Abstract
The present invention discloses a method for keeping the uplink synchronization in the long-term evolving system and the system which causes the UE and Node B keep uplink synchronization in the TDD LTE system and reduce the spending of the system resource as much as possible. The Node B in the invention receives the uplink information transmitted by the UE; the Node B confirms the time advance amount TA according to the received uplink information and transmits the TA adjusting information to the UE when the TA is larger than the threshold value; and the UE sends TA to do updating to the local uplink according to the TA adjusting information in order to keep the uplink synchronization. Besides the UE in the on-data flow quantity interaction state transmits uplink pilot signal to the Node B in the assigned time-frequency resource with the existing uplink resource. The system comprises the UE and the Node B connected with the UE wherein the Node includes a receiving unit a measuring unit and a transmitting unit.
