Abstract
A disclosure of the present specification provides a method for transmitting data by a transmitter. The method may comprise the steps of: when a transport block (TB) is divided into n data blocks, adding additional information after each of the n data blocks; and adding a cyclic redundancy check (CRC) after the last additional information. Here, the CRC may be generated on the basis of the n data blocks, and the n pieces of additional information added after each of data blocks.
Claims17
A method of transmitting data at a transmitter, the method comprising:
- generating an information sequence based on the data;
- encoding the information sequence based on a channel code;
- and
- transmitting the encoded information sequence,
- wherein the information sequence includes data blocks 0 to N−1 related to the data and parity blocks 0 to N−1 in the order of data block 0, parity block 0, data block 1, parity block 1, . . . , data block N−1, parity block N−1, where N is an integer larger than 1, and
- wherein each parity block n of the parity blocks 0 to N−1 is generated based on bits included in data blocks 0 to n−1 and bits included in data block n only, among the data blocks 0 to N−1.
A transmitter for transmitting data, the transmitter comprising:
- a transceiver;
- and
- a processor operably coupled to the transceiver, the processor configured to:
- generate an information sequence based on the data;
- encode the information sequence based on a channel code;
- and
- control the transceiver to transmit the encoded information sequence,
- wherein the information sequence includes data blocks 0 to N−1 related to the data and parity blocks 0 to N−1 in the order of data block 0, parity block 0, data block 1, parity block 1, . . . , data block N−1, parity block N−1, where N is an integer larger than 1, and
- wherein each parity block n of the parity blocks 0 to N−1 is generated based on bits included in data blocks 0 to n−1 and bits included in data block n only, among the data blocks 0 to N−1.
A receiver for receiving data, the receiver comprising:
- a transceiver;
- and
- a processor operably coupled to the transceiver, the processor configured to:
- control the transceiver to receive an encoded information sequence related to the data;
- and
- perform decoding on the encoded information sequence based on a channel code to obtain an information sequence,
- wherein the information sequence includes data blocks 0 to N−1 related to the data and parity blocks 0 to N−1 in the order of data block 0, parity block 0, data block 1, parity block 1, . . . , data block N−1, parity block N−1, where N is an integer larger than 1, and
- wherein each parity block n of the parity blocks 0 to N−1 is related to bits included in data blocks 0 to n−1 and bits included in data block n only, among the data blocks 0 to N−1.
