FIELD: radio engineering, communication.SUBSTANCE: invention relates to wireless communication and is intended for transmitting uplink control information while indicating the transmission mode for control information. The invention particularly discloses a base station which includes transmission path circuits for selecting one of a first UCI multiplexing method, which allows a subscriber station to simultaneously transmit PUSCH and PUCCH, and a second UCI multiplexing method which does not allow a subscriber station to simultaneously transmit PUSCH and PUCCH. The transmission path circuits also transmit an upper layer signal which indicates one selected UCI multiplexing method and transmits one or more uplink grants. Each of the uplink grants schedules a PUSCH in an UL CC for a subframe n, and each of the uplink grants carries a CQI request. The base station also includes reception path circuits for receiving an aperiodic CSI report on the PUSCH on the uplink component carrier i when only one of the uplink grants scheduling a PUSCH on an uplink component carrier i carries a CQI request having a value from a set of values.EFFECT: improved communication quality.14 cl, 16 dwg, 3 tbl |
