Sending device, receiving device and method thereof

Abstract

The invention relates to a sending device and a receiving device. The sending device (100) includes a signal processor (102) configured to: modulate bits representing control information to provide at least a first set of modulation symbols (M1) and a second set of modulation symbols (M2) ; providing a first set of mapped modulation symbols (M1') by mapping the first set of modulation symbols (M1) onto a set of frequency resources (R) within the first subband; and by mapping the second set of modulation symbols (M2) to a corresponding set of frequency resources (R') within the second subband to provide a second set of mapped modulation symbols (M2'), wherein the first set of mapped modulation symbols (M1') and the second set of mapped modulation symbols (M2' ) differ from each other in at least one modulation symbol, and wherein the first subband and the second subband are non-overlapping. The receiving device (300) includes a receiver (302) configured to receive a control signal (S c ), the control signal (S c ) includes at least the first modulation symbol set (M1) mapped to the frequency resource set (R) in the first subband and the second modulation symbol mapped to the corresponding frequency resource set (R′) in the second subband A set (M2), wherein the first set of mapped modulation symbols (M1') and the second set of mapped modulation symbols (M2') differ from each other in at least one modulation symbol and are associated with control information; the signal processor (304), which is configured based on the control signal (S c ) to get control information. Furthermore, the invention relates to corresponding methods, wireless communication systems, computer programs and computer program products.

Description

technical field [0001] The present invention relates to a transmitting device and a receiving device for a wireless communication system. Furthermore, the invention relates to corresponding methods, wireless communication systems, computer programs and computer program products. Background technique [0002] For cellular communications, especially in the uplink (UL), it is important to maintain a low Peak-to-Average-Power Ratio / Cubic Metric (PAPR / CM) of the transmitted signal , to reduce power backoff in the amplifier. This in turn provides better coverage and less power consumption for the user equipment. It is known that multi-carrier signals such as Orthogonal Frequency Division Multiplexing (OFDM) exhibit considerable PAPR / CM. One method used in the Long Term Evolution (LTE) uplink to reduce PAPR / CM is to apply a Discrete Fourier Transform (DFT) precoder, which is in An Inverse Fast Fourier Transform (IFFT) operation is previously applied to generate a Single Carrier...
