the SSB 1 occupies the 8 th symbol to the 11 th symbol in the time slot.
4. The method according to claim 1 , further comprising:
sending remaining minimum system information RMSI 0 corresponding to the SSB 0 and remaining minimum system information RMSI 1 corresponding to the SSB 1 in the time slot.
5. The method according to claim 4 , wherein a physical downlink control channel (PDCCH) of the RMSI 1 carries a second indication, and the second indication indicates that a starting symbol of a physical downlink share channel (PDSCH) of the RMSI 1 is the 8 th symbol in the time slot.
6. The method according to claim 5 , wherein,
the second indication is that a resource configuration index of the PDSCH is 13.
7. A rate matching indication method, comprising:
receiving, by a terminal of a new radio unlicensed independent networking (NR-U), a synchronization signal block SSB 0 in a time slot, wherein the SSB 0 carries a first indication, and the first indication indicates a rate matching mode of deducting a time-frequency resource occupied by a synchronization signal block SSB 1 in the time slot; wherein the first indication is a subcarrier spacing (SCS) indication domain in a physical broadcast channel (PBCH) of the SSB 0.
8. The method according to claim 7 , wherein the first indication is 1 bit.
9. The method according to claim 7 , wherein the time slot further carries a physical downlink control channel (PDCCH) of remaining minimum system information RMSI 1 corresponding to the SSB 1; and
the method further comprises:
detecting, in response to determining that the PDCCH of the RMSI 1 carries a second indication, the subcarrier spacing (SCS) indication domain in the PBCH of the SSB 0 in the SSB 0; wherein
the second indication indicates that a starting symbol of a physical downlink share channel (PDSCH) of the RMSI 1 is the 8 th symbol in the time slot.
10. The method according to claim 9 , wherein the second indication is that a resource configuration index of the PDSCH is 13.
11. A terminal, comprising:
a processor; and
a memory, storing an executable instruction; wherein
the processor is configured to load and execute the executable instruction so as to realize the rate matching indication method according to claim 7 .

a processor; and
a memory, storing an executable instruction; wherein
the processor is configured to send synchronization signal blocks SSB 0 and SSB 1 in a time slot, wherein the SSB 0 carries a first indication, and the first indication indicates, to a terminal, that a rate matching mode of deducting a time-frequency resource occupied by the SSB 1 is adopted; wherein the first indication is a subcarrier spacing (SCS) indication domain in a physical broadcast channel (PBCH) of the SSB 0.
13. The device according to claim 12 , wherein the first indication is 1 bit.
14. The device according to claim 12 , wherein the time slot comprises 14 symbols;
the SSB 0 occupies the 2 nd symbol to the 5 th symbol in the time slot; and
the SSB 1 occupies the 8 th symbol to the 11 th symbol in the time slot.
15. The device according to claim 12 , wherein the processor is further configured to:
send remaining minimum system information RMSI 0 corresponding to the SSB 0 and remaining minimum system information RMSI 1 corresponding to the SSB 1 in the time slot.
16. The device according to claim 15 , wherein a physical downlink control channel (PDCCH) of the RMSI 1 carries a second indication, and the second indication indicates that a starting symbol of a physical downlink share channel (PDSCH) of the RMSI 1 is the 8 th symbol in the time slot.
