Claim 15:
16. The mobile device of claim 15, wherein the transmission path comprises a primary transmission path that includes the first antenna and the reception path is a secondary reception path that includes the second antenna, wherein the mobile device further has a primary reception path that includes the first antenna and a secondary transmission path that includes the second antenna, wherein the at least one processor is further configured to:
send at least one additional signal on the primary transmission path and to receive the at least one additional signal on a third reception path; and
send a plurality of signals on the secondary transmission path and to receive each signal from the plurality of signals on a different reception path, including at least the primary reception path and the third reception path;
wherein the at least one processor is configured to determine the transmission and reception group delay by being configured to determine a first group delay for the primary transmission path and the primary reception path and a second group delay for the secondary transmission path and the secondary reception path based on times of departure and times of arrivals of transmitted signals and received signals.
