Abstract
A transmitter node is disclosed for reducing Peak to Average Power Ratio, PAPR. The transmitter node comprises circuitry configured to cause the transmitter node to transmit, to a receiver node, data in OFDM symbols. For one OFDM symbol, a real part of a first data symbol transmitted on a first subcarrier and an imaginary part of a second data symbol transmitted on a second subcarrier, different from the first subcarrier, are reserved for transmission of a PAPR reducing signal. Resource locations of the first data symbol and of the second data symbol are determined based on preconfigured reservation rules.
