Claim 7:
8. The method of claim 7, wherein the transmission path is a primary transmission path that includes a first switch in the RF switch network and the reception path is a secondary reception path that includes a second switch in the RF switch network, wherein the mobile device further has a primary reception path that includes the first switch and a secondary transmission path that includes the second switch, the method further comprising:
switchably coupling the first switch in the primary transmission path to the second switch in the secondary reception path to receive the first signal on the reception path in the conducted closed loop;
switchably coupling the first switch in the primary transmission path to a third switch in a third reception path and sending a second signal on the primary transmission path and receiving the second signal on the third reception path;
switchably coupling the second switch in the secondary transmission path to the first switch in the primary reception path and sending a third signal on the secondary transmission path and receiving the third signal on the primary reception path; and
switchably coupling the second switch in the secondary transmission path to the third switch in the third reception path and sending a fourth signal on the secondary transmission path and receiving the fourth signal on the third reception path;
wherein determining the second transmission and reception group delay further comprises determining 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 and received first signal, second signal, third signal, and fourth signal.
