[0073] Determine the value of N'in Matching TBS. If N info Less than or equal to 3824

[0074] Where R is less than or equal to 1 / 4, If R is greater than 1 / 4, and N′ info Greater than or equal to 8424 If R is greater than 1 / 4, and N′ info Less than 8424,

[0117] Here, the single carrier signal waveform is mapped to the same time domain resource through layer mapping and precoding, as shown in FIG. 5.

[0118] In some embodiments, the terminal supports multi-carrier transmission, and the terminal supports carrier aggregation in the related art, and CQI feedback is performed for each carrier, and a carrier aggregation mode is configured. As shown in FIG. 6, if the CQIs of the two codewords corresponding to a certain carrier, e.g., CC1, are the same, i.e., the codewords corresponding to CC1 only include codeword 0, one TB is transmitted; if the CQIs of the two codewords corresponding to a certain carrier, e.g., CC2, are different, i.e., the codewords corresponding to CC2 only include codeword 0 and codeword 1, two TBs are transmitted.

[0119] Here, the signal waveform of each carrier in the multi-carrier is mapped to the same time domain resource through layer mapping and precoding, as shown in FIG. 6.

[0120] In some embodiments, the network device divides all the links into two sets according to the CQI, all the links in set 1 have the same CQI, and all the links in set 2 have different CQI. CQI feedback is performed for each link (the links of different carriers belong to the same cell).

[0121] In some embodiments, the terminal supports multi-carrier transmission, and the terminal supports new spectrum aggregation, and only set 1 exists in the terminal, and a new spectrum aggregation-single TB mode is configured. As shown in FIG. 7, the CQIs corresponding to multiple links are the same, i.e., the CQIs corresponding to the multiple links are all codeword 0, one TB is jointly transmitted by the multiple links, and different links transmit different symbols of the same stream data; in the TBS calculation process, the number of N' includes the part of the multiple links. RE In some embodiments, the terminal supports multi-carrier transmission, and the terminal supports new spectrum aggregation, and only set 1 exists in the terminal, and a new spectrum aggregation-single TB mode is configured. As shown in FIG. 7, the CQIs corresponding to multiple links are the same, i.e., the CQIs corresponding to the multiple links are all codeword 0, one TB is jointly transmitted by the multiple links, and different links transmit different symbols of the same stream data; in the TBS calculation process, the number of N' includes the part of the multiple links.

[0122] Here, the carrier signal waveforms in each of the multiple links in the same CQI are mapped into the same time domain resource by layer mapping, precoding and FDM; the carrier signal waveforms corresponding to each link can adopt different precoding manners, for example, precoding 1 and precoding 2.

[0123] In some embodiments, the terminal supports multi-carrier transmission, and the terminal supports new spectrum aggregation, and only set 2 exists in the terminal, then the new spectrum aggregation-multi-TB mode is configured, as shown in FIG. 8, the CQIs of the multiple links are all different, that is, the CQIs corresponding to the multiple links include code word 0 and code word 1, and each of the multiple links transmits one TB respectively.

[0124] Here, the carrier signal waveforms in each of the multiple links in the different CQIs are mapped into the same time domain resource by layer mapping, precoding and FDM; the carrier signal waveforms corresponding to each link can adopt different precoding manners, for example, precoding 1 and precoding 2.

[0125] In some embodiments, the terminal supports multi-carrier transmission, and the terminal supports new spectrum aggregation, and both set 1 and set 2 exist in the terminal, then the new spectrum aggregation-hybrid TB mode is configured, TB1 is transmitted by the multiple links jointly, and TB2 is transmitted by a single link, that is, the multiple links with the same CQI jointly transmit one TB1, and each of the multiple links with different CQIs transmits one TB2. Here, the calculation of the number of N' in the TBS calculation process corresponding to TB1 includes the part of the multiple links. RE

[0126] As shown in FIG. 9, the new spectrum aggregation-hybrid TB mode can have the case that the multiple links jointly transmit one TB, or the case that each of the multiple links transmits one TB; the carrier signal waveforms in each of the multiple links are mapped into the same time domain resource by layer mapping, precoding and FDM; the carrier signal waveforms corresponding to each link can adopt different precoding manners, for example, precoding 1 and precoding 2.

