1. A user equipment (UE) for wireless communication, comprising:
a memory; and
one or more processors, coupled to the memory, configured to:
establish a first communication associated with a first priority, wherein the first communication is associated with a first subscriber in a connected mode, the first communication is ongoing;
establish a second communication associated with a second priority, wherein the second communication is associated with a second subscriber in the connected mode, the first priority is higher than the second priority;
identify one or more components shared between the first communication and the second communication, wherein the one or more components are included in a radio frequency front-end (RFFE) of the UE, are switchable between the first subscriber and the second subscriber, and include at least one of:
a transmit/receive (TRX) switch,
a low noise amplifier (LNA), or
a cross-switch; and
perform at least one of the first communication or the second communication using a configuration to prevent damage to the one or more components of the UE based at least in part on the one or more components being shared between the first communication and the second communication, wherein perform at least one of the first communication or the second communication using the configuration to prevent damage to the one or more components comprises:
prevent the TRX switch from switching to a state associated with the second communication.
