Abstract: A dynamic BSS color feature for co-hosted virtual access points is described. An example of a storage medium includes instructions to operations including enabling, by an access point, a dynamic basic service set (BSS) color feature for operation with multiple virtual access points (VAPs) hosted by the access point; switching a parameter of the access point to indicate that no co-hosted BSS is present; assigning a different BSS color to each of the VAPs; performing access point operations, including utilizing the assigned BSS colors for transmissions relating to any of the VAPs; and disabling the dynamic BSS color feature upon occurrence of one or more conditions.

Abstract: A method for wake-up radio group ID (GID) allocation includes generating, by an access point and prior to a station associating to the access point, a first Group-ID and a second Group-ID, wherein the station comprises a Wake-Up Radio, receiving, by the access point, a request from the station to associate, determining, by the access point, whether the station belongs in the first Group-ID or the second Group-ID, assigning, by the access point and based on the determining, the station to the first Group-ID, and sending, by the access point, a Wake-Up Packet to the Wake-Up Radio of the station using the first Group-ID.

Abstract: Systems and methods for uplink Resource Unit scheduling include receiving, by a network device and from each of a plurality of stations, a status of a buffer, determining for each of the plurality of stations, by the network device, whether the status of the buffer of a particular station exceeds a first threshold, a second threshold, or neither the first threshold or the second threshold, in response to the buffer of the particular station exceeding the first threshold, scheduling the particular station using Uplink Multi-User Multiple Input Multiple Output, in response to the buffer of the particular station exceeding the second threshold, scheduling the particular station using a scheduled RU, and in response to the buffer exceeding neither the first threshold or second threshold, scheduling the particular station using a random-access resource unit (RA-RU).

Abstract: Examples described herein provide enhanced client grouping by a network device. Examples include determining that a plurality of client devices each comprising a plurality of receiver antennas are associated with a network device, and grouping the client devices into one or more groups, wherein each group comprises a number of client devices less than or equal to the number of transmitter antennas of the network device. Examples include, for each group, assigning one spatial stream to one receiver antenna for each client device of the group, and based on a determination that the number of client devices of the group is greater than one and less than the number of transmitter antennas, assigning one spatial stream to each of a portion of the remaining receiver antennas of the group, wherein at least one receiver antenna of the group is not assigned a spatial stream.

Abstract: This disclosure is directed to controlling a wake-up radio (WUR) in a wireless station side client device (STA-device). In one example, after the STA-device has received negotiation parameters from a wireless access point (AP) to establish a wireless association as a network connection between the STA-device and the AP. The PCR may be disabled in favor of the WUR. The WUR, which may use less power than the PCR, may then monitor for Beacon Frames (e.g., in the disclosed beacon loop) and Discovery Frames (e.g., in the disclosed discovery loop). Based on a state machine, that may be implemented as computer instructions executed by a hardware processor of the STA-device. Generally, the STA-device may use the WUR and state machine implementation to determine a proper time to re-enable the PCR for communication with the AP.

Abstract: Examples provided herein describe a method for managing power consumption of a network. For example, a network device may monitor a set of network area zones of a network coverage area, where each network area zone is associated with a set of edge devices. A first occupancy state may be determined for a first network area zone of the set of network area zones based on usage of a first set of edge devices of the first network area zone. Based on the determined first occupancy state, a first power consumption policy for the first network area zone may be determined. Responsive to determining the first power consumption policy, the determined first power consumption policy may be applied to the first set of edge devices in the first network area zone at least edge changing a power consumption mode of a first edge device in the first set of edge devices.

Abstract: A method including selecting multiple dedicated radios on a transmission channel and programming multiple association identifiers on each dedicated radio is provided. Each of the association identifiers is configured to detect a resource unit assigned to one of multiple stations. The method includes providing multiple packets collected from the dedicated radios to a server and merging the packets from the dedicated radios to identify at least one station. Merging the packets includes identifying a preamble in the packets from the dedicated radios, matching the preamble from different dedicated radios, combining a data portion of the packets from different dedicated radios whose preamble match, selecting a time-stamp from one of the dedicated radios, and associating the time-stamp with the data portion. A system and a non-transitory, computer readable medium storing instructions to perform the above method are also provided.

Abstract: Systems and methods for calculating uplink pathloss in a wireless local area network are provided. Uplink pathloss between an access point and client device operating in the wireless local area network can be calculated based on determining an effective maximum transmit power. Based on the effective maximum transmit power, and known uplink power headroom, a current transmit power of the client device can be determined. Based on the current transmit power of the client device, uplink pathloss can be determined. If the operating conditions and/or characteristics of the client device and/or wireless local area network change, the uplink pathloss may be re-evaluated.
