Abstract: This disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for high efficiency (HE) beacons. HE supported access points (APs) and stations (STAs) may operate on resource deployments used for Wi-Fi technology and without support for legacy devices, also referred to as a greenfield deployment. An AP may identify updated capability information and transmit a HE physical layer convergence protocol (PLCP) protocol data unit (PPDU) including a beacon frame. A STA may receive, from the AP, the HE or EHT PPDU and identify an indication of change to a content or format of the beacon frame relative to a reference beacon frame. Based on the identified indication, the STA may then determine an updated content or format for the beacon frame and process the beacon frame or skip processing for one or more portions of the beacon frame.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless device that uses a first radio access technology (RAT) may identify a transmission timing scheme for a shared radio frequency spectrum band, the transmission timing scheme comprising a first set of time intervals allocated for transmissions using a first RAT and a second set of time intervals allocated for transmissions using a second RAT. The wireless device may transmit, during a time interval of the first set of time intervals, a channel reservation signal indicating an end time of the time interval and indicating that the wireless device uses the first RAT. The wireless device may transmit, based at least in part on the transmitted channel reservation signal, over the shared radio frequency spectrum band during at least a portion of the time interval before the end time of the time interval.

Abstract: This disclosure provides methods, devices and systems for sharing resources of a wireless medium. Various implementations relate generally to coordinated transmit power control for sharing time and frequency resources of a wireless medium. Particular implementations relate more specifically to coordinated access point spatial-reuse-multiple-access techniques for sharing the time and frequency resources of a transmission opportunity. According to such techniques, an access point that wins contention and gains access to the wireless medium for the duration of a transmission opportunity may limit the transmit powers of the access points selected to share the time and frequency resources such that interference from the selected access points does not prevent stations associated with the winning access point from successfully decoding packets transmitted by it.

Abstract: This disclosure provides methods, devices and systems for providing energy detection based resolution in radio access technologies. In one aspect, a wireless communication device may include a first energy detection threshold (EDT) to identify a transmission opportunity in an unlicensed frequency band. The wireless communication device may detect a second wireless communication device having a second EDT to identify the transmission opportunity, the second EDT being greater than the first EDT. The wireless communication device may, based on detection of the second wireless communication device having the second EDT, modify a transmission configuration of the first wireless communication device.

Abstract: Technology-specific listen before talk (LBT) parameter adjustments are disclosed for common energy detection (ED) thresholds. Some of the technologies sharing access to the same shared communication spectrum include additional access deferral procedures. Such technologies may be configured with additional compensating features to increase the likelihood of fairness in spectrum access across all technologies sharing a common ED threshold. Such additional compensating features may include a reduced contention window size relative to the technologies that do not include such additional access deferral procedures, increased maximum channel occupancy times (COTs) for longer transmissions, and the like. Each such additional compensating feature may be available under different circumstances, such as always available or available in response to the node activating one of the additional access deferral procedures. Additionally, such additional compensating features may, once initiated, be active and available for a predetermined period of time.

Abstract: A relaxed threshold for synchronous access in unlicensed spectrum is disclosed. According to the aspects described herein, nodes accessing a shared communication spectrum using a local synchronous access mode may attempt access via a listen before talk (LBT) procedure using a local synchronous energy detection (ED) threshold. The local synchronous ED threshold is relaxed relative to a standard ED threshold otherwise used for access to the shared communication spectrum. The relaxed nature of the local synchronous ED threshold allows local synchronous access nodes a higher probability to gain access to the shared communication channel. To prevent interference with global synchronous access nodes, the global synchronous access nodes are also able to use the relaxed, local synchronous ED threshold as long as it ends the resulting channel occupancy time (COT) at the next local synchronization boundary.

Abstract: Indication of globally synchronous communications mode is disclosed. A first node may detect an indication signal transmitted by a second node at a synchronization boundary of a shared communication channel. The indication signal is configured to identify a first transmission synchronization mode of the second node. The first node may then adjust its communications configuration in response to the indication signal. In making such adjustments, the first node may either contend for communications on the shared communication channel using the first transmission synchronization mode or refrain from attempting the communications on the shared communication channel using a second transmission synchronization mode.
