Transmission device, receiving device, transmission method and receiving method

摘要

A base station (100) transmits a DL grant for a terminal (200) by mapping it to an R-PDCCH region, thus transmitting a series of data groups to the terminal (200) by the SPS method. A transmission control unit (102) sets in the R-PDCCH region a control resource region which maps a data resource and the DL grant in a resource block group common in frames to be transmitted by the SPS method.;A resource region which was defined as a control resource region in a first frame to be transmitted among a plurality of frames to be transmitted is defined as a data resource in a second or subsequent frame to be transmitted.

1. A transmission apparatus that maps control signals for a reception apparatus to a first resource region usable for a control channel or a data channel or to a second resource region usable for a control channel, transmits the mapped signals, and transmits a series of data to the reception apparatus while distributing the series of data to data resources in N transmission subframes to be transmitted consecutively with a predetermined frame interval therebetween, where N is a natural number greater than or equal to two, the transmission apparatus comprising:
a generating section that generates scheduling control signals for the data resources; a setting section that sets the data resources, and a control resource region to which the scheduling control signals are mapped in the first resource region in a resource block group (RBG); and a mapping section that maps the series of data to the set data resources and maps the scheduling control signals to the control resource region, wherein the setting section sets resource regions in the N transmission subframes such that the setting section sets the first resource region as the control resource region in the first transmission subframe of the N transmission subframes and sets the first resource region as the data resource in each of second to Nth transmission subframes subsequent to the first transmission subframe, the RBG is formed of M resource blocks (RBs), M being a natural number greater than or equal to two, and the RBG is common between the N transmission subframes, and the mapping section maps a downlink grant as the scheduling control signals to the first resource region set as the control resource region in the first transmission subframe, and maps downlink data to the first resource region set as the data resource in each of the second to Nth transmission subframes.
