用于在异步码分多址(CDMA)通信系统中，使用多媒体CODEC的可缩放性，提供基于多数据速率的业务的方法和装置，其提供多媒体广播和多播业务(MBMS)。整个小区区域被分成第一区和第二区。特定数据被分为第一数据和第二数据。第一数据被发送到第一区，以及第二数据被发送到第二区。第一电功率控制器控制用于第一数据的电功率。第二电功率控制器控制用于第二数据的电功率。位于第二区内的用户设备(UE)接收第一数据和第二数据。位于第二区内的UE组合第一数据和第二数据从而生成一个数据项。 A method and apparatus for providing a service based on multiple data rates using scalability of a multimedia CODEC in an asynchronous code division multiple access (CDMA) communication system, which provides a multimedia broadcast and multicast service (MBMS). An entire cell area is divided into a first area and a second area. Specific data is separated into first data and second data. The first data is transmitted to the first area, and the second data is transmitted to the second area. A first electric power controller controls electric power for the first data. A second electric power controller controls electric power for the second data. A user equipment (UE) located in the second area receives the first data and the second data. The UE located in the second area combines the first data and the second data, thereby generating one data item.
