    Abstract: A wireless communication system using pilot subcarrier allocation and a method of allocating the pilot subcarriers for use in downlink and uplink communication in a multiple-input multiple-output (MIMO) antenna system using orthogonal frequency division multiplexing (OFDM) modulation are disclosed. The method includes providing a frame structure comprising OFDM symbols in time domain and subcarriers in frequency domain and alternately allocating first pilot subcarriers for a first antenna and second pilot subcarriers for a second antenna in the time and frequency domains, wherein each of the alternating first pilot subcarriers and the second pilot subcarriers is separated by a multiple of 9 subcarriers in the frequency domain and further allocated in two contiguous OFDM symbols.

    Abstract: Disclosed are a method and an apparatus for accessing a channel in a wireless LAN system. A method performed by a station (STA) in a wireless LAN system according to an embodiment of the present disclosure may comprise the steps of: receiving information related to a restricted-target wake time (R-TWT) service period (SP) from an access point (AP); and setting at least one R-TWT traffic identifier (TID) for the R-TWT SP. Here, whether to perform a back-off operation for an access category (AC) in the R-TWT SP may be determined on the basis of a mapping relationship between the at least one R-TWT TID and the AC.

    Abstract: In a wireless local area network system, a station (STA) can transmit a first physical protocol data unit (PPDU) including a link adaptation control field. The link adaptation control field can include a bit indicating whether the link adaptation control field includes information related to low-latency traffic. The low-latency traffic can require a latency of less than or equal to a threshold value. The STA can be allocated resources for the low-latency traffic. The STA can transmit a second PPDU including the low-latency traffic through the resources.

    Abstract: Proposed are a method and apparatus for performing sensing in a wireless LAN system. In detail, a first STA broadcasts a sensing request frame. The first STA receives a first sensing response frame form a second STA and receives a second sensing response frame from a third STA. The sensing request frame includes STA identifier information and RU allocation information. The STA identifier information includes identifiers of the second and third STAs. The RU allocation information includes information about a first RU allocated to the second STA and information about a second RU allocated to the third STA. The first sensing response frame is received through the first RU. The second sensing response frame is received through the second RU.
