Description

technical field [0001] The present invention relates to the communication field, and more particularly, relates to a data transmission mode setting and detection device and method, which can be applied to a wireless communication system. Background technique [0002] At present, 3G mobile communication technology is gradually mature and commercially available, and 3GPP2 CDMA20001XEV-DO can further provide a competitive wireless access system in the next few years. However, in order to maintain competitiveness in the next decade or decades, it is necessary to introduce new wireless access technologies. At present, the industry has reached a preliminary consensus on the evolution of 3GPP2 air interface technology, which is divided into two stages. The first stage adopts multi-carrier EV-DO technology, and more consideration is given to compatibility. It is only a short-term evolution project; the second stage is AIE (Air Interface Evolution ) is to introduce more advanced tec...
