Signaling and Procedure for In-Device Co-Existence

摘要

The present invention addresses apparatuses, methods and computer program product for improvement of signaling and procedure for in-device co-existence. An IDC Resolution Timer (IRT) is added at both UE and eNB sides. The IRT starts to run once UE sends IDC indication to eNB. If UE doesn't receive any IDC response from eNB after IRT expires, UE could assume that eNB rejects its IDC indication and UE could start to use other possible methods such as switching off other ISM RAT, or using autonomous denial. If UE receive IDC response from eNB before IRT expires, it will reset the IRT.

1. A method, comprising:
detecting occurrence of an in-device co-existence problem; transmitting an indication of the in-device co-existence problem occurrence to a base station; starting a timer at the time of starting the transmission ; resetting and/or stopping the timer in case a response is received from the base station before expiry of the timer; and starting an in-device co-existence problem skirting processing in case of expiry of the timer without receiving a response from the base station.
