20150327313 | METHOD AND DEVICE FOR SESSION INITIALIZATION IN WIRELESS COMMUNICATION SYSTEM - One embodiment of the present invention is a method for session initialization in which a first device for supporting a Wi-Fi direct service initializes a send session with a second device. The method for session initialization comprises the steps of: establishing an application service platform (ASP) session; and initializing the send session using a uniform resource locator (URL) related to a device description, wherein the URL related to the device description is acquired prior to the completion of the establishment of the ASP session. | 11-12-2015 |
20150334638 | SERVICE DISCOVERY METHOD AND DEVICE IN WIRELESS LAN SYSTEM - The present invention relates to a wireless communication system, and more particularly, to a service discovery method and device in a wireless LAN system. A service discovery method in a wireless LAN system according to one embodiment of the present invention can comprise: transmitting, by a request device, a service discovery request frame to a response device; and receiving, by the request device, a service discovery response frame, which comprises service information of the response device and service information of each of one or more other devices, from the response device. The one or more other devices can comprise a device which does not belong to the same group as the response device. | 11-19-2015 |
20150334654 | CHANNEL ACCESS METHOD AND APPARATUS IN WIRELESS LAN SYSTEM - The present invention relates to a method for converting, by a station (STA), a non-traffic indication map (TIM) mode into a TIM mode and performing channel-accessing. According to the present invention, a station that does not receive a TIM or DTIM is to be switched so as to operate between a wakeup mode and a sleep mode for power saving. In order to set an efficient wakeup time, the STA may listen to beacon frame information from an AP and access a channel through information included in the beacon frame information. | 11-19-2015 |
20150341849 | METHOD FOR SEARCHING FOR SERVICE OR ADVERTISING IN DIRECT COMMUNICATION SYSTEM AND DEVICE THEREFOR - The present invention relates to a wireless communication system, and a method for executing a service search and an advertisement. To this end, the method by which a first wireless device performs a service search comprises the steps of: transmitting a probe request frame which includes a hash value; receiving, from a second wireless device, a probe response frame which includes first service information corresponding to the hash value; transmitting a service search request frame which includes a search word to the second wireless device; and receiving, from the second wireless device, a service search response frame which includes second service information corresponding to the search word, wherein if a preset symbol is attached to the search word, the second service information can include at least one service name having the search word as a prefix. | 11-26-2015 |
20150373758 | METHOD FOR TRANSMITTING/RECEIVING INFORMATION RELATED TO ASSOCIATION IDENTIFIER IN WIRELESS COMMUNICATION SYSTEM AND DEVICE THEREFOR - One embodiment of the present invention relates to a method for transmitting/receiving information related to an association identification (AID) in a wireless communication system, the transmitting/receiving method comprising: a step in which a second STA having a direct link to a first STA receives an announcement frame related to an updated AID from the first STA; and a step in which the second STA transmits an ACK frame in response to the announcement frame, wherein the announcement frame comprises one or more AID-MAC address pairs and the second STA updates the AID of an STA corresponding to the one or more AID-MAC address pairs. | 12-24-2015 |
20160044662 | METHOD AND APPARATUS FOR RECEIVING SIGNAL BY STATION IN WIRELESS LAN SYSTEM - An embodiment of the present invention provides a method for receiving a signal from an access point (AP) by a station (STA) in a wireless communication system, the method comprising the steps of: receiving a raw parameter set (RPS) element including a restricted access window (RAW) allocation field; and identifying, in the RAW allocation field, first information indicating whether the RAW allocation field relates to a periodic RAW and second information indicating whether the RAW allocation field relates to AP power management (PM), wherein the STA can acquire only information relating to a time interval of the RAW in subfields other than a subfield including the first information and the second information when the RAW relates to the AP PM. | 02-11-2016 |
20160057779 | METHOD AND APPARATUS FOR ACCESS IN WIRELESS LAN SYSTEM - An embodiment of the present invention provides a method for accessing to a medium by a station (STA) in a wireless LAN system, the method comprising the steps of: receiving a predetermined frame including a time stamp; identifying a restricted access window (RAW) assignment field included in the predetermined frame; and performing access in a slot determined on the basis of a subfield of the RAW assignment field when the STA belongs to a RAW related to the RAW allocation field, wherein whether the STA belongs to the RAW is determined by whether an association identifier (AID) of the STA is included in a AID range and the RAW assignment field includes a subfield indicating whether the AID range is determined by a TIM bitmap. | 02-25-2016 |
20160057780 | METHOD AND DEVICE FOR PERFORMING ACCESS IN WIRELESS LAN SYSTEM - One embodiment of the present invention, in a method for enabling a station (STA) to perform an access to a medium in a wireless communication system, is a method for performing an access, comprising the steps of: receiving a frame including an RPS element; checking a restricted access window (RAW) assignment field within the RPS element; and performing an access on the basis of a RAW start time when the STA corresponds to a RAW group related to the RAW assignment field, wherein the RAW start time is obtained on the basis of a start time indication sub field, and the start time indication sub field indicates whether the RAW start time sub field indicating the RAW start time is included in the RAW assignment field. | 02-25-2016 |
