Embodiment Construction

[0073] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0074] The application scenario of the embodiment of the present invention is an interference problem between a low power node (Lower power node, LPN) and a macro cell using a dynamic spectrum sharing (Dynamic spectrum sharing, DSS) technology, or an interference problem between LPN nodes. The LPN may be a Pico cell, a micro cell, a relay, a home base station HeNB (HNB), and the like. For the convenience of description, the embodiment of the present invention uses ...

Abstract

The embodiment of the invention discloses a method, a device and a system for detecting interference. Taking the implementation of the method embodiment as an example, the method comprises the following steps that: a measuring base station obtains a measuring reference mark of an interference base station, and the configuration information of the measuring reference mark; and the measuring base station detects a measuring reference mark receiving quality valve of the interference base station according to the configuration information. The embodiment of the invention provides the method and the system for the base station to detect the interference, provides long-term steady channel measurement result, and solves the problem of detecting and processing the interference of the downlink transmitting of the interference base station in common frequency, pilot frequency and disparate system on the uplink receiving of the measuring base station in the same system or disparate system on the neighboring frequency band under complex network condition, thus, the networks can be flexibly deployed and coexist with interference.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an interference detection method, device and system. Background technique [0002] In the current cellular communication system, the site of each base station is planned through the network to ensure that the interference between different base stations is within an acceptable range. With the development of communication technology, more types of spectrum are applied to cellular communication systems; therefore, it is possible to use different wireless access technologies for the same frequency, and use the same or different access technologies for adjacent frequency domains. The network layout after various types of spectrums are stolen from the cellular communication system makes the interference coexistence between base stations more complicated, so new interference detection and interference coexistence solutions are required. [0003] In addition, flexible sp...
