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.

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: A wireless local area network comprises an access point and at least one wireless device. The access point indicates in a downlink transmission whether access to the network is based on active scan or polling. The indication is changeable responsive to whether a beacon transmission time is approaching, whether a new scan is to be forced or whether network traffic is about to reach an overload condition.

Abstract: Methods, systems, and devices related to related to digital wireless communication, and more specifically, to techniques related to the power saving mechanism for multi-link operation. In one exemplary aspect, a method for wireless communication includes transmitting a link wakeup indication message to a wireless device over a first link of multiple links between the network node and the wireless device. The link wakeup indication message may indicate a request to transition at least one link of the multiple links between an active state and a power saving state. The method may also include, responsive to transmitting the link wakeup indication message, obtaining, by the network node, a link wakeup notification message from the wireless device indicating that at least one link of the multiple links has transitioned between the active state and the power saving state.

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.
