Mobile communication system

摘要

This invention uses a plurality of encoding methods for communication between a base station BS and a mobile station MS. When the base station BS encodes a transmission signal, a suitable encoding method is selected from a plurality of encoding methods based on traffic conditions, the peripheral environment of the mobile station MS, etc. The base station BS notifies which encoding method has been used to the mobile station MS. The mobile station MS recognize the encoding method used by the base station BS from the information notified from the base station BS. The mobile station MS decodes a receive signal using a method corresponding to this encoding method.
