RADIO TERMINAL, RADIO BASE STATION, CHANNEL SIGNAL FORMING METHOD AND CHANNEL SIGNAL RECEIVING METHOD Russian patent published in 2014 - IPC H04W72/04 

FIELD: radio engineering, communication.

SUBSTANCE: invention relates to communication engineering. In a base station (100), an information size adjustment unit (103) uses, in a common search space in a downlink additional unit band, the larger of the information size of downlink allocation control information determined from the bandwidth of a downlink additional unit band and the information size of uplink allocation control information determined from the bandwidth of an uplink unit band associated with the downlink additional unit band by a broadcast channel signal transmitted in the downlink additional unit band, as a size adjustment reference, and uses, in a UE specific search space, the larger of the information size of the downlink allocation control information determined from the bandwidth of the downlink additional unit band and the information size of the uplink allocation control information determined from the bandwidth of the uplink unit band of a unit band group, as the size adjustment reference.

EFFECT: radio terminal, radio base station, channel signal forming method, and channel signal receiving method are provided, by which the number of blinds in the processing for receiving allocation control information is reduced without causing disadvantages associated with the reception of a broadcast channel signal.
