上行链路物理信号

5G NR 中适用于 PUSCH 的解调和相位跟踪参考信号（DM-RS 和 PT-RS）和探测参考信号 (SRS)

基站使用 DM-RS 和 SRS 来辅助执行信道估计并为测量提供支持。对于相位噪声补偿，基站使用 PUSCH PT-RS。

NR PUSCH Resource Allocation and DM-RS and PT-RS Reference Signals
Learn about the effects of PUSCH resource allocation on the time-frequency structure of DM-RS and PT-RS.

Configure and generate sounding reference signals (SRS) for uplink transmission.

Use sounding reference signals (SRS) for synchronization, channel estimation, and uplink channel state information (CSI) estimation.
