Abstract:
The present invention relates to a bundling scheduling method in a wireless access system and an apparatus therefor. Specifically, the bundling scheduling method in the wireless access system comprises the steps of: transmitting the bundled downlink control information including a plurality of downlink control information through one physical downlink control channel (PDCCH) to a terminal; transmitting the downlink data, to the terminal, through a plurality of physical downlink shared channels (PDSCH) scheduled by the bundled downlink control information; and receiving acknowledgement/negative-acknowledgement (ACK/NACK) information for the plurality of PDSCHs from the terminal.
Abstract:
Proposed are a method and device for receiving an EHT PPDU on the basis of a tone plan in a wireless LAN system. Specifically, a reception STA receives the EHT PPDU from a transmission STA through a 320 MHz band. The reception STA decodes the EHT PPDU. The EHT PPDU includes a control field and a data field. The control field includes information about a pilot tone. The information about the pilot tone includes allocation information indicating that a first pilot tone for the 320 MHz band is configured by repeating a second pilot tone for an 80 MHz band defined in an 802.11ax wireless LAN system. The first pilot tone is received in a data field on the basis of the allocation information.

The first field may include information about a configuration of a plurality of resource units (RUs). The second field may include a plurality of user fields for allocating the plurality of RUs to a plurality of users. The reception STA may identify a multiple RU (M-RU) allocated to itself and decode the received PPDU.
Abstract:
In a wireless local area network (LAN) system, a station (STA) can generate a plurality of long training field (LTF) symbols used for a plurality of streams including first to fourth streams. The first to fourth streams use different LTF sequences, and the LTF sequences used by the first to fourth streams may be multiplied by the same element of a P matrix. The STA may include a step for transmitting a PHY protocol data unit (PPDU) including the plurality of LTF symbols.
Abstract:
An example according to the present specification relates to a technique for configuring a preamble in a wireless LAN (WLAN) system. A transmitting STA may generate and transmit an EHT PPDU. The EHT PPDU may comprise an L-SIG field, an RL-SIG field, a first control field, and a second control field. A result of “modulo 3 operation” for a length field value of the L-SIG field may be set to “0.” The RL-SIG field may be configured to be the same as the L-SIG field. The first control field may comprise 3-bit information on the version of a PPDU, 6-bit information on a BSS color, and 7-bit information on TXOP.
Abstract:
A transmission station (STA) of a wireless local area network system according to various embodiments can determine a first code rate and encode first data on the basis of a second code rate which is lower than the first code rate. The transmission STA can again generate second data on the basis of the first code rate and the encoded first data and transmit same.

A method and apparatus for receiving a PPDU in a wireless LAN system are proposed. Specifically, a receiving STA receives a PPDU from a transmitting STA through a first band, and decodes the PPDU. The PPDU comprises first to third fields. The first field comprises information on the bandwidth of the first band. The second field comprises information on whether preamble puncturing is performed in the first band. The third field comprises information about a pattern of preamble puncturing.
Abstract:
The present specification proposes a method for resuming a PHY-level HARQ operation in a wireless local area network (WLAN) system. The method may include transmitting a resume signal including information related to resumption of hybrid automatic repeat request (HARQ) retransmission. The method may include transmitting a physical protocol data unit (PPDU) after transmitting the resume signal. The PPDU and the resume signal may be transmitted in different transmission opportunities (TXOPs).
Abstract:
Proposed are a method and an apparatus for receiving an EHT PPDU in a wireless LAN system. Specifically, a reception STA receives an EHT PPDU including an STF signal from a transmission STA through a 320 MHz band or a 160+160 MHz band. The reception STA decodes the EHT PPDU. The STF signal is generated on the basis of an EHT STF sequence for the 320 MHz band or the 160+160 MHz band. The EHT STF sequence for the 320 MHz band is a first sequence in which a preconfigured M sequence is repeated, and is defined as {M −1 −M −1 M −1 M 0 −M 1 −M 1 −M 1 M 0 −M 1 M 1 −M 1 −M 0 M −1 M −1 M −1 −M}*(1+j)/sqrt(2).
