1. A method in a receiving unit of a wireless network, for facilitating noise and interference measurements on an air interface, said method comprising the steps of:
- obtaining, at a receiver, information relating to a time-varying layout of a first silent resource element (RE) grid for a first cell;
measuring a signal that is received on a data channel during an RE for which no data transmission is allocated for the first cell according to the silent RE grid;
determining an amount of inter-cell interference experienced by the receiver based on the signal measurement;
taking the determined inter-cell interference into account in the reception of a control or a data channel; and
introducing a second silent RE grid on a control channel to estimate an interference that hits the control channel using code in an electronic memory.

10. A receiving unit of a wireless network, for facilitating noise and interference measurements on an air interface comprising:
-
a network interface configured to obtain information relating to a time-varying layout of a first silent resource element (RE) grid for a first cell; an electronic memory having code configured to communicate with the network interface and to the information; and a processing unit configured to; measure a signal that is received on a data channel during an RE for which no data transmission is allocated for the first cell according to the silent RE grid; determine an amount of inter-cell interference experienced by the receiver based on the signal measurement; take the determined inter-cell interference into account in the reception of a control or a data channel; and introducing a second silent RE grid on a control channel to estimate an interference that hits the control channel using code in an electronic memory. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
