Abstract: 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.

Abstract: Disclosed is a method for configuring radio transmission and reception parameters. The method includes: configuring, by a station, a transmission module by using a first parameter set and transmitting a first radio frame, where the first radio frame has a second parameter set; and configuring, by the station, a reception module by using the second parameter set and receiving a second radio frame triggered by the first radio frame. Also disclosed are an apparatus and system for configuring radio transmission and reception parameters.

Abstract: A method for processing a network allocation vector (NAV) includes: terminating the receiving of a first radio frame when it is determined that a target receiving station of the first radio frame being received is not a first station; and updating an NAV of the first station or maintaining the NAV of the first station unchanged according to a remaining duration of the first radio frame and a first transmission opportunity duration carried in the first radio frame, where the remaining duration of the first radio frame is the transmission time used for transmitting the remaining part of the first radio frame after the receiving of the first radio frame is terminated. The technical solution solves the problem in the related art of collisions with hidden stations caused by an inaccurate NAV update in the existing art, thereby ensuring the accuracy of an NAV update and the fairness of transmission and channel contention, and reducing collisions among hidden stations.

Abstract: A radio frame processing method applied to a first station. The method includes: after detecting a first radio frame, determining whether the first station is in an associated state; if the first station is in the associated state, determining a home situation of the first radio frame according to first attribute information carried in the first radio frame and second attribute information corresponding to a first access point station with which the first station is associated, and performing carrier detection according to a first preset rule based on the home situation of the first radio frame; and if the first station is in an unassociated state, performing the carrier detection according to a second preset rule.

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: Access to a wireless medium is controlled based on contention arbitration. A certain number of wireless devices are allowed by an access point to contend for a transmission opportunity. A trigger frame is used to communicate access opportunities to multiple devices. A beacon transmission may additionally be used for communication of access opportunities.
