A method comprising: configuring separate radio pathways, including a first radio pathway and a second radio pathway that are operable for either contiguous frequency transmissions or non-contiguous frequency transmissions, to collectively produce a composite signal in a contiguous frequency mode; generating, via the first radio pathway, a first frequency segment of the composite signal in accordance with a segment bandwidth; generating, via the second radio pathway, a second frequency segment of the composite signal in accordance with the segment bandwidth, the second frequency segment being contiguous with the first frequency segment in a frequency domain; applying, via the first radio pathway, first cyclic shift delay, CSD, phase shifts in the frequency domain to the first frequency segment to produce a first output signal; applying, via the second radio pathway, second CSD phase shifts in the frequency domain to the second frequency segment to produce a second output signal; and transmitting the composite signal by transmitting signals comprising the first output signal and the second output signal, characterized in that the first CSD phase shifts and the second CSD phase shifts are equivalent to CSD phase shifts that correspond to a contiguous non-composite signal having a single frequency segment of a bandwidth being equal to the bandwidth of the composite signal, wherein the first CSD phase shifts and the second CSD phase shifts are applied such that a device receiving the composite signal can use the CSD phase shifts that correspond to the contiguous non-composite signal; wherein configuring the radio pathways comprises setting, in the first radio pathway, a first CSD offset for the first frequency segment, wherein the first CSD phase shifts are based on the first CSD offset, and wherein configuring the radio pathways comprises setting, in the second radio pathway, a second CSD offset for the second frequency segment, wherein the second CSD phase shifts are based on the second CSD offset. configuring separate radio pathways, including a first radio pathway and a second radio pathway that are operable for either contiguous frequency transmissions or non-contiguous frequency transmissions, to collectively produce a composite signal in a contiguous frequency mode; generating, via the first radio pathway, a first frequency segment of the composite signal in accordance with a segment bandwidth; generating, via the second radio pathway, a second frequency segment of the composite signal in accordance with the segment bandwidth, the second frequency segment being contiguous with the first frequency segment in a frequency domain; applying, via the first radio pathway, first cyclic shift delay, CSD, phase shifts in the frequency domain to the first frequency segment to produce a first output signal; applying, via the second radio pathway, second CSD phase shifts in the frequency domain to the second frequency segment to produce a second output signal; and transmitting the composite signal by transmitting signals comprising the first output signal and the second output signal, characterized in that the first CSD phase shifts and the second CSD phase shifts are equivalent to CSD phase shifts that correspond to a contiguous non-composite signal having a single frequency segment of a bandwidth being equal to the bandwidth of the composite signal, wherein the first CSD phase shifts and the second CSD phase shifts are applied such that a device receiving the composite signal can use the CSD phase shifts that correspond to the contiguous non-composite signal; wherein configuring the radio pathways comprises setting, in the first radio pathway, a first CSD offset for the first frequency segment, wherein the first CSD phase shifts are based on the first CSD offset, and wherein configuring the radio pathways comprises setting, in the second radio pathway, a second CSD offset for the second frequency segment, wherein the second CSD phase shifts are based on the second CSD offset.
