| 摘要 |
Systems and apparatus are disclosed for managing signalling of channel state information (CSI). A user equipment performs channel state information measurements in measurement subframes (402,404). The user equipment receives an uplink triggering grant from a base station (406), with the uplink triggering grant specifying a measurement subframe for which channel state information is to be reported. The channel state information triggering uplink grant specifics a measurement subframe at least a designated number of subframes back from an uplink communication subframe in which the channel state information is to be reported. At the uplink communication subframe corresponding to the channel state information triggering uplink grant, the user equipment reports (408) the channel state information measured at the specified measurement subframe. |
