Abstract
The invention claims a method of keeping upline synchronization and system in long evolution system; it uses UE and Node B to keep upline synchronization in TDD LTE system and reduces the cost of system resource as possible. The invention Node B receives the upline information sent by UE; Node B ensures timing advance TA according to received upline information and sends TA adjustment information when the TA is bigger than threshold value time direction UE; UE sends TA to local upline to renew so as to keep upline synchronization according to said TA adjustment information. Otherwise the UE in the no data flow alternation status send upline pilot frequency signal to said Node B in appointed time frequency resource according to the existed upline resource. The system comprises UE and Node B connected with UE wherein Node B comprises receiving unit measuring unit and sending unit.
