Claim:
1. An apparatus of user equipment (UE) comprising transceiver circuitry and processing circuitry configured to: detect a mobility state of the UE, the mobility state being one of a plurality of different potential mobility states that comprise a high mobility state and a medium mobility state; scale at least one of an A3 offset value or a time-to-trigger (TTT) value based on the detected mobility state, wherein at least one of the TTT value is increased or the A3 offset value is decreased when the high mobility state is detected and the at least one of the TTT value or the A3 offset value is scaled for fast handover based on a predetermined condition unrelated to the mobility state, the high mobility state and fast handover defined by a Third Generation Partnership Project (3GPP) information element; compare a reference signal received power (RSRP) level of a serving cell with a RSRP level of a target cell, the predetermined condition related to a type of the serving cell and a type of the target cell, the type of the serving cell and the type of the target cell dependent on cell size, handover being initiated faster for smaller serving or target cells than for larger serving or target cells; and transmit a measurement report to an enhanced node B (eNB) of the serving cell when the RSRP level of the target cell exceeds the RSRP level of the serving cell by the A3 offset value for the TTT value.
