Abstract: 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.

Abstract: Provided are a method and a device for sending traffic indication information. In the method, an AP sends a radio frame to multiple STAs associated with the AP, wherein the radio frame carries an indication field, and the indication field is used to indicate whether the radio frame carries traffic indication virtual bitmap information. According to the technical solution provided, in the case where the AP has no unicast cache data for any station, multiple STAs associated with the AP can know whether the AP has their respective unicast cache data to be sent.

Abstract: 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.

Abstract: The present document provides a method for avoiding downlink data collision, an Access Point (AP) and a Station (STA). The method for avoiding downlink data collision includes: an AP receiving a radio frame for inquiring whether the AP has a Bufferable Unit (BU) of an STA transmitted by the STA; and after determining that there is a BU of the STA and the BU is larger than a predetermined threshold, the AP exchanging radio frames with the STA to reserve a channel, and transmitting the BU to the STA after succeeding in reserving the channel. The method can guarantee the fairness among various STAs and the reasonable utilization of channel resources, thus avoiding the collision; furthermore, the channel reservation frame transmitted by the AP can reserve a longer period of time, i.e. a plurality of BUs can be transmitted to the STA at a time, thus saving the link overhead.
