摘要： It is possible to provide a radio communication base station device, a radio communication relay station device, a radio communication terminal device, a radio communication system, and a radio communication method which can minimize a delay and effectively use resources. When a terminal starts an uplink communication with a base station via a repeater, [ST403] a base station transmits to a repeater, Grant 1 for the base station to allocate an initial transmission resource to the terminal and Multi-direction Grant which can be applied either to retransmission from the terminal to the repeater or the relay from the repeater to the base station, and [ST404] the Grant 1 and the Multi-direction Grant are relayed to the terminal.

摘要： It is possible to provide a radio communication relay device, a radio communication base station device, a radio communication system, and a radio communication method which can effectively use resources and suppress a data delay and system complexity. When a terminal starts an upstream communication with a base station via a repeater in ST403, the base station simultaneously allocates to the terminal, a resource for an initial transmission and a resource for a retransmission by using Grant 1. If the repeater successfully receives UL data transmitted from the terminal in ST404, the repeater relays, in ST406, the UL data transmitted from the terminal, to the base station by using the resource for retransmission which has been allocated to the terminal.

摘要： There are provided a communication device, a base station, a communication system, and a communication method that make it possible to yield a diversity effect by cooperative relay without involvement of disproportionateness in data received by an eNB even when one of parties has unsuccessfully exchanged data. After received an ACK signal from a repeater 1, a repeater 2 which has transmitted a NACK signal in procedure 7 transmits data S2 to the eNB by use of its own resource, thereby making its own resource available for the repeater 1 (the repeater 2 does not use its own resource, and the repeater 1 uses the resource of the repeater 2). In procedures 8, the repeater 1 has received the NACK signal from the repeater 2 and subsequently transmits data S1 to the eNB by use of its own resource. Subsequently, the repeater 1 which has received the MACK signal in procedure 9 determines that the resource of the repeater 2 is available and transmits data P1 to the eNB by use of the resource of the repeater 2. In procedure 10, the repeater 1 transmits previously-generated data P2 to the eNB by use of its own resource.

摘要： A wireless relay station apparatus for enabling a mobile station and a base station to reliably receive network coding data and to provide sufficient reception performance is provided. (1) A repeater divides data X received from a mobile station into important data and non-important data and divides data Y received from eNB into important data and non-important data. Next, (2) the repeater places the data so that important data Sx for the mobile station and important data Sy for the eNB do not overlap, XORs (exclusive ORs) them, and generates network coding data X (X) Y. (3) The repeater applies downlink propagation inverse characteristic H1−1 to important data portion Px (X) Sy for the mobile station and on the other hand, applies uplink propagation inverse characteristic H0−1 to important data portion Sx (X) Py for the eNB in the network coding data X (X) Y for transmission.

摘要： A base station device causing no decrease in system throughput and guaranteeing the reception quality at a terminal when a DCI directed toward the terminal is mapped to a PDCCH region and an R-PDCCH region. A search space setting unit (103) sets a search space having a plurality of allocation candidates, in both regions. An allocation unit (106) allocates control information to a resource in one allocation candidate in the search space. The ratio of the number of allocation candidates in the R-PDCCH region to the number of allocation candidates in the PDCCH region in the search space for a terminal using DM-RS in the R-PDCCH region is equal to or greater than the ratio of the number of allocation candidates in the R-PDCCH region to the number of allocation candidates in the PDCCH region in the search space for a terminal using CRS in the R-PDCCH region.

摘要： There are provided a wireless communication apparatus, a wireless communication method, and a wireless communication system capable of selectively utilizing the advantages of both centralized control and distributed control while a time needed for cell searching is suppressed. FIG. 4(a) represents an example in which a P-BCH and an S-SCH for the centralized control and a P-BCH and an S-SCH for the distributed control are frequency-divided, and the P-BCH and the S-SCH for the distributed control are transmitted to a distributed control resource. FIG. 4(b) represents an example in which a P-BCH and an S-SCH for the centralized control and a P-BCH and an S-SCH for the distributed control are time-divided, and the P-BCH and the S-SCH for the distributed control are transmitted to a centralized control resource. Since a relay station transmits the P-SCH as a centralized control resource, a mobile station can specify sub-frame timing by using only the centralized control resource.

摘要： The error rate characteristic in a wireless communication apparatus for relaying communications between a mobile station and a base station is improved. For the modulation level of the resource for network coding, the modulation level from a relay station to the mobile station or the modulation level from the relay station to the base station, whichever is lower, is selected and thus the modulation level becomes QPSK. The relay station preferentially assigns S1 of a systematic bit of high importance, of S1+P1 to the network coding resource. The signal of S1+P1 not assigned to the network coding resource is assigned to the resource for the base station from the relay station. In the example, S1 is assigned to the resource for network coding and P1 is assigned to the resource for the base station from the relay station.

摘要： A wireless communication apparatus wherein the buffer size can be reduced without increasing the overhead of signalings. In this apparatus, a buffer (201) stores transport data. A radio receiving part (206) receives a response signal responsive to a transport data transmitted by the local apparatus; a response signal responsive to a transport data transmitted by another wireless communication apparatus; and relay data. A determining part (208) determines the smaller one of the two numbers: the number of ACK signals responsive to the transport data transmitted by the local apparatus and the number of ACK signals responsive to the transport data transmitted by the other wireless communication apparatus. The buffer (201) deletes transport data the number of which is equal to the difference between the number of ACK signals responsive to the transport data transmitted by the local apparatus and the number determined by the determining part (208). A network decoding part (209) uses both the relay data and the transport data stored in the buffer (201) to perform a network decoding, thereby acquiring data signals transmitted by the other wireless communication apparatus.
