Abstract:
According to the disclosure of the present description, a method in which a base station determines a cooperative terminal is provided. The method comprises: a step of receiving status information from one or more terminals from among terminals that can cooperate with the base station in cooperative transmission; a step of determining, on the basis of the status information and upon receipt of a cooperative communication request from one terminal from among the cooperative terminals, a terminal which will cooperate with a terminal that has requested a cooperation; and a step of notifying the cooperative terminal of the terminal that has requested a cooperation.

Abstract:
Disclosed are a method for supporting device-to-device (D2D) communication in a cellular network, and an apparatus for same. The method for supporting device-to-device communication by a terminal in a cellular network comprises the steps of: the terminal receiving, from a base station, information on a D2D zone which has been set up for the D2D communication; and monitoring the D2D zone, using the information on the D2D zone, to detect a search signal transmitted by at least one D2D terminal, wherein the D2D zone may comprise: a search section for the transmission of the search signal by the at least one D2D terminal; and a connection section for transmission of a signal for requesting D2D transmission.
Abstract:
The present invention relates to a method for determining whether a mode change condition for performing a hand-over to a cellular network through which devices communicate with each other is satisfied, transmitting a mode change instruction message to a base station when the mode change condition is satisfied, receiving a mode change command message for starting a mode change from the base station, transmitting a first data packet index with respect to a data packet transmitted to a second device at a final stage through the communication between the devices to the base station, ending the communication with the second device when the inter-device communication end request message is received from the base station, and transmitting data to the second device through the cellular network.
Abstract:
Disclosed are a method for performing and supporting device to device direct communication (D2D communication) in a wireless communication system and a device therefor. The method for performing D2D communication of a terminal comprises the steps of: transmitting a first message, which is a request from a terminal operated in an idle state for connecting D2D communication and the base station, to a base station; and receiving a second message as a response to the request from the base station, wherein the second message includes a C-RNTI (Cell-Radio Network Temporary Identifier) allocated in the terminal to be connected with the base station, a D2D-RNTI (Device to Device RNTI) allocated in the terminal for D2D communication, and/or peer discovery configuration information.
Abstract:
The present invention relates to various methods for allocating and transmitting an enhanced physical downlink control channel, and apparatuses for supporting same. According to one embodiment of the present invention, a method for receiving an enhanced physical downlink control channel (E-PDCCH) in a wireless access system can comprise the steps of: receiving an E-PDCCH indication signal comprising information on the existence of an E-PDCCH signal and resource allocation information, which shows a resource region from which the E-PDCCH is transmitted; and receiving the E-PDCCH signal from the resource region that is shown by the resource allocation information, wherein the E-PDCCH indication signal can be transmitted from a legacy PDCCH region.

Disclosed are a device-to-device (D2D) data transmission method in a wireless access system supporting D2D communication and an apparatus therefor. According to one embodiment of the present invention, a D2D data transmission method in a wireless access system which supports D2D communication and cellular communication can comprise: a step in which a first device, which performs D2D communication with a second device, transmits first data to the second device only through a physical channel using an uplink of the cellular communication; and a step in which the first device receives second data from the second device through the physical channel.
Abstract:
A method of receiving downlink control information and a corresponding apparatus in a wireless access system supporting an enhanced physical downlink control channel. The method includes receiving, from an eNB, DCI transmission channel information that indicates which one of a physical downlink control channel (PDCCH) and the e-PDCCH is used to transmit the DCI, checking the starting symbol of the e-PDCCH when the DCI transmission channel information indicates that the e-PDCCH is used to transmit the DCI, and receiving the DCI by performing blind decoding on the e-PDCCH from the starting symbol of the e-PDCCH.
Abstract:
The present invention relates to a method for transmitting channel quality control information using two transmission blocks in a wireless access system that supports hybrid automatic retransmit request (HARQ). The method for transmitting channel quality control information according to one embodiment of the present invention comprises: a step in which a terminal receives a physical downlink control channel (PDCCH) signal including downlink control information (DCI); a step of calculating, using the DCI, the number (Q′) of encoded symbols required for transmitting channel quality control information; and a step of transmitting the channel quality control information via the physical downlink control channel (PDCCH) based on the number of encoded symbols.
Abstract:
