Abstract: Provided are a radio transmission apparatus and a radio transmission method whereby the increase of number of signaling bits can be suppressed and further the flexibility of frequency scheduling can be improved. A notified RBG calculating unit (203) that adds a predetermined offset value of "1" or "-1" to one of the start RBG number and the end RBG number of allocated RBG number information (b'i) output by a scheduling unit (201), thereby calculating notified RBG number information (bi). An RBG total number setting unit (204) calculates the total number of RBGs, which is to be notified, by adding "1" to the total number of allocated RBGs. A notified information generating unit (205) applies the notified RBG number information (bi) and the notified total number of RBGs (Nrb') to a predetermined formula, thereby generating and transmitting, to terminals, notified information (r).

Abstract: Disclosed are a wireless communication base station device and a division number determination method that improves the frequency diversity effect while maintaining channel estimation accuracy regardless of the number of divisions in the frequency domain of a transmission signal from a wireless communication terminal device. A determination unit (117) determines the number of divisions in the frequency domain of a transmission signal from a wireless communication terminal device. Here, the determination unit (117) increases the number of divisions in the frequency domain of the transmission signal from the wireless communication terminal device as the number of pilot blocks included in the transmission signal increases. In addition, a scheduling unit (118) schedules allocation to the frequency resources of the divided transmission signal according to the number of divisions determined by the determination unit (117).

Abstract: Provided are a wireless communication terminal apparatus, a radio communication base station apparatus and a wireless communication method whereby the increase in the number of signaling bits can be suppressed, while the SRS capacity can be improved. RS type determining unit (105) determines, based on scheduling information, that the signal is an SRS signal accompanied by no data or a DMRS signal accompanied by data. CS amount deciding unit (106) holds a CS amount for DMRS and a CS amount for SRS that are defined such that the CS amount for SRS includes a CS amount not included in the CS amount for DMRS. The CS amount deciding unit (106) uses CS amount notification information, which is included in the scheduling information, and the CS amount definition to derive a CS amount in accordance with the RS type outputted from the RS type determining unit (105).

Abstract: A scheduling apparatus and a scheduling method, wherein the amount of signaling for frequency resource allocation information can be reduced while maintaining system throughput performance. In a base station apparatus (100), a scheduling section (113) allocates frequency resources to frequency allocation target terminals based on set frequency allocation units, and a frequency allocation parameter setting section (112) adjusts the set frequency allocation units set in the scheduling section (113) based on cluster numbers. Due to this, in each cluster number, frequency resources can be allocated based on the most suitable frequency allocation units with respect to the signaling bit number. As a result, the amount of signaling for frequency resource allocation information can be reduced. Further, system throughput can be maintained by making the cluster number, which is a parameter having little effect on system throughput, a setting parameter for frequency allocation units.

Abstract: A terminal device is equipped with: a sequence determination unit that determines a sequence number with a different pattern than the assignment pattern for the sequence number assigned to the cell in which the host device resides; a reference signal generation unit that generates a reference signal for a sequence group corresponding to the sequence number that has been determined; and a wireless transmission unit that transmits the reference signal that has been generated to a base station. The sequence determination unit employs a configuration whereby, with the sequence number assigned to the cell in which the host device resides as a cell-specific sequence number, a dynamic offset which periodically changes over time and for which the same value is not consecutive is added to the cell-specific sequence number, thereby determining a sequence number which never overlaps with the cell-specific sequence number.

Abstract: Provided is a terminal apparatus that can suppress the increase in interference between pilot signals in the same slot, while also suppressing the degradation of the flexibility to design cell cluster structures. When hopping information indicates an inter-slot hopping, a mapping unit (212) arranges a first pilot sequences in which a group to which the sequences used in respective slots belong varies on a slot-by-slot basis. When the hopping information indicates an inter-subframe hopping, the mapping unit (212) arranges a second pilot sequences in which a group to which the sequences used in respective slots belong varies on a subframe-by-subframe basis. The sequence group to which the sequences used in any one of the subframes in the second pilot sequences belong is identical with the sequence group to which the sequence used in any one of the slots included in that one subframe in the first pilot sequences belongs.

Abstract: Provided are wireless communication methods for D2D communication and UEs therefor. A wireless communication method involves transmitting either a first DCI or a second DCI based on whether a first UE and a second UE are to be in a communication type of groupcast or unicast. In the wireless communication methods, the first DCI and the second DCI are scrambled by the UE ID of the second UE if the first UE and the second UE are in the communication type of unicast upon transmitting the first DCI and the second DCI, and the first DCI and the second DCI are scrambled by the group ID if the first UE and the second UE are in the communication type of groupcast upon transmitting the first DCI and the second DCI.
