Method, system and device for uplink interference source detection

Abstract

The invention discloses a method used for detecting uplink interference source, comprising the steps as follows: a base station receives a downlink interference detection result reported by a terminal; the downlink interference detection result is the detection result of the downlink interference source signal of the neighbor base station detected by the terminal; the base station determines the terminal as the uplink interference source of the neighbor base station according to the downlink interference detection result. The embodiment of the invention needs not to transmit uplink interference signal by dividing additional uplink interference transmission interval correspondingly to the uplink interference source detection, thus saving the air interface resource, improving the air interface efficiency and reducing the realization complexity of the base station and the terminal at the same time.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, system and device for detecting an uplink interference source. Background technique [0002] With the development of wireless communication technology, the demand for wireless spectrum becomes stronger and stronger. However, according to the frequency division of ITU (International Telecommunication Union, International Telecommunication Union) radio regulations, the range of radio frequencies that can be used by various wireless services is 9 KHz to 275 GHz. Due to the limitation of wireless spectrum resources, wireless spectrum resources become an increasingly scarce resource. In order to better improve the utilization rate of the wireless spectrum, especially the licensed frequency band, cognitive radio technology has been proposed in recent years. Wireless devices that support cognitive radio technology must dynamically sense the surrounding environm...

Problems solved by technology

However, this method also needs to reserve air interface resources to send signals for uplink interference detection, so certain air interface resources are occupied

Base stations and terminals need to perform corresponding signal transmission and detection for uplink interference detection, which also increases the complexity of base stations and terminals

In addition, the base station of this method first needs to know which system terminal is sending the interference signal in a specific time slot, otherwise it cannot find the neighbor base station, and its application has certain limitations

[0006] Therefore, the method for detecting uplink interference sources in the prior art needs to use additional air interface resources to transmit signals for uplink interference source detection, which causes a certain waste of air interface resources, and the base station and terminal also need to increase a certain amount of uplink signals Functions such as transmission and detection increase the complexity of base stations and terminals
