Simultaneous control information reception from source and target cells during handover

A method for wireless communication at a source base station, comprising:

• receiving a user equipment (UE) capability message indicating support for a dual-base station control resource allocation scheme during a make-before-break (MBB) handover procedure of the UE from the source base station to a target base station, wherein the dual-base station control resource allocation scheme comprises dividing a maximum number of UE supported control channel monitoring resources between the source base station and the target base station;
• selecting, based at least in part on the dual-base station control resource allocation scheme, a first set of control channel monitoring resources for the source base station and a second set of control channel monitoring resources for the target base station;
• and
• transmitting, during the MBB handover procedure, source base station control information from the source base station during the first set of control channel monitoring resources while the target base station transmits target base station control information during the second set of control channel monitoring resources.

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:
• transmit a UE capability message indicating support for a dual-base station control resource allocation scheme during a make-before-break (MBB) handover procedure from a source base station to a target base station, wherein the dual-base station control resource allocation scheme comprises dividing a maximum number of UE supported control channel monitoring resources between the source base station and the target base station;
• identify, based at least in part on the dual-base station control resource allocation scheme, a first set of control channel monitoring resources for the source base station and a second set of control channel monitoring resources for the target base station;
• and
• receive, during the MBB handover procedure, control information from the source base station during the first set of control channel monitoring resources and from the target base station during the second set of control channel monitoring resources.
