Techniques for antenna switching management in a multiple subscriber identity module mode

A user equipment (UE) for wireless communication, comprising:

• one or more memories;
• and
• one or more processors, coupled to the one or more memories, configured to:
• establish, using a first frequency band, a first communication connection on a first subscriber identity module (SIM);
• establish, using a second frequency band, a second communication connection on a second SIM in a multi-SIM dual receive mode that includes the first SIM and the second SIM having concurrent activity;
• switch from a first antenna to a second antenna for the first SIM in accordance with an antenna switching capability that is based at least in part on whether the first communication connection and the second communication connection are time division duplex (TDD) synchronized;
• and
• transmit one or more communications associated with the first SIM using the second antenna.

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:
• establish, using a first frequency band, a first communication connection on a first subscriber identity module (SIM);
• establish, using a second frequency band, a second communication connection on a second SIM in a multi-SIM dual receive mode that includes the first SIM and the second SIM having concurrent activity;
• switch from a first antenna to a second antenna for the first SIM in accordance with an antenna switching capability that is based at least in part on whether the first communication connection and the second communication connection are time division duplex (TDD) synchronized;
• and
• transmit one or more communications associated with the first SIM using the second antenna.

An apparatus for wireless communication, comprising:

• means for establishing, using a first frequency band, a first communication connection on a first subscriber identity module (SIM);
• means for establishing, using a second frequency band, a second communication connection on a second SIM in a multi-SIM dual receive mode that includes the first SIM and the second SIM having concurrent activity;
• means for switching from a first antenna to a second antenna for the first SIM in accordance with an antenna switching capability that is based at least in part on whether the first communication connection and the second communication connection are time division duplex (TDD) synchronized;
• and
• means for transmitting one or more communications associated with the first SIM using the second antenna.
