    摘要: In order to provide a transmission device and transmission method with which a response signal for random access preamble transmitted from a preamble transmission device is efficiently transmitted, base station (100) sets a first resource candidate group, which enables terminal (200) capable of receiving a latch response transmitted by demodulation reference signal (DMRS) transmission to be selected, and a second resource candidate group, which enables terminal (300) incapable of receiving a latch response transmitted by DMRS transmission but capable of receiving a latch response transmitted by cell-specific reference signal (CRS) transmission to be selected. Base station (100) selects DMRS transmission as the latch response transmission method when a resource in which latch preamble has been received is included in the first candidate group, but selects CRS transmission as the latch response transmission method when the resource is included in the second resource candidate group.

    摘要: This invention provides a terminal apparatus that can suppress the quality degradation caused by a propagation path variation when implementing a retransmission control method using non-adaptive HARQ in a wireless communication system utilizing the MIMO communication technique. In this apparatus, a number-of-retransmissions counting unit (105) counts a number of retransmission requests (L) for the same code word. A predetermined precoder designating unit (106) changes precoders between when the number of retransmission requests (L) is less than N and when the number of retransmission requests (L) is equal to or greater than N plus one. A PDCCH generation unit (211) determines, based on a result of comparison between the number of retransmission requests (L) for the same CW and the number of retransmission requests (N) established for the change of precoders, a precoder to be used by terminals, and further allocates, based on the determined precoder, resources to the plurality of terminals.

    摘要: Provided is a transmitter which improves the flexibility of SRS resource allocation without increasing the amount of signaling for notifying the cyclic shift amount. In the transmitter, with regard to each basic shift amount candidate group having a basic shift amount from 0 to N−1, a transmission control unit (206) specifies the actual shift amount imparted to a cyclic shift sequence used in scrambling a reference signal transmitted from each antenna port, said specification being performed based on a table in which cyclic shift amount candidates correspond to each antenna port, and based on setting information transmitted from a base station (100). With regard to basic shift amount candidates for shift amount X, the table differentiates between an offset pattern comprising offset values for cyclic shift amount candidates corresponding to each antenna port and an offset pattern corresponding to basic shift amount candidates of X+N/2.
