    Abstract: Mechanisms are provided for a user equipment (UE) to determine to use a shared resource such as an antenna to access a land based wireless communication system or a satellite communication system. The UE can provide a first priority indication to indicate whether to access the land based wireless communication system based on one or more wireless link metrics of the land based wireless communication system or one or more application metrics for applications using the land based wireless communication system; and provide a second priority indication to indicate whether to access the satellite wireless communication system based on one or more service metrics provided by the satellite wireless communication system. The UE can determine to use the shared resources to access the land based wireless communication system or the satellite communication system based on the first priority indication and the second priority indication.

    Abstract: An electronic device may include first and second phased antenna arrays that convey radio-frequency signals at frequencies greater than 10 GHz. The second array may have fewer antennas than the first array. Control circuitry may control the first and second arrays in a diversity mode and in a simultaneous array mode. In the diversity mode, the first array may form a first signal beam while the second array is inactive. When the first array is blocked by an object or otherwise exhibits unsatisfactory performance, the second array may form a second signal beam while the first array is inactive. In the simultaneous mode, the first and second arrays may form a combined array that produces a third signal beam. The combined array may maximize gain. Hierarchical beam searching operations may be performed. The arrays may be distributed across one or more modules.

    Abstract: An electronic device receives an indication of a number of physical resource blocks and subcarrier spacing of at least a portion of a transmission channel and determines a dynamic transmission bandwidth, or receives an indication of a modulation coding scheme of the transmission channel and determines a modulation order. The electronic device transmits, using a transmitter, a signal over at least the portion of the transmission channel based on the dynamic transmission bandwidth being less than or equal to a threshold bandwidth, or the modulation order not corresponding to an additional power backoff, using a first power based on a maximum output power capacity of the electronic device and a maximum power reduction. Otherwise, the electronic device transmits the signal over at least the portion of the transmission channel at a second power based on the maximum output power capacity, the maximum power reduction and the additional power backoff.

    Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for storing a codebook in an integrated circuit. One of the methods includes storing, for an integrated circuit that comprises a memory, first data for a codebook in the memory; determining second data for the codebook using the first data; and sending, over a bus, the second data for the codebook to an antenna module separate from the integrated circuit.
