1. A method in a wireless communication network for providing control information from a first radio node to at least one second radio node, wherein a plurality of pilot channels is available between the first radio node and the at least one second radio node, the method comprising:
defining a set of unique pilot sequences;
assigning, by the first radio node, specific pilot sequences from the set of unique pilot sequences to specific pilot channels of the plurality of pilot channels, thereby forming a pilot sequence assignment pattern representing the control information; and
providing the control information from the first radio node to the at least one second radio node by transmitting the assigned specific pilot sequences on the specific pilot channels.
