Definitions
- the second aspect provides an information carrying method, where the receiving end acquires a sequence to be decoded, and the receiving end performs a descrambling operation on the sequence to be decoded by using part or all of the identifier sequence; or, the receiving end Performing a deinterleaving operation on the sequence to be decoded by using an interleaving mode, where the interleaving mode is determined by part or all of the identification sequence, the identification sequence is used to identify a terminal, and the receiving end is to perform a descrambling operation. Or the sequence after the deinterleaving operation performs polar Polar code decoding. In this way, the problem of insufficient length of the identification sequence in the existing system is solved, and the length of the identification sequence is increased, which increases the number of terminals that can be identified by the identification sequence, and is more suitable for the application scenario of mass access in the future.
- the identification sequence for identifying the terminal is carried in the encoded bit sequence, and the encoded bit sequence carrying the identification sequence is modulated, then passed through the noise channel, and then output.
- the second bit sequence may be a rate-matched sequence or a sequence that has not undergone rate matching. If the second bit sequence is a sequence that has not undergone rate matching, after the transmitting end carries part or all of the identification sequence in the second bit sequence, the second bit sequence of the bearer identification sequence needs to be rate matched to generate the foregoing.
- the third bit sequence is a sequence that has not undergone rate matching, after the transmitting end carries part or all of the identification sequence in the second bit sequence, the second bit sequence of the bearer identification sequence needs to be rate matched to generate the foregoing.
- Step 1005 Perform descrambling on the extracted CRC information bits. This step is an optional step. If the eNB determines that the base station carries the RNTI sequence does not include the CRC bit scrambling operation, this step is omitted.
- the processing unit 1101 is configured to: sequentially buffer part or all of the identification sequence into the second bit sequence in a manner of repeating the number of times.
- the processing unit 1202 is configured to perform a descrambling operation on the sequence to be decoded acquired by the receiving unit 1201 by using part or all of the identification sequence, or to deinterleave the sequence to be decoded acquired by the receiving unit 1201 in the interleaving mode. Operation, wherein the interleaving mode is determined by part or all of the identification sequence, and the identification sequence is used to identify the terminal;
