    Abstract: Provided are a method and device for transmitting control information in a wireless communication system. In particular, a downlink resource block group including a downlink resource block in a downlink frequency bandwidth is set, and an uplink resource block group including an uplink resource block in an uplink frequency bandwidth is set. If the downlink frequency bandwidth is smaller than the uplink frequency bandwidth, the downlink resource block group is mapped to the uplink resource block group. The ratio of the number of uplink resource blocks to the number of downlink resource blocks is set so that the number of uplink resource block groups and the number of downlink resource block groups become the same. The uplink and downlink resource block groups are mapped according to the ratio. Control information on the mapping is transmitted through the downlink resource block groups.

    Abstract: A method for a terminal out of a coverage to establish multi-links via relay terminals in a wireless communication system, according to one embodiment of the present invention, comprises the steps of: sending an RRC connection request to a temporary relay terminal having the most excellent device to device (D2D) signal quality, among relay terminals located nearby the terminal; receiving, from the temporary relay terminal, an RRC connection setup indicative of a first base station to provide a substitution link, from among the base stations to which the relay terminals are connected; establishing the serving link via a first relay terminal by sending an RRC connection completion message to the first relay terminal connected to the first base station, from among the relay terminals; and establishing the substitution link in which unicast data transmission/reception is deactivated, via the second relay terminal connected to the second base station, from among the relay terminals.

    Abstract: Provided are a method and device for performing communication using a plurality of subframes in a time division duplex (TDD) based wireless communication system. Specifically, groups are set by grouping a first configuration and a second configuration which arrange at least one downlink symbol and at least one uplink symbol in a subframe unit. The first configuration and the second configuration are configured in a manner that the downlink symbol and the uplink symbol do not overlap with each other in a particular symbol interval. Information indicative of a group is transmitted to a terminal for at least one subframe from among the plurality of subframes. Information indicative of a configuration to be used in the terminal of the first configuration and the second configuration in a group with respect to at least one subframe is transmitted to the terminal.

    Abstract: The present invention relates to a wireless access system supporting a millimeter wave (mmWave), and provides methods for performing a fast fallback in order to avoid a link disconnection and devices supporting the same. As an embodiment of the present invention, a method for performing a fast fallback by a terminal in a wireless access system supporting a millimeter wave (mmWave) may comprise the steps of: establishing radio resource control (RRC) connections with a mmWave base station and a legacy base station, respectively; receiving downlink data transmitted from the mmWave base station; receiving, from the legacy base station, resource-related information associated with a resource to be allocated for a fast fallback; detecting whether a non-light of sight (NLoS) transition occurs in a mmWave link with the mmWave base station; and when the NLoS transition occurs, transmitting a fallback request message to the legacy base station in order to perform the fast fallback.
