    Abstract: Systems and methods are provided for optimizing the scheduling of Orthogonal Frequency-Division Multiple Access (OFDMA) transmissions in the downlink (DL) direction. A two-stage mechanism can be implemented when effectuating DL OFDMA transmission involving multiple modulation and coding schemes (MCS) in a single transmit burst. A first stage of the two-stage mechanism may use radio frequency (RF) boosting/de-boosting of Resource Units (RUs) such that the average input power to an AP power amplifier (PA) may remain under a saturated PA output power to ensure PA linearity. If RF boosting/de-boosting is not supported, an alternative mechanism for OFDMA grouping (to rigid grouping) can be employed to skip higher MCS.

    Abstract: Systems and methods for partitioning radio spectrum in an AP to support a mixed client environment while maintaining efficient 802.11ax transmissions is provided. Clients in a zone may be categorized into 802.11ax and legacy clients, and those clients may further be categorized into a majority population and a minority population. Assignment of the minority and majority populations can be effectuated by considering the number of available channels to be assigned to each population of client devices, as well as steering load/cost and a client device's ability to be steered to another channel. Moreover, assignment of the minority and majority populations can take into account maintaining a particular client-channel density.

    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 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: Example implementations relate to multicast multi-user grouping. For example, an apparatus may comprise a processing resource that may rank a plurality of stations associated with the apparatus based on a characteristic associated with a first multicast group containing a first set of stations among the plurality of stations, and a characteristic associated with a second multicast group containing a second set of stations among the plurality of stations. The processing resource may assign a first group of stations from the first multicast group and the second multicast group to a first multi-user group and assign a second group of stations from the first multicast group and the second multicast group to a second multi-user group. The processing resource may convert a multicast frame associated with a station from the first multi-user group to a unicast frame, and transmit the unicast frame to each station in the first multi-user group.
