Wireless resource allocation method

Abstract

The invention relates to a method for allocating wireless resource for wireless communication system being composed of wireless communication platform, multi mobile communication users on ground, andmulti immobile communication user. (1) the minimum SINR value is calculated for communication user in all subzones using same channel in allocating scheme if wireless frequency resources, (2) repeat calculations said in (1) are done for all channels and the least value among these minimums is found out, (3) repeat calculations said in (2) are done for all schemes of wireless frequency resources and the largest value among these monimums is found out, (4) if the largest value is larger than SINA threshold set the schemes of wireless frequency resources is adopted as an optimum scheme. The invention provides new dynamic method for allocating wireless resource, improves utilization ratio of resource and increases stability of dynamic channel mode so as to be used in space communication system such as communication in stratosphere and satellite communications.

Description

1. Technical field [0001] The present invention relates to a wireless resource allocation method used in the field of information communication, and is a wireless resource especially suitable for a wireless communication system using a high-altitude wireless communication platform such as a stratospheric communication platform or a satellite communication platform and adopting a space division multiple access method Allocation method. 2. Background technology [0002] In recent years, the mobile communication market at home and abroad has continued to expand, especially after the realization of the function of mobile terminals accessing the Internet, the number of users has increased dramatically. The demand for wireless communication frequency resources is increasing. To this end, new technologies that can more effectively utilize frequency resources must be developed. [0003] Among the wireless communication systems currently in use with the feature of improving frequen...

Problems solved by technology

[0011] Problem 1: When SINR prediction channel allocation is carried out through such a distribution method, the channel allocation in one cell may have an adverse impact on the SINR performance of users who have been allocated to use the same channel in adjacent cells, which reduces the stability of the allocation method. Thus, the performance of the channel allocation method is destroyed

[0012] Problem two, in order to improve the stability of the method, it is necessary to provide the base station in a cell with the location information and channel allocation information of the users in the surrounding cells

It requires frequent communication between base stations through wireless channels or communication lines, which requires increased communication costs and time-consuming communication

[0013] To sum up, for the wireless resource allocation methods of traditional satellite mobile communication systems and terrestrial cellular mobile communication systems, the allocation of wireless channels is either too wasteful, or requires a lot of communication costs to achieve stable communication.
