Title:
METHODS FOR MEASURING AND REPORTING DOPPLER SHIFT
Document Type and Number:
WIPO Patent Application WO/2022/032567
Kind Code:
A1
Abstract:
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify an uplink resource for reporting a Doppler measurement to a base station. The UE may determine a reference signal set precedes a reference point associated with the uplink resource prior to performing Doppler measurements based on the reference signals in the reference signal set. Each reference signal in the reference signal set may occur no later than a channel state information (CSI) reference resource, or an offset relative to the uplink resource defined by a number of symbols. The UE may determine the Doppler measurement based on the reference signal set, or multiple reference signal sets and may transmit the Doppler measurement to the base station in the uplink resource.
