Cell measurement in physical (phy) layer and medium access control (mac) layer mobility

A method for wireless communications by a network entity, comprising:

• transmitting, to a user equipment (UE), a configuration identifying a set of cells that support physical (PHY) layer or medium access control (MAC) layer mobility signaling and a measurement configuration for the set of cells that support PHY layer or MAC layer mobility signaling;
• participating in a physical (PHY) layer or medium access control (MAC) layer measurement procedure with the UE;
• and
• transmitting, to the UE, PHY layer or MAC layer mobility signaling to update a subset of the cells that are activated for serving the UE based on participating in the PHY layer or MAC layer measurement procedure with the UE.

An apparatus for wireless communications by a user equipment (UE), comprising:

• at least one processor and a memory configured to
• receive signaling configuring the UE with a set of cells that support physical (PHY) layer or medium access control (MAC) layer mobility signaling and with a measurement configuration for the set of cells that support PHY layer or MAC layer mobility signaling;
• participate in a physical (PHY) layer or medium access control (MAC) layer measurement procedure with one or more cells in the set of cells that support PHY layer or MAC layer mobility signaling;
• receive PHY layer or MAC layer mobility signaling based on participating in the PHY layer or MAC layer measurement procedure;
• and
• update a subset of activated cells for serving the UE based on the mobility signaling.
