effective path judgement threshold calculation, SUC ranking, SUC calculation, especially when UE is positioned at border of multi-adjacent cells, UE accurately measures the observation time difference for multi-cells of same frequency. The invention solves problem that traditional measurement has bad result which can not satisfy demand of performance, and provides technical support for widely generalization of third generation TD-SCDMA communication system.
