Abstract: Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive a plurality of resource block allocations corresponding to a plurality of carriers. The user equipment may identify a carrier, of the plurality of carriers, to be used for communication of at least one high priority communication based at least in part on a comparison of a plurality of frequencies corresponding to the plurality of resource block allocations. The user equipment may communicate the at least one high priority communication using the identified carrier. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide methods and apparatus for wireless communication. One example apparatus generally includes a first transceiver configured to transmit and receive signals in a first frequency band and a second transceiver configured to transmit and receive signals in a second frequency band. The apparatus may also include a processing system coupled to the first transceiver and the second transceiver. The processing system may be configured to dynamically assign transmission operations or reception operations of a signal in the first frequency band to the second transceiver.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may operate in a dual-connectivity (DC) configuration, and may measure signals from more than one radio access technology (RAT). The UE may receive a first signal power for a first RAT and a second signal power for a second RAT. The UE may determine a common gain state for the first RAT and the second RAT based on the first signal power and the second signal power. The UE may then apply the common gain state to a first receiver chain within the UE for the first RAT and to a second receiver chain within the UE for the second RAT, where the first receiver chain and the second receiver chain share at least one shared low noise amplifier (LNA).

Abstract: Techniques for calibrating a crystal oscillator of a wireless device are provided. A method according to these techniques includes operating a transmit path of the wireless device at a first carrier frequency, configuring a receive path of the wireless device to receive at a second carrier frequency, the second carrier frequency being offset from the first carrier frequency by a first frequency offset, transmitting a tone using the transmit path at a frequency that is offset from the first carrier frequency by a second frequency offset that is different than the first frequency offset, receiving a second tone via the receive path, and determining the oscillator error based on the second tone.

Abstract: A method of wireless communications by a user equipment (UE) includes detecting, in response to a bandwidth part (BWP) switch, a first BWP of a first carrier aggregation signal and a second BWP of a second carrier aggregation signal. The first BWP of the first carrier aggregation signal and the second BWP of the second carrier aggregation signal are each within a predetermined frequency range of each other. The method also includes tuning a radio frequency (RF) channel to a center of a wideband channel including the first BWP and the second BWP. The method further includes processing the wideband channel including both the first BWP of the first carrier aggregation signal and the second BWP of the second carrier aggregation signal with a single phase locked loop (PLL).

Abstract: A method of supporting emergency services at a server includes: detecting an emergency condition; sending a first notification of the emergency condition to at least one mobile device; determining information for the at least one mobile device; determining a requirement to notify an emergency service provider based, at least in part, on the information for the at least one mobile device; and sending a second notification of the emergency condition to the emergency service provider in response to the requirement to notify the emergency service provider being determined.

Abstract: A user equipment (UE) determines availability of one or more of the radio frequency (RF) resources (e.g., shared power tracking mode devices) and dynamically assigns (during simultaneous active operation or transmission by the two or more transmit chains) one or more RF resources to selected one or more active transmit chains in the user equipment. In one instance, the UE selectively assigns the shared power tracking mode device(s) to the active transmit chain(s) based on the determined availability.
