Techniques for sending signaling in a wireless communication system are described. Communication is executed between a micro-cell base station and a mobile terminal in the micro-cell, and between a spot-cell base station and the mobile terminal in the spot cell. wherein R is defined in the specification. The system also receives an indication of the molecular weights detected when analyzing the biomolecules to which the molecular tags have been associated. At least the selection control or the indication which has to be adjusted is kinematically linked with a selection cam comprising a profile corresponding to two states 0, 1, corresponding to a non-selection state and a selection state respectively, the control device comprising means for connecting the adjustment control to each of the selected time indications.
