Abstract: The present invention relates to a method of transmitting and receiving a signal in a wireless communication system. In particular, in a time division multi-cell cooperative communication system, a base station may receive a reference signal, estimate a channel of each user terminal based on the reference signal, and determine a transmission and reception filter based on estimated channel information. The base station and a cooperative base station that cooperates with the base station may mutually exchange the reference signal and average signal power information on a terminal and determine the transmission and reception filter based on exchanged information.

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.

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: A method and a device for transmitting an A-PPDU in a wireless LAN system are proposed. Specifically, a transmission STA generates an A-PPDU and transmits the A-PPDU to a reception STA. A first PPDU and a second PPDU are aggregated into the A-PPDU. The first PPDU includes an L-Header field, a first EDMG-Header field, and a first data field. The second PPDU includes a second EDMG-Header field and a second data field. Zero padding is inserted in the first data field on the basis of the minimum number of symbol blocks of the first PPDU.
