Abstract: A method includes determining a payload size of a first downlink control information (DCI) format that is the same as a payload size of a second DCI format. The first DCI format is for scheduling an uplink carrier and carries a first carrier indication and the second DCI format is for scheduling a downlink carrier and carries a second carrier indication. The first carrier indication is different from the second carrier indication. The method also includes monitoring DCI in the first DCI format.
