Title:
CONFIGURATION ASPECTS OF A TRACKING REFERENCE SIGNAL IN NEW RADIO
Document Type and Number:
WIPO Patent Application WO/2019/074742
Kind Code:
A3
Abstract:
Methods, systems, and devices for wireless communications are described for configuration aspects of a tracking reference signal in New Radio. A base station may select a first burst duration and a second burst duration for a tracking reference signal (TRS) burst, the first burst duration being different from the second burst duration, and may transmit configuration information indicating the first burst duration and the second burst duration to a user equipment (UE). The base station may transmit a first TRS burst having the first burst duration and a second TRS burst having the second burst duration. The UE may detect the first TRS burst having the first burst duration and the second TRS burst having the second burst duration based at least in part on the configuration information, and perform resource tracking based at least in part on the detected first TRS burst and the second TRS burst.
