    Abstract: The present invention relates to methods and apparatuses for supporting or controlling a small cell on or off procedure. The method may comprise steps of receiving, by the MSC from a Source Small Cell (SSC), a Cell Off Indication message including a Cell State Change Indication parameter indicating a cell status of the SSC; transmitting, by the MSC to the SSC, an Expand Indication message indicating an expanding of the MSC when the Cell State Change Indication parameter indicates a cell off status, the Expanding Indication message including a Time to Start Expand parameter indicating when the MSC starts an expanding of its coverage and an Expand Timer parameter indicating a time period during which the expanding is performed; and starting the expanding of its coverage at a time indicated by the Time to Start Expand parameter during the time period indicated by the Expand Timer.

    Abstract: Disclosed are a method for reporting buffer status for device-to-device (D2D) communication and an apparatus therefor. The method for reporting buffer status in a radio communication system that supports D2D communication comprises: setting up, by a first D2D terminal, a media access control (MAC) packet data unit (PDU) including an ID for a D2D link with a second D2D terminal, in order for D2D buffer status reporting (BSR), if the first D2D terminal is supposed to transmit data to the second D2D terminal; and transmitting the MAC PDU from the first D2D terminal to a network.

    Abstract: A method for performing, by a station (STA) apparatus, uplink (UL) multi-user (MU) transmission in a wireless communication system according to an embodiment of the present invention includes performing carrier sensing on a channel, receiving a trigger frame including information for UL MU transmission and a carrier sense indicator indicating whether a result of the carrier sensing is to be reflected from an access point (AP), and transmitting an UL MU frame through the channel based on the information for UL MU transmission. The UL MU frame is transmitted through the channel based on a result of the carrier sensing if the carrier sense indicator indicates the reflection of a result of the carrier sensing. The UL MU frame is transmitted through the channel regardless of a result of the carries sensing if the carrier sense indicator does not indicate the reflection of a result of the carrier sensing.

    Abstract: A method for performing uplink Orthogonal Frequency Division Multiple Access (UL OFDMA) based random access to an Access Point (AP) by a Station (STA) in a Wireless Local Area Network (WLAN) system is proposed. For the purpose, the STA sets a random value within an OFDMA Contention Window (CWO) as an OFDMA Back-Off (OBO) value, receives a beacon frame from the AP, the beacon frame including transmission start time information of one or more Trigger Frames for Random Access (TF-Rs), decrements the OBO value based on reception of the one or more TF-Rs, and if the OBO value reaches 0, transmits a random access request frame in resources selected randomly from among resources allocated to the STA.

    Abstract: Provided is a method for transmitting and receiving inter-cell information for cancelling inter-cell interference in a wireless communication system. The method for transmitting and receiving inter-cell information may comprise the steps in which: a base station of a victim cell transmits, to a base station of an adjacent aggressor cell, a first PMI set which is a set of PMIs of a signal corresponding to an area partitioned in a predetermined direction; the base station of the aggressor cell transmits, to the victim cell, the signal of the PMIs by using a specific resource; the base station of the victim cell receives, from a terminal in the victim cell, a feedback signal on the signal of the PMIs; the base station of the victim cell transmits, to the base station of the aggressor cell, the feedback information; and the base station of the aggressor cell updates the first PMI set to a second PMI set on the basis of the feedback information, and transmits, to the base station of the victim cell, the updated second PMI set.
