Systems and methods for flexible triggering of Channel State Information (CSI) reports are provided. A method performed by a wireless device for transmitting a CSI report according to a timeline requirement includes one or more of: determining to enable timeline switching; receiving an instruction to determine a first CSI report; determining to stop determining an existing ongoing second CSI report; determining the first CSI report; and transmitting the first CSI report. In this way, some embodiments allow ultra-low latency CSI reporting also for the cases when the wireless device is already in the ongoing process of determining a CSI report. In some embodiments, Ultra-Reliable Low-Latency Communication (URLLC) CSI reports are allowed to “override” previous CSI calculations. Some embodiments achieve more flexible triggering of URLLC CSI reports so that the ultra-low latency CSI timeline can be applied for more cases, reducing the CSI latency and resulting in more reliable URLLC scheduling.
