METHODS AND APPARATUS FOR TRANSMITTING AND RECEIVING A RADIO FRAME Russian patent published in 2020 - IPC H04L1/00 H04B5/00 

FIELD: radio engineering and communications.

SUBSTANCE: invention relates to communication technologies. Method of transmitting a radio frame comprises steps of generating, by a transmission side, generating a zero data packet (NDPA) message, wherein the NDPA complies with 802.11ax standard and comprises one or more station information fields, the length of each station information field is 4 bytes; first two bytes of 4 bytes include an association identifier (AID) field, the next two bytes of 4 bytes do not include any AID; the most significant bit (MSB) of first 12 bits of the next two bytes is set to 1, wherein the MSB of first 12 bits of the next two bytes is 28th bit (B27) of each information field of the station; and transmitting NDPA.

EFFECT: high-efficiency transmission due to use of frame structure, which can fully use OFDMA characteristic.
