The system also comprises a controller adapted to cause configuration of the respective chip- associated frequency generator of at least one of the transceiver chips, wherein the configuration comprises dynamically setting the respective conversion frequency. Typically, the respective conversion frequencies are different for at least two of the transceiver chips. For example, the respective conversion frequencies may be two different frequencies for carrier aggregation and/or dual connectivity. In some embodiments, the controller comprises at least one respective piece of circuitry comprised on at least one of the transceiver chips. The respective piece of circuitry is adapted to cause configuration of the respective chip-associated frequency generator of at least the transceiver chip on which it is comprised. In some embodiments, the controller comprises a single piece of circuitry separate from the transceiver chips. The single piece of circuitry is adapted to cause configuration of the respective chip-associated frequency generator of two or more of the transceiver chips.

摘要： A portable communication device provides improved converged operations through the use of a programmable logic array operating as a coexistence module (CEM) interoperating with different processors, different modems, and an attenuation switch. Interference during converged operation is detected, analyzed, and applicable mitigation is applied, thereby enabling converged communications to be established in a mitigated mode until the interference has been removed.

摘要： According to one embodiment, a millimeter-wave (mm-wave) frontend integrated circuit includes an array of mm-wave transceivers, where each of the mm-wave transceivers transmits and receives coherent mm-wave signals with variable amplitudes and phase shifts. The mm-wave frontend IC chip further includes a wideband frequency synthesizer coupled to the mm-wave transceivers. The full-based or wideband frequency synthesizer generates and provides a local oscillator (LO) signal to each of the mm-wave transceivers to enable the mm-wave transceiver to mix, modulate, and/or demodulate mm-wave signals. The array of mm-wave wideband transceivers and the wideband frequency synthesizer may be implemented within a single IC chip as a single mm-wave frontend IC chip or package.

摘要： The solution presented herein is directed to communication devices having a plurality of circuits that may be configured into a plurality of different receiver configurations (or classes), where each receiver configuration uses a different technique for processing a received signal. The solution presented herein enables the communication device to select at least one receiver configuration/class for processing received signals. To that end, a performance metric is determined for each receiver configuration in a subset of receiver configurations using at least one of a received signal, a signal strength determined for the corresponding receiver configuration, and an interference level determined for the corresponding receiver configuration. At least one of the receiver configurations in the subset is selected responsive to the determined performance metrics, and in some cases also in response to a scheduled amount of data.

摘要： Aspects of the disclosure are directed to interference cancellation and wireless communication. A method of performing analog interference cancellation in a wireless communications device having a transmitter and a receiver includes receiving a reference signal representative of an interfering signal transmitted by the transmitter, selecting a first target interference type from one of a plurality of interference types affecting a an RF signal received by the receiver, configuring a first filter of an interference cancellation circuit using a coefficient computed based on the first target interference type, and cancelling interference in the RF signal using an output of the first filter. Coefficient computation may be performed in a switched manner between analog and digital domain, simultaneously in multiple domains, or in a cascaded manner that provides digital interference cancellation.
