Abstract
A method in a first wireless device (WD) is described. The method includes determining one round trip time (RTT) of a first set of RTTs. The method also includes, at set intervals (TK), determining a set of mode peaks of the first set of RTTs, determining that the first SIFS mode has the highest mode peak of the set of mode peaks, determining that the second SIFS mode has the second highest peak of the set of mode peaks, determining a mode difference (TD), and adjusting the second subset of RTTs at least by adding or subtracting TD to each RTT of the second subset of RTTs. The method also includes determining a second set of RTTs comprising the first subset of RTTs and the adjusted second subset of RTTs, the second set of RTTs corresponding to the adjusted single SIFS mode.
