Adaptive transmission method and a base station using the method

Abstract:

The invention relates to a method, a base station and a computer program for selecting a spatial transmission method for a next downlink transmission in a base station. The base station can be a WiMAX, a UMTS or a 3 GPP LTE base station. According to the invention the base station makes a selection between beamforming (BF), space-time coding (STC) or MIMO for a next downlink frame. The selection is based on uplink measurements and feedback information from a particular mobile station whereto the next downlink frame is to be transmitted.

Abstract(Chinese):

本发明涉及一种用于在基站中为下一次下行链路传输选择空间传输方法的方法，基站和计算机程序。基站可以是WiMAX，UMTS或3GGPP LTE基站。根据本发明，基站在波束形成（BF），空时编码（STC）或下一个下行链路帧的MIMO之间进行选择。该选择基于来自特定移动台的上行链路测量和反馈信息，下一个下行链路帧将被发送。
