Abstract
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.
Claims11
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.
A wireless device for carrying output synchronization tracking in a wireless communication system, the wireless device comprising:
- a radio frequency (RF) unit configured to transmit and receive a wireless signal;
- and
- a processor connected to the RF unit,
- wherein the processor receives channel status information-reference signal (CSI-RS) configuration for prescribing the CSI-RS from a base station by a wireless device,
- receives tracking reference signal (TRS) configuration for prescribing the TRS from the base station by the wireless device,
- receives the CSI-RS according to the CSI-RS configuration by the wireless device,
- receives the TRS according to the TRS configuration by the wireless device, and
- tracks 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.
