摘要：
Apparatus and method of wireless communication that determines received signal timing deviation which is used to generate a timing advance for adjusting wireless transmit receive unit (WTRU) transmissions. An adaptive threshold for measuring the timing deviation is set based on the energy level of received WTRU signals. WTRU signal samples which exceed the threshold are evaluated to determine timing deviation.
