Published: with international search report (Art. 21(3)) (54) Title: CHANNEL STATE INFORMATION REPORTING FOR SYSTEMS WITH MULTIPLE TRANSMISSION TIME IN- TERVALS (57) : A user equipment (UE) may establish a configuration for communication utilizing a first transmission time interval (TTI) length and a second TTI length that is shorter than the first TTI length. The first TTI length may be associated with a first traffic type (e.g., a first latency or reliability characteristic) and the second TTI length may be associated with a second traffic type (e.g., a second latency or reliability characteristic). The UE may identify a trigger for a channel state information (CSI) report associated with the second TTI length and identify a reference resource for the CSI report (e.g., having the second TTI length). The UE may generate the CSI report based on the reference resource, and may transmit the CSI report during a reporting TTI and in response on the identified trigger.
