The frequency division duplexing (Frequency Division Duplexing, FDD) system of the current universal mobile telecommunications system (Universal Mobile Telecommunications System, UMTS) supports 5M bandwidth and multi-carrier technology. However, in the multi-carrier configuration, the pairing relationship between uplink and downlink carriers must be satisfied, that is, one uplink carrier must uniquely correspond to one downlink carrier. The uplink access of the user equipment (including acquisition of synchronization, system broadcast, control channel, etc.) depends on the corresponding downlink carrier.
