Abstract: A terminal executes a random access procedure with a target base station depending on a pre-random access channel (pre-RACH) command in a handover preparation step executed between a source base station currently accessed by the terminal and the target base station when the terminal receives the pre-RACH command from the source base station through layer2 (L2) signaling in the handover preparation step.

Abstract: 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.

Abstract: 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.

Abstract: Disclosed herein are a method and an apparatus for a buffer status report in a mobile communication system. The method for a buffer status report includes setting a new QoS class identifier (QCI) value for supporting a radio bearer (RB) added for a low latency service; and allocating a logical channel of a RB for an existing service and a logical channel of a RB for the low latency service to logical channel groups (LCGs) in consideration of the newly set QCI value. Further the buffer status report for each logical channel performed in an LCG unit is received.

Abstract: 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.
