Abstract

Embodiments of user equipment (UE) and method for handover enhancement using reference signal received quality (RSRQ) in a wireless network are generally described herein. In some embodiments, a UE adaptively selects handover initiation parameters based, at least in part, on a velocity of the UE. The UE may determine an RSRQ of a serving cell and an RSRQ of a target cell and may transmit a measurement report to a serving eNB for handover from the serving cell to the target cell when the target cell RSRQ exceeds the serving cell RSRQ in accordance with the selected handover initiation parameters. In some of these embodiments, the handover initiation parameters may include an offset value, such as an A3offset value, and a time-to-trigger (TTT) that comprise an A3offset-TTT pair.

First claim

What is claimed is:

1. A method performed by user equipment (UE) for handover initiation, the method comprising:
selecting an A3offset-TTT pair based on a velocity of the UE, the A3offset-TTT pair comprising an A3offset value and a time-to-trigger (TTT);
determining a reference signal received quality (RSRQ) of a serving cell and an RSRQ of a target cell; and
transmitting a measurement report to an enhanced Node B (eNB) of the serving cell for handover to the target cell when…
