摘要

A cellular mobile radio system in which power control is applied and in which measurement of the relative paths losses between base station and mobiles are used to compute the stability condition. In one system, mobiles are arranged to transmit a common known sequence at different times and the base stations are arranged to correlate against this sequence throughout the data transmission burst period to measure the signal levels from all mobiles within range. Base stations log the levels and times of reception. The data is aggregated over the network interconnecting the base stations to a common point. At this common point the timings of the unknown mobile signal reception peaks are matched to those of the known in other base stations in order to identify the mobile associated with every correlation peak.
