　RNTI is defined or set in accordance with the purpose and application of DCI. RNTI is, C-RNTI (Cell-RNTI), SPS C-RNTI (Semi Persistent Scheduling C-RNTI), SI-RNTI (System Information-RNTI), P-RNTI (Paging-RNTI), RA-RNTI (Random Access -RNTI), TPC-PUCCH-RNTI (Transmit Power Control-PUCCH-RNTI), TPC-PUSCH-RNTI (Transmit Power Control-PUSCH-RNTI), temporary C-RNTI, M-RNTI (MBMS (Multimedia Broadcast Multicast Services ) -RNTI), and, including eIMTA-RNTI, the CC-RNTI.
[0126]
　C-RNTI and SPS C-RNTI is a terminal device 2 in the base station apparatus 1 in the (cell) is a unique RNTI, an identifier for identifying the terminal device 2. C-RNTI is used to schedule the PDSCH or PUSCH in one subframe. SPS C-RNTI is used to periodic scheduling activation or release resources for PDSCH or PUSCH. Control channel having a scrambled CRC in SI-RNTI is used to schedule SIB (System Information Block). Control channel having a scrambled CRC in P-RNTI is used to control the paging. Control channel having a scrambled CRC in RA-RNTI is used to schedule a response to RACH. Control channel having a scrambled CRC in TPC-PUCCH-RNTI is used to perform the power control of the PUCCH.

It should be noted, is not limited to the above-mentioned RNTI, the DCI format by the new RNTI
[0127]
　Scheduling information (downlink scheduling information, uplink scheduling information, side links scheduling information), as the scheduling of the frequency domain, including information for performing scheduling resource block or resource block group to the unit. Resource block group is a set of contiguous resource blocks indicates the resources allocated for the terminal apparatus to be scheduled. The size of the resource block group is dependent on the system bandwidth.
[0128]
　　 DCI is transmitted using a control channel such as PDCCH or EPDCCH. Terminal device 2 monitors the one or more sets of PDCCH candidates Activating been serving cell and / or EPDCCH set of candidate set by RRC signaling. Here, the monitoring is to attempt to decode PDCCH and / or EPDCCH in the set corresponding to the DCI format to be all monitors.
[0129]
　Set of the set or the EPDCCH candidate of PDCCH candidates are also referred to as a search space. The search space, shared search space (CSS) and the terminal-specific search space (USS) is defined. CSS may be defined only for the search space on the PDCCH.
[0130]
　CSS (Common Search Space) is a search space that is set on the basis of specific parameters and / or predefined parameters to the base station apparatus 1. For example, CSS is a search space used in common by a plurality of terminal devices. Therefore, the base station apparatus 1 by mapping the common control channel by a plurality of terminal devices to CSS, resources for transmitting is reduced control channel.
[0131]
　USS (UE-specific Search Space) is a search space that is set using the parameters specific to at least the terminal device 2. Therefore, USS is a unique search spaces on the terminal device 2, the base station apparatus 1 can transmit individual-specific control channel to the terminal device 2 by USS. Therefore, the base station apparatus 1 can efficiently mapping specific control channels to a plurality of terminal devices.
[0132]
　USS may be set to be used in common to a plurality of terminal devices. For common USS is set to a plurality of terminal devices, parameters specific to the terminal apparatus 2 is set to be the same value among the plurality of terminal devices. For example, unit set to the same parameters between the plurality of terminal devices, cell, and the like transmission point or a group of a predetermined terminal device.
[0133]
　Search space of aggregation level each is defined by a set of PDCCH candidates. Each PDCCH, are transmitted using a set of one or more CCE (Control Channel Element). The number of CCE used for one PDCCH is also aggregation level is referred. For example, the number of CCE's used for one PDCCH is 1, 2, 4 or 8.
[0134]
　Search space of aggregation level each is defined by a set of EPDCCH candidate. Each EPDCCH, is transmitted using a set of one or more ECCE (Enhanced Control Channel Element). The number of ECCE used in one EPDCCH is also aggregation level is referred. For example, the number of ECCE used in one EPDCCH is 1,2,4,8,16 or 32.
[0135]
　Count of the number or EPDCCH candidates PDCCH candidates is determined based on at least the search space and aggregation level. For example, in CSS, the number of PDCCH candidates in aggregation level 4, and 8 are respectively 4 and 2. For example, in the USS, the number of PDCCH candidates in aggregation 1, 2, 4, and 8 are each 6,6,2 and 2.
[0136]
　Each ECCE is composed of a plurality of EREG (Enhanced resource element group). EREG is used to define the mapping for resource elements EPDCCH. In each RB pair are numbered from 0 to 15, 16 EREG is defined. That is, in each RB pair, EREG0 ~ EREG15 are defined. In each RB pair, EREG0 ~ EREG15, relative to resource elements other than resource elements in which a predetermined signal and / or channel is mapped, in favor of a frequency direction, is periodically defined. For example, resource elements EPDCCH demodulation reference signal associated with the transmitted on antennas ports 107-110 are mapped are not defined as EREG.
[0137]
　The number of ECCE used in one EPDCCH depends on EPDCCH format is determined based on other parameters. The number of ECCE used in one EPDCCH is also aggregation level is referred. For example, the number of ECCE used in one EPDCCH the number of resource elements which can be used for EPDCCH transmission in one RB pair based the like on the transmission method of EPDCCH, is determined. For example, the number of ECCE used in one EPDCCH is 1,2,4,8,16 or 32. The number of EREG used in one ECCE is determined based on the type and the type of cyclic prefix sub-frame, 4 or 8. Method of transmitting the EPDCCH, distributed transmission (Distributed Transmission) and localized transmission (the Localized Transmission) is supported.
[0138]
　EPDCCH may use distributed transmission or localized transmission. Distributed transmission and localized transmission, the mapping of ECCE is different for EREG and RB pair. For example, in a distributed transmission, one ECCE is constructed of a EREG multiple RB pairs. In localized transmission, one ECCE is constructed of a EREG one RB pair.

Also, settings for EPDCCH can be performed separately for each EPDCCH set.
[0140]
　The base station apparatus 1 to the terminal device 2, can be set EPDCCH set of a predetermined number. For example, EPDCCH set up to two, as EPDCCH set 0 and / or EPDCCH set 1 can be set. Each EPDCCH set, can be constituted by a predetermined number of RB pairs. Each EPDCCH set constitute one set of ECCE. The number of ECCE constructed in one EPDCCH sets, the number of RB pairs is set as the EPDCCH set, and, based on the number of EREG used in one ECCE, it is determined. If the number of ECCE constructed in one EPDCCH sets is N, each EPDCCH set constitutes the ECCE, numbered 0 ~ N-1. For example, when the number of EREG used in one ECCE is 4, the EPDCCH set composed of four RB pairs constituting 16 ECCE.
