13 results about "Beacon interval" patented technology

Systems and methods for detecting node outages in a mesh network are disclosed. A tracking node in the mesh network detects a set of signals originating from a tracked node in the mesh network. The set of signals includes beacons or communication messages sent by the tracked node. The tracking node determines that a threshold number of beacon intervals have elapsed since a most recent signal was received from the tracked node. The tracking node performs an outage verification based on data received from another node in the mesh network and updates a state of the tracked node. Based on the updated state, the tracking node outputs a probe to the tracked node, which requests a response to the probe. When no response to the probe is received from the tracked node, the tracking node sends an outage alert message to a next topology higher layer of the mesh network.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may transmit a channel switch announcement indicating a time by which a channel switch is to occur, wherein the time for the channel switch is less than a beacon interval from the time by which the channel switch announcement is transmitted. The wireless communication device may perform the channel switch in accordance with the channel switch announcement. Numerous other aspects are described.

The ML element contains common information and link information. The link information includes information about a beacon interval of the second transmitting STA.

The present disclosure provides methods, assemblies, devices, and systems for flexible beacon interval operation. Some aspects more specifically relate to including indications of static and dynamic beacon intervals in beacon frames and other frames. In some examples, an AP may transmit a frame including a plurality of indications of a plurality of beacon intervals, such as an indication of a static beacon interval and an indication of a dynamic beacon interval. The AP may then transmit a frame, such as a beacon frame, at a time associated with the beacon interval.

Methods and systems are described for managing SSIDs in a wireless network. An AP providing wireless communications may determine that there is high or low network traffic associated with one of its SSIDs. For example, a high or low number of computing devices may be probing the AP on a particular SSID. The AP may enable or disable the SSID on additional channels, increase or decrease its beacon interval, and / or increase or decrease its beacon physical layer (PHY) data rate in order to provide probing computing devices with greater or less access to the SSID based on the network activity. The AP may scan its channels for network activity and determine the appropriate changes to its SSIDs in order to improve access to heavily used SSIDs or to free up resources.

This disclosure provides methods, components, devices and systems for advanced notification of critical updates. Some aspects more specifically relate to transmission of an indication of a critical update at least a threshold duration prior to the critical update occurring, where the indication of the critical update includes a time at which the critical update is to occur. In some implementations, the time at which the critical update is to occur may be indicated via a difference between a time at which the indication of the critical update is received and the time at which the critical update is to occur, via a quantity of beacon intervals, via an absolute time reference, or any combination thereof. Additionally, or alternatively, the indication of the critical update may include an indication of one or more communication links for which the critical update applies, additional information about the critical update, or both.

A target AP provides a neighbourhing AP with information about a TWT schedule in the target BSS, together with additional information such as a Buffer Status Report (BSR) of the target first BSS, a low latency data scheme of the target BSS reporting one or more prioritized TID in the target BSS, a SP splitting scheme of the TWT SPs reporting a breakdown of a service period (SP) within a Beacon interval of the target BSS, a reciprocal OBSS TWT indication reporting an agreement of the target AP to provide a second OBSS TWT schedule in the target BSS timely aligned with a second TWT schedule in the second BSS. The neighbouring AP can then configure an OBSS TWT schedule in its BSS based on the received information, to protect the TWT schedule of the target BSS. The OBSS TWT schedule is timely aligned with the TWT schedule.

Disclosed are a listen interval-based transmission or reception method and device for an access point (AP) multi-link device (MLD) supporting power saving (PS) in a wireless LAN system. The method according to an embodiment of the present disclosure may comprise the steps in which: a non-AP station (STA) affiliated with a non-AP MLD receives, from one or more APs affiliated with an AP MLD, at least one of first information related to whether a PS mode is supported or second information related to whether the PS mode is enabled; and the non-AP STA determines a listen interval on the basis of one or more beacon intervals related to the one or more APs.

A low power Wi-Fi device that executes the Matter protocol is disclosed. The Wi-Fi device changes its mode of operation based on the status of the Matter protocol. The device monitors the state of Matter subscriptions. Until one or more subscriptions are established, the low power Wi-Fi device operates in DTIM mode, wherein the device wakes for every DTIM beacon. Once a subscription is established, the low power Wi-Fi device operates in Listening Interval mode, wherein the device wakes once per listening interval. The listening interval is a multiple of the beacon interval and is greater than the DTIM beacon interval. This transition reduces the power consumption of the device.

A method performed by a non-access point (AP) multi-link device (MLD) is disclosed. The method according to one embodiment of the present disclosure comprises the steps of: receiving, by a first station (STA) affiliated to a non-AP MLD, a first frame from an AP MLD, the first frame including first information related to a current mode of a first AP affiliated to the AP MLD and second information related to a state of the first AP; and decoding the first frame by the first STA, wherein a listen interval between the non-AP MLD and the AP MLD is based on at least one beacon interval of at least one AP among a plurality of APs included in the AP MLD, and wherein a mode of the at least one AP may be at least one of an active mode and a dynamic power saving (PS) mode.

Methods and apparatus are provided that enable an AP MLD to indicate to one or more non-AP MLDs their recommended wake-up times on one or more links. In some embodiments, the recommended wake-up time may be continued for at least one STA over a prescribed number of intervals. Features are also provided for the STA to request wake-up time recommendations from the AP as well as rules that the STA adheres to. In one aspect of the present disclosure, an AP transmits a wakeup time recommendation element (WTRE) in a beacon interval. The WTRE includes a recommendation to recommend one, multiple, or all stations to postpone their wake-up time to a recommended wake-up time, rather than an immediate wake-up time.
