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.

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.

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.

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.

An apparatus includes a memory and a processor coupled to the memory. The processor is configured to determine a first identifier that corresponds to a data link group identifier of a data link group and to determine a second identifier that corresponds to a device. The processor is further configured to generate an internet protocol (IP) address for a data link interface of the device based on a combination of a data link routing prefix, the first identifier, and the second identifier.

Methods, systems, apparatuses, and devices are described for access point privacy using media access control (MAC) address randomization. The access point may identify a MAC address for use with over-the-air (OTA) transmissions and a persistent MAC address for backend communications. The access point may communicate the OTA MAC address and the persistent MAC address to a wireless station. The access point and the wireless station may exchange data frames and perform MAC replacement techniques to map the OTA MAC address to the persistent MAC address. The persistent MAC address may provide for data routing, mobility management, etc., whereas the OTA MAC address may provide for privacy for the wireless transmissions.

One aspect of this disclosure provides a method of wireless communication. The method includes generating, by an apparatus, an aggregated media access control protocol data unit (A- MPDU) frame comprising a plurality of A-MPDU sub-frames, wherein at least one sub- frame of the plurality of A-MPDU sub-frames is addressed to at least a first device and at least one other sub-frame of the plurality of A-MPDU sub-frames is addressed to at least a second device. The method comprises inserting an indication that the A-MPDU frame is addressed to at least the first and second devices into a physical layer convergence procedure (PLCP) protocol data unit (PPDU) field.

Systems and methods for signaling multi-destination aggregated multi-user media access control protocol data units in a wireless network

Methods and apparatus are described for efficiently suppressing transmission of signals from devices which are using a first protocol, in order to allow the frequency spectrum being used by devices using the first protocol to be used briefly for communication between devices using an alternative communications protocol. In some embodiments, the first protocol is WiFi and the alternative signaling protocol is a non-WiFi peer to peer communications protocol. A wireless communications device, e.g., a peer to peer wireless communications device, generates a signal suppression utility metric (SSUM). The signal suppression utility metric provides an indication of how useful transmitting a transmission suppression signal, e.g., a S-CTS signal which may be a CTS to self signal, will be at a given point in time. The wireless communications device decides whether or not to transmit a transmission suppression signal as a function of the signal suppression utility metric.

Methods, devices, and computer program products for optimization of branch synchronization node determination in a peer-to-peer network are disclosed herein. In one aspect, a higher-level node, such as a root node broadcasting master clock synchronization messages to other devices, may determine a dynamic signal strength threshold and send it in those synchronization messages. After receiving those messages, if finding the received signal strength of those messages is below the dynamic signal threshold, a receiving node will realize that it is relatively far away from the root node and hence may be a potential branch node to further relay those messages. This dynamic threshold may be determined to ensure that at least a certain percentage of receiving nodes are potential branch nodes, based on the received signal strengths of those nodes at the root node. This method can reduce device energy consumption by only requiring edge devices to relay the synchronization messages, and they can be dynamically identified based on the threshold. In addition, a branch node can also use the dynamic signal strength threshold to help the determination of its potential next-hop branch nodes.
