WIRELESS COMMUNICATION TERMINAL DEVICE, WIRELESS COMMUNICATION BASE STATION DEVICE AND RESOURCE REGION SETTING METHOD Russian patent published in 2013 - IPC H04W72/04 

FIELD: radio engineering, communication.

SUBSTANCE: terminal (200), wherein a PCFICH reception unit (208) obtains CFI information indicating the number of symbols used for a control channel to which resource allocation information relating to downlink data addressed to a device is allocated for each of the downlink component bands, a mapping unit (214) sets a resource region to which an acknowledgment signal to the downlink data is allocated for each of the plurality of downlink component bands according to the CFI information of each of the downlink component bands in an uplink component band set to the device, and maps the acknowledgment signals into the resource regions corresponding to the downlink component bands used for the allocation of the downlink data.

EFFECT: reducing resource regions in an uplink component band without increasing signalling even if a plurality of acknowledgment signals to downlink data transmitted respectively in a plurality of downlink component bands are transmitted from one uplink component band.
