Abstract: Systems and methods described herein provide Channel State Information (CSI) computation with ultra-low latency, enabling such CSI computation to be used for more Ultra-Reliable Low-Latency Communication (URLLC) use cases. The solutions proposed herein can apply the ultra-low latency timing requirement to the following URLLC scenarios: CSI computation for URLLC schemes that involve multiple Transmission/Reception Point (TRP) transmissions; CSI computation for URLLC while at least one CPU is occupied for another CSI computation (i.e., when L>0); and CSI computation for URLLC with more than 4 CSI-RS ports used for channel measurements. As a result, the solutions proposed reduce the CSI reporting latency which helps in improving the reliability of URLLC Downlink (DL) transmissions.
