一种测量参考信号的多天线参数的配置方法及装置制造方法及图纸

本发明专利技术公开了一种测量参考信号的多天线参数配置方法及装置，用于解决现有技术中无法确定多天线SRS参数配置的问题。本发明专利技术基站通过高层信令通知UE发送SRS的参数，UE根据发送SRS的天线端口数量及预设的映射关系确定各天线端口发送SRS的参数，各天线端口的循环移位等间隔分布，且间隔取最大值；当发送SRS的天线端口数量为4时，天线端口0和天线端口1的频率梳都为kTC；部分循环移位信息对应的天线端口2和天线端口3的频率梳为kTC，其余的循环移位信息对应的天线端口2和天线端口3的频率梳为1-kTC。采用本发明专利技术的技术方案，终端可根据配置的隐含映射关系确定各天线端口发送SRS的参数，既能节省信令开销，又能保证配置的灵活性。

Configuration method and device for measuring multi antenna parameters of reference signal

The invention discloses a multi antenna parameter configuration method and a device for measuring a reference signal, which is used to solve the problem that the multi antenna SRS parameter configuration can not be determined in the prior art. The base station of the invention through the parameters of high-level signaling notify UE to send SRS, UE to determine the parameters of each antenna port to send SRS according to the number of antenna port to send SRS and preset the mapping relation between the cyclic shift distribution interval of each antenna port, and the interval of the maximum; when the number of antenna port to send 4 SRS, frequency 1 the antenna port 0 and port antenna for kTC 3 frequency comb; the antenna port information corresponding to the 2 part of the cyclic shift and comb antenna port is kTC, the frequency of 3 antenna port cycle shift information corresponding to the rest of the 2 and 1-kTC comb antenna port. By adopting the technical proposal of the invention, the terminal can determine the parameters of each antenna port sending SRS according to the implicit mapping relation of the configuration, thereby saving signaling cost and ensuring the flexibility of configuration.
