技术领域 FIELD

[0001] 本发明涉及通信领域,特别涉及一种LTE系统下行多天线自适应发送的方法、装置和和系统。 [0001] The present invention relates to the field of communications, particularly to a multi-antenna downlink LTE system adaptive transmission method, and apparatus and systems.

背景技术 Background technique

[0002] 针对下行多天线发送,LTE (Long Term Evolution,长期演进)系统标准定义了2X2、4X2和4X4三种发送模式。 [0002] The multi-antenna transmission for the downlink, LTE (Long Term Evolution, LTE) system standard defines three kinds of transmission modes 2X2,4X2 and 4X4. 其中,2X2为基本下行发送模式;相比与2X2模式,4X2模式可以带来更多的赋形增益、多用户增益和调度增益,但产品实现难度较大,4X4模式对终端提出了更高要求,近期产品实现可能性低。 Wherein, as the basic 2X2 downlink transmission mode; compared with model 2X2, 4X2 mode may bring more shaping gain, gain and multi-user scheduling gain, but the product difficult to achieve, 4X4 mode terminal a higher requirement recent product realization possibility is low.
