摘要： It is possible to provide a radio transmission device, a radio reception device, and a radio communication system which can effectively use a resource of a unicast/MBMS cell and prevent increase of a signaling amount accompanying a cell switching. A UE measures a reception level of an MEMS-dedicated cell. When the measured reception level is below a first threshold value, the UE switches the serving MBMS cell from the MBMS-dedicated cell to the unicast/MBMS cell. Moreover, when the reception level of the MBMS-dedicated cell exceeds a second threshold value obtained by adding an offset value to the first threshold value, the serving MBMS cell is switched from the unicast/MBMS cell to the MBMS-dedicated cell.

摘要： Disclosed is a gap support measuring method which performs autonomous gap allocation without lowering the data transfer rate or the throughput. ST301 acquires various kinds of parameters decided by a network so as to execute a gap support measurement task. ST302 checks the current time and starts the gap support measurement task when the current time has become Ts. ST303 judges whether CQI measured by a terminal is lower than a threshold value. ST304 judges whether the threshold value should be updated. ST306 decides the gap length according to the remaining gap length and the remaining time and performs measurement within the gap. ST307 judges whether the measurement is complete. ST308 checks whether the total of the gaps exceed the entire gap length Tg.

摘要： A wireless communication terminal apparatus and a wireless communication method wherein a measurement operation, which is suitable for a long DRX/DTX interval, is controlled without providing any new signaling between a terminal and a base station. When a DRX threshold terminal status determining part (107) determines that a set a DRX/DTX interval is longer than a DRX threshold, a measurement process deciding part (108) instructs a measurement implementing part (109) to use information for cell reselection. The measurement implementing part (109) then uses the information for cell reselection to perform a measurement. When a result of the measurement satisfies a cell reselection requirement, a measurement report transmission process deciding part (110) decides a transmission of a measurement report, which is then transmitted from a transmitting part (111) to a wireless communication base station apparatus currently connected.

摘要： The invention relates to methods for establishing a radio bearer between a network element terminating radio resource control protocol and a mobile terminal. The invention provides RNC for establishing a radio bearer between the RNC and a mobile terminal, especially adapted mobile terminals and a system comprising the network element and at least one mobile terminal. In order to reduce the delays implied by the signaling in the procedure the invention proposes two mechanisms. The first mechanism aims at reducing the delay implied by setting up the radio link for the radio bearer by preconfiguring a pool of resources comprising a set of at least radio bearer configuration and making the available radio bearer configurations known to the mobile terminals. The second mechanism aims at avoiding the delay implied by the explicit assignment of a radio network temporary identifier by signaling a set of available identifiers from which the mobile terminal may choose an identifier.

The invention is also providing apparatus and system for performing these methods, and computer readable media the instructions of which cause the apparatus and system to perform the methods described herein. In order to allow for aligning the timing of uplink transmissions on uplink component carriers, where different propagation delays are imposed on the transmissions on the uplink component carriers, the inventions suggests to time align the uplink component carriers based on a reference time alignment of a reference cell and a reception time difference or propagation delay difference between the downlink transmissions in the reference cell and the other radio cells, the uplink component carriers of which need to be time aligned.
