Embodiment Construction

[0063] Reference will now be made in detail to the preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.

[0064] FIG. 5 is a schematic diagram illustrating transmission of control information according to an embodiment of the present invention, wherein changed information is separated from unchanged information.

[0065] Referring to FIG. 5, changed information and unchanged information are transmitted once per repetition period. In this embodiment, the change information is transmitted at the beginning of each repetition period. The unchanged information is transmitted after the changed information. Changed information and unchanged information having the same content are repeatedly transmitted during the repetition period. The content of the changed information and unchanged information may be changed at ...

Abstract

A method for controlling a user equipment (UE) capable of receiving a point-to-multipoint service in a wireless communication system comprises subscribing to the point-to-multipoint service. The method also comprises receiving modified point-to-multipoint control information during a certain period from the network, wherein point-to-multipoint control information is separated into at least modified point-to-multipoint control information and unmodified point- to-multipoint control information in a network. The method also comprises determining whether the modified point-to-multipoint control information comprises information associated with the point-to-multipoint service to enable reception of the point-to-multipoint service.

Description

technical field [0001] The present invention relates generally to point-to-multipoint services in wireless communication systems, and more particularly, to control messages for point-to-multipoint services. Background technique [0002] Mobile communication systems are generally not as up to the task as wired communication systems when dealing with large amounts of data. IMT-2000 is a wireless communication system designed to allow large-capacity data communication. [0003] The Universal Mobile Telecommunications System (UMTS) is a third-generation mobile communication system developed from the European Global System for Mobile Telephony (GSM) and is aimed at wireless connections based on the GSM core network and Wideband Code Division Multiple Access (W-CDMA) technologies to provide improved mobile communication services. [0004] In December 1998, ETSI in Europe, ARIB / TTC in Japan, T1 in the United States, and TTA in Korea formed the Third Generation Partnership Project...
