Description

technical field

[0001] The present invention relates to a mobile communication system providing high-speed downlink packet access (HSDPA) service, in particular to a method for simultaneously enabling the network and the terminal to respectively support backward compatibility in the multi-carrier HSDPA system. Background technique

[0002] One of the most important features of the third-generation mobile communication system is to provide comprehensive support for high-speed mobile packet data services, including video, streaming media, and file downloads. With the increasing demand of mobile communication users for high-speed packet data services, and to better compete with other wireless technologies' increasing support capabilities for data services, the Third Generation Partnership Project (3GPP) The HSDPA technology was introduced in the Rel5 version. HSDPA uses Adaptive Coding and Modulation (AMC) and Hybrid Automatic Repeat (HARQ) technology to add a high-speed downl...
