摘要： Systems, methods, and instrumentalities are disclosed for interleaving coded bits. A wireless transmit/receive unit (WTRU) may generate a plurality of polar encoded bits using polar encoding. The WTRU may divide the plurality of polar encoded bits into sub-blocks of equal size in a sequential manner. The WTRU may apply sub-block wise interleaving to the sub-blocks using an interleaver pattern. The sub-blocks associated with a subset of the sub-blocks may be interleaved, and sub-blocks associated with another subset of the sub-blocks may not be interleaved. The sub-block wise interleaving may include applying interleaving across the sub-blocks without interleaving bits associated with each of the sub-blocks. The WTRU may concatenate bits from each of the interleaved sub-blocks to generate interleaved bits, and store the interleaved bits associated with the interleaved sub-blocks in a circular buffer. The WTRU may select a plurality of bits for transmission from the interleaved bits.

摘要： A node (110, 115) receives (804) transmissions associated with a given set of information bits, wherein each of the transmissions use a different polar code and share one or more information bits of the given set of information bits. The node determines (808), at each of a plurality of polar decoders (505, 605) of the node, soft information for each information bit included in an associated one of the transmissions, wherein each of the plurality of polar decoders is associated with a different transmission of the transmissions. The node provides (812), from each polar decoder of the plurality to one or more other polar decoders of the plurality, the determined soft information for any information bits shared by their respective associated transmissions, and uses (816) the provided soft information in an iterative decoding process to decode one or more of the received transmissions.

摘要： An encoding apparatus derives a bit order based on a puncturing table that specifies different puncturing patterns for different transmission rates. The encoding apparatus then generates an error correcting code from an input information bit string and rearranges the error correcting code in the derived bit order. The error correcting code is punctured by taking a number of consecutive bits from the rearranged error correcting code. The number of bits taken varies depending on the transmission rate. The punctured error correcting code is output to a decoding apparatus, which realigns the code bits according to the transmission rate and the puncturing table, then uses the realigned error correcting code to correct errors in erroneous data. Rearrangement of the error correcting code makes the puncturing process more efficient by avoiding the need to decide whether to take or discard each bit individually.

摘要： Disclosed is a method of improving iterative decoding of short codes within a demodulator. The vector of metrics of the bits considered at the output of the demodulator is decoded. The value of the check code of the CRC of the decoded word is compared with a predetermined value. If the value of the CRC is considered to form an acceptable message for the decoding step, the decoded word is transmitted to the recipient. If the value of the CRC is incompatible with a correctly decoded message, then the parameters for iterative decoding of the initial message are modified that were received from the demodulator and executing at least one new iterative decoding step with these new parameters.

摘要： Data puncturing ensuring orthogonality within communication systems. Puncturing is employed within communication systems to ensure orthogonality (or substantial orthogonality) of various transmissions between communication devices within communication systems. Any of a variety of types of signals can be employed herein including uncoded signals, turbo encoded signals, turbo trellis coded modulation (TTCM) encoded signals, LDPC (Low Density Parity Check) encoded signals, and RS (Reed-Solomon) encoded signals, among just some types of signals. A first transmission can be made from a first communication device to a second communication device, and the second communication device can sometimes request a subsequent transmission (e.g., a re-transmission) from the first communication device to the second communication device. Oftentimes, different information is sent from the first communication device to the second communication device within the subsequent transmission. Herein, each of these transmissions can be ensured to be orthogonal.
