METHOD AND USER EQUIPMENT FOR ADJUSTING TIME OFFSET

摘要

A method for adjusting Time Advance (TA) is disclosed, and is applicable to a system having multiple serving cells. The method includes: measuring arrival time of a downlink signal of a cell, and obtaining downlink delay information of the measured cell according to the arrival time of the downlink signal; and adjusting TA of uplink sent data according to the downlink delay information. Because the UE measures the downlink delay information, the signal detection performance is improved, and the interference to other surrounding UEs is reduced.
