Abstract: A method for transmitting a downlink in an unlicensed band is provided. A plurality of base stations in a first group determine a first delay time from a reference time point for initiating a clear channel assessment (CCA) in the unlicensed band. The plurality of base stations execute CCA during a CCA section after the first delay time from the reference time point, and check whether a channel is idle. If the channel is idle, the plurality of base stations simultaneously transmits a downlink.

Abstract: A base station (BS) operated in an unlicensed band configures a first energy detection threshold for a discovery signal and a second energy detection threshold for data, and performs energy detection. The BS transmits the discovery signal to a user equipment in the unlicensed band if a detected energy based on the energy detection is less than the first energy detection threshold. Further, the BS transmits the data to the user equipment in the unlicensed band if the detected energy based on the energy detection is less than the second energy detection threshold. The first energy detection threshold for the discovery signal is higher than the second energy detection threshold for the data.

Abstract: A method for transmitting an uplink control signal of a terminal in a wireless communication system and a terminal using the method are provided. The method comprises the steps of: setting a first physical uplink control channel (PUCCH) resource for a first antenna port; setting a second PUCCH resource for a second antenna port; and transmitting a same uplink control signal through the first and second antenna ports by using the first and second PUCCH resources, wherein the first and second PUCCH resources are orthogonal to each other.

Abstract: Provided are a method and a device for reporting a power headroom in a wireless communication system. The device receives initial downlink control information (DCI) for physical uplink shard channel (PUSCH) transmission in a first subframe and receives triggering DCI in a second subframe. The device calculates a power headroom on the assumption that the PUSCH transmission is not performed.

Abstract: A method and apparatus for allocating resources to a low cost user equipment (UE) in a wireless communication system is provided. A base station (BS) allocates at least one sub-bandwidth among a system bandwidth to a low cost UE, and transmits information on the allocated at least one sub-bandwidth to the low cost UE. The at least one sub-bandwidth may include a set of resource physical resource blocks (PRBs) that the low cost UE can access at a given subframe.

Abstract: The present invention relates to, in a wireless access system supporting an unlicensed band, methods for configuring and scheduling a partial subframe (pSF) and devices for supporting same. A method for receiving data through a cell (U cell) configured in an unlicensed band in a wireless access system for supporting an unlicensed band comprises the steps of: a terminal receiving control information from a base station through a primary cell (P cell) which is configured in a licensed band; and the terminal receiving, on the basis of the control information, downlink data from the base station through an unlicensed band cell (U cell) which is configured in an unlicensed band, wherein, if cross-carrier scheduling is configured in the terminal, the terminal not anticipating, as the subframe for receiving the downlink data, a partial subframe (pSF) which is transmitted in a state of having the first part of symbol emptied, wherein the pSF is configured to be smaller than one subframe.
