Abstract: A control information transmission method includes that: a first station sends a wireless signal including control information, where the control information is used for instructing a specified second station in a sleep state to perform one or more of following operations: state update, sleep mode transition, leaving the sleep state, and an operation after leaving the sleep state. A secondary module of the second station receives and decodes a wake-up signal to obtain control information and identity identifier information, and sends the control information and the identity identifier information to a control module; and the control module of the second station determines, according to the identity identifier information, whether the second station is a target second station of the wake-up signal, and parses and completes an operation indicated in the control information.

Abstract: A method for transmitting data and a station are described. The method includes: when there is data to be sent in a station, determining whether there is a station using a channel in a BSS to which the station belongs and an OBSS using virtual channel detection; when determining that there is no station using the channel in the BSS to which the station belongs and there is a station using the channel in the OBSS, starting or resuming a back off procedure for OBSS spatial reuse transmission of the station; and monitoring the channel in the back off procedure for the OBSS spatial reuse transmission according to a fixed first channel detection threshold and a dynamically adjusted second channel detection threshold, transmitting data when the back off procedure for the OBSS spatial reuse transmission ends.

Abstract: The embodiments of the present document provide a method for processing dynamic channel detection, a station and an access point device. The method includes a station transmitting a dynamic channel detection request to an access point and the station deciding whether to use dynamic channel detection according to response information from the access point. The embodiments of the present document enable the station and the access point to negotiate whether to use a dynamic channel detection threshold. This is advantageous in finding the best balance point between improvement of channel utilization and avoidance of collision.

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: 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.
