Abstract: Some demonstrative embodiments include devices, systems and methods of controlling communications of a multi-radio device. For example, a multi-radio device may include a cellular controller to control communication of a cellular radio; and a BT controller to control a transmission power of a BT radio according to a first power level, the BT controller is to receive from the cellular controller an indication of a cellular downlink period, and, during the cellular downlink period, to restrict a transmission power of at least one BT discovery packet to no more than a second power level, which is less than the first power level.

Abstract: 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.

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.

Abstract: Some demonstrative embodiments include devices, systems and methods of communication by co-located wireless communication modules. For example, a device may be configured to receive a latency attribute indicating an allowed latency to transmit a packet using one or more shared resources shared between a plurality of wireless communication modules; receive a first priority level indicating a first transmission priority of the packet; increase the first priority level to a second priority level based on a comparison between the allowed latency and a time from reception of the latency attribute; and send the second priority level to an arbitration module, the second priority level to indicate to the arbitration module a second transmission priority to transmit the packet using the shared resources.

Abstract: 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 ‘USED’ is less than a minimum number of required channels; and in response to a determination that the total number of channels set as ‘USED’ is less than the minimum number, repeatedly assign a ‘USED’ status to a channel having a lowest priority level among channels with the ‘UNUSED’ status, until the total number of channels set as ‘USED’ equals the minimum number.

Abstract: Some embodiments herein include at least one of systems, methods, and devices for power-efficient data transfer between two communicating devices. The two devices establish two wireless links between each other; the first link using a low-power/low-throughput protocol and utilized to maintain a second link, the second link using a high-power/high-throughput protocol. When first device data is available for transmission, the first device instructs the second device via the first link to switch to the second link for data reception. The first device then transmits data to the second device via the second link. When the transmission is complete, both devices switch back to using the first link to maintain their connection to each other. In some embodiments, the first device may be a Human Interface device and the second device may be a Bluetooth controller of a computing device.
