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.

Abstract: Provided are a data sending feedback method and apparatus, and a data sending method and apparatus. According to data sending feedback method, when reception of a radio frame fails, a receiving station detects whether transmission of the radio frame over a specified sub-channel in a working channel ends within predetermined time; after the receiving station detects that the transmission of the radio frame over the specified sub-channel in the working channel ends within the predetermined time, the receiving station sends a feedback frame to a sending station of the radio frame.

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: Provided are a method and system for a wireless STA to access a channel. The method includes that the wireless STA acquires a transmission ending moment of a wireless frame when selecting to refuse or drop the wireless frame and not updating a locally stored Network Allocation Vector (NAV); and the wireless STA accesses the channel when the transmission of the wireless frame is ended and a preset condition is met. According to the disclosure, a collision problem may happen to the wireless STA, and the wireless STA can access the channel only when the preset condition is determined to be met after the transmission of the wireless frame is ended, so that the problem of transmission collision with a hidden STA during the wireless frame transmission of the wireless STA is solved.

Abstract: A transmitting wireless device provides channel access information to a receiving wireless device for the receiving wireless device to make a determination of when to transmit and what transmissions parameters to use for the transmission. The channel access information may be used differently by wireless devices operating in a basic service set and an overlapping basic service set. Channel access information may include fields indicative of transmission power used, signal to noise ratio headroom available, and so on. Channel access information may be generated and transmitted at the PHY layer of an implementation, thus providing a fast delivery to the receiving wireless device.

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 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.

Abstract: Access to a wireless medium is controlled based on contention arbitration. A certain number of wireless devices are allowed to contend for a transmission opportunity. Requests from these wireless devices are processed based on codes contained in the requests. Winning wireless devices are given access to the wireless medium by transmitting a contention arbitration message. In some implementation, codes in the request are selected from an orthogonal or pseudo orthogonal code set.
