摘要： A transmitting wireless device provides channel spatial reuse information to a receiving wireless device for the receiving wireless device to make a determination of how to contend the medium for spatial reuse transmission, when to transmit and what transmissions parameters to use for the transmission in the spatial reuse. A timer is designated to track the remaining time for inter-ESS and/or intra-ESS spatial reuse. The spatial reuse information may include fields indicative of color code identifying BSS, transmission power used, signal to noise ratio headroom available and so on. With the spatial reuse information, the wireless device can calculate the target transmit power for initiating spatial reuse transmission without interrupting the on-going transmission, perform EDCA in spatial reuse condition to assess the channel status for contending the medium over the on-going transmission(s), tracking the spatial reuse duration and initiate a new spatial reuse transmission over the on-going transmission without interruption.

摘要： A transmitting wireless device dynamically and periodically transmits beacon frames including either full set of information or a partial information about the BSS. The wireless device schedules the target beacon transmission time and target dynamic beacon transmission time to have different starting time and different interval for each BSS. A Nack based mechanism for detecting and report missing dynamic beacon frames is used to provide the wireless access point with a feedback information of dynamic beacon transmission for improving the transmission efficiency and reliability.

摘要： 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).
