Abstract
Access to a wireless medium is made more flexible by combining the distributed access and central controlled access. A wireless device may be allowed to perform both orthogonal frequency-division multiple access (OFDMA) and enhanced distributed channel access (EDCA) channel access mechanisms at same time and start the channel access via a mechanism that allows a faster access to the channel. Depending on channel acquisition, the wireless device can use a multi-user format or a single-user format to transmit uplink anPLCP protocol data unit (PPDU).
