Carrier aggregation for low-latency handover

A method of wireless communication performed by a base station, comprising:

• receiving information identifying a band combination capability for performing a handover of a user equipment (UE) using carrier aggregation,
• wherein the band combination capability identifies a plurality of bands or carriers;
• and
• transmitting handover information for the handover of the UE based at least in part on the information identifying the band combination capability,
• wherein at least one first band or carrier, of the plurality of bands or carriers, is used for a source base station of the handover and at least one second band or carrier, of the plurality of bands or carriers, is used for a target base station of the handover, and wherein the handover information identifies the at least one first band or carrier and the at least one second band or carrier.

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

• a memory;
• and
• one or more processors operatively coupled to the memory, the memory and the one or more processors configured to:
• provide information identifying a band combination capability for performing a handover of the UE using carrier aggregation,
• wherein the band combination capability identifies a plurality of bands or carriers;
• and
• perform the handover based at least in part on the information identifying the band combination capability,
• wherein at least one first band or carrier, of the plurality of bands or carriers, is used for a source base station of the handover and at least one second band or carrier, of the plurality of bands or carriers, is used for a target base station of the handover.
