Embodiment Construction

[0039] Taking the WiAX system as an example, the technical solution of the present invention will be further described in detail in conjunction with the accompanying drawings. However, the present invention is not limited to the application in the WiMAX system, but can be applied to various communication systems using partial frequency reuse technology.

[0040] The initial configuration of resource allocation areas in this embodiment is to divide the entire system frequency band resources into three resource allocation areas F1, F2, and F3. The central users of the three sectors can use the resources in two of the resource allocation areas, and the edge Users can only use resources in one of the resource allocation areas, and resource allocation areas configured by different sectors for edge users do not overlap each other in frequency to avoid interference. Of course, the present invention is not limited to this initial configuration. if available figure 1 In the existing ...

Abstract

The invention discloses a resource allocation method with partial frequency multiplexing, which comprises the following steps of: dividing users of accessed user terminals in a cell into central users and edge users by a base station; and carrying out self-adaptive adjustment on resource allocation regions allocated to the central users and the edge users in a sector by the base station, for each sector in the cell, according to quantity information of the central users and the edge users in the sector, and notifying the user terminals in the sector. Therefore, the resource allocation method can allocate the resources more reliably and avoid interference as much as possible.

Description

technical field [0001] The present invention relates to a wireless communication system, and more particularly, to a resource allocation method when fractional frequency reuse (FFR) is used in the wireless communication system. Background technique [0002] WiMAX supports frequency reuse with a factor of 1 (all cells / sectors use the same frequency). However, due to the influence of co-channel interference, the communication quality of users at the edge of the cell will be significantly reduced. However, in OFDMA-based WiMAX, users using bandwidth resources based on sub-channels can only occupy a part of the entire bandwidth. In this way, the problem of co-channel interference at the edge of the cell can be solved by reasonably configuring the allocation of sub-channels during scheduling. Use traditional spectrum planning methods. Using the fractional frequency reuse (FFR) technology, different frequency reuse coefficients can be used according to the channel conditions and...
