  • Patent number: 11930519
    Abstract: Measurement resources are often limited in 5G and 4G-LTE communications. As a result, SMTC and CSI-RS measurement windows will occasionally be assigned to the same resource elements of a signal frame. This results in a collision that must be resolved, since both measurements cannot be performed simultaneously. The collision can be resolved using restriction, where overlapping resource elements are assigned to either the SMTC or the CSI-RS measurements, or can be resolved using measurement sharing, where overlapping resource elements are divided among the two measurements according to a measurement sharing factor. Various factors, including priority or window periodicity may be taken into account by the measurement rules that dictate collision resolution.

  • Patent number: 11929950
    Abstract: 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.

  • Publication number: 20240080224
    Abstract: Some aspects of this disclosure relate to apparatuses and methods for implementing mechanisms for a network to use Doppler shift pre-compensation values for communicating Tracking Reference Signal (TRS) to a user equipment (UE) and for implementing mechanisms for triggering the UE to measure the Doppler shift pre-compensated TRS. Some aspects of this disclosure relate to a base station including a processor that determines a Doppler shift pre-compensation value associated with the UE in response to determining that the UE is moving with a speed greater than a threshold. The processor further generates an aperiodic Tracking Reference Signal (AP-TRS) or a semi persistent TRS (SP-TRS) for the UE. The AP-TRS or the SP-TRS is decoupled from a periodic TRS (P-TRS). The processor further transmits the AP-TRS or the SP-TRS to the UE. The AP-TRS or the SP-TRS can be used for time and frequency synchronization.
