    Abstract: According to one aspect, a multifunctional computing device having a wireless communications processor (e.g., cellular processor) and an application processor (e.g., general-purpose processor such as a CPU) share a storage device that is associated with or attached to the application processor. An example of such a multifunctional computing device may be a Smartphone device having a cellular phone and handheld computer functionalities. There is no specific storage device directly associated with or attached to the wireless communications processor (hereinafter simply referred to as a wireless processor). Instead, the wireless processor communicates with the application processor via a high speed communications link, such as a USB link, to access code and data stored in the storage device (e.g., flash memory device) associated with the application processor.

    Abstract: Electronic devices may be provided that contain wireless communications circuitry. The wireless communications circuitry may include radio-frequency transceiver circuitry with first and second ports that are coupled by switching circuitry to first and second antennas. A first receiver in the transceiver circuitry may be associated with the first port and a second receiver in the transceiver circuitry may be associated with the second port. An electronic device may be operated in a single receiver mode in which only one of the receivers is active to conserve power or a dual receiver mode in which signals from both antennas may be received in parallel to compare antenna performance. Based on antenna performance metrics, the electronic device may adjust the switching circuitry to ensure that an optimal antenna is being used.

    Abstract: The disclosed embodiments provide a system that uses a first antenna and a second antenna in a portable electronic device. During operation, the system receives a request to switch from the first antenna to the second antenna to transmit a signal to a cellular receiver. Next, the system loads a set of radio-frequency (RF) calibration values for the second antenna. Finally, the system performs the switch from the first antenna to the second antenna to transmit the signal, wherein the second antenna is operated using the RF calibration values after the switch.

    Abstract: Es sind hier eine Einrichtung und Verfahren für den Entwurf und das dynamische Abstimmen einer Antennenschaltung zur Nutzung über mehrere Funkfrequenzbänder bei drahtlosen Kommunikationsvorrichtungen offenbart. Eine Antenneneinrichtung umfasst eine Antennen-Abstimmsteuerung, eine Antennen-Abstimmschaltung und einen Satz von einer oder mehreren physischen Antennen. Die Antennen-Abstimmsteuerung umfasst eine Kombination aus Basisband und Frontend-Hardware und Software. Die Antennenschaltung umfasst kollektiv eine Antennen-Abstimmschaltung und den Satz der einen oder der mehreren physischen Antennen. Die Antennen-Abstimmsteuerung bestimmt basierend auf einem Satz von Funkfrequenzbändern und auf Bedingungen des Kommunikationskanals eine optimale Antennen-Abstimmkonfiguration und stellt der Antennen-Abstimmschaltung geeignete Parameter bereit. Die Antenneneinrichtung konfiguriert und optimiert die Abstimmung von der Antennenschaltung für eine zukünftige Zeitperiode, welche ein nächster Zeitschlitz sein kann. Die Antennen-Abstimmsteuerung nutzt eine Kosten-/Gewinn-Funktion, um die optimale Antennen-Abstimmkonfiguration zu bestimmen.
