Abstract: Provided is a method and an apparatus for transmitting a random access preamble in a time division duplex (TDD)-based wireless communication system. A wireless device selects an UL subframe in which a random access preamble is to be transmitted in a first serving cell. If the next subframe following the selected UL subframe is a DL subframe and the length of the random access preamble exceeds the UL subframe, the random access preamble may be generated such that the length of the random access preamble may not exceed the UL subframe.

Abstract: A method and a communication apparatus for transmitting uplink control information in a wireless communication system using time division duplex (TDD). The method according to an embodiment includes receiving at least one physical downlink control channel (PDCCH) or at least one physical downlink shared channel (PDSCH); and generating reception response information for the at least one PDCCH or the at least one PDSCH. When the reception response information and channel status information are configured to be transmitted in a same subframe and a first physical uplink control channel (PUCCH) format is configured for the communication apparatus, if a certain condition is satisfied, the reception response information and the channel status information are transmitted together using a second PUCCH format. The certain condition includes a first condition of a single PDSCH transmission only on a primary cell (PCell) where there is not a corresponding PDCCH being present.
