    Abstract: One or more embodiments describe controlling audio signals at a user device during a communication session between the user device and a remote node, in which a primary audio signal is received at audio input means of the user device for transmission to the remote node in the communication session. It is determined whether the user device is operating in a first or a second mode. In dependence upon determining that the user device is operating in the first mode, the secondary audio signals are selectively suppressed from being output from the user device during the communication session.

  • Patent number: 9648518
    Abstract: A device may store a plurality of different coexistence profiles for different possible communication scenarios. The device may be initialized with a first one of the coexistence profiles, and may operate to dynamically switch to different ones of the coexistence profiles based on current conditions. Each coexistence profile may include a number of coexistence related parameters stored as a plurality of data structures. During device use, the device may dynamically select an appropriate coexistence profile based on the current communication conditions, such as Wi-Fi RSSI, Bluetooth RSSI, and/or the number of Wi-Fi and/or Bluetooth devices with which communication is currently occurring, among other possible factors. The coexistence profile is selected to provide the best possible Wi-Fi and/or Bluetooth output performance based on current conditions. The device may repeatedly dynamically select different coexistence profiles as conditions change, e.g.

  • Patent number: 9641226
    Abstract: A mobile device and method for performing a function using a short-range communication tag are provided. In the method, the mobile device inputs function-related information into a short-range communication tag, and recognizes proximity to or contact with the short-range communication tag. Then the mobile device reads the function-related information from the short-range communication tag, and performs a function correlated with the function-related information. This allows performing various functions of the mobile device, only depending on a user's action to bring the mobile device in proximity to or contact with the Near Field Communication (NFC) tag.

    Abstract: A wireless communication device for transceiving heterogeneous radio-frequency (RF) signals is provided. The wireless communication device includes a first antenna, a second antenna, a first transceiver, a second transceiver and a controller. The first transceiver controls the first antenna through a first transceiving path to transceive a first RF signal according to a first wireless communication standard. The second transceiver controls the second antenna through a second transceiving path to transceive a second RF signal according to a second wireless communication standard. In a joining process when the wireless communication device establishes connection to an end device according to the second wireless communication standard, the controller reduces transmission power for transmitting the first RF signal, or reduces sensitivity for receiving the second RF signal.

  • Patent number: 9549319
    Abstract: A first device wirelessly transmits beacon frames having distinct identifying contents within each. The first device issues a request to a second device to report what beacon frame contents the second device may have received. The second device sends a response to the first device. The first device analyzes the response in view of the beacon frame contents actually sent, the respective radio-frequency broadcast power of the beacon frames, and so on. Based on the analysis, the first device may determine proximity or other information regarding the responsive other device.

  • Patent number: 9525447
    Abstract: Because of associated disadvantages of narrow-band off-chip radio-frequency (RF) filtering, a mixer-first receiver front-end designed to tolerate blockers with reduced gain compression and noise factor degradation is disclosed. The mixer-first receiver front-end includes two separate down-conversion paths that help to reduce added noise and voltage gain prior to baseband filtering, which are critical factors in eliminating narrow-band off-chip RF filtering. The mixer-first receiver front-end can be used to support down-conversion of multiple different communication signals (e.g., cellular, WLAN, and WPAN communication) with different center frequencies.

  • Patent number: 9426680
    Abstract: A multichannel radio receiver configured for real-time radio channel assessment is described herein. In one example, a radio frequency (RF) front end provides a frequency spectrum which is converted into a digitized spectrum. Within a digital subsystem, resources (e.g., software or a hardware device) may analyze channels or portions of spectrum within the digitized spectrum for a packet error rate (PER) at a plurality of power levels and a plurality of modulation schemes. The analysis may result a required received signal strength indicator (RSSI) that is needed to result in a particular read reliability requirement (RRR). Using the required RSSI, endpoints communicating with the multichannel radio may be associated with a channel(s), modulation scheme(s) and/or power level(s) that results in the RRR. The analysis may be performed by one or more resources operating in parallel and operating in the background to other communications between the endpoints and multichannel radio receiver.
