Abstract
This invention presents a synchronization method for uplink, and is based on UE JT technology. During downlink, UE sets up the downlink synchronization; UE undertakes the downlink channel estimation; UE, according to the estimated downlink channel estimation result, constructs transport matrix A, and the uplink synchronization code matrix d to be transmitted by UE. Then UE obtains the uplink pilot frequency transmission data s, which includes the latest downlink channel fading and multi-path information.
