摘要： A receiver has an antenna to receive a pulse shaped transmit signal transmitted by a transmitter of a multi carrier (MC) pulse shaped transmission system. The pulse shaped transmit signal includes a predefined signal pattern. The predefined signal pattern is not subjected to pulse shaping. The receiver includes a filter to pulse shape filter the pulse shaped transmit signal to obtain data for the receiver. The predefined signal pattern is retrieved from the pulse shaped transmit signal prior to filtering the pulse shaped transmit signal.

摘要： An apparatus is configured to operate in a wireless communications network cell that is operated so as to provide a first transmission band and a second transmission band being separated by a narrow band. The apparatus is configured to transmit a data signal using a frequency band having a center frequency. The center frequency is a frequency of the narrow band. The apparatus is configured to transmit an indicator signal in the frequency band prior to transmitting the data signal so as to indicate the transmission of the data signal.
