Abstract

The invention discloses a method for avoiding coexistence interference in terminal equipment. The terminal equipment comprises an LTE (long term evolution) module of an LTE system, and a non-LTE module of other wireless systems, wherein the LTE module can detect the ICO (in-device coexistence) interference problem. The method comprises: the LTE module estimates the ICO interference condition, and sends an ICO interference indication message to an evolved NodeB (eNB), wherein the ICO interference indication message comprises an unavailable frequency list and TDM (time division multiplexing) mode information; the eNB judges the ICO interference avoiding mode according to the ICO interference indication message and auxiliary information sent by the terminal equipment, wherein the auxiliary information comprises a power headroom report (PHR) and a proximity indication message; and the eNB sends a terminal behavior instruction message to the terminal equipment according to the judgment result to instruct the terminal equipment to perform corresponding operation. According to the technical scheme of the invention, the ICO interference problem can be preferably solved, and the user experience and system performance can be enhanced.

Description

technical field [0001] The invention relates to network communication technology, in particular to a method for avoiding coexistence interference in terminal equipment. Background technique [0002] In 3GPP Release 10, it is determined to study the issue of interference avoidance in terminal equipment In-device coexistence (ICO, In-device coexistence) and carry out corresponding standardization work. Due to the currently ubiquitous availability of access networks, users are equipped to access different networks in different areas and maintain their connectivity everywhere. For this reason, more and more user terminals are now equipped with multiple wireless transceivers, so the design is becoming more and more complex, and more challenges need to be solved to integrate multiple different transceivers on the same device platform while maintaining good performance. performance. One of the most difficult challenges is coexistence interference between transceivers of radios wi...
