1. A station, comprising:
an antenna, which, in operation, receives a trigger frame including a common information field and a plurality of user information fields, the common information field including a trigger type subfield that identifies a trigger type of the trigger frame, wherein several trigger types allow allocation of resource units (RUs) for uplink OFDMA random access (UORA), and one user information field of the plurality of user information fields includes an association identification (AID) subfield, wherein the AID subfield with a defined value indicates that the one user information field allocates one or more RUs for UORA; and
circuitry, which, in operation, decodes the received trigger frame.
