摘要： A terminal of a communication system transmits a first signal through a physical uplink channel that is allocated within a first radio resource based on a first Transmission Time Interval (TTI) having a first time length at a first step for uplink access, performs the remaining steps for the uplink access using a second radio resource based on the second TTI from a base station, when the terminal may operate based on a second TTI having a second time length smaller than the first time length, and transmits uplink data.

摘要： Provided are a method and an apparatus for performing a synchronous hybrid automatic repeat reQuest (HARQ). When a variable transmission time allocation is allocated per HARQ process, resource allocation information including a duration field corresponding to a length of a transmission time interval (TTI) allocated to each of the HARQ processes is transmitted. After the resource allocation information is transmitted, it is determined whether an HARQ error occurs at a predetermined timing and if it is determined whether the HARQ error occurs, the HARQ error is handled.

摘要： Disclosed is a method and apparatus for random access in a wireless communication system. In a communication environment in which a first terminal and a second terminal coexist, a base station receives a random access identification signal from one among a first terminal and a second terminal. The base station transmits a busy signal in response to the random access identification signal. After that, the base station receives data from the terminal having transmitted the random access identification signal.

摘要： A discovery method is provided by a device in a D2D direction communication. The device selects a discovery resource unit from among discovery resource units which are not being used after listening during one or more discovery resource periods. The device transmits a first discovery signal through the selected discovery resource unit in a broadcasting manner at a first discovery resource period, and transmits a second discovery signal through the selected discovery resource unit in a query-based manner at a second discovery resource period.
