Abstract:
1. A method, in a mobile station, for finding carriers on which transmissions are being made in a part of a radio communication network, the method comprising: selecting a carrier in a set of carriers of a discontinuous transmission scheme where signals are transmitted on the carriers of the set in active transmission intervals of a transmission cycle, said discontinuous transmission scheme specifying a transmission sequence of said set of carriers, and wherein said selecting is based on probability settings provided for the carriers of the set; scanning the selected carrier during a time range that is a fraction of the transmission cycle; confirming the presence of the selected carrier if transmissions are detected and otherwise (a) adjusting the probability settings of the carriers of the set, based on a timing of the scanning and a position of the selected carrier's active transmission interval in the transmission sequence, and (b) repeating the selection of a carrier based on the adjusted probability settings and repeating the adjusting of probability settings until the presence of a carrier has been confirmed.
