A user equipment (UE) is configured to perform layer 1 (L1), layer 2 (L2) and layer (3) mobility operations. The UE determines a measurement gap sharing scheme for layer 1 (L1)/layer 2 (L2) based mobility and layer 3 (L3) based mobility, determines a measurement gap pattern, wherein at least one measurement gap includes L1/L2 measurement occasions and L3 measurement occasions and collects measurement data during the at least one measurement gap in accordance with the measurement gap sharing scheme.
