Group based cell configuration for inter-cell mobility

An apparatus for wireless communications at a network entity, 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, to a user equipment (UE), first control signaling identifying, of a plurality of cell groups configured at the UE, an inter-cell mobility configuration for a set of one or more cell groups, wherein each cell group of the plurality of cell groups comprises a primary cell and zero or more secondary cells;
• receive, from the UE, a measurement report for each cell group of the set of one or more cell groups for inter-cell mobility;
• and
• transmit, at least in part in response to receiving the measurement report, second control signaling activating or deactivating a primary cell group for inter-cell mobility from one or more cell groups of the set of one or more cell groups.

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

• receiving first control signaling identifying, of a plurality of cell groups configured at the UE, an inter-cell mobility configuration for a set of one or more cell groups for use at the UE, wherein each cell group of the plurality of cell groups comprises a primary cell and zero or more secondary cells;
• transmitting a measurement report for each cell group of the set of one or more cell groups for inter-cell mobility;
• and
• receiving, at least in part in response to transmitting the measurement report, second control signaling activating or deactivating a primary cell group for inter-cell mobility from one or more cell groups of the set of one or more cell groups.
