一种参考信号映射方法及装置
摘要：
本发明提供一种参考信号映射方法及装置。本发明中，根据4端口或8端口参考信号图样，得到N端口参考信号图样，N为大于16的整数，比如N端口参考信号图样包括18、20、24、28或32端口的参考信号图样，并在进行参考信号映射时，根据该N端口的参考信号图样确定CSI‑RS被映射到的RE位置，根据该RE位置对CSI‑RS进行资源映射，从而实现了16端口以上CSI‑RS映射，进而实现了16端口以上CSI‑RS的传输。
摘要（英）：

The invention provides a reference signal mapping method and apparatus. An N-port reference signal pattern is obtained according to a 4-port or 8-port reference signal pattern, wherein the N is an integer greater than 16 and the N-port reference signal pattern includes an 18-port, 20-port, 24-port, 28-port or 32-port reference signal pattern. When reference signal mapping is carried out, a mapped RE position of a CSI-RS is determined based on the N-port reference signal pattern; and according to the RE position, resource mapping is carried out on the CSI-RS, so that CSI-RS mapping with more than 16 ports can be realized and thus transmission of CSI-RS with more than 16 ports can be realized.
