METHOD AND APPARATUS FOR COMPENSATING SIGNAL TIMING MEASUREMENTS FOR DIFFERENCES IN SIGNAL FREQUENCIES

摘要

Methods(100) and apparatuses (12, 24, 38) taught herein advantageously facilitate use of timing measurements in wireless communication networks (10) where radio signal timing measurements involve signals at different carrier frequencies. The methods and apparatuses in particular compensate such timing measurements for expected discrepancies in the measurements that arise from frequency-dependent differences in the propagation behavior of the radio signals being measured. In a non-limiting example, measurements at two or more frequencies may be compensated for the frequency distance between those frequencies, or with respect to a reference frequency. In such cases, timing measurements determined for one or more other radio signals are compensated as a function of the frequency distance between the reference frequency and the frequencies of such other radio signals.
