Abstract: A user equipment (UE) receives a radio signal which includes a time-frequency grid of radio resource elements. A UE detector measures a signal quality parameter associated with a subset of the radio resource elements in the time-frequency grid. The subset of the radio resource elements is less than a total number of the radio resource elements in the time-frequency grid and corresponds to an individual radio channel. Radio circuitry in the UE reports to a network node the signal quality parameter measured for the subset of the radio resource elements in the time-frequency grid to enable an operation related, for example, to the individual radio channel.
