Abstract: Embodiments of an access point (AP), station (STA) and method of communication are generally described herein. The AP may be configurable for multi-band operation in a plurality of frequency bands, each frequency band comprising one or more channels. The AP may select a subset of the frequency bands for which the AP is to request per-band channel availability information from the STA. The AP may transmit a Trigger Frame (TF) for a multi-band bandwidth query report polling (MB-BQRP) to request the per-band channel availability information. The AP may receive an uplink frame that includes a multi-band bandwidth query report (MB-BQR) that indicates the per-band channel availability information. The AP may determine, based on the MB-BQR, for an uplink transmission by the STA: one or more frequency bands of the subset of frequency bands, and one or more corresponding channels.

Abstract: Methods and apparatus implementing Hardware/Software co-optimization to improve performance and energy for inter-VM communication for NFVs and other producer-consumer workloads. The apparatus include multi-core processors with multi-level cache hierarchies including and L1 and L2 cache for each core and a shared last-level cache (LLC). One or more machine-level instructions are provided for proactively demoting cachelines from lower cache levels to higher cache levels, including demoting cachelines from L1/L2 caches to an LLC. Techniques are also provided for implementing hardware/software co-optimization in multi-socket NUMA architecture system, wherein cachelines may be selectively demoted and pushed to an LLC in a remote socket. In addition, techniques are disclosure for implementing early snooping in multi-socket systems to reduce latency when accessing cachelines on remote sockets.

Abstract: Methods, apparatuses, and computer readable media for power reduction in a wireless network are disclosed. An apparatus of a first access point is disclosed comprising processing circuitry configure to decode a first PPDU, the first PPDU including a trigger for control (TOC) frame, the TOC frame comprising resource allocations for deferral transmissions, the TOC frame including a first duration field indicating a duration of a transmission opportunity (TXOP). The processing circuitry may be further configured to respond to a determination that the TOC frame includes a resource allocation by encoding a second PPDU including a preamble portion and a media access control (MAC) portion including a receive with condition (ARC) frame, the ARC frame including a second duration field indicating a remaining duration of the TXOP, an address field indicating a MAC address of the first AP, and a condition field indicating a condition.

Abstract: Embodiments of an access point (AP), station (STA) and method for full-duplex (FD) communication are generally described herein. The AP may contend for a transmission opportunity (TXOP) during which the AP is to control access to channel resources. During the TXOP, the AP may request to receive uplink data demands from a first group of STAs; receive the uplink data demands; allocate, based at least partly on the uplink data demands, resource units (RUs) of the channel resources for an OFDMA transmission of uplink data; and schedule a full-duplex (FD) communication in which the AP is to use overlapping portions of the channel resources during overlapping time periods of the TXOP to receive the uplink data and to transmit downlink data to a second group of one or more STAs.
