Abstract:
Disclosed is a method for sharing in advance a multicast address in a wireless communication system. To this end, a method can comprise the steps of: selecting a multicast address; and transmitting a beacon frame comprising the selected multicast address. The beacon frame can comprise a search beacon frame and/or a synchronization beacon frame.
Abstract:
The present document relates to a wireless communication system and, more particularly, to a method for establishing a wireless channel by an AP in a high-density wireless LAN system and to an apparatus therefor. The AP configured for this purpose can establish a primary channel and one or more secondary channels, establish one or more downlink oriented channels into one or more secondary channels, but without the one or more downlink oriented channels overlapping the primary channel of an adjacent basic service set (BSS), and transmit, to a station connected to the AP, the frame including establishment information on the established one or more downlink oriented channels.
Abstract:
A method and an apparatus for receiving a downlink frame in a wireless LAN are disclosed. The method and apparatus for receiving a downlink frame in a wireless LAN may comprises the steps of: an STA receiving from an AP a downlink frame via a downlink dedicated channel; and the STA transmitting to the AP a response frame related to the downlink frame via the downlink dedicated channel. The downlink dedicated channel allows transmission only of a contention-free downlink frame by the AP and a response frame by the STA, and restricts transmission of an independent uplink frame by the STA, wherein the independent uplink frame may be an uplink frame other than a response frame among uplink frames that are transmitted from the STA to the AP.
Abstract:
A method and an apparatus for accessing a channel are disclosed. The method of an STA accessing a channel may comprise the steps of: and STA that is operable in a power-saving mode switching from a sleep state to an active state during a beacon interval; the STA monitoring a channel access parameter frame after being switched to the active state; the STA receiving the channel access parameter frame from an AP, wherein the channel access parameter frame includes EDCA set determining information; and the STA accessing a channel using an EDCA parameter determined on the basis of the EDCA set determining information, wherein the channel access parameter frame can be transmitted at least once between beacon intervals.
Abstract:
Method and device for receiving a data unit are disclosed. A method for receiving a PPDU including a PPDU header and a data field of an STA may comprise the step of: an STA receiving the PPDU header from an AP; the STA determining whether the PPDU transfers a scanning frame on the basis of the PPDU header; and the STA determining whether to decode the data field on the basis of whether to perform a scanning procedure and whether the PPDU transfers the scanning frame.
Abstract:
The present invention relates to a wireless communication system. Disclosed are a method for searching for a device and an apparatus therefor. To this end, the method for searching for a device of a first wireless device comprises: transmitting a probe request frame; and receiving a probe response frame from a second wireless device in response to the probe request frame, wherein the probe response frame may contain information on an access point (AP) to which the second wireless device is currently connected.
Abstract:
The present invention is directed to a wireless communication system. Specifically, the present invention is directed to a method of performing a procedure for link-setup and an apparatus therefore, wherein the method comprises: receiving a probe request frame including time information via a channel, wherein the time information indicates at least one of a minimum scan time for the channel and a maximum scan time for the channel; and performing a procedure for transmitting a probe response frame after receipt of the probe request frame, wherein if a beacon transmission time occurs within a time given based on the time information, transmission of the probe response frame is omitted.
Abstract:
A method and a mobile station operating in a wireless communication system are described. Information on a primary carrier and one or more secondary carriers is received on a multi-carrier from a base station. Information on activation or deactivation of the one or more secondary carriers is received. The mobile station communicates with the base station via the primary carrier and one or more activated secondary carriers. Configuration information for power management is received that informs the mobile station of a first time period during which the mobile station monitors signals from the base station and of a second time period during which the mobile station does not monitor signals from the base station. When a specific indication is received from the base station, the mobile station stops the first time period and enters into the second time period.
Abstract:
Provided are a method for performing wireless communication by a first device, and an apparatus for supporting same. The method may comprise: triggering a resource selection; determining a selection window, based on the resource selection being triggered; selecting a first sidelink (SL) transmission resource within the selection window, based on sensing; obtaining a first Channel Occupancy Time (COT); removing the first SL transmission resource, based on a reselection of the first SL transmission resource; and selecting a second SL transmission resource, based on the first COT.
Abstract:
Provided are a method by which a first apparatus performs wireless communication and an apparatus supporting same. The method comprises the steps of: obtaining a plurality of sidelink (SL) DRX inactivity timers that are mapped to a plurality of SL quality of service (QoS) profiles associated with a destination layer-2 (L2) identifier (ID); receiving, through a physical sidelink control channel (PSCCH), first sidelink control information (SCI) for scheduling a physical sidelink shared channel (PSSCH) and second SCI; receiving, through the PSSCH, the second SCI comprising a destination layer-1 (L1) ID and cast type information; selecting one SL DRX inactivity timer from among the plurality of SL DRX inactivity timers associated with the destination L1 ID, on the basis of failure to decode a medium access control (MAC) protocol data unit (PDU); and starting the one SL DRX inactivity timer, wherein the one SL DRX inactivity timer may be an SL DRX inactivity timer that has the longest duration among the plurality of SL DRX inactivity timers.
