WAVEFORM BASED DATA INTEGRITY CHECK AND ERROR CORRECTION

A wireless transmit/receive unit (WTRU) may low-density parity-check (LDPC) encode data into LDPC blocks. Further, the WTRU may produce and append a cyclic redundancy check (CRC) to each of the LDPC blocks. Also, the WTRU may concatenate the plurality of LDPC blocks and appended CRCs. Additionally,...

Summary:A wireless transmit/receive unit (WTRU) may low-density parity-check (LDPC) encode data into LDPC blocks. Further, the WTRU may produce and append a cyclic redundancy check (CRC) to each of the LDPC blocks. Also, the WTRU may concatenate the plurality of LDPC blocks and appended CRCs. Additionally, the WTRU may produce information associated with error checks. Moreover, the WTRU may produce a codeword using a codebook. The codeword may be based on the information associated with the error checks. In addition, the WTRU may produce an orthogonal frequency-division multiplex (OFDM) signal by mapping the codeword and the concatenated plurality of LDPC blocks and appended CRCs onto resource elements of the OFDM signal. Further, the WTRU may transmit the produced OFDM signal. In a further example, the WTRU may produce an additional CRC in addition to the appended CRCs, and the produced OFDM signal may include the additional CRC.
