| 简介 |
Systems and methods for measuring end-to-end data path delays between a Radio Equipment Controller (REC) and a Radio Equipment (RE) of a base station are disclosed. In one embodiment, a system includes a RE configured to transmit an uplink chirped sine wave signal from the RE to a REC on an uplink data path from the RE to the REC via an asynchronous communication network. The REC is configured to correlate a reference chirped sine wave signal and a received signal from the RE. The REC is further configured to determine an uplink data path delay from the RE to the REC based on results of the correlation of the reference chirped sine wave signal and the received signal from the RE on the uplink data path. In another embodiment, a downlink data path delay is measured in a similar manner. |
