Abstract: 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.

Abstract: Disclosed are systems and methods for enhancing sounding resource signal (SRS) communications. In some embodiments, power control parameters and/or spatial relation information is determined prior to transmissions of the SRS signal. The determination may include a dynamic determination or a selection of a power control parameter set from a plurality of power control parameter sets. In some embodiments, cross-SRS interference is reduced when multiple transmissions utilize a same resource by applying orthogonal cover codes (OCC) to the resources prior to transmission.

Abstract: A method and apparatus are provided for wireless communication between a base station and a user equipment (UE). A base station apparatus includes a transceiver; and a processor configured to transmit, to the UE, via the transceiver, a control message configured for the UE, and receive, via the transceiver, a sounding reference signal (SRS) from the UE, based on the control message. The control message indicates a triggering slot offset and an available slot to the UE for the SRS transmission.
