Abstract: In an example method, a user equipment (UE) of a wireless network determines data for transmission between the UE and a base station (BS) of the wireless network; determines a context of the transmission of the data between the UE and the BS; selects, based on the context, one or more antenna elements of an antenna array of the UE; and forms one or more wireless beams using the one or more selected antenna elements. Further, the UE (i) transmits at least a first portion of the data to the BS using the one or more wireless beams, and/or (ii) receives at least a second portion of the data from the BS using the one or more wireless beams.

Abstract: A method includes receiving an indication to transmit a first set of signals using a first standard (e.g., Long Term Evolution) via a first set of antennas of a radio frequency device and a second set of signals using a second standard (e.g., New Radio) via a second set of antennas. The method also includes transmitting the first set of signals via the first set of antennas using a first power based on positions of the first set and second set of antennas, exposure conditions of the first set and the second set of signals on a user, and/or priorities of the first and the second set of signals. Moreover, the method includes transmitting the second set of signals via the second set of antennas using a second power based on the positions of the antennas, the exposure conditions of the signals on the user, and/or priorities of the signals.

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: The exemplary embodiments relate to a user equipment configured to connect to a network that supports simultaneous connection to a first radio access technology (RAT) and a second RAT. The UE may receive coverage information associated with the first RAT and a cell of the second RAT, receive an indication of the current UE location relative to the cell of the second RAT and determine whether the first RAT is available for camping based on the coverage information and the indication of the current UE location relative to the cell of the second RAT.

Abstract: Apparatuses, systems, and methods for high data mode operation in cellular networks. A UE may determine, for an interface to a high-speed cellular network, a categorization from a plurality of categorizations, determine availability of the high-speed cellular network, and select, based at least in part on the categorization and availability of the high-speed cellular network, the interface for a data connection to the high-speed cellular network. The categorization may be one of expensive or not expensive and/or one of a first level associated with a higher compression codec rate or a second level associated with a lower compression codec rate. The UE may receive, from one of the a low-speed cellular network or the high-speed cellular network, carrier plan information for a cellular data service carrier and analyze the carrier plan information to determine desirability of a switch, e.g., from the low-speed cellular network to the high-speed cellular network.

Abstract: This disclosure relates to dynamic baseband management for a wireless device. The wireless device may be an accessory device. The accessory device may determine whether it has a short-range wireless communication link with a companion device. The accessory device may determine one or more proximity metrics relating to the companion device. The accessory device may further determine one or more metrics associated with user settings, user activity and/or application activity at the wireless device. The wireless device may select a (e.g., full, limited, or off) baseband operating mode based on any or all of these considerations.

Abstract: Some embodiments relate to a user equipment device (UE), and associated methods for enabling the UE to estimate velocity of the UE based on cellular parameters. In some embodiments, a first velocity of a UE may be estimated based on a first set of parameters associated with one or more cellular based metrics. Doppler measurements may be performed in response to the first velocity exceeding a velocity threshold for at least a time period. In some embodiments, performing (or conducting) the Doppler measurements may be triggered by (e.g., in response to) the first velocity exceeding the velocity threshold for at least the first time period and receiving an indication from a motion processor of the UE that the UE is in a non-static state. In addition, a second velocity of the UE may be estimated based on the first set of parameters and the Doppler measurements.
