Method and apparatus for transmitting radio link failure information in wireless communication system

摘要

A method and apparatus of transmitting radio link failure (RLF) information in a wireless communication system is provided. A user equipment (UE) supports a first communication system and a second communication system. The method includes detecting an RLF at a first cell of the first communication system, and reporting an RLF report message to an eNodeB (eNB) serving the first cell based on whether or not the RLF is triggered by interference from the second communication system. In addition, a method and apparatus of restricting storing and/or reporting the RLF information in a wireless communication system is provided.

1. A method of transmitting, by a user equipment (UE), radio link failure (RLF) information in a wireless communication system, the UE supporting a first communication system and a second communication system, the method comprising:
measuring at a first cell of the first communication system; receiving an indication that a module of the second communication system is turned-on from the module; detecting an RLF at the first cell of the first communication system; storing RLF information including at least one of a cell identity of the first cell and a measurement result from either a last cell where the RLF occurred or a source cell initiating failed handover; and reporting an RLF report message including RLF information to an eNodeB (eNB) serving the first cell based on whether the RLF is triggered by interference from the second communication system, wherein the RLF information further includes in-device coexistence (IDC)-related information, wherein the IDC-related information includes information related to whether the module of the second communication system was turned on at the time the RLF occurred, and wherein the IDC-related information further includes information related to whether a measurement relating to interference caused by the second communication system was configured on at the time the RLF occurred.
