Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may support multi-subscriber identity module (SIM) operation in dual SIM dual active (DSDA) deployments. In some aspects, the UE may receive, via an antenna of the UE, a first signal associated with a first network subscription on a first receive path of the antenna and a second signal associated with a second network subscription on a second receive path of the antenna. The UE may determine a signal strength for each of the first signal and the second signal, determine a first gain for the first receive path and a gain for a low noise amplifier (LNA) coupled with the antenna based on the signal strength of the first signal, and determine a gain for the second receive path based on the signal strength of the second signal and the gain of the LNA.

Techniques for managing a shared low noise amplifier automatic gain control in dual sim dual active deployments

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).

Power saving by combining multiple bandwidth parts (BWPs) into a single wideband channel

Apparatuses and methods for user equipment (UE) positioning are disclosed based on a coverage enhancement level or internal signaling delay for the UE. In one embodiment, a method at a UE may include receiving a request capabilities message from a server, determining one or more capabilities of the UE, where the one or more capabilities include at least one of information for at least one internal signaling path of the UE or information for a coverage enhancement level of the UE, sending a first response message to the server, where the first response message includes the one or more capabilities of the UE, receiving a request for location measurements from the server based at least in part on the one or more capabilities of the UE, obtaining the location measurements, and sending a second response message to the server, where the second response message comprises the location measurements.

Positioning of a mobile device using an enhanced exchange of capabilities

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.

Methods and systems for a connected building emergency service

Techniques for reducing the impact of specific absorption rate (SAR) based on a transmit power back-off value in multi-antenna mobile devices are provided. An example mobile device includes a first radio frequency resource associated with first specific absorption information, a second radio frequency resource associated with second specific absorption information, and a processor configured to generate a first signal associated with a first quality of service, generate a second signal associated with a second quality of service, cause the first signal to be transmitted over one of the first radio frequency resource and the second radio frequency resource based at least in part on the first specific absorption information and the second specific absorption information, and cause the second signal to be transmitted over whichever of the first radio frequency resource and the second radio frequency resource is not used to transmit the second signal.

Antenna selection mechanism to enhance user experience

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.

Mechanism to mitigate transmitter and receiver voltage-controlled oscillator (VCO) pulling

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.
