Title
(EN) Space-time spectrum sharing method and system based on regional division
(ZH) 一种基于区域划分的空时频谱共享方法和系统
Abstract
(EN) The invention discloses a space-time spectrum sharing method and a system based on regional division. Master user communication parameters and secondary user communication parameters respectively sent by master users and secondary users are received; Boundary calculation of a spectrum sharing area is conducted by the combination of the master user communication parameters and the secondary user communication parameters, and the spectrum sharing area is divided into five areas; Each secondary user belongs to which area is judged according to the secondary user parameters, and a corresponding sharing way is adopted to conduct the space-time spectrum sharing according to the judged results. According to the space-time spectrum sharing method and the system based on the regional division, spectrum opportunities on a time domain are fully used in a cognitive wireless network., the space-domain spectrum sharing and the time-domain spectrum sharing are organically combined, and thereby the spectrum utilization efficiency is further improved, boundaries of each area in the spectrum sharing area are calculated, and the actual operation value is strong.

本发明公开了一种基于区域划分的空时频谱共享方法和系统,通过接收主用户和认知用户分别发送的主用户通信参数和认知用户通信参数;结合主用户通信参数和认知用户通信参数进行频谱共享区域的边界计算,将频谱共享区域划分为五个区域;根据认知用户通信参数判定每个认知用户属于频谱共享区域中的哪一区域,并根据判定结果采用相应的共享方式进行空时频谱的共享。本发明在认知无线网络中充分利用时域上的频谱机会,将空域频谱共享与时域频谱共享有机结合,从而进一步提升频谱利用效率,对频谱共享区域中的每个区域的边界进行计算方法,具有很强的实际操作价值。
