Embodiment Construction

[0028] The techniques described below can be used in various wireless communication systems such as Code Division Multiple Access (CDMA), Frequency Division Multiple Access (FDMA), Time Division Multiple Access (TDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single Carrier Frequency division multiple access (SC-FDMA), etc.). CDMA may be implemented by a radio technology such as Universal Terrestrial Radio Access (UTRA) or CDMA2000. TDMA may be implemented by a radio technology such as Global System for Mobile communications (GSM) / General Packet Radio Service (GPRS) / Enhanced Data rates for GSM Evolution (EDGE). OFDMA may be implemented by radio technologies such as Institute of Electrical and Electronics Engineers (IEEE) 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), IEEE 802.20, Evolved UTRA (E-UTRA), and the like. IEEE 802.16m evolved from IEEE 802.16e and provides backward compatibility with IEEE 802.16e-based systems. UTRA is part of the Universal Mobile Telecommunic...

Abstract

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.

Description

technical field [0001] The present invention relates to wireless communication, and more particularly, to a method and apparatus for transmitting radio link failure (RLF) information in a wireless communication system. Background technique [0002] The Universal Mobile Telecommunications System (UMTS) is a third-generation (3G) asynchronous mobile communication system operating with Wideband Code Division Multiple Access (WCDMA) based on the European system, Global System for Mobile Communications (GSM) and General Packet Radio Service (GPRS). Long Term Evolution (LTE) of UMTS is being discussed by the 3rd Generation Partnership Project (3GPP) standardizing UMTS. [0003] 3GPP LTE is a technology capable of high-speed packet communication. Many schemes have been proposed for the purposes of LTE, including those aimed at reducing user and provider costs, improving service quality, expanding and improving coverage and system capabilities. 3GPP LTE requires cost reduction per...
