Apparatus and method for allocating resources of a virtual cell in an OFDM mobile communication system

一种正交频分复用移动通信系统中利用扇区的虚拟小区管理设备和方法，该移动通信系统包含一种具有每个都由多个扇区组成的小区的小区结构，小区通过至少一个具有正交性的子信道执行与相应小区中的移动终端的数据通信。该方法包括：由构成特定小区的扇区中的一个特定扇区和与特定扇区相邻的两个其他小区的扇区形成虚拟小区；由形成虚拟小区的三个基站，将来自虚拟小区中的移动终端的干扰测量值和信道参数估计值发送给控制虚拟小区的基站控制器，从而在虚拟小区中分配包含频率带宽、初始比特、副载波和精制比特的无线资源；将所分配的无线资源发送给三个基站，以便基站将相同的子信道分配给虚拟小区中的每个移动终端；以及通过所分配的子信道发送相同的数据。 The virtual cell management method involves allocating a wireless resource in a virtual cell based on the received interference measurement value and a channel parameter estimation value. The allocated wireless resource is transmitted to the base stations so that the base stations allocate a same sub-channel to each mobile terminal located in a virtual cell. An independent claim is also included for an apparatus for allocating resources of a virtual cell formed with a particular sector forming a particular cell and sectors of two other cells neighboring the particular sector.
