1. An integrated circuitry for a station apparatus, comprising:
at least one input, which, in operation, receives an input; and
control circuitry, which is coupled to the at least one input and which, in operation, controls:
receiving, from an access point, a trigger frame including a common information field and a user information field, the common information field including a trigger type subfield that identifies a trigger type of the trigger frame and the user information field including an association identification (AID) subfield;
responsive to the trigger type of the received trigger frame allowing allocation of resource units (RUs) for uplink OFDMA random access (UORA), and responsive to the AID subfield indicating that the user information field allocates RUs for UORA, contending for access to the RUs for UORA with one or more other station apparatuses; and
transmitting a frame using at least one of the RUs for UORA.
