Enhanced in-device coexistence interference avoidance using predetermined downlink channel

A user equipment device, comprising:

• a first radio component and a second radio component on a shared platform, wherein the first radio component comprises a long term evolution (LTE) radio component;
• at least one hardware processor;
• a non-transitory computer-readable storage medium coupled to the at least one hardware processor and storing programming instructions for execution by the at least one hardware processor, wherein the programming instructions instruct the at least one hardware processor to:
• detect, at the first radio component, in-device coexistence interference at a first channel frequency and unavailable channel frequencies;
• send a coexistence interference indication message to a radio access network, wherein the coexistence interference indication message indicates the in-device coexistence interference and the unavailable channel frequencies;
• and
• in response to a response message comprising one or more control parameters for establishing a second channel frequency for the first radio component being received within a predetermined transition time period, enable the first radio component to use the second channel frequency based on the one or more control parameters, wherein the response message is received at a downlink signaling channel frequency that is different from the first channel frequency.

A non-transitory computer-readable medium storing instructions which, when executed by a hardware processor, cause a computing device to perform operations comprising:

• detecting, at a long term evolution (LTE) radio component, in-device coexistence interference at a first channel frequency and unavailable channel frequencies;
• sending a coexistence interference indication message to a radio access network, wherein the coexistence interference indication message indicates the in-device coexistence interference and the unavailable channel frequencies;
• and
• in response to a response message comprising one or more control parameters for establishing a second channel frequency for the LTE radio component being received within a predetermined transition time period, enabling the LTE radio component to use the second channel frequency based on the one or more control parameters, wherein the response message is received at a downlink signaling channel frequency that is different from the first channel frequency.
