    Abstract: Logic to generate, by an access point (AP) station (STA), a medium access control (MAC) resource assessment trigger frame to transmit during a first transmission opportunity (TxOP), the MAC resource assessment trigger frame to allocate a portion of the first TxOP to a first STA and to request a first resource assessment from a first group of STAs for evaluation by the first STA, the first resource assessment to assess peer-to-peer (P2P) data transfers between the first group of STAs and the first STA. Logic to cause transmission of the MAC resource assessment trigger frame to the first STA and the first group of STAs. And logic to receive one or more short term resource assessment frames from the first group of STAs, the one or more short term resource assessment frames each comprising an indication of resources for a data transfer.

    Abstract: Logic to place one or more protocol data units (PDUs) in a transmit queue for transmission. Logic to perform a directional clear channel assessment (CCA) for a first sector of a 60 gigahertz (GHz) link, the directional CCA to determine only if the first sector is busy or idle. Logic to determine the directional CCA indicates idle for the first sector. Logic to cause transmission of the first PDU to the STA via the first sector of the 60 GHz link based on the directional CCA. Logic to receive an acknowledgement (ACK) of receipt of the PDU from the STA. Logic to perform a directional CCA for a second sector of the 60 GHz link. And logic to communicate via the first sector and the second sector independently.

    Abstract: Methods and apparatus to perform multi-band link aggregation in a wireless network are disclosed. An example apparatus includes a buffer controller to store (A) a first set of data packets that have been received on a first interface and (B) a second set of data packets that have been received on a second interface into a buffer, the first and second sets of data packets being received from a wireless device during a same time frame; and a window determiner to control a first bitmap corresponding to the first set of data packets received on the first interface and a second bitmap corresponding to the second set of data packets received on the second interface, a first size of the first bitmap and a second size of the second bitmap being smaller than a third size of the buffer.

    Abstract: This disclosure describes methods, apparatus, and systems related to media access control (MAC) range extension. A device may cause to append a training field to each of one or more beacon frames. The device may cause to send the one or more beacon frames directionally using a sector sweep to one or more responder devices during a first interval. The device may determine an extended schedule element to be sent to the one or more responder devices, the extended schedule element including one or more directional antenna sectors to be used by the device during a second interval. The device may identify a first frame from a first responder device, during the second interval, wherein the first frame is received on a directional antenna sector of the one or more directional antenna sectors corresponding to an operating sector of the first responder device.

    IPC: H04W76/14

    Abstract: Provided herein are apparatus and methods for signaling regulatory information and transmit power information for device-to-device communication. An apparatus for a Wi-Fi device comprising: a RF interface; and processor circuitry coupled with the RF interface. The processor circuitry is to: decode a first discovery frame received from a peer Wi-Fi device via the RF interface to obtain a first Operation Information attribute of the peer Wi-Fi device, wherein the first Operation Information attribute is to indicate a first operation mode of the peer Wi-Fi device; and encode, in response to the first discovery frame, a second discovery frame for transmission to the peer Wi-Fi device via the RF interface, wherein the second discovery frame includes a second Operation Information attribute of the Wi-Fi device to indicate a second operation mode of the Wi-Fi device. Other embodiments may also be disclosed and claimed.

    Abstract: Provided herein are techniques for AP coordinated P2P communications in a Wi-Fi network. Embodiments describe an apparatus for an AP including processing circuitry to: encode a first trigger frame, to be transmitted to a plurality of STAs associated with the AP, to query a buffer status of each STA; receive one or more response frames from one or more of the plurality of STAs, each having data to be transmitted to a target receiver STA in the plurality of STAs; allocate one or more RUs for each of a group of STAs selected from the one or more STAs, based on the one or more response frames, and using OFDMA; and encode a second trigger frame, to be transmitted to the selected group of STAs and the target receiver STA for each of the group of STAs, to indicate the allocation of RUs.

    Abstract: This disclosure describes methods, apparatus, and systems to increase the transmission data rate in wireless networks, for example, by using one or more Multiple Input Multiple Output (MIMO) and/or channel bonding techniques. In one embodiment, the disclosure describes the use of Golay Sequence Sets (GSS) to define guard intervals (GIs) for single carrier (SC) single channel bonding and multiple input multiple output (MIMO) transmission. In various embodiments, the disclosure describes the design of guard interval sequence for 3 types of guard intervals having lengths that can be classified as short, medium, and long. In another embodiment, the disclosure defines the guard interval for single channel transmission channel bonding and for MIMO transmission.
