摘要： Disclosed is a technique for enabling a device that needs to send high priority and high bandwidth user plane traffic to send the user plane traffic even in the case where a group bandwidth has an upper limit in group-based communication. According to the technique, when an MTC device that is to send high priority and high bandwidth user plane traffic sends a service request to a network node (P-GW 213a), the network node allows use of a minimum bandwidth bearer in the case where the upper limit of the group bandwidth is exceeded. The MTC device sends a traffic sending request to an MTC server 214a via the bearer. The MTC server stops traffic of an appropriate other MTC device, to secure a bandwidth for the MTC device having the high priority and high bandwidth user plane traffic.

摘要： Provided are a base station, a terminal, a band allocation method, and a downlink data communication method in which a mapping method for synchronization signals and report signals is implemented with high resource usage efficiency when a first system in which an independent single communication is allocated to a unit band co-exists with a second system in which a plurality of unit bands can be allocated to a single communication. In a base station (200), an OFDM signal generation unit (225) maps primary synchronization channel (P-SCH), secondary synchronization channel (S-SCH), primary broadcast channel (P-BCH), and dynamic broadcast channel (D-BCH), which can be decoded by both an LTE terminal and an LTE+ terminal, to some of a plurality of unit bands available to the station itself. The OFDM signal generation unit (225) also maps D-BCH+, which can be decoded only by an LTE+ terminal, to all of the plurality of unit bands to produce a multiplexed transmission signal. When the terminal which has transmitted terminal capability information is an LTE+ terminal, a control unit (265) transmits a band movement indication which indicates changes in the reception band to that terminal.

摘要： When detecting occurrence of an event for transmitting a measurement report of a radio condition of a cell at a frequency set for a base station apparatus, to the base station apparatus (3) communicating with a terminal apparatus (2), the terminal apparatus (2) in a wireless communication system (1) creates a measurement report including information indicating radio conditions of cells at a frequency at which the event occurred and at another different frequency. The base station apparatus (3) controls whether or not to perform handover of the terminal apparatus (2) to another cell, on the basis of the measurement report transmitted from the terminal apparatus (2). Thereby, there is provided a wireless communication system in which a base station apparatus and the terminal apparatus are communicable with each other using multiple frequencies, the wireless communication system being capable of shortening time required for handover.

摘要： A terminal apparatus (1) which is a radio transmitting/receiving apparatus receives, from a femto cell base station (home eNB), a pilot channel signal for reception quality measurement and a synchronization channel signal for synchronization. The terminal apparatus (1) has a whitelist stored therein indicative of an accessible femto cell, and determines whether or not a CSG cell of handover destination is accessible based on a PCI of the CSG cell acquired from the synchronization channel and the whitelist. The terminal apparatus (1) then adds the PCI and a CGI to a measurement report for reception quality, and transmits the measurement report to a macro eNB (base station apparatus (2)). In this way, it is possible to suppress wasteful signaling and prevent unnecessary resources from being reserved even when two or more CSG cells that use the same PCI are present in the macro cell.

摘要： The invention relates methods for time aligning uplink transmissions by a mobile terminal in a mobile communication system, and to methods for performing a handover of a mobile terminal to a target aggregation access point. 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.

摘要： In a user equipment (UE)(100), a handover from a macro cell base station (eNB)(200) to a CSG cell base station (HeNB)(300) is controlled based on a result of comparison between reception quality from the eNB (200) and reception quality from the HeNB (300) located in a macro cell. The UE (100) comprises: a reception quality measurement unit (104) for measuring the reception quality of the eNB (200) and the reception quality of the HeNB (300); an offsetting unit (106) for offsetting the reception quality of the HeNB (300) with an offset value that makes the reception quality of the HeNB (300) relatively higher than the reception quality of the eNB (200); and an offset value correcting unit (105) for correcting the offset value according to the reception quality of the eNB (200). A user equipment is thereby provided in which handover control can be performed with an appropriate offset value that takes into consideration interference in the uplink from the user equipment to the base station.

摘要： The invention relates to a method for paging a group of MTC devices, and for transmitting parameter information to the MTC devices using the paging mechanism. MTC devices are grouped together and a different group ID per group to which the MTC device belongs is assigned to the MTC device. A specific group paging resource indication is determined for each group wherein each MTC device is assigned one of the group paging resource indications. The network pages MTC devices of a group by transmitting a paging message at the corresponding channel resources and including the corresponding group ID. Additionally, the group paging resource indications of several groups of MTC devices can be aligned in such a way with the transmissions and re-transmissions by the network, that the different groups respectively receive the transmission and re-transmissions of the paging message.
