    摘要： When a transport block size (TBS) of a downlink shared channel is determined based on a modulation scheme that is adaptively controlled, a user terminal can appropriately receive and/or decode the downlink shared channel. The user terminal according to the present invention includes: a reception section that receives a downlink shared channel; and a control section that obtains a transport block size (TBS) used for the downlink shared channel based on a TBS index value and a number of resource blocks (RB), where the TBS block size index value is associated with a modulation and coding scheme (MCS) index valued used for the downlink shared channel, and the RBs are allocated to the downlink shared channel, and, when the downlink shared channel is transmitted by a specific transmission scheme and the MCS index value is a specific value, the TBS index value associated with the specific value is changed and the control section obtains the TBS based on the changed TBS index value and the number of RBs.

    摘要： Even when a same C-RNTI is allocated to multiple mobile stations UE in a phantom cell, a collision between the mobile stations UE to which the same C-RNTI is allocated is avoided. A radio base station PhNB#10 according to the present invention includes an allocation unit 11 configured to allocate a same C-RNTI ph to multiple mobile stations UE#1 to UE#3 in a cell #10 and a transmission unit 13 configured to notify the multiple mobile stations UE#1 to UE#3 of different locations of radio resources. The transmission unit 13 transmits control signals to the mobile stations UE#1 to UE#3 at the notified locations of the radio resources through a PDCCH using the same C-RNTI ph .

    摘要： The present invention is designed to provide a radio communication terminal, a base station apparatus, a radio communication system and a radio communication method which can reduce the cost to be required for an MTC terminal when the LTE system is employed in the network domain of a machine communication system. A radio communication terminal according to the present invention is a radio communication terminal that performs machine communication via a base station apparatus of a radio communication system that is operated such that a frequency becomes the first band at a maximum, depending on the performance which a communication device supports, and has a receiving section that has receiving performance to be able to support the first band, and that decodes the entire band of the first band at least with respect to a time domain where a downlink control channel is allocated, and a transmission section that has transmission performance to be able to support a second band having a narrower bandwidth than the first band, and that allocates an uplink control channel and an uplink data channel to the second band.

    摘要： A C-RNTI ph in a phantom cell is allocated to a mobile station UE after the mobile station UE is identified. A mobile communication method according to the present invention includes the steps of : when a cell #10 formed by linking multiple small cells is established in a manner as to at least partially overlap a coverage area of a cell #1 under control of a radio base station eNB#1, notifying a mobile station UE#1 in communication in the cell #1 of a C-RNTI ph in the cell #10 by the radio base station eNB#1 by sending "RRC connection reconfiguration"; and setting, by the mobile station UE#1, the C-RNTI ph in the cell #10 in addition to a C-RNTI macro in the cell #1.
