Abstract
A method for maintaining upward synchronization in a long term evolution system maintains upward synchronization between the UE and the Node B and reduces the spending of the system resource in the TDD LTE system. The Node B receives the upward information transmitted from the UE; the Node B determines the timing advance TA according to the received upward information and send down the TA adjusting message to the UE just when the TA is greater than the threshold value; the UE updates the local upward transmitting TA to maintain upward synchronization according to the TA adjusting message. In addition the UE which is in the state of no data flow interaction transmits the upward pilot signal to the Node B in the designated time-frequency resource via the existing upward resource. There is also a system thereof.
