Abstract: Embodiments of methods for scanning in a directive multi-gigabit network are generally described herein. An apparatus of a station may include processing circuitry configured to decode a sector sweep beacon received from an access point, encode for transmission a sector sweep feedback message to include a beam refinement protocol (BRP) request, and encode for transmission BRP responses to BRP signaling received from the access point. The processing circuitry may be further configured to decode a link margin feedback signal received from the access point to determine an access point link margin, measure signal information associated with the link margin feedback signal to determine a received link margin measurement, and encode signaling for association with the access point based on the access point link quality and the receive link quality.

Abstract: Some demonstrative embodiments include apparatuses, devices, systems and methods of communicating an Enhanced Directional Multi Gigabit (EDMG) support indication. For example, a wireless station may be configured to generate a frame having a structure compatible with a Directional Multi Gigabit (DMG) frame structure, the frame including an EDMG supported field to indicate that the wireless station supports one or more EDMG features; and to transmit the frame over a DMG channel.

Abstract: Some demonstrative embodiments include apparatuses, devices, systems and methods of communicating a Physical Layer Convergence Procedure (PLCP) Protocol Data Unit (PPDU). For example, an apparatus may include circuitry and logic configured to cause a wireless station to transmit a first PPDU to a second wireless station, the first PPDU including a preamble, a header, and a first PLCP Service Data Unit (PSDU), the header including a synchronization (sync) indicator to indicate that the second wireless station is to synchronize a second PPDU to the first PPDU; and to receive the second PPDU from the second wireless station, the second PPDU spaced from the first PPDU by less than a Short Inter Frame Space (SIFS), the second PPDU including a Byte Count, and a second PSDU, the second PPDU including no preamble or a short preamble, which is shorter than the preamble of the first PPDU.

Abstract: Devices and methods of for wireless communication in a directional multi-gigabit (DMG) band are generally described. A device can detect a starting point of an awake window (AW). The device can encode a first announcement traffic indication message (ATIM) for directional transmission, after no more than a point coordination function (PCF) interframe space (PIFS) subsequent to the starting point, over a first beamformed link to a first station (STA). The device can encode a second ATIM for directional transmission subsequent to directional transmission of the first ATIM, within the AW and in a different direction than the directional transmission of the first ATIM, over a second beamformed link to a second STA. Other devices, systems and methods are also described.

Abstract: In single user OFDM wireless communication, the serial bit stream in a Medium access control Protocol Data Unit (MPDU) to be transmitted may be split up and routed in parallel through different encoding modules. In one embodiment the entire bit stream may be processed through an LDPC, and the output of the LDPC module split up before being routed to different Modulation Modules that each select a separate MCS for the associated sub-band. In another embodiment the bit stream may be split up before being processed separately through multiple LDPC modules, and the output of each LDPC module may then be routed to a different associated Modulation Module for selection of a separate MCS for the associated sub-band.

Abstract: This disclosure describes methods, apparatus, and systems related to providing a source device more degrees of freedom in the performing CCA, and in using CCA for communicating with neighboring devices. Before accessing the channel, a source device may need to perform carrier sense multiple access with collision avoidance (CSMA/CA), the CSMA/CA additionally comprising CCA. In various embodiments, CCA can be performed either using quasi-omnidirectional receiving antenna(s), or using directional receiving antenna(s). In one embodiment, one or more requisite conditions for performing directional CCA can be specified. In another aspect, sensitivity level adjustments can be provided when performing directional CCA and/or quasi-omnidirectional CCA.

Abstract: Techniques for group-based spatial stream assignment signaling in 60 GHz wireless networks are described. According to various such techniques, a 60 GHz-capable transmitting device may be configured to define one or more DL MU-MIMO groups, each of which may comprise one or more respective 60 GHz-capable receiving devices. In various embodiments, the 60 GHz-capable transmitting device may include a DL MU-MIMO group ID within DL MU-MIMO control information in a PHY header of a PPDU in order to indicate that the PPDU is directed to a DL MU-MIMO group corresponding to that DL MU-MIMO group ID. In some embodiments, DL MU-MIMO control information may comprise information specifying spatial stream assignments for the 60 GHz-capable receiving devices of that DL MU-MIMO group. Other embodiments are described and claimed.

Abstract: Certain embodiments herein are directed to enabling service interoperability functionality for wireless fidelity (WiFi) Direct devices connected to a network via a wireless access point. A WiFi Direct device may identify various other WiFi Direct devices on a WiFi network for performing a requested service, such as printing content or displaying content to a screen. In so doing, the device may share information associated with an access point to which the device is connected with the other devices, which may also share information associated with an access point to which they are connected. In this way, WiFi Direct devices may discover their connectivity with respect to other devices to utilize a broader array of connection options for implementing a desired service, and hence, may leverage application programming interface (API) modules directed at providing service interoperability functionality between software applications and services requested by the software applications.
