Server-assisted device-to-device discovery and connection

Abstract: A method includes receiving, at a network node, a device-to-device D2D discovery request from a first device and sending a D2D discovery response from the network node to the first device. The D2D discovery response includes information associated with a second device that is available to establish a D2D connection with the first device. The network node may perform inquiries regarding D2D connection permission from both devices. If D2D connection is permitted by both devices, the network node may facilitate the D2D scanning by sending each device's scanning information to the other device via a non-D2D link. In parallel to D2D scanning, the network node may speed up D2D link setup by distributing, via non-D2D links, link setup information to each device, where the link setup information may include device credential(s), IP address allocation(s), and/or group owner assignment.

Method and apparatus for flow control of data in a mesh network

Abstract: Flows admitted to a mesh node may be controlled through contention access parameters. The admitting node may determine a desired transmission opportunity duration, and a transmission opportunity frequency. Furthermore, the node may achieve the flow rate and delay bound requirements of the admitted flow based at least in part upon the desired transmission opportunity duration, and the transmission opportunity frequency. The data rate and the access frequency of the admitted node may be monitored at the physical access level. The flow rate requirement may be accomplished based at least in part upon an adjustment to the transmission opportunity duration. The delay bound requirement may be accomplished at least in part upon manipulation of the contention access parameters. The transmission opportunity duration and the access parameters may be determined by the upstream admitting nodes, which may reduce congestion near mesh portals, and accomplish increased data transfer.

Dynamic carrier sensing thresholds

Abstract: Systems and methodologies are described that facilitate communication in a wireless network environment. In particular, access points can dynamically adjust transmit power and/or carrier-sensing thresholds to allow multiple access points to communicate concurrently. In aspects, access points exchange node information, including RSSI and node addresses, of nearby nodes. The node information can be utilized to detect hidden nodes and estimate interference levels. Transmit power and/or carrier-sensing thresholds can be modified as a function of distance between source and destination access points, interference from hidden nodes, transmission rates, and/or path loss.

Systems and methods for wireless communication of packets having a plurality of formats

Abstract: Systems and methods for communicating packets having a plurality of formats are described herein. In some aspects, a signal (SIG) field in the preamble of a packet may indicate whether an extension field, such as an extension SIG field or SIG-B field, is included in the packet. In another aspect, one or more detectors may be used to auto-detect packets formatted as one of at least two different formats based on a short training field (STF) of a received packet. In some aspects, along training field (LTF) in the preamble of a packet may indicate whether the payload is repetition coded.

Method and apparatus for supporting adaptive channel state information feedback rate in multi-user communication systems

Abstract: Certain aspects of the present disclosure relate to techniques for achieving adaptive channel state information (CSI) feedback rate in multi-user communication systems. A rate by which CSI feedback can be transmitted from each user station of a wireless system to a serving access point may be adjusted based on evolution of a channel between that user station and the access point.

Information processing apparatus, information processing method and program

Abstract: A method is provided for modifying an image. The method comprises displaying an image, the image comprising a portion of an object; and determining if an edge of the object is in a location within the portion. The method further comprises detecting movement, in a member direction, of an operating member with respect to the edge. The method still further comprises moving, if the edge is not in the location, the object in an object direction corresponding to the detected movement; and modifying, if the edge is in the location, the image in response to the detected movement, the modified image comprising the edge in the location.

Method and apparatus to facilitate support for multi-radio coexistence

Abstract: A method of wireless communication includes monitoring coexistence issues among supported radios in a User Equipment (UE). The method includes determining a coexistence policy for communication resource operation within a user equipment (UE) and configuring communication resources of the user equipment in accordance with the determined coexistence policy. The policy may give priority to an LTE modem, an ISM modem, or may implement a variable priority scheme. The policy may be communicated to each modem from a host over a software messaging communication line. Modems in the UE may communicate with each other through logical lines providing real time communication. The policy may determine the operation of each modem and the treatment of the logical lines by each modem.

Voice trigger for a digital assistant

Abstract: A method for operating a voice trigger is provided. In some implementations, the method is performed at an electronic device including one or more processors and memory storing instructions for execution by the one or more processors. The method includes receiving a sound input. The sound input may correspond to a spoken word or phrase, or a portion thereof. The method includes determining whether at least a portion of the sound input corresponds to a predetermined type of sound, such as a human voice. The method includes, upon a determination that at least a portion of the sound input corresponds to the predetermined type, determining whether the sound input includes predetermined content, such as a predetermined trigger word or phrase. The method also includes, upon a determination that the sound input includes the predetermined content, initiating a speech-based service, such as a voice-based digital assistant.

Physical layer frame format for WLAN

Abstract: In a method for generating a data unit conforming to a first communication protocol, a first field and a second field to be included in a preamble of the data unit are generated. The first field includes a first set of one or more information bits that indicate a duration of the data unit and is formatted such that the first field allows a receiver device that conforms to a second communication protocol to determine the duration of the data unit. The second field includes a second set of one or more information bits that indicate to a receiver device that conforms to the first communication protocol that the data unit conforms to the first communication protocol. The first field and the second field are modulated using a modulation scheme specified for a field corresponding to the first field and the second field, respectively, by the second communication protocol.

Power receptacle wireless access point devices for networked living and work spaces

Abstract: Described herein are power receptacle wireless access point (AP) devices that may be used as part of a networked (smart) living and work space. These power receptacle wireless AP devices may be wall-mounted and/or retrofitted over existing electrical outlets or light switches, for providing wireless access to a room or region of a room. The power receptacle wireless AP device may connect via power line communication to a data connection.
