摘要： Disclosed is a wireless communication base station apparatus whereby it is possible to prevent degradation of throughput of LTE terminals, even when LTE terminals and LTE+ terminals are present together. In this apparatus, a setting section (105) sets in each subframe a resource block in which is arranged a reference signal that is employed solely by LTE+ terminals, based on the pattern of arrangement of reference signals employed solely by LTE+ terminals. In the case of symbols that are mapped to antennas (110-1) to (110-4), an arrangement section (106) arranges the characteristic cell reference signals employed by both LTE terminals and LTE+ terminals in all of the resource blocks in a single frame. In contrast, in the case of the symbols that are mapped to the antennas (110-5) to (110-8), the arrangement section (106) arranges in some of the resource blocks, that are set in accordance with the setting results input from a setting section (105), the characteristic cell reference signals that are employed solely by the LTE+ terminals.

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 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.
