An apparatus, method and computer program for a mobile transceiver and for a base station transceiver. The method includes receiving a downlink signal from a base station transceiver of the mobile communication system via a downlink data channel, identifying a line of sight component of at least the first positioning symbol of the downlink signal based on the one or more sequences of zero-value samples and determining information related to a location of the mobile transceiver based on the one or more non-zero-value samples received within the line of sight component of the first positioning symbol. The downlink signal includes one or more positioning symbols having a first positioning symbol, wherein the first positioning symbol is based on samples in a time domain to be transmitted by the base station transceiver.
