Lte系统下行多天线自适应发送的方法、装置和系统

Abstract

本发明公开一种用于LTE系统下行多天线自适应发送的方法、装置和系统。其中在用于LTE系统下行多天线自适应发送的方法中,以2天线端口模式发送小区搜索控制信息,当接收到用户终端发送的小区接入请求时,以2天线端口模式向用户终端发送查询请求;接收用户终端发送的查询响应信息,根据查询响应信息中包括的多天线端口模式信息确定用户终端能够支持的多天线端口模式,按照用户终端能够支持的多天线端口模式,向用户终端发送数据信息及相关参考信号。本发明通过查询用户终端的支持能力选择相应的多天线端口模式发送下行数据和相关参考信号,从而在充分发挥下行4天线发送的LTE系统性能的基础上,有效兼容仅支持2天线端口的LTE终端,增强了用户体验。
The invention discloses a method, device and system for downlink multi-antenna self-adaptive sending of an LTE system. According to the method for downlink multi-antenna self-adaptive sending of the LTE system, cell search control information is sent in a two-antenna-port mode, and when a cell access request sent by a user terminal is received, a query request is sent to the user terminal in a two-antenna-port mode; query response information sent by the user terminal is received, a multi-antenna-port mode capable of being supported by the user terminal is determined according to multi-antenna-port mode information contained in the query response information, and data information and related reference signals are sent to the user terminal in the multi-antenna-port mode capable of being supported by the user terminal. According to the method, device and system for downlink multi-antenna self-adaptive sending of the LTE system, the corresponding multi-antenna-port mode is selected to send downlink data and the related reference signals by inquiring the supporting capability of the user terminal, therefore, on the basis that the downlink four-antenna sending performance of the LTE system is brought into full play, an LTE terminal supporting two antenna ports is compatible effectively, and user experience is enhanced.
