METHOD AND DEVICE FOR REALIZING TIMING ADVANCE IN UPLINK TRANSMISSION

摘要

A method for realizing timing advance in uplink transmission includes that: a user equipment receives indication signaling of the timing advance TA, and the actual timing advance TA' in uplink transmission is educed by adding the TA value corresponding to the indication signaling of TA to the adjustment offset of TA which is set in advance by the user equipment, and the user equipment sends uplink data according to the actual timing advance TA' in uplink transmission. Another method for realizing timing advance in uplink transmission is disclosed in the present invention. The improvement of the method compared to the prior art is that, an adjustment indication table of TA is set in a base station and a user equipment, and some of the table items in the adjustment indication table of TA are multiplexed in TDD system and FDD system. A device for realizing the timing advance in uplink transmission is also disclosed in the present invention. The scheme of the present invention discloses the concrete implementation of the timing advance in uplink transmission in TDD system and realizes the consistency for designing TDD system and FDD system in maximum.
