- the DCI carried by the PDCCH is transmitted in a polarization coding manner.
- the cyclic redundancy check (CRC) encoder used in Polar coding is a linear encoder and generates What is generated is the system code. Therefore, the CRC encoder can be regarded as a generator matrix, and the information bit (Bit) multiplied by the generator matrix can get the CRC bit. After the CRC bit is generated, the bit stream obtained by cascading the information bit and the CRC bit is interleaved, so that a part of the CRC bits originally located at the end of the bit stream is replaced before the information bit, and the information bit is located before the CRC bit with which it has a check relationship. In this way, when decoding, the decoded part of the information bits can be CRC checked. If the check fails, the decoding is stopped, thereby realizing the early stop function of the decoding. Therefore, it becomes an inevitable requirement to cascade an interleaver after the CRC encoder.
- the maximum interleaving length of the interleaving matrix supported in the related art is 164 bits. That is to say, in the related art, the total number of DCI bits and CRC bits carried by the PDCCH shall not exceed 164 bits. Generally, the CRC bit length is fixed to 24 bits, so the information bits of the DCI shall not exceed 140 bits. However, it should be noted that in different communication systems, the limit on the number of information bits may change accordingly, and is not limited to the case where the upper limit of the DCI information bits is 140 bits.

- the present application provides a scheduling method that supports simultaneous scheduling of more cells under the condition of coding capacity limitation, thereby effectively reducing UE power consumption, reducing signaling overhead, and improving the utilization efficiency of transmission resources.
