Techniques for enhancing user equipment performance for multiple subscriber identification module operation

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

• identifying a first set of bands associated with a first subscription;
• identifying a second set of bands associated with a second subscription different from the first subscription;
• determining that a first band from the first set of bands and a second band from the second set of bands share a set of radio frequency front-end resources;
• and
• transmitting, to a base station, a capability report excluding the first band and a third band from the first set of bands based at least in part on determining that the first band and the second band share the set of radio frequency front-end resources, the third band being associated with a secondary component carrier of a multi-carrier communications scheme.

An apparatus for wireless communication at a user equipment (UE), comprising:

• a processor;
• memory coupled with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• identify a first set of bands associated with a first subscription;
• identify a second set of bands associated with a second subscription different from the first subscription;
• determine that a first band from the first set of bands and a second band from the second set of bands share a set of radio frequency front-end resources;
• refrain from communicating on a third band from the first set of bands, the third band being associated with a secondary component carrier of a multi-carrier communications scheme, wherein refraining from communicating on the third band is based at least in part on determining that the first band and the second band share the set of radio frequency front-end resources and the third band being associated with the secondary component carrier;
• and
• communicate on a remaining set of bands from the first set of bands and the second set of bands based at least in part on refraining from communicating on the third band.
