Embodiment 1

[0035] Such as image 3 As shown, it is the processing flow of the terminal side in the method for reporting the interference frequency band of the in-terminal coexistence interference provided by the embodiment of the present invention. Wherein, the processing flow will be executed under the following conditions: when the frequency band of the corresponding system of the serving base station is in the working state, if the frequency band of other systems enters the working state; or, when the frequency band of other systems is in the working state, if the serving base station corresponds to the system The frequency band enters the working state; or, when the interfered frequency band changes. The processing flow may specifically include the following steps:

[0036] Step 301, the terminal obtains the working frequency band of the serving base station. Wherein, the working frequency band is a frequency band that the serving base station can support. The terminal is a multi-...

Embodiment 2

[0050] Such as Figure 6 As shown, the processing flow on the base station side in the interference frequency band receiving method for in-terminal coexistence interference provided by the embodiment of the present invention may specifically include the following steps:

[0051] Step 601, the serving base station sends information about the working frequency band of the serving base station to the terminal, so that the terminal can determine whether the working frequency band of the serving base station is the same as the interfered frequency band after determining the frequency band interfered by other systems in the frequency band corresponding to the serving base station. frequency band.

[0052] For the processing method on the terminal side, reference may be made to Embodiment 1, which will not be repeated here.

[0053] Step 602, the serving base station receives the interference frequency band information reported by the terminal when the working frequency band of the ...

Embodiment 3

[0060] Such as Figure 7 As shown, the processing flow of the interference frequency band reporting and receiving method for in-terminal coexistence interference provided in the embodiment of the present invention in a specific application scenario may specifically include the following steps:

[0061] In step 701, the terminal receives information about the working frequency band of the serving base station sent by the serving base station in the LTE system.

[0062] Step 702, when the terminal learns that its LTE frequency band is in the working state, the adjacent ISM frequency band is switched from the non-working state to the working state, and the terminal cannot coordinate the interference of the ISM frequency band to the LTE frequency band through the internal interference coordination strategy.

[0063] Step 703, the terminal determines the frequency band interfered by the ISM frequency band in the LTE frequency band, that is, the interference frequency band.

Abstract

The invention discloses an interference frequency band reporting and receiving method of co-existing interference in a terminal and a device of the interference frequency band reporting and receiving method. The reporting method includes the following steps that the terminal obtains a working frequency band of a service base station. The terminal determines the frequency band interfered by other systems in frequency bands of a system corresponding to the service base station. The terminal judges whether the working frequency band of the service base station has the same frequency band of the interfered frequency band. If yes, the terminal reports information on the interference band to the service base station and if not, the terminal denies reporting information on the interference frequency band to the service base station. With the interference frequency band reporting and receiving method of co-existing interference in the terminal and the device of the interference frequency band reporting and receiving method, the utilization rate of system resources in the process of reporting the information on the interference frequency band can be improved.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method for reporting and receiving an interference frequency band of coexistence interference in a terminal and a device thereof. Background technique [0002] With the increasing scale of the smart terminal market, more and more terminals will integrate communication modules of various standards, such as 2G (Second Generation, second generation mobile communication system), 3G (3rd Generation, third generation mobile communication system) , LTE (Long Term Evolution, long-term evolution), WiFi (Wireless Fidelity, wireless local area network), Bluetooth, GPS (Global Positioning System, global positioning system), ISM (Industrial Scientific Medical, industrial, scientific, medical communication system) and other communication modules. When two wireless communication modules in the same terminal work in adjacent frequency bands simultaneously, intra-terminal...
