Method and apparatus for seamless handover operation in a wireless communication system

摘要

A method and apparatus for improving a mobile problem caused by a narrow handover region in a boundary region between virtual cells constructed by a plurality of small base stations are provided. A plurality of Virtual Cells (VCs) include a plurality of Distributed Base Stations (DBSs) whose VCs cooperatively communicate with each other. An Intermediate Distributed Base Station (I-DBS) is located in a region where adjacent at least two VCs among the plurality of VCs are superimposed, and belongs to a different VC according to a time division scheme.

1. An operation method of an intermediate distributed base station (I-DBS) in a wireless communication network, the method comprising:
selectively belonging to at least two adjacent virtual cells (VCs), and servicing a user equipment (UE), wherein the each of the at least two adjacent VCs is generated by a plurality of distributed base station (DBSs), wherein the plurality of DBSs are located in a cell of a macro base station, and wherein the I-DBS is located in a region where the at least two adjacent VCs are superimposed.
