Title:
DIFFERENTIAL DEMODULATION REFERENCE SIGNAL BASED CHANNEL QUALITY REPORTING
Document Type and Number:
WIPO Patent Application WO/2023/184070
Kind Code:
A1
Abstract:
Methods, systems, and devices for wireless communications at a user equipment (UE) are described. The UE may receive a synchronization signal block or channel state information reference signal. The UE may transmit a channel state information report including a first indication of channel quality associated with the synchronization signal block or channel state information reference signal. The UE may receive a demodulation reference signal that is quasi co-located with the synchronization signal block or channel state information reference signal and associated with a physical downlink shared channel. The UE may transmit a hybrid automatic repeat request acknowledgment message or channel state information report including a second indication of channel quality associated with the demodulation reference signal of the physical downlink shared channel. The second indication of channel quality may include a differential measurement that is relative to the first indication of channel quality.
