<p>A method of determining a set of Zero Correlation Zone (ZCZ) lengths, comprises: determining the length of a root sequence, and selecting such a set of ZCZ lengths that, for any cell radius, the maximum number of preambles obtained from a ZCZ length which is selected from the selected set of ZCZ lengths is closest to the maximum number of preambles determined from a ZCZ length which is selected from the set of all integers, wherein the maximum number of preambles is determined from the length of the root sequence and a ZCZ length selected. Also provided are an apparatus, a base station and a mobile communication system of determining a set of ZCZ lengths. This invention provides a technical solution for selecting a better limited set of ZCZ lengths by which signaling overload is reduced.</p> |
