Abstract:
1. A method for improving the accuracy of a radio timing measurement made by a terminal, comprising: making a first radio timing measurement for a radio transmission source at a time T* making a second radio timing measurement for said radio transmission source at a time T* determining a third radio timing measurement for said radio transmission source at a time T* according to a timing reference in said terminal based, at least in part, on said first radio timing measurement; determining a fourth radio timing measurement for said radio transmission source at said time T* based, at least in part, on said second radio timing measurement; determining a fifth radio timing measurement for said radio transmission source at said time T* based, at least in part, on said third radio timing measurement and said fourth radio timing measurement; making radio timing measurements for said radio transmission source at 2M (M≧1) sequential times T* determining a radio timing measurement for said radio transmission source at said time T* for each of said 2M timing measurements for said radio transmission source at said 2M sequential times; and determining a sixth radio timing measurement for said radio transmission source at said time T* based, at least in part, on said 2M radio timing measurements for said radio transmission source at said time T* determined from each of said 2M sequential radio timing measurements at times T*
