Abstract: The present disclosure relates to the prioritization of devices taking part in a multi-user random access wireless communication. Based on some known conditions, devices that comply with the conditions are given preferential treatment during the random access period. The preferential treatment may refer to the eligible devices being allowed to access more resource units during the random access, or it may also mean faster access to the medium during the random access. By taking advantage of the methods described in the present disclosure, it is possible to assign higher priority to selected frame types and/or device categories in a multi-user random access wireless communication system.

Abstract: An transmission apparatus of the present disclosure comprises a transmission signal generator which, in operation, generates a transmission signal that includes a legacy preamble, a non-legacy preamble and a data field, wherein the non-legacy preamble comprises a first signal field and a second signal field, the second signal field comprising a first channel field and a second channel field, each of the first channel field and the second channel field comprising a common field that carries resource unit (RU) allocation information and a user-specific field that carries per-user allocation information for one or more terminal stations, and wherein a part of the user-specific field of one of the first channel field and the second channel field whichever is longer than the other channel field in length before appending padding bits is relocated to the other channel field; and a transmitter which, in operation, transmits the generated transmission signal.
