Abstract
Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive a plurality of downlink transmissions from a base station. The UE may identify a channel state information (CSI) trigger event. The UE may transmit an accumulated CSI report comprising CSI for each downlink transmission of the plurality of downlink transmissions in accordance with the CSI trigger event, wherein a quantization level of the CSI for each downlink transmission in the accumulated CSI report is based at least in part on a time between the downlink transmission and the CSI trigger event.

An apparatus for wireless communication at a user equipment (UE), comprising:
- a memory:
- and
- a processor coupled with the memory and configured to:
- receive a plurality of downlink transmissions from a base station:
- identify a channel state information trigger event;
- and
- transmit an accumulated channel state information report comprising channel state information for each downlink transmission of the plurality of downlink transmissions in accordance with the channel state information trigger event, wherein a quantization level of the channel state information for each downlink transmission in the accumulated channel state information report is based at least in part on a time between the downlink transmission and the channel state information trigger event.
