Avoidance of Synchronization Oscillation in TD-SCDMA Uplink Synchronization |
摘要 |
Avoidance of uplink synchronization oscillation in TD-SCDMA systems begins when a user equipment receives a downlink SS command from a Node B. The user equipment obtains a previous uplink timing, which may be from a previous sub-frame associated with the downlink SS command. The user equipment would obtain this previous sub-frame associated with the SS command directly from the Node B as an identification of the Node B's sub-frame delay. The user equipment will then calculate the uplink timing for its next updated uplink signal by combining the previous uplink timing with the synchronization adjustment associated with the SS command. The user equipment then transmits its next uplink signal using the new uplink timing. |
