Embodiment 1

[0037] Embodiment 1 of the present invention provides a reporting method for avoiding intra-device interference, such as figure 1 shown, including:

[0038] In step 101, the user terminal determines an in-device coordination mechanism between the LTE frequency band and radio frequency bands other than the LTE frequency band. The LTE frequency band is the frequency band used by the LTE radio frequency module to send and receive signals. The radio frequency band outside the LTE frequency band is the frequency band used by the radio frequency modules other than the LTE radio frequency module to send and receive signals. For example, the frequency band used by the WIFI radio frequency module to send and receive signals. The two may in the same frequency band.

[0039] Step 102, the user terminal reports to the base station an in-equipment coordination mechanism between the LTE frequency band and radio frequency bands other than the LTE frequency band.

[0040] The intra-device c...

Embodiment 2

[0049]Embodiment 2 of the present invention provides a reporting method for avoiding intra-device interference, wherein LTE and WIFI are negotiated within the device in the full-band WIFI, and no negotiation is performed with Bluetooth, such as figure 2 shown, including:

[0050] In step 201, the UE determines the intra-device coordination mechanism of LTE and radios other than LTE.

[0051] Among them, the in-device coordination mechanism between LTE and radio other than LTE refers to the coordination mechanism between the LTE frequency band in the device and the radio frequency band other than the LTE frequency band, that is, the LTE radio frequency module in the device and other radio frequency modules transmit and receive on the LTE frequency band Signal coordination mechanism, for example, when the LTE frequency band includes Band1, Band2, and Band3, the LTE radio frequency module shares Band1 with other radio radio frequency modules, and the LTE radio frequency module u...

Embodiment 3

[0062] Embodiment 3 of the present invention provides a reporting method for avoiding intra-device interference, wherein there is intra-device negotiation between LTE and WIFI in some frequency bands, and there is no negotiation with Bluetooth, and the reporting method is based on UE capabilities, such as image 3 shown, including:

[0063] In step 301, the UE determines the intra-device coordination mechanism of LTE and radios other than LTE.

[0064] Among them, the in-device coordination mechanism between LTE and radio other than LTE refers to the coordination mechanism between the LTE frequency band in the device and the radio frequency band other than the LTE frequency band, that is, the LTE radio frequency module in the device and other radio frequency modules transmit and receive on the LTE frequency band Coordination mechanism when signaling.

[0065] In step 302, the UE reports the in-device coordination mechanism of the base station LTE and radios other than LTE.

Abstract

Disclosed are a reporting method and device for avoiding intra-device interference. The method comprises: a user terminal determining an intra-device coordination mechanism for the LTE frequency band and the radio frequency band beyond the same and reporting the intra-device coordination mechanism for the LTE frequency band and the radio frequency band beyond the same to a base station. In the embodiments of the present invention, a user terminal notifies a base station of its own intra-device coordination mechanism, and the base station can thus avoid intra-device interference of the user terminal according to the intra-device coordination mechanism thereof.

Description

technical field [0001] The present invention relates to the communication field, in particular to a reporting method and equipment for avoiding interference within equipment. Background technique [0002] Smart terminal devices require the same device to support multiple wireless access technologies, for example, the same device supports both LTE (Long Term Evolution, long-term evolution) and ISM (including Bluetooth, wireless local area network, etc.), and supports both LTE and GPS (Global Positioning System , Global Positioning System) positioning technology, etc. For these wireless access technologies in the same device, if a single radio frequency module design is used, mutual interference is unavoidable, especially in application scenarios with partially overlapping frequency bands or adjacent frequency bands. [0003] For example, the equipment coexistence interference problem between the high-frequency part of the LTE frequency band Band 40 (2300MHz-2400MHz) and the ...