[0127] Exemplarily, the link corresponding to code word 0 in the multiple links maps the carrier signal waveforms on the link into the same time domain resource by layer mapping, precoding 1, precoding 2 and FDM; the link corresponding to code word 1 in the multiple links maps the carrier signal waveforms on the link into the same time domain resource by layer mapping, precoding and FDM.

[0128] ​Step 404, the terminal monitors the corresponding DCI format according to the configured transmission mode, and performs correct HARQ feedback.

[0129] If the single carrier transmission mode is configured, the terminal monitors the DCI format 1-1, and feeds back 1bit ACK / NACK when there is one TB, and feeds back 2bit ACK / NACK when there are two TBs.

[0130] If the carrier aggregation mode in the related art is configured, when a single carrier is scheduled by single DCI, the terminal monitors the DCI format 1-1, and feeds back 1bit ACK / NACK when there is one TB, and feeds back 2bit ACK / NACK when there are two TBs; when multiple carriers are scheduled by single DCI, the terminal monitors the DCI format 1-3, and feeds back 1bit ACK / NACK when there is one TB for each CC, and feeds back 2bit ACK / NACK when there are two TBs.

[0131] If the new spectrum aggregation-single TB mode is configured, the terminal needs to monitor a new first DCI format, as shown in Table 5, the difference between the first DCI format and the DCI format 1-3 is that the Scheduled cell set indicator / Scheduled cells indicator is changed to Scheduled link set indicator / Scheduled links indicator, and the other fields are the same; or the terminal monitors the DCI format 1-3, and understands the Scheduled cell set indicator / Scheduled cells indicator as the Scheduled link set indicator / Scheduled links indicator. In addition, the first DCI format has an MCS / NDI / RV field and multiple TDRA / FDRA fields; the terminal performs CRC check after receiving all the data of the links, and feeds back 1bit ACK / NACK.

[0132] Table 5

[0133] If the new spectrum aggregation - multi-TB mode is configured, the terminal needs to monitor a new second DCI format, as shown in Table 6, the difference between the second DCI format and the DCI format 1-3 is that the Scheduled cell set indicator / Scheduled cells indicator is changed to the Scheduled link set indicator / Scheduled links indicator, and the other fields are the same; or the terminal monitors the DCI format 1-3, and understands the Scheduled cell set indicator / Scheduled cells indicator as the Scheduled link set indicator / Scheduled links indicator. In addition, the second DCI format has multiple MCS / NDI / RV fields, multiple TDRA / FDRA fields; the terminal feeds back 1 bit of ACK / NACK for each link.

[0134] Table 6

[0135] If the new spectrum aggregation-mixed TB mode is configured, the terminal needs to monitor a new third DCI format, as shown in Table 7, the difference between the third DCI format and the DCI format 1-3 is that the Scheduled cell set indicator / Scheduled cells indicator is changed to the Scheduled link set indicator / Scheduled links indicator, and other fields are the same; or the terminal monitors the DCI format 1-3, and understands the Scheduled cell set indicator / Scheduled cells indicator as the Scheduled link set indicator / Scheduled links indicator. In addition, it is indicated in the third DCI format which links share a TB and which links transmit a TB alone; the terminal feeds back 1 bit ACK / NACK for the link jointly transmitting the TB, and also feeds back 1 bit ACK / NACK for the link transmitting the TB alone. As shown in Table 7, assuming that link 1 and link 2 share a TB, and link 3 transmits a TB alone, it is indicated in the DCI field that TB1 is transmitted through link 1 and link 2, and TB2 is transmitted through link 3, which can be directly indicated. In order to ensure the length of the DCI format, it can also be indicated by 3 bits, TB1 indicates 110, and TB2 indicates 001, which represents link 1, link 2 and link 3 from left to right.
