Abstract
A user equipment (UE) is configured with a first configuration for reporting measurement feedback information according to a first reporting cycle using a first set of parameters, and a second configuration for reporting measurement feedback information according to a second reporting cycle using a second set of parameters. The UE switches between the first cycle and the second cycle for reporting for example CQI based on for example comparing a data or a channel measurement against a predefined threshold. In various embodiments the second configuration is fixed, or results in no CQI reporting, or is variable based on a previous cycle or CQI level, or is event-based. In another embodiment, the network commands the UE to switch. The end result is that control signalling overhead can be reduced when appropriate by reducing the number of CQI reports that are sent uplink.
