Multi-subscriber identity module (sim) selection of primary sim for wakeup signal detection

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

• a first subscriber identity module (SIM);
• a second SIM;
• a memory comprising computer-executable instructions;
• and
• one or more processors configured to execute the computer-executable instructions and cause the UE to:
• select, from the first SIM and the second SIM, a primary SIM and a secondary SIM;
• decode, by the primary SIM, downlink control information (DCI);
• indicate, by the primary SIM to the secondary SIM, a wakeup grant based on the DCI;
• and
• take one or more actions, by at least one of the primary SIM or the secondary SIM, in response to the indication of the wakeup grant.

An apparatus for wireless communication at a user equipment (UE) having a first subscriber identity module (SIM) and a second SIM, comprising:

• means for selecting, from the first SIM and the second SIM, a primary SIM and a secondary SIM;
• means for decoding, by the primary SIM, downlink control information (DCI);
• means for indicating, by the primary SIM to the secondary SIM, a wakeup grant based on the DCI;
• and
• means for taking one or more actions, by at least one of the primary SIM or the secondary SIM, in response to the indication of the wakeup grant.

A non-transitory computer-readable medium having instructions to cause a user equipment (UE), having a first subscriber identity module (SIM) and a second SIM, to:

• select, from the first SIM and the second SIM, a primary SIM and a secondary SIM;
• decode, by the primary SIM, downlink control information (DCI);
• indicate, by the primary SIM to the secondary SIM, a wakeup grant based on the DCI;
• and
• take one or more actions, by at least one of the primary SIM or the secondary SIM, in response to the indication of the wakeup grant.
