Problems solved by technology

[0006] This method of static frequency coordination is simple and easy, and can effectively avoid inter-cell interference. However, in some specific cases, such as when there are many users at the border of adjacent cells or there is a high peak rate demand at the border of the cell, due to the The user's main frequency resources are limited, which cannot meet the needs of carrying these higher loads; on the other hand, for those cells with small load requirements at the cell boundary, the utilization rate of the main frequency resources is not high, so that the main frequency resources are wasted

Embodiment Construction

[0078] In the following, the method of the present invention will be described in detail by taking the allocation of primary frequency resources to cell boundary users as an example in conjunction with the accompanying drawings.

[0079] Referring to Fig. 1, the inventive method comprises the steps:

[0080] Step S11 , each cell periodically reports information indicating its own border user load status or required frequency resources.

[0081] Each cell calculates the geometric factor of each user according to the Channel Quality Indicator (CQI) fed back by all users in the cell. The method for calculating the geometric factor can refer to the method given in R1-050599 and set the criterion Determine which users are central users and which are border users; next, calculate the load demand of the cell border according to the number of border users and the load of each user, and then calculate the frequency resources required by each cell border user How much is represented by...

Abstract

The invention discloses a distribution method for frequency source of wireless system which includes: every section reports the information that indicates the load state or the needed frequency source periodically; it decides the needed frequency source according to the reported information from sections, and judges the needed frequency source is bigger than the fixed frequency source which belongs to the section, if yes, the spare frequency source of adjacent sections is distributed for the section. The invention also provides the corresponding frequency source distribution device and wireless communication system. The invention can adjust the main frequency source that occupied by the boundary users according to the different load requirement of sections, it can avoid the disturbance between the section and improve the throughput of section boundary.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a method for allocating frequency resources of a wireless system, corresponding equipment and a wireless communication system. Background technique [0002] At this stage, in the research on related technologies of international wireless communication system standards, multi-carrier-based Orthogonal Frequency Division Multiplexing (OFDM) technology has received more and more attention. , LTE) standard process, it has been determined that the OFDM technology will be added to the 3GPP-EUTRA standard as an enhanced technology. In the downlink, Orthogonal Frequency Division Multiplexing Access (OFDMA) technology is adopted. The basic idea is to divide the time-frequency resources of the wireless communication system into several orthogonal narrow-band sub-channels in the frequency domain, and the high-speed data stream passes The serial / parallel conversion is transmitte...
