Abstract: One embodiment of the present specification relates to a method for performing low-latency communications. According to one embodiment, an interframe space (IFS) for low-latency data may be suggested. The interframe space for low-latency data may be set to be greater than PIFS and smaller than DIFS. On the basis of the interframe space for low-latency data, a reception STA may perform EDCA and transmit low-latency data to a transmission STA.

Abstract: Proposed are a method and device for receiving a PPDU in a wireless LAN system. Specifically, a reception STA receives a PPDU from a transmission STA through a broadband and decodes the PPDU. The PPDU includes a control field and a data field. If the broadband is a 160/80+80 MHz band that includes a primary 80 MHz channel and a secondary 80 MHz channel, the data field is received via a second multiple RU in which 484-RU and a first multiple RU are aggregated. The first multiple RU is a multiple RU in which first and second 26-RUs, 52-RUs and 106-RUs are aggregated. The second multiple RU is allocated in the primary 80 MHz channel and the secondary 80 MHz channel.

Abstract: Proposed are a method and a device for receiving a PPDU in a wireless LAN system. Specifically, a receiving STA receives a PPDU from a transmitting STA through a first band, and decodes the PPDU. The PPDU comprises a control field and a data field. When the first band is an 80 MHz band comprising first to fourth 20 MHz subchannels, the first 20 MHz subchannel comprises first multiple RUs in which a first 26RU and a first 52RU are aggregated. The first 26RU is an RU located in the middle of the first 20 MHz subchannel. The first 52RU is an RU having a frequency lower than that of the first 26RU, and which is adjacent to the first 26RU.

Abstract: In a wireless local area network (WLAN) system, a transmitting multi-link device (MLD) may defer the transmission of a PPDU on a first link, even if a back-off counter of a non-primary link reaches zero, as long as a back-off counter of a primary link does not reach zero. When the transmission of the PPDU is deferred, the back-off counter may be kept at zero.

Abstract: A transmission station (STA) of a wireless local area network system, according to various embodiments, may configure a plurality of blocks for encoding. The plurality of blocks may each comprise a data block and a CRC block for detecting an error of the data block. The transmission STA encodes each of the plurality of blocks and may transmit the plurality of encoded blocks.

Abstract: In a wireless local area network system, a station (STA) may transmit a low-latency queue activation signal. The STA may additionally receive, from an access point (AP), allocation of a resource for data transmitted using a low-latency queue. The STA may transmit a signal requesting, from the AP, a change of an allocation resource.

Abstract: In a wireless local area network, a reception station (STA) may receive, from a transmission STA, a first signal via a first link and a second signal via a second link. The reception STA may transmit, to the transmission STA via the second link, a response signal associated with whether the first and second signals are to be received. The response signal may include a first field associated with the feature of the response signal including responses with respect to whether a plurality of signals transmitted via a plurality of links are to be received.

Abstract: Proposed are a method and apparatus for receiving PPDU in a wireless LAN system. Specifically, a receiving STA receives a PPDU from a transmitting STA via broadband and decodes the PPDU. The broadband is a 320 MHz or 160+160 MHz bandwidth that is not preamble punctured. The PPDU includes a first field and a second field. The first field includes L-LTF. The PPDU includes a first signal field and a second signal field. The first field includes L-LTF. The first field is generated on the basis of one of a first, second, third or fourth phase rotation value. The first phase rotation value is a phase rotation value that obtains PAPR of the L-LTE optimized for the broadband on the basis of a first combination of RFs used for transmitting the PPDU. The first combination of RFs is a combination of 160 MHz-capable RFs or 320 MHz-capable RFs.
