FIELD: wireless communication.
SUBSTANCE: access point comprises a processor, which during operation generates a flip-flop frame, which includes a general information field and a user information field, common information field includes a flip-flop sub type which identifies trigger flip-flop type, wherein several trigger types enable assignment of resource blocks (RU) for arbitrary uplink OFDMA access (UORA), and the user information field includes an association identification (AID) subfield, wherein the subfield AID with a determined value indicates that the user information field has assigned one or more RUs for the UORA; and a transmitter, which during operation transmits a generated flip-flop frame to a wireless station.
EFFECT: technical result consists in possibility of assigning higher priority to selected types of frames and/or categories of STA during random OFDMA-access to uplink.
