Simultaneous control information reception from source and target cells during handover

Abstract:

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a UE capability message indicating support for a dual-base station control resource allocation scheme during a make-before-break (MBB) handover procedure, the dual-base station control resource allocation scheme comprises dividing a maximum number of UE supported control channel monitoring resources between a source base station and a target base station. The UE may 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. The UE may 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.
