摘要： A method of setup a protection mechanism for scheduled transmissions to multiple stations is introduced. Through transmitting a control frame addressing to multiple stations for immediate simultaneous responses, the transmitter would know the stations that are ready for receiving the scheduled data frames and schedule the packet for those stations. Combining the transmission of the control frame with the power saving mechanism would allow triggering a group of power saving stations to wake up at same for receiving the control frame and scheduled user data frames. A new mechanism of simultaneous group responses to the control frame with orthogonal identifier information for individual station is provided to uniquely identify the responding stations.

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. A wireless station receives the transmitted beacon frames and uses the information in the beacon frames to associate with a wireless network.

摘要： Methods, systems, and devices relate to digital wireless communication, and more specifically, to techniques relate to dynamic change MAC address of the station for subsequent transmissions. In one exemplary aspect, a method of dynamic change MAC address includes specifying a MAC address change mode and a new MAC address to be used by the station. In another exemplary aspect, a method of dual MAC address change mode in the dynamic change MAC address mechanism includes separating the unchanged MAC address of the station from the changeable MAC address of the station, and keep the mapping between them. In another exemplary aspect, a method includes transmitting a MAC address change request message from the station (or the access point) to initiate the MAC address change procedure. In another exemplary aspect, a method includes receiving a MAC address change response message from the access point (or the station).

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).

摘要： Method, systems and devices for location information determination based on timing measurements are described. One example method includes transmitting, by a communication apparatus, a timing request to a plurality of network devices, where the timing request comprises a respective expected response time for each of the plurality of network devices, receiving, at a plurality of times, a plurality of timing measurements from each of the plurality of network devices, wherein each of the plurality of times is based on the corresponding expected response time, and the plurality of timing measurements comprises a respective time of arrival (ToA) timestamp and a respective time of departure (ToD) timestamp, and determining a location information of the communication apparatus based on an estimate of a round trip delay that is computed using a difference of the respective ToA and ToD timestamps from the plurality of timing measurements.

摘要： In a wireless network, full duplex communication is established using a half-duplex mechanism. During a full duplex communication opportunity, a first quantum of data is transmitted from a first station to a second station and a second quantum of data is received by the first station from the second station. The full duplex transmission opportunity is implicitly or explicitly established and ended using a transmission mechanism understood by half duplex wireless stations.

摘要： Multiple wireless devices in a network perform full duplex communication in which the transmission path and receiving path are spatially separated to allow simultaneous transmission and receiving. The wireless devices can either be controlled using a centralized, or point, coordination function or a distributed coordination function. A full-duplex wireless device senses the medium during transmission by itself and selectively continues the transmission when a signal is sensed on the medium. A full-duplex wireless device measures signal being transmitted by its transmitter and estimates parameters that can be used to cancel the contribution of the locally transmitted signal to the locally received signal concurrently being received during the transmission. The transmit antenna and the receive antenna of a full-duplex wireless device can be configured to be spatially isolated from each other to minimize interference between the antenna functions.
