Abstract: 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.

The cophasing indicator identifies a selected entry of a codebook of cophasing coefficients where the number of bits in the cophasing indicator is identified by at least one of the beam count indicator and the rank indicator. In this way, feedback for both a rank indicator and a beam count indicator may be possible which may allow robust feedback and variably sized cophasing and beam index indicators.
