Embodiment Construction

[0056] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, and are not intended to limit the protection scope of the present invention.

[0057] see figure 1 , figure 1 It is a flowchart of a method for notifying interference information according to an embodiment of the present invention. The method for notifying interference information in this embodiment includes the following steps:

[0058] Step S110: Obtain the start position and length value of the interference resource block currently communicating with the user terminal.

[0059] In this step, the interfering resource block refers to a resource block with narrowband interference. When there is narrowband interference in the system ...

Abstract

The present invention relates to the technical field of wireless communication, in particular to a method and system for notifying interference information. This solution obtains the initial position and length value of the interference resource block currently communicating with the user terminal; obtains the interference information notification information according to the initial position and length value of the interference resource block, wherein at least two bits in the interference information notification information The bit records the starting position of the interference resource block, and at least two bits record the length value of the interference resource block; the interference information notification information is sent to the user terminal for analysis, so that the user terminal obtains the current interference information. In the above solution, the interference information notification information saves the description of resource blocks without narrowband interference, reduces error information, and makes the interference of resource blocks within the system bandwidth be more accurately notified to the user terminal.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method and system for notifying interference information. Background technique [0002] In the field of private communication, long-term evolution (Long Term Evolution, LTE) systems often have strong narrowband interference, which is usually narrowband interference from different systems, such as malicious interference. In the case of strong narrowband interference, the base station needs to obtain the interference information in the working frequency band through scanning, and send the interference information to the user terminal through broadcast information, so that the user terminal can know the interference detection result, so as to realize the spectrum shift of the control signal , to avoid interference and achieve a more refined scheduling strategy. [0003] The inventors have found that in traditional communication technologies, the base statio...
