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: A transmission apparatus comprises circuitry that generates a physical protocol data unit (PPDU) that contains a legacy signal field and a first signal field wherein both of the legacy signal field and the first signal field comprise an Orthogonal Frequency Division Multiplexing (OFDM) symbol, and the first signal field is derived from the legacy signal field, and a transmitter, which, in operation, transmits the PPDU. A format of the PPDU is indicated based on whether a part of bits of the first signal field is inverted or not. The format of the PPDU is a first format or a second format, and data subcarriers of the first signal field in the second format have inverted values of corresponding values in the legacy signal field, and pilots of the first signal field in the second format are not inverted and have same values of corresponding values in the legacy signal field.

Abstract: A communication method for transmitting a block acknowledgment (BlockAck) frame is presented. The communication method includes receiving a plurality of frames from a transmitting device, wherein the payload of a frame may consist of either fragmented or unfragmented packet, recording the receive status of the frames, generating a BlockAck frame that contains at least one Bitmap field used to indicate the receive status of the frames, the number of bits allocated in the Bitmap field for a packet being variable and transmitting the BlockAck frame.
