Abstract
A method of operating a wireless device in a wireless communication network is provided. The method includes reporting channel state information (CSI) by generating, at the wireless device, a CSI report for transmission to a network node that uses the CSI report to make a scheduling decision, dividing the CSI report into a first CSI report portion and a second CSI report portion. The first CSI report portion includes a first payload of data and the second CSI report portion includes a second payload of data that is less than the first payload of data. The first CSI report portion is transmitted on a transmission time interval (TTI) having a first time interval value and the second CSI report portion is transmitted on a short TTI (sTTI). The first CSI report portion and the second CSI report portion include data that is combined to construct the CSI report.
