Antenna switching for a multiple subscriber identity module user equipment

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

• transmitting, on a first subscriber identity module (SIM) operating in a connected mode, a signal using a first antenna associated with a first antenna module of the UE;
• configuring, for a second SIM operating in an idle mode, a second antenna associated with the first antenna module for receive operations associated with an active time of the idle mode;
• switching a transmit antenna associated with the first SIM from the first antenna to a third antenna associated with a second antenna module based at least in part on configuring the second antenna for receive operations associated with the active time and based at least in part on the first antenna module being unable to support concurrent transmission and reception of signals;
• and
• transmitting, on the first SIM, a signal using the third 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:
• transmit, on a first subscriber identity module (SIM) operating in a connected mode, a signal using a first antenna associated with a first antenna module of the UE;
• configure, for a second SIM operating in an idle mode, a second antenna associated with the first antenna module for receive operations associated with an active time of the idle mode;
• switch a transmit antenna associated with the first SIM from the first antenna to a third antenna associated with a second antenna module based at least in part on configuring the second antenna for receive operations associated with the active time and based at least in part on the first antenna module being unable to support concurrent transmission and reception of signals;
• and
• transmit, on the first SIM, a signal using the third antenna.

An apparatus for wireless communication, comprising:

• means for transmitting, on a first subscriber identity module (SIM) operating in a connected mode, a signal using a first antenna associated with a first antenna module of the apparatus;
• means for configuring, for a second SIM operating in an idle mode, a second antenna associated with the first antenna module for receive operations associated with an active time of the idle mode;
• means for switching a transmit antenna associated with the first SIM from the first antenna to a third antenna associated with a second antenna module based at least in part on configuring the second antenna for receive operations associated with the active time and based at least in part on the first antenna module being unable to support concurrent transmission and reception of signals;
• and
• means for transmitting, on the first SIM, a signal using the third antenna.
