摘要： 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.

摘要： A transmission method comprises: generating a transmission signal including OFDM symbols, wherein the last OFDM symbol of the OFDM symbols can be partitioned into four segments, and wherein the generating includes: computing an initial padding factor value associated with one of the four segments and computing an initial number of OFDM symbols; determining a user with a longest packet duration among plural users; determining a common padding factor value being the initial padding factor value and a common number of OFDM symbols being the initial number of OFDM symbols of the determined user with the longest packet duration; adding pre-FEC padding bits toward one of four possible boundaries of the last OFDM symbol, the one of four possible boundaries being represented by the determined common padding factor value; and adding post-FEC padding bits in remaining segment(s) of the last OFDM symbol; and transmitting the generated transmission signal.

摘要： A transmission apparatus of the present disclosure comprises a packet generator which, in operation, generates a packet and a transmitter which, in operation, transmits the generated packet. The packet includes a legacy short training field, a legacy long training field, a legacy signal field (L-SIG), a repeated legacy signal field (RL-SIG), a first non-legacy signal field, a second non-legacy signal field, a non-legacy short training field, a non-legacy long training field and a data field, wherein the second non-legacy signal field is optionally present. The packet generator generates the packet by configuring the RL-SIG in different ways according to a presence or absence of the second non-legacy signal field in the packet.
