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 can be implemented in a radio technology such as Universal Terrestrial Radio Access (UTRA) or CDMA-2000. TDMA can be implemented in a radio technology such as Global System for Mobile communications (GSM) / General Packet Radio Service (GPRS) / Enhanced Data rates for GSM Evolution (EDGE). OFDMA can be implemented in 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. IEEE802.16m is an evolution of IEEE 802.16e, and provides backward compatibility with IEEE 802.16-based systems. UTRA is part of the Universal Mobile Telecomm...

Abstract

A method and apparatus for maintaining Multimedia Broadcast Multicast Service (MBMS) Minimized Drive Test (MDT) configuration in a wireless communication system is provided. The user equipment (UE) receives the first MBMS-MDT configuration via the first system information, and receives the second system information. The second system information may or may not include the second MBMS-MDT configuration. If the second system information does not include the second MBMS-MDT configuration or the second system information includes the second MBMS-MDT configuration that is equivalent to the first MBMS-MDT configuration, the UE maintains the first MBMS-MDT configuration.

Description

technical field [0001] The present invention relates to wireless communication, and more particularly, to a method and apparatus for maintaining a Multimedia Broadcast Multicast Service (MBMS) Minimized Drive Test (MDT) configuration in a wireless communication system. Background technique [0002] Universal Mobile Telecommunications System (UMTS) is a third generation (3G) asynchronous mobile communication system operating in 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 under discussion through the 3rd Generation Partnership Project (3GPP) that standardizes UMTS. [0003] 3GPP LTE is a technology for enabling high-speed packet communication. A number of proposals have been proposed for LTE goals including aiming to reduce user and provider costs, improve service quality, and expand and enhance coverage and system perf...
