Abstract:
An embodiment of the present invention relates to a method of transceiving a neighbor awareness networking (NAN) signal by a NAN device in a wireless communication system, the method comprising the steps of: receiving a NAN publish from an access point (AP); identifying a service from the NAN publish; and having association with the AP for the identified service, wherein the service is one of services of one or more stations (STAs) associated with the AP.
Abstract:
One embodiment of the present invention relates to a method for transreceiving signals through a neighbor awareness networking (NAN) terminal in a wireless communication system, comprising the steps of: receiving a NAN synchronization beacon frame and/or a NAN discovery beacon frame; and accessing a NAN cluster which has transmitted the NAN discovery beacon frame, wherein when the NAN cluster is a coordinated NAN cluster, the NAN terminal maintains the state at the time of accessing the NAN cluster.
Abstract:
A wireless communication system is disclosed. Disclosed herein are methods for transmitting a physical uplink control channel (PUCCH) signal in a wireless communication system, which includes setting transmit power for the PUCCH signal, and an apparatus thereof. If the PUCCH signal is transmitted on a subframe configured for a scheduling request (SR), the PUCCH signal includes one or more hybrid automatic repeat request acknowledgement (HARQ-ACK) bits and an SR bit. When determining the transmit power for the PUCCH, the SR bit is selectively considered depending on whether or not a transport block for an uplink shared channel (UL-SCH) is present in the subframe.
Abstract:
Disclosed are a method by which a NAN terminal participates in a NAN cluster and a NAN terminal device therefor. The method by which a NAN terminal participates in a NAN cluster, according to the present invention, can comprise the steps of: searching for a NAN cluster; and receiving a NAN beacon frame from any one of a plurality of NAN clusters if the plurality of NAN clusters are retrieved. Here, if the number of hops to an anchor master indicated by the received NAN beacon frame is larger than a threshold value, the NAN terminal is capable of receiving the NAN beacon frame from the other one of the plurality of NAN clusters.
Abstract:
Disclosed are a method and an apparatus capable of searching for a docking service and a peripheral function incidental to the docking service in a direct communication system. To this end, a method by which a first wireless device searches for a peripheral function provided by a second wireless device can comprise the steps of: transmitting a probe request frame to the second wireless device by the first wireless device; and receiving a probe response frame from the second wireless device as a response to the search request, wherein the probe response frame can include a bitmap for indicating a name of the peripheral function supported by the second wireless device or the peripheral function supported by the second wireless device.
Abstract:
One embodiment of the present invention relates to a method for shifting the state of a neighbor awareness networking (NAN) terminal in a wireless communication system, comprising the steps of: receiving a first synchronization beacon frame; and receiving a second synchronization beacon frame after the first sync beacon frame has been received, wherein the state of the NAN terminal is shifted to a state capable of transmitting synchronization beacon frames regardless of a received signal strength indicator (RSSI) of the synchronization beacon frames, when anchor master rank information included in the first synchronization beacon frame and anchor master rank information included in the second synchronization beacon frame are different, and the NAN terminal is in a non-master non-sync state.
Abstract:
The present invention relates to a wireless communication system. More particularly, the present invention relates to a method for transmitting, if an advertiser device is set to delay a session with respect to the request for a session from a seeker device, session delay information to the seeker device in a method for setting Wi-Fi direct service communication and to an apparatus therefor.
Abstract:
The present invention relates to a wireless communication system, and provides a method and apparatus for remotely controlling another device in a direct communication system. To this end, a method for performing a control service which can remotely control a second wireless device by a first wireless device may include the steps of: the first wireless device searching for the second wireless device; when the second wireless device is found, the first wireless device receiving command information supported by the second wireless device from the second wireless device; the first wireless device transmitting, to the second wireless device, command identification information for identifying a command to be processed by the second wireless device; and the first wireless device receiving a feedback on a processing result of the command from the second wireless device.
Abstract:
A method and apparatus for transmitting a signal from a base station to a first user equipment (UE) in a multiple-input multiple-output (MIMO) wireless communication system. Information on a movement speed of a second UE is acquired from the second UE. Channel information is determined based on the information on the movement speed. The channel information is previously measured by the first UE. A transmission and reception scheme is determined based on the determined channel information. At least one of the determined channel information or the determined transmission and reception scheme is transmitted to the second UE.
Abstract:
One embodiment of the present invention relates to a method by which a first device for supporting a WiFi direct service establishes a session, comprising: a step for enabling an application service platform (ASP) layer to receive an Advertise Service method from a service layer; a step for enabling the ASP layer to receive a REQUEST— SESSION message from a second device; a step for enabling the ASP layer to receive a SetSessionReady method from the service layer; and a step for enabling the ASP layer to transmit an ADDED_SESSION message to the second device in response to the REQUEST_SESSION message, wherein at least one of the AdvertiseService method, the REQUEST_SESSION message, and the ADDED_SESSION message includes port information, and the port information included in the AdvertiseService method is the same as the port information included in the ADDED_SESSION message when the first device gives, to the second device, the port information related to the session.
