Described herein are technologies related to an implementation of interference mitigation in a receiver of a portable device. A preemptive-automatic gain control (AGC) system mitigates a collocated or external interfering signal in a receiver of a portable device. The receiver of the portable device receives and processes a data packet of a first radio frequency (RF) signal that includes a Bluetooth (BT) signal, a Wi-Fi signal, a near field communications (NFC), 3G, 4G, or the like. During the processing of the data packet, a collocated or an external second RF signal is detected and received by the receiver. The second RF signal includes an interfering Bluetooth (BT) uplink transmission, a near field communications (NFC) transmission signal, a Wi-Fi transmission signal, 3G or 4G uplink transmission, an LTE signal, or the like.

Preemptive automatic gain control (AGC) for interference mitigation

A mobile device may include a Short Range radio communication subsystem and a Cellular Wide Area radio communication subsystem. The Short Range radio communication master subsystem may include a processing circuit configured to identify a first plurality of channels, assign a blocking priority to one or more of the first plurality of channels, identify a second plurality of channels occupied by the Cellular Wide Area radio communication subsystem, and select a third plurality of channels from the first plurality of channels based on the blocking priority of the first plurality of channels and the frequency distance between each of the first plurality of channels and each of the second plurality of channels, and a radio transceiver configured to apply the third plurality of channels to transmit or receive data on a Short Range radio communication network.

Methods in short range radio communication master subsystems, mobile devices, and multi-mode radio communication systems

Techniques for employing channel inhibition (CI) with adaptive frequency hopping (AFH) in connection with Bluetooth (BT) are discussed. One example system employing such techniques comprises a BT master component operating on a plurality of channels via AFH; and a processor configured to: assign, based on a set of criteria, a first (e.g., 'UNUSED') status and a priority level to one or more channels, and a second (e.g., 'USED') status to each other channel; determine whether a total number of channels set as &#x2018;USED&#x2019; is less than a minimum number of required channels; and in response to a determination that the total number of channels set as &#x2018;USED&#x2019; is less than the minimum number, repeatedly assign a &#x2018;USED&#x2019; status to a channel having a lowest priority level among channels with the &#x2018;UNUSED&#x2019; status, until the total number of channels set as &#x2018;USED&#x2019; equals the minimum number.

Adaptive frequency hopping (AFH) with channel inhibition (CI) for bluetooth

Embodiments pertain to systems, methods, and component devices for Tx-Tx transmit concurrency by combining signals before power amplification. One example embodiment includes validity check circuitry configured to check a transmission power for a Bluetooth signal against a first threshold transmission power, a Bluetooth Power Amplifier, and a WLAN power amplifier. A switching network controlled by the validity check circuitry and configured to couple the Bluetooth input to Bluetooth power amplifier input when the transmission power for the Bluetooth signal is above the first threshold transmission power and to couple the Bluetooth signal with a WLAN signal for input to the shared WLAN power amplifier when the transmission power for the Bluetooth signal is less than the first threshold transmission power.
