Optimized multiple subscriber identity module mode in high mobility environments

A method of wireless communication performed by a user equipment (UE), comprising:

• detecting, by a first subscriber identity module (SIM) operating in a connected mode, that the UE is operating in a high mobility environment;
• transmitting, by the first SIM and to a second SIM operating in an idle mode, an indication that the UE is operating in the high mobility environment and an indication of a first frequency error estimation associated with the first SIM;
• and
• operating, by the second SIM, in a high mobility mode using a second frequency error estimation that is based at least in part on the first frequency error estimation associated with the first SIM.

A non-transitory computer-readable medium storing a set of instructions for wireless communication, the set of instructions comprising:

• one or more instructions that, when executed by one or more processors of a user equipment (UE), cause the UE to:
• detect, by a first subscriber identity module (SIM) operating in a connected mode, that the UE is operating in a high mobility environment;
• transmit, by the first SIM and to a second SIM operating in an idle mode, an indication that the UE is operating in the high mobility environment and an indication of a first frequency error estimation associated with the first SIM;
• and
• operate, by the second SIM, in a high mobility mode using a second frequency error estimation that is based at least in part on the first frequency error estimation associated with the first SIM.

An apparatus for wireless communication, comprising:

• means for detecting, by a first subscriber identity module (SIM) operating in a connected mode, that the apparatus is operating in a high mobility environment;
• means for transmitting, by the first SIM and to a second SIM operating in an idle mode, an indication that the apparatus is operating in the high mobility environment and an indication of a first frequency error estimation associated with the first SIM;
• and
• means for operating, by the second SIM, in a high mobility mode using a second frequency error estimation that is based at least in part on the first frequency error estimation associated with the first SIM.
