2.TM2, transmit diversity mode: It is suitable for the complicated and interfering cell edge channels, and sometimes it is also used for high-speed situations.

Diversity can provide diversity gain. Mscbsc Mobile Communication Forum has 300,000 communication professionals and more than 500,000 copies of GSM/3G and other communication technical materials. It is a leading community focusing on communication technology and communication life in China. (u3p 1hg2o/L5a5k

3.TM3, open-loop spatial diversity: suitable for high-speed mobile terminals (UE).
