Patent number: 11929950Abstract: Methods and apparatuses are disclosed for calculating and compensating for Doppler shift in a high-speed environment. When in a high-speed environment, Doppler shifts on a transmitted radio frequency signal can become extremely large, which may make it difficult or even impossible for a receiving device to accurately decipher the signal. Therefore, embodiments of the present disclosure describe how tracking reference signals can be transmitted from multiple transmission/reception points, and processed by the UE. For example, the TRS transmitted from the TRP can be enhanced to allow for TRS information from two different TRPs. Additionally, or alternatively, a flag can be set within TRS information that identifies it as having originated from either a first TRP or a second TRP. Additionally, the UE can calculate Doppler shift information and report that information back to the base station in a report message, such as an SRS message. In this manner, the base station can precompensate for the Doppler shift.Type: GrantFiled: August 5, 2020Date of Patent: March 12, 2024Assignee: APPLE INC.Inventors: Haitong Sun, Wei Zeng, Yushu Zhang, Hong He, Oghenekome Oteri, Sigen Ye, Weidong Yang, Chunxuan Ye, Chunhai Yao, Dawei Zhang
