Abstract: A method of wireless communication includes receiving a first beam using a first antenna device during an occasion of a reference signal. The method further includes receiving a second beam using a second antenna device that is distinct from the first antenna device during the occasion of the reference signal. Receiving the first beam and the second beam includes inputting, to a modem, a representation of a combination of the first beam and the second beam. Receiving the first beam and the second beam further includes generating, by the modem based on the representation, a first signal associated with the first beam using a first parameter associated with the first antenna device and a second signal associated with the second beam using a second parameter associated with the second antenna device.

Abstract: Wireless communication system may be configured to use different frequency bands for uplink communication and downlink communication. For example, a wireless system may use multiple frequency bands for downlink with carrier aggregation, and the wireless system may use only one frequency band for uplink. Up-conversion and down-conversion between baseband signals and RF signals, using a fixed frequency local oscillator signal may cause energy leak to an adjacent frequency band during transmission of signal and may result in interferences to other radio communication devices using the adjacent bands. To limit the amount of energy that leaks out of its assigned radio frequency bands, the UE may use local oscillator signals with different frequencies for up-conversion and down-conversion and may switch the frequencies of the local oscillator signals between reception of downlink signals and transmission of uplink signals.

Abstract: An integrated circuit is disclosed that implements a delay-locked loop with differential delay lines. In an example aspect, the integrated circuit includes a first delay line, a second delay line, and control circuitry. The first and second delay lines are coupled to a reference clock source to receive a reference clock. The first delay line produces a first delayed signal that is delayed relative to the reference clock by a first delay amount. The second delay line produces a second delayed signal that is delayed relative to the reference clock by a second delay amount. The control circuitry is coupled to the first and second delay lines. The control circuitry is configured to receive the first delayed signal, to receive the second delayed signal, and to adjust the first delay amount or the second delay amount based on the first delayed signal and the second delayed signal.

Abstract: A peak detector for a power amplifier is provided that includes a threshold voltage detector configured to pulse a detection current in response to an amplified output signal from the amplifier exceeding a peak threshold. A plurality of such peak detectors may be integrated with a corresponding plurality of power amplifiers in a transmitter. Should any peak detector assert an alarm signal or more than a threshold number of alarm signals during a given period, a controller reduces a gain for the plurality of power amplifiers.

Abstract: In certain aspects, a method is provided for measuring power using a resistive element coupled between a power amplifier and an antenna. The method includes squaring a voltage from a first terminal of the resistive element to obtain a first signal, squaring a voltage from a second terminal of the resistive element to obtain a second signal, and generating a measurement signal based on a difference between the first signal and the second signal. In some implementations, the resistive element is implemented with a power switch.
