Abstract
A method and apparatus e.g. a headset or a base station for controlling channel selection in a communications system (400) using a DECT communications protocol, wherein multiple predefined channels are established using multiple carrier signals at respective carrier frequencies (F1,F2, . . . F8); comprising: transmitting (205) a first signal (S1) on multiple of the channels using automatic channel selection; transmitting a first signal and a second signal on multiple of the channels using automatic channel selection; setting a power level of carrier signals in a first group of channels to a first power level and setting a power level of carrier signals in a second group of channels to a second power level; wherein the second power level is preferably/deliberately set to a predetermined power level higher than the first power level. Wherein the first signal is transmitted in accordance with a first transmission scheme, wherein channel selection is restricted to the channels in the first group of channels, and the second signal is transmitted in accordance with the second transmission scheme, wherein channel selection is restricted to the channels in the second group of channels.
