Aspects of the disclosure relate to radar-based signaling for detecting, measuring, and/or characterizing a target object. An electronic device may transmit a plurality of detection signals and receive a plurality of reflection signals reflected from the target object. The electronic device then processes the plurality of reflection signals to extract one or more parameters of the target object. Based on the reflection signals, the device can measure and/or characterize the target object, e.g., to obtain a heart rate and/or breathing rate. In other examples, the device may determine whether the reflection signals indicate human vital signs, such as a heart rate or breathing. The electronic device may then adjust at least one transmission parameter based on whether human vital signs are detected at the target object, and transmit the adjusted signal using the transmission parameter. Other aspects, embodiments, and features are also claimed and described.

Wireless communication with enhanced maximum permissible exposure (MPE) compliance based on vital signs detection

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

Aspects of the disclosure relate to classifying a target object. An electronic device may transmit a detection signal and receive a reflection signal reflected from the target object. The electronic device then determines, based on one or more features of the reflection signal, a category of the target object and adjusts at least one transmission parameter based on the category. The electronic device then transmits an adjust signal using the transmission parameter. Other aspects, embodiments, and features are also claimed and described.

Wireless communication with enhanced maximum permissible exposure (MPE) compliance

An apparatus includes a first amplifier stage configured to amplify a first carrier signal. The apparatus includes a second amplifier stage configured to amplify a second carrier signal. A resistive-capacitive (RC) network is coupled to the first amplifier stage and to the second amplifier stage. The RC network includes a resistive element coupled to a capacitive element.

Multi-stage amplifier with RC network

The various embodiments include a dual-SIM-dual-active (DSDA) device and methods for implementing robust receive (Rx) processing to resolve radio frequency coexistence interference between two subscriptions operating on the DSDA device. The DSDA device may detect when a subscription (the 'aggressor') de-senses the other subscription (the 'victim') as a result of the aggressor's transmissions, and in response, implement robust Rx processing to mitigate the effects of de-sense on the victim while causing minimal impact to the aggressor.
