A method for use in a wireless transmit/receive unit (WTRU) may include the WTRU receiving data symbols. The WTRU may assign the data symbols to a plurality of subcarriers in different sub-bands and map the data symbols on each of the plurality of subcarriers in the different sub-bands to a plurality of corresponding subcarriers of an inverse fast Fourier transform (IFFT) block. The WTRU may take an IFFT of the block for each sub-band and pad an output of the IFFT block with a prefix and a postfix for each sub-band. The WTRU may apply a windowing function to an output of the padding for each sub-band and form a composite signal for transmission by adding an output of the windowing of each sub-band. The WTRU may transmit the signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Pulse-shaped orthogonal frequency division multiplexing","description":"A method and apparatus for performing pulse shaping using different windowing functions for different sub-bands of a transmission is disclosed.
