Abstract: Provided are a method and apparatus for requesting scheduling for an uplink data transmission in a wireless communication system. The method may include receiving, by a user equipment, an additional scheduling request (SR) resource configuration information including additional SR resource information and buffer size information configured to the additional SR resource in addition to a default SR resource from a base station, transmitting, by the user equipment, an SR through the default SR resource or the additional SR resource to the base station, receiving, by the user equipment, an uplink resource allocation information which is determined according to the resource in which the SR is transmitted from the base station, and transmitting, by the user equipment, the uplink data to the base station through a physical uplink shared channel (PUSCH) resource which is allocated by the uplink resource allocation information.

Abstract: Provided according to the present invention is a method for a first neighbor awareness networking (NAN) device for performing service discovery in a wireless communication system. A method for performing service discovery comprises the steps of: exchanging a subscribe message with a second NAN device; and transmitting a first service discovery frame (SDF) on the basis of the exchanged subscribe message. The first service discover frame comprises a NAN connection capability attribute field, wherein the NAN connection capability attribute field comprises a first type interface information field, wherein the first type interface information field can show whether or not the first NAN device supports a first type interface.

Abstract: A method and a device for positioning a NAN terminal in a wireless LAN system are provided. A first station receives, through a service discovery frame during a preset discovery window, allocation information of an available window for reporting a location estimate value of the first station, location information of a second station located within a distance of one hop from the first station, and location information of a third station located within a distance of at least one hop from the second station. The first station determines the location estimate value of the first station on the basis of the location information of the second station and the location information of the third station. The first station reports the location estimate value of the first station during a section indicated by the allocation information of the available window.
