Abstract

See full text

A mobile station (MS) receive a higher layer signal including first information used for indicating a first downlink component carrier (DCC). MS transmits in a first subframe, HARQ control information using a first PUCCH and a first PUCCH format in a case that a first PDSCH transmission on a second DCC different from the first DCC is indicated by a detection of a first PDCCH in a second subframe. MS transmits in a third subframe, HARQ control information using a second PUCCH and a second PUCCH format in a case that a second PDSCH transmission only on the first DCC is indicated by a detection of a second PDCCH in a fourth subframe. First PUCCH format supports a number of information bits per subframe larger than a number of information bits per subframe supported by the second PUCCH format. First PUCCH format is used for transmitting HARQ control information with a scheduling request.
