Provided are a discovery method and apparatus. A communication method for a user equipment (UE) may include: receiving first resource information indicating a first resource region and second resource information indicating a second resource region from an evolved Node B (eNB); receiving a first message from a second UE via the first resource region; checking whether the contents of the first message match the UE; and sending, when the contents of the first message match the UE, a second message associated with the first message to the second UE via the second resource region. A user equipment (UE) may include: a communication unit configured to receive first resource information indicating a first resource region and second resource information indicating a second resource region from an evolved Node B (eNB), and receive a first message from a second UE via the first resource region; and a control unit configured to check whether the contents of the first message match the UE.
Abstract:
The present invention relates to a method and an apparatus for transmitting data to user equipment through not only a current base station cell but also a neighboring base station cell via inter-eNB CA in a wireless communication system. A method for transmitting data though carrier aggregation in the wireless communication system, according to the present invention, comprises the steps of: a first base station transreceiving data with a terminal through at least two PDN connections; the first base station transmitting a carrier aggregation request message to a second base station for aggregating carriers, when the first base station determines to carry out inter-eNB carrier aggregation; the first base station receiving a carrier aggregation reply message from the second base station in response to the carrier aggregation request message; the first base station performing an RRC reconfiguration process with the terminal to notify to the terminal of the determination to perform the inter-eNB carrier aggregation; and the first base station transmitting a path change request message to a mobile management entity to correct a data transreceiving path, so that data on at least one PDN connection from among the PDN connections is transreceived through the second base station.

A method and apparatus for performing a device-to-device (D2D) communication by a user equipment and supporting D2D communication by a communication entity. The D2D communication method may include: acquiring ProSe ID of the UE or the UE's user, which is used in the D2D communication; generating an expression by using the ProSe ID; broadcasting the generated expression; receiving a direct D2D connection request message from another UE over a core network; sending a direct connection accept message in response to the direct D2D connection request message; and performing the D2D communication with another UE. Accordingly, D2D communication can be efficiently performed.
