Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may communicate using a first antenna and a second antenna. The UE may detect an event associated with a component of the UE. The UE may switch a radio frequency (RF) chain from the first antenna to a third antenna based on the detection of the event. The UE may measure, using the second antenna and the third antenna, one or more signals to obtain one or more measurement values based at least in part on switching the RF chain from the first antenna to the third antenna. The UE may transmit a communication using the second antenna or the third antenna based on the one or more measurement values. Numerous other aspects are described.

Abstract: Methods and apparatuses are presented for acquiring a wireless system by a multi-subscriber identity module (SIM) user equipment (UE). For example, an example method for acquiring a wireless system is presented that includes conducting, by a first subscription corresponding to a first SIM of the UE, a call using a shared radio resource of the UE. In addition, the example method may include predicting, upon completion of the call, a pilot timing error and a frequency error associated with a pilot signal of a network associated with a second subscription corresponding to a second SIM of the UE. In addition, the example method may include attempting to acquire the pilot signal based on the pilot timing error and the frequency error. As such, the example method may allow the multi-SIM UE to more quickly acquire a wireless system relative to legacy methods. Other aspects, embodiments, and features are also claimed and described.
