Disturbance allocation method, system, database and reconfiguration management node

Abstract

The invention discloses an interference allocation method, comprising: a reconfiguration management node of a secondary system acquires or receives idle spectrum resource information, and the total interference value information that the secondary system is allowed to generate on idle spectrum resources; The reconfiguration management node calculates transmit power for the secondary user equipment subordinate to the reconfiguration management node according to the total interference value information that the secondary system is allowed to generate. The invention also discloses an interference distribution system, a reconfiguration management node and a database at the same time. The invention can realize the secondary system to flexibly configure the transmission power between devices within the range of the allocated total interference quota, and the configuration time delay is controllable.

Description

technical field

[0001] The present invention relates to cognitive radio technology in the field of wireless communication, in particular to a secondary system-based interference allocation method, system, database and reconfiguration management node. Background technique

[0002] With the continuous advancement of radio technology, a large number of various radio services have emerged, but the spectrum resources that radio services rely on are limited. Faced with the continuous increase in people's demand for bandwidth, spectrum resources are extremely tense. However, in the traditional fixed spectrum allocation mode, the utilization rate of spectrum resources is not high. In a sense, it is this spectrum allocation system that is fixedly allocated to the licensed system that has caused the extremely tight situation of spectrum resources. The cognitive radio technology breaks the fixed spectrum allocation system in the traditional sense, and dynamically allocates the spectrum...
