1. A base station being arranged to handle connection in an Orthogonal Frequency Division Multiplexing (OFDM) system, the base station comprising:
a transmitter configured for transmitting downlink communication to a user equipment utilising a resource sub-space of an entire multi-carrier resource space of the OFDM system,
wherein the resource sub-space comprises a pilot resource configuration within a set of at least two different pilot resource configurations,
wherein the resource sub-space comprises a carrier having both pilot resources and data resources within said resource sub-space; and
wherein the transmitter is further configured for transmitting information about a power level used in a transmission of at least one pilot symbol in the pilot resources.
