ENHANCEMENTS TO SUPPORT HST-SFN DEPLOYMENT SCENARIO - A simplified explanation of the abstract
This abstract first appeared for US patent application 18222421 titled 'ENHANCEMENTS TO SUPPORT HST-SFN DEPLOYMENT SCENARIO
Simplified Explanation
The patent application describes a device and a Transmit and Receive Point (TRP) in a High-Speed Train-Single Frequency Network (HST-SFN) that help compensate for frequency-offset in the device.
- The device receives two reference signals from a first TRP, one of which corresponds to a QCL RS of the other signal.
- The device uses the first reference signal to determine delay-spread and average-delay information for the path between the first TRP and the device.
- The device also receives a third reference signal from a second TRP, which includes Doppler-shift and Doppler-spread information.
- The third reference signal corresponds to either a QCL RS of a fourth reference signal transmitted from the second TRP or the second reference signal transmitted in a SFN manner from the first TRP.
Original Abstract Submitted
A device, such as a UE, and a Transmit and Receive Point (TRP) in a High-Speed Train-Single Frequency Network (HST-SFN) are disclosed that provide network-assisted frequency-offset compensation for the device. The device includes a receiver that receives a first reference signal and a second reference signal sent over a wireless network from a first TRP. The first reference signal corresponds to a QCL RS of the second reference signal. The device receiver determines delay-spread and average-delay information for a path between the first TRP to the device based on the first reference signal. The device receiver further receives a third reference signal from a second TRP that includes Doppler-shift and Doppler-spread information, and corresponds to a QCL RS of a fourth reference signal transmitted from the second TRP or corresponds to the second reference signal transmitted in a SFN manner from the first TRP.
