The present disclosure relates to systems and methods for operating a control signal to communicate signals using a first antenna and a first frequency band in response to determining that intra-device operations are occurring or are expected to occur, that a first amount of energy received by the first antenna is less than a threshold amount of energy, and that the first antenna is unaffected by the intra-device operations. The control signal may also delay communication of the signals in response to determining that intra-device operations are occurring, and that first amount of energy is greater than or equal to the threshold amount of energy.

Listen-before-talk systems, devices, and methods based on intra-device operations

Devices and systems useful in concurrently receiving and transmitting Wi-Fi signals and Bluetooth signals in the same frequency band are provided. By way of example, an electronic device includes a transceiver configured to transmit data and to receive data over channels of a first wireless network and a second wireless network concurrently. The transceiver includes a plurality of filters configured to allow the transceiver to transmit the data and to receive the data in the same frequency band by reducing interference between signals of the first wireless network and the second wireless network.

Multi-radio filtering front-end circuitry for transceiver systems

A technique for reducing interference on conducted RF links involves a determination of active wireless channels in an electronic device. For example, the device can determine whether there are any active cellular, WiFi, and/or Bluetooth channels. If so, any active channels can be removed from a list of possible channels that can be used for generating the RF signals for the conducted RF link. If any idle channels remain available, one or more may be selected for use for the conducted RF link. Those idle channels having a higher offset from any active channels may be given a greater weight in the selection since they should be less likely to be subject to interference. If not, one of the least crowded active channels may be selected for use for the conducted RF link.

Techniques for selecting conducted RF links for mitigating multi-radio coexistence

Apparatus and methods for performing simultaneous time division duplex (TDD) communications are disclosed. A wireless communication device can be configured to establish both a first TDD communication link and a second TDD communication link with a network, such as a telecommunication network. Thereafter, the wireless communication device can send TDD uplink data to the network via the first TDD communication link, and receive TDD downlink data from the network via the second TDD communication link, such that a portion of the TDD uplink data is sent to the network at the same time a portion of the TDD downlink data is received from the network. In this manner, the transmissions of TDD uplink data and the TDD downlink data can occur simultaneously, via multiple communication links. Further, the TDD downlink data can be received in multiple, coordinated data transmissions using Long Term Evolution (LTE) multiple-input and multiple-output (MIMO) antenna diversity.

Simultaneous operation of multiple time division duplex links using a single transceiver

Systems, methods, and devices are provided to efficiently share an antenna between multiple communication systems and allow for the communication systems to be simultaneously connected to the antenna with less attenuation and/or no fluctuation in signal strength. Communication circuitry may include an antenna that transmits and receives electromagnetic radiation. The communication circuitry may also include an antenna port that provides primary access to the antenna with a first attenuation via an antenna port input. Additionally, the communication circuitry may include a coupler attached to the antenna port. The coupler may provide secondary access to the antenna with a second attenuation.

Multi-radio front-end circuitry for radio frequency imbalanced antenna sharing system

A device and method selects an antenna configuration. The method performed at a user equipment includes determining at least one communication functionality that is being used, each communication functionality configured to utilize at least one antenna in a multi-antenna arrangement of the user equipment. The method includes receiving a first indication of whether a cellular communication functionality is being used, the cellular communication functionality configured to utilize at least one antenna in the multi-antenna arrangement. The method includes receiving a second indication of whether a coexistence condition is present. The method includes determining an antenna configuration for the multi-antenna arrangement to be used by the determined communication functionality based upon the determined communication functionality, the first indication, and the second indication. The method includes configuring the multi-antenna arrangement for the determined communication functionality based upon the antenna configuration.

Device and method for antenna synchronization and selection

Electronic devices may communicate with each other using a 'conducted RF link.' Such a conducted RF link is essentially a link that utilizes a conductor or cable that facilitates communication between electronic devices. Instead of the conductor carrying a traditional signal, it carries a modulated RF signal, such as those produced by a typical wireless RF radio like presently available WiFi/Bluetooth&#xae; cores.

Techniques for communicating using conducted RF links

To establish a connection between electronic devices some embodiments include a system, method, and/or computer program product for password pairing user-interface devices in wireless proximity. A first electronic device (e.g., a keyboard) transmits an advertising packet, and receives a password, where the password has been generated by a second electronic device (e.g., a smartphone) and the password enables pairing between the first electronic device and the second electronic device. The first electronic device transmits a message including the password to the second electronic device, where the second electronic device is within a predefined range of the first electronic device. In some embodiments the first device receives a command from the second electronic device to transition to a discovery mode, transitions to the discovery mode, and transmits a confirmation to the second electronic device that the first device is in the discovery mode.

Wireless proximity password pairing of user-interface devices

Devices at either end of a wireless communication link are each configured to support multiple different link settings. During communication, a device that is receiving data can monitor the signal quality and initiate a dynamic transition to a new link setting if performance of the current link setting falls below a lower threshold or exceeds an upper threshold. Dynamic link adaptation can be implemented within a wireless communication interface of the device and can be transparent to application and/or operating system software executing on the device.
