Abstract
Measuring an end-to-end delay(s) in a distributed communications system (DCS) is disclosed. The DCS is coupled to a signal source(s) supporting multiple logical channels and includes multiple remote units each communicating in one or more of the logical channels. The DCS is configured to measure an end-to-end delay(s), which includes a path delay(s) between the signal source and the remote units and a local delay(s) at each of the remote units, for each of the logical channels. The measured end-to-end delay(s) can help the signal source to more accurately determine an equivalent coverage range of the DCS, thus making it possible to generate random access preambles for the DCS based on as few Zadoff-Chu (ZC) sequences as possible. By generating the random access preambles based on fewer ZC sequences, it is possible to minimize interference among the random access preambles, thus helping to improve random access performance in the DCS.
