<p>A recognition method of identifying primary cell in site selective diversity transmit (SSDT), comprise the steps of: (1) system allocates ID to each cell; (2) UE periodically send the primary cell ID to connected cell by upline FBI field; (3) base station receives the primary cell ID from mobile station, if the signal received by base station meets any of following conditions, then said base station regards itself as primary cell; Identification condition is: A. received primary cell ID code matchs with the ID code of itself; B. received upline signal quality is under the quality threshold Qth, meanwhile, received primary cell ID code matchs with local cell itself ID code in a certain extent; C. the use of upline reducing mode makes the losing of ID code overrun the limitation. A few non primary cells which want to transmit signal to UE were avoided, thereby system interference was reduced, and system stability and system capacity were improved.</p> |
