Abstract: An apparatus for implementing power control for a radio device that has multiple radio transceivers operating in different bands, including sub-bands of a single frequency band. The device implements a power control protocol for communications between the device and a similar peer device. The device sets-up the power control protocol by generating a request to use one of the multiple bands to signal power control operations, and to use another one of the multiple bands to transfer data between the device and the peer device. The device sends the request to the peer device and receives a response. Based on the response, the device identifies a control channel band and a data channel band from among the multiple bands.

Abstract: This disclosure describes systems, methods, and devices related to a multiuser multiple-input and multiple-output (MU-MIMO) setup frame. A device may generate an MU-MIMO setup frame comprising a physical layer (PHY) header and a media access control (MAC) header, the PHY header comprising an indication of a control trailer after the MAC header, the MAC header comprising a first receive address (RA) field comprising one or more first device identifiers (IDs), and the control trailer comprising a second RA field comprising one or more second device IDs. The device may transmit the MU-MIMO setup frame over a directional multi-gigabit (DMG) channel.

Abstract: Embodiments of an access point (AP) may comprise memory and processing circuitry coupled to the memory, and transceiver circuitry coupled to the processing circuitry. The processing circuitry of the AP may be configured to encode a trigger frame to allocate a center 26 tone RU of an 80 MHz channel for an HE-trigger-based PPDU, the center 26 tone RU having an adjacent upper 20 MHz subchannel and an adjacent lower 20 MHz subchannel. In an embodiment, the center 26 tone RU is for a station (STA) and wherein the trigger frame indicates to the STA to transmit a pre-HE-STF preamble on one of the adjacent upper 20 MHz subchannel, the adjacent lower 20 MHz subchannel, or both the adjacent upper and lower 20 MHz subchannels, and configure the wireless device to transmit the trigger frame to the station.

Abstract: Some embodiments relate to methods, computer readable media, and apparatus for resolving acknowledgements between associated and unassociated stations. An apparatus is disclosed including processing circuitry configured to decode responses to a random-access trigger frame, wherein one of the responses is a response from an unassociated station. The processing circuitry may be further configured to: encode an acknowledgement to acknowledge receipt of the response from the unassociated station, where the acknowledgement comprises an indication that the acknowledgement is for the unassociated station, and where the acknowledgement further comprises a media access control (MAC) address of the unassociated station in a field of the acknowledgement other than a field in a MAC header portion of the acknowledgement. The processing circuitry may configure the HE access point to transmit the acknowledgement.

Abstract: Computer readable media, methods, and apparatuses for centralized channel access for primary and secondary channels are disclosed. An apparatus is disclosed comprising memory and processing circuitry. The processing circuitry is configured to encode a schedule of one or more resource allocations, wherein each resource allocation comprises a type of allocation, a bandwidth, an indication of a channel, a source association identification (AID), a destination AID, an allocation start, and a duration. The type of allocation may be a service period (SP) or a contention-based access period (CBAP). The channel may be an indication of a basic service set (BSS) or a personal BSS (PBSS) primary channel, BSS or PBSS secondary channel, or BSS or PBSS tertiary channel. The processing circuitry may be configured to transmit the schedule to one or more stations identified by the source AID and the destination AID of the one or more resource allocations.

Abstract: Techniques for power saving by remote wireless mobile devices are provided, in particular by stations (STAs) during downlink (DL) multiple-user multiple-input and multiple-output (MU-MIMO) transmissions in an Institute of Electrical and Electronics Engineers (IEEE) 802.11ay network when reverse direction (RD) transmissions are either enabled and not enabled. Various embodiments enable each STA in a group of STAs to determine an order in which the STAs are requested to send a block acknowledgement (BACK) and which STAs will be granted an RD transmission. Further, a duration of each RD transmission is provided to each STA. Based on the provided information, each STA can determine times to enter a power saving mode. Other embodiments are described and claimed.
