Description

A kind of method and apparatus for configuring frequency range

Technical field

The present invention relates to wireless communication technology field, more particularly to a kind of method and apparatus for configuring frequency range.

Background technology

LTE (Long Term Evolution, Long Term Evolution) system descending uses OFDMA (Orthogonal Frequency Division Multiple Access, OFDM) technology is up to use SC- as transmission means FDMA (Single-carrier Frequency Division Multiple Access, single-carrier frequency division multiple access) technology is made For transmission means.Because the multiple access technology that uplink and downlink use make use of the orthogonality between frequency so that in theory, this It is non-interfering between community user.The interference that all users are subject in this cell, it is mainly derived from other and uses same frequency The edge customer of the neighbor cell of rate resource, particularly this cell, the co-channel interference by neighbor cell are especially serious.Due to this The edge customer of cell is reduced the call performance of this Cell Edge User, entered by the serious co-channel interference of neighbor cell And reduce the handling capacity of whole system.

In order to improve the call performance of LTE system Cell Edge User, and then improve the handling capacity of whole system, this area Technical staff propose many solutions.Such as：ICIC (Inter Cell Interference Coordination, Inter-Cell Interference Coordination), it is the interference coordination technique that a kind of frequency range used in edge customer by cell realizes orthogonalization, passes through Using ICIC interference coordination techniques, interference coordination is carried out.Using ICIC interference coordination techniques under simple network environment, carry out During interference coordination, fixed is divided into three sections by whole frequency range, using one section in three sections as Main subcarriers (primary Subcarriers), allow to launch higher power, the auxiliary subcarrier (secondary of remaining two sections of conduct on Main subcarriers Subcarriers), only allow to launch relatively low power on auxiliary subcarrier；For each cell configuration frequency range when, i.e., to be every Individual cell determine Main subcarriers position and auxiliary subcarrier position when so that shared by the Main subcarriers of two adjacent cells Frequency range it is mutually orthogonal, the frequency range of auxiliary subcarrier can overlap, and Main subcarriers can use from anywhere in cell, and auxiliary son Carrier wave the heart can only then be used in the cell, and the co-channel interference of the neighbor cell suffered by Cell Edge User is reduced with this, is entered And improve the call performance of LTE system Cell Edge User, improve the handling capacity of whole system.As shown in figure 1, done using ICIC Three cell configuration frequency ranges that coordination technique is LTE system are disturbed, as can be known from Fig. 1, the Main subcarriers of cell 1 are No. 0 frequency range, Subcarrier supplemented by No. 1 frequency range and No. 2 frequency range, and the power of No. 0 frequency range is more than the power of No. 1 frequency range, also greater than the 2nd The power of number frequency range；The Main subcarriers of cell 2 are No. 1 frequency range, subcarrier supplemented by No. 0 frequency range and No. 2 frequency range, and the 1st The power of number frequency range is more than the power of No. 0 frequency range, also greater than the power of No. 2 frequency range；The Main subcarriers of cell 3 are No. 2 Subcarrier supplemented by frequency range, No. 0 frequency range and No. 1 frequency range, and the power of No. 2 frequency range is more than the power of No. 0 frequency range, also greatly In the power of No. 1 frequency range.

But because what the above method was fixed is divided into the frequency range of LTE system three sections, and determining to lead for each cell Behind the position of subcarrier, it is impossible to change the position of Main subcarriers, for intensive complicated identical networking environment, this method is simultaneously It cannot be guaranteed that the frequency range shared by the Main subcarriers of all neighbor cells is mutually orthogonal.

In summary, the current method that frequency range is configured for neighbor cell, it is impossible to ensure that the boss of all neighbor cells carries Frequency range shared by ripple is mutually orthogonal, reduces the call performance of this Cell Edge User, and then reduces gulping down for whole system The amount of telling.

The content of the invention

The present invention provides a kind of method and apparatus for configuring frequency range, to solve to be neighbor cell present in prior art A method for configuring frequency range, it is impossible to ensure that the frequency range shared by the Main subcarriers of all neighbor cells is mutually orthogonal, reduce small The call performance of area edge user, and then the problem of reduce the handling capacity of whole system.

A kind of method for configuring frequency range provided in an embodiment of the present invention includes：

The Neighboring Cell List that cell according to receiving reports, the cell of all reporting neighboring cell lists is divided at least one Mutual adjacent area set, wherein any two cell in mutually adjacent area set adjacent area each other；

Frequency range numbering corresponding to the cell of unallocated frequency range numbering at least one mutually adjacent area set is determined, wherein, each Mutually the frequency range numbering of any two cell in the set of adjacent area is different, and the frequency range is numbered can according to frequency range hop count for mark The frequency range of distribution divides equally obtained frequency sub-band；

For a cell, according to the frequency range of determination numbering and the frequency range hop count, issued to the cell It can determine the information of Main subcarriers position.

Because the embodiment of the present invention is the cell distribution frequency range numbering in the mutual adjacent area set marked off, and each mutual adjacent area The frequency range numbering of any two cell in set is different, so that frequency of any two cell during mutually adjacent area is gathered according to determination The Main subcarriers position that segment number determines with frequency range hop count is different, so as to ensure that shared by the Main subcarriers of all neighbor cells Frequency range it is mutually orthogonal, improve the call performance of this Cell Edge User, and then improve the handling capacity of whole system.

It is preferred that Main subcarriers position is issued to the cell according to the frequency range of determination numbering and the frequency range hop count Information, including：

The Main subcarriers position of the cell is determined according to frequency range numbering and the frequency range hop count, the boss is carried The cell is handed down to as can determine the information of Main subcarriers position in ripple position；Or

Using frequency range numbering and the frequency range hop count as can determine the information of Main subcarriers position, and it is handed down to institute State cell.

It is preferred that described determine that frequency range corresponding to the cell of unallocated frequency range numbering is compiled at least one mutually adjacent area set Number, including：
