Abstract:
A method of transmitting a White Space Map information in a wireless local area network system (WLAN) is disclosed. A method of transmitting a white space map information from a first station to a second station in a regulatory domain where a licensed device and an unlicensed device are permitted to operate together in a wireless local area network (WLAN) comprises acquiring a first list of available channels at each location of a plurality of locations from a regulatory database; determining a second list of available channels at a white space zone (WSZ) using the first list of available channels at each location of a plurality of locations; and transmitting, to the second station, one of a beacon frame, a probe response frame and a white space map announcement frame comprising a white space map (WSM) element, the WSM element including information of the WSZ and the second list of available channels, wherein the WSZ is a geographical area in which commonavailable channels are set.
Abstract:
A method and apparatus for performing a relay operation in a wireless LAN (WLAN) system are disclosed. A method for performing a relay operation by an entity of a wireless LAN (WLAN) system includes: transmitting a frame including information indicating whether the entity is a relay access point (AP) or a root AP to at least one station (STA), wherein, if the entity is the relay AP, the frame further includes a Medium Access Control (MAC) address of the root AP associated with the entity.
Abstract:
The present invention relates to a wireless communication system, and more specifically, provides a method and a device for controlling channel access in a wireless LAN system. A method for controlling channel access by a station (STA) in a wireless communication system according to one embodiment of the present invention comprises the steps of: transmitting a first frame, to an access point (AP), for starting a transmission opportunity (TXOP); and receiving a second frame if the second frame responding to the first frame is transmitted from the AP, wherein the second frame can be transmitted from the AP on the basis of whether a duration of the TXOP overlaps a predetermined time set by the AP.
Abstract:
A method and apparatus for transmitting and receiving a frame including a partial association ID (PAID) in a wireless LAN (WLAN) system are disclosed. A method for transmitting a frame from a station (STA) to an access point (AP) in a wireless communication system includes: calculating a partial association ID (Partial AID) on the basis of a basic service set ID (BSSID) of the AP; and transmitting the frame including a partial AID field set to a specific value corresponding to the calculation result of the partial AID to the AP. The partial AID is calculated by applying a modulo operation to a specific value obtained by converting values ranging from a 40th bit position to a 48th bit position from among 48 bit positions of the BSSID of the AP into a decimal number.
Abstract:
Disclosed is a method for a station (STA) for accessing a channel in a wireless communication system. The method for a STA for accessing a channel in a wireless communication system comprises the steps of: receiving a beacon frame comprising a traffic indicator map (TIM); and transmitting a power save (PS)-Poll frame if buffered traffic is indicated by TIM to the STA, wherein the PS-Poll frame is transmitted during a PS-Poll dedicated restricted access window (RAW) by and/or during an additional RAW, the PS-Poll dedicated RAW being allocated to transmit the PS-Poll frame, and the additional RAW being additionally allocated subsequent to the PS-Poll-dedicated RAW.
Abstract:
The present invention relates to a method for transmitting and receiving a traffic indication map in a wireless communication system, and to an apparatus for same. More particularly, the method includes a step of transmitting a traffic indication map (TIM) to a station (STA) through a beacon frame, wherein the TIM can include a bitmap field configured of one or more sub-block bitmaps for indicating whether buffered downlink data exists for an STA which is grouped to one or more sub-blocks, and a block control field indicating an encoding scheme of the bitmap field.
Abstract:
One embodiment of the present invention relates to a method for transmitting a signal of a station (STA) operable in a power saving mode in a wireless communication system, and the method for transmitting a signal comprises a step of transmitting a PS-Poll frame and/or a trigger frame according to a first time period, wherein an integrated scaling factor is applied to the first time period, and the integrated scaling factor is also commonly applied to a second time period in which the STA can omit frame transmission by maintaining an association state with an access point (AP).
Abstract:
Provided is a method for transmitting a data unit performed by a transmitter in a wireless LAN system. The method comprises: generating a data unit, wherein the data unit includes a data field which contains data to be transmitted by a transmitter; generating at least one data symbol for the data field; and transmitting the at least one data symbol, wherein two pilot tones are inserted into each data symbol, and pilot values and scrambling values are applied to the pilot tones.
Abstract:
A wireless communication system is disclosed. Specifically, a channelization method in a whitespace band and an apparatus for the same are disclosed. A method for providing whitespace operation information includes transmitting, by a first station (STA) to a second STA, a frame including a TV whitespace high throughput (TVHT) operation information field. The TVHT operation information field includes primary channel number, channel width, channel center frequency segment 0 and channel center frequency segment 1 subfields. A channel center frequency of frequency segment 0 or frequency segment 1 is determined based on a channel start frequency. The channel start frequency is determined as a function of a TV channel index corresponding to the frequency segment 0 or a TV channel index corresponding to the frequency segment 1.
Abstract:
Disclosed is a method and apparatus for transmitting data in a non-licensed band. The method of transmitting downlink data in the non-licensed band may comprise the steps of: generating, by a base station, downlink data and transmitting the downlink data to a terminal through a downlink subframe. The downlink data may comprise wireless LAN preamble, PDCCH data, and PDSCH data. The wireless LAN preamble may comprise information on time resources for communication between the base station and the terminal, and the PDCCH data may comprise control data for the terminal. Also, the PDSCH data may comprise traffic data for the terminal.
