In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The method may be performed by a UE. In certain configurations, the UE performs a procedure resulting in a status change of a first pre-configured measurement gap (pre-MG) of a pre-MG activation procedure. The UE determines whether the pre-MG activation procedure collides with or is overlapped with an overlapping gap. In response to determining that the pre-MG activation procedure collides with or is overlapped with the overlapping gap, the UE configures a pre-MG activation delay for the first pre-MG after an end of the overlapping gap, and performs the pre-MG activation procedure in the first pre-MG after the pre-MG activation delay.
