An out-of-synchronization condition for a Universal Mobile Telecommunications System (UMTS) is defined for a situation in which it may be difficult to distinguish an out-of-synchronization condition in a downlink dedicated channel from interference on that channel. A request is sent on an uplink from a user equipment (UE) to a base station transceiver (BST) for increased power on a downlink channel experiencing a possible frames out-of-synchronization condition, which may instead be a possible interference condition, so as to attempt to eliminate the possible interference. After a first selected period of time without eliminating the possible interference problem, the uplink is terminated unless a broadcast downlink channel is determined to be experiencing interference below a selected level, in which case the UE is allowed to continue to send the request for increased power. Only after a second selected period of time without eliminating the possible interference problem is the uplink terminated. |
