Method of carrying out synchronization tracking and a wireless device using the same

摘要

There are provided a method of carrying out synchronization tracking and a wireless device using the same. The wireless device receives CSI-RS (Channel Status Information-Reference Signal) setting for prescribing the CSI-RS from a base station, and TRS (Tracking Reference Signal) setting for prescribing the TRS from the base station. The wireless device tracks the synchronization based on the TRS.

1. A method of carrying out synchronization tracking in a wireless communication system, the method comprising:
receiving channel status information-reference signal (CSI-RS) configuration for prescribing a CSI-RS from a base station by a wireless device; receiving tracking reference signal (TRS) configuration for prescribing a TRS from the base station by the wireless device; receiving the CSI-RS according to the CSI-RS configuration by the wireless device; receiving the TRS according to the TRS configuration by the wireless device; and tracking the synchronization based on the TRS by the wireless device, wherein the TRS configuration comprises information on whether an antenna port used according to the CSI-RS is used according to the TRS.
