When a handover request for performing a handover of a terminal () from a macro cell Cto a CSG cell Cis received from an SeNB(S), a base station (TeNB) () of the CSG cell Ctransmits a handover response in accordance with a handover enabled/disabled state (S). The handover response includes an identifier of the terminal () in the CSG cell C. Upon receiving the response, the SeNB () notifies the identifier to the terminal () (S). The TeNB () repeatedly transmits a dedicated signal containing a handover command via a dedicated channel set using the identifier at an interval shorter than a gap period (S). Accordingly, whether or not access is permitted can be judged promptly and a smooth handover can be realized.

Radio communication apparatus and method of handover from a macro cell to a closed subscribers group cell

When a handover request for performing a handover of a terminal () from a macro cell C1 to a CSG cell C2 is received from an SeNB(S), a base station (TeNB) () of the CSG cell C2 transmits a handover response in accordance with a handover enabled/disabled state (S). The handover response includes an identifier of the terminal () in the CSG cell C2. Upon receiving the response, the SeNB () notifies the identifier to the terminal () (S). The TeNB () repeatedly transmits a dedicated signal containing a handover command via a dedicated channel set using the identifier at an interval shorter than a gap period (S).

Radio communication terminal and method of handover from a macro cell to a closed subscribers group cell

Base station, radio communication system, and handover method

A wireless communication terminal apparatus and wireless communication method, wherein the time necessary for implementation of handover is reduced without increasing the complexity of the configuration of the wireless communication terminal apparatus. A gap confirmation unit () determines to start the UE-initiated GP at the current DRX cycle in cases when the extended DRX active period is shorter than the UE-initiated GP start offset, and determines to start the UE-initiated GP at the next DRX cycle in cases when the extended DRX active period is longer than the UE-initiated GP start offset. A UE-initiated GP configuration unit () generates a gap pattern at the determined DRX cycle.

Wireless communication apparatus and wireless communication method using a gap pattern

Disclosed is a gap support measuring method which performs autonomous gap allocation without lowering the data transfer rate or the throughput. STacquires various kinds of parameters decided by a network so as to execute a gap support measurement task. STchecks the current time and starts the gap support measurement task when the current time has become Ts. STjudges whether CQI measured by a terminal is lower than a threshold value. STjudges whether the threshold value should be updated. STdecides the gap length according to the remaining gap length and the remaining time and performs measurement within the gap. STjudges whether the measurement is complete. STchecks whether the total of the gaps exceed the entire gap length Tg.
