Problems solved by technology

However, frequent handovers occur between virtual cells
Since the border area between virtual cells is a border between small base stations with small coverage, the handover range is narrow and there is a possibility that handover is carried out at a low received signal level

Abstract

Provided are a method and apparatus for improving mobility problems caused by a narrow handover range in a boundary area between virtual cells constructed by a plurality of small base stations. A virtual cell (VC) includes a plurality of distributed base stations (DBS), and the DBSs of the VC cooperatively communicate with each other. The Intermediate Distributed Base Station (I-DBS) is located in a region where at least two adjacent VCs overlap among multiple VCs, and belongs to different VCs according to a time division scheme.

Description

technical field [0001] The present disclosure relates to a next-generation mobile communication technology for improving radio capacity and simultaneously enabling seamless and stable mobility support in a wireless communication system. Background technique [0002] The goal of a communication system is to send large amounts of data with a low error rate. In order to achieve this goal, the communication system should have a high system capacity. In recent years, femtocell technology, which reduces the cell radius to reduce the interval between users and radio access units (RAUs) and thereby improves performance, has been proposed for communication through cooperative transmission of neighboring base stations. Coordinated Multipoint (CoMP) technology, Virtual Cell Network (VCN) technology, etc. to improve performance of cell border user equipment. [0003] A VCN represents a network topology that adaptively forms virtual cells and provides services in order to maximize freq...
