Publication number: 20230275695Abstract: 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.Type: ApplicationFiled: May 2, 2023Publication date: August 31, 2023Applicant: InterDigital Patent Holdings, Inc.Inventors: Kyle Jung-Lin Pan, Fengjun Xi, Byung K.

Publication number: 20190327116Abstract: Systems and methods are disclosed for combining successive cancellation decoding of polar coding with channel estimation, using a non-elementary mixture of information and redundancy bits for both channel estimation and error correction. For example, select bits of the polar encoder output may be used for an implicit parity check. Reliably-decoded bits may be iteratively incorporated into the set of pilots. The result is a semi-blind approach for channel estimation, which may have applicability to common wireless communication systems, particularly a cellular control channel, or transmissions of short messages on a cellular data channel.Type: ApplicationFiled: April 17, 2019Publication date: October 24, 2019Inventors: Nadim Ghaddar, Young-Han Kim, Laurence B.
