ABSTRACT:
A system and method of wireless communication determines received signal timing deviation which is used to generate a timing advance for adjusting User Equipment (UE) transmissions. An adaptive threshold for measuring the timing deviation is set based on the energy level of received UE signals. UE signal samples which exceed the threshold are evaluated to determine timing deviation.
