Abstract: Disclosed is a communication method in a wireless communication system on the basis of a carrier aggregation. The communication method on the basis of a carrier aggregation comprises the steps of: receiving a PDSCH from a base station via a subframe n of a TDD cell; and transmitting, to the base station, a PUCCH including a response to the PDSCH via a subframe n+4 of an FDD cell. Accordingly, an HARQ process may be performed efficiently.

Abstract: Cell and terminal discovery methods are disclosed. A discovery method performed in a terminal may include transmitting a trigger signal; receiving a discovery signal from at least one cell which receives the trigger signal; measuring the discovery signal; and reporting a measurement result of the discovery signal to a serving cell. Therefore, cell and terminal discoveries may be performed efficiently in cellular mobile communication systems.

Abstract: Disclosed are methods for providing interference information in mobile communication systems. The method for providing interference information performed in a base station comprise obtaining information about at least one intra-cell interference signal interfering desired signals of a victim terminal, and transferring the information about at least one intra-cell interference signal to the victim terminal. In the method, the information about at least one intra-cell interference signal may include either information related to generation of reference signal for the at least one intra-cell interference signal or frequency resource allocation information and precoding matrix indicator (PMI) allocation information for the at least one intra-cell interference signal. Thus, the victim terminal may operate an advanced receiver based on the received information thereby canceling interferences efficiently.

Abstract: Disclosed is a method for directly transmitting and receiving data between terminals in a frequency division duplexing (FDD)-type and time division duplexing (TDD)-type mobile communication system. For FDD-type systems, provided are methods for performing direct data transmission and reception between terminals on the basis of a downlink subframe time interval and methods for performing direct data transmission and reception between terminals on the basis of an uplink subframe time interval. For TDD-type systems, provided are methods for performing direct data transmission and reception between terminals in a downlink subframe and methods for performing direct data transmission and reception between terminals in an uplink subframe. Additionally, for each method, provided are systems for performing only reception or transmission in one subframe and systems for performing both reception and transmission in one subframe.
