Access resource determination method and device, storage medium, and terminal

1. An access resource determination method, performed by a User Equipment (UE) and comprising:

obtaining an offset between a narrowband Control Resource SET0 (CORESET0) and a CORESET0; and

determining a frequency domain resource of the narrowband CORESET0 according to the offset;

wherein the offset is an offset between a lowest PRB of the CORESET0 and a lowest PRB of narrowband CORESET0.

2. The method according to claim 1 , wherein a lowest Physical Resource Block (PRB) of the narrowband CORESET0 is equal to a lowest PRB of the CORESET0.

3. The method according to claim 1 , wherein an offset between a lowest PRB of the narrowband CORESET0 and a lowest PRB of the CORESET0 is a preset value.

4. The method according to claim 1 , wherein the offset is included in a CORESET0 table, or an expanded CORESET0 table.

5. The method according to claim 4 , wherein based on that a bandwidth of the narrowband CORESET0 is less than or equal to a preset bandwidth, the offset in the expanded CORESET0 table is equal to the offset in the CORESET0 table.

6. The method according to claim 1 , wherein the offset is included in a reserved field or a codepoint in a Physical Broadcast Channel (PBCH).

7. The method according to claim 1 , comprising determining a monitoring occasion of a narrowband Type0-PDCCH, wherein said determining a monitoring occasion of a narrowband Type0-PDCCH comprises:

obtaining a time slot index of the monitoring occasion of the narrowband Type0-PDCCH, based on a time offset between a start time slot of an SS/PBCH block and a start time slot of the monitoring occasion of the narrowband Type0-PDCCH, or a time offset between a start time slot of a first SS/PBCH block and a start time slot of a monitoring occasion of a first narrowband Type0-PDCCH.

8. The method according to claim 7 , wherein said obtaining a time slot index of the monitoring occasion of the narrowband Type0-PDCCH comprises obtaining a start time slot index of the monitoring occasion of the narrowband Type0-PDCCH.

9. The method according to claim 7 , wherein the time offset is included in a Type0-PDCCH monitoring occasion table, or the time offset is included in an expanded Type0-PDCCH monitoring occasion table.

10. The method according to claim 9 , wherein based on that a bandwidth of the narrowband CORESET0 is less than or equal to a preset bandwidth, the time offset in the expanded Type0-PDCCH monitoring occasion table is equal to the time offset in the Type0-PDCCH monitoring occasion table.

11. The method according to claim 7 , wherein the time offset is a time corresponding to a sum of a first offset and a first duration, the first offset is a number of time slot offsets between the start time slot of the SS/PBCH block and the start time slot of the monitoring occasion of the Type0-PDCCH or a number of time slot offsets between the start time slot of the first SS/PBCH block and the start time slot of the monitoring occasion of the first Type0-PDCCH, and the first duration is a total number of timeslots of the monitoring occasion of the Type0-PDCCH associated with a maximum number of SS/PBCH blocks.

12. The method according to claim 7 , wherein based on that a reciprocal of a number of monitoring occasions of the Type0-PDCCH in a time slot is 1 or ½, the time offset is a time corresponding to a sum of a first offset and a first duration, the first offset is a number of time slot offsets between the start time slot of the SS/PBCH block and the start time slot of the monitoring occasion of the Type0-PDCCH or a number of time slot offsets between the start time slot of the first SS/PBCH block and the start time slot of the monitoring occasion of the first Type0-PDCCH, and the first duration is a total number of timeslots of the monitoring occasion of the Type0-PDCCH associated with a maximum number of SS/PBCH blocks.

13. The method according to claim 7 , wherein the time offset is equal to a time offset between the start time slot of the SS/PBCH block and a start time slot of a monitoring occasion of a Type0-PDCCH, or a time offset between the start time slot of the first SS/PBCH block and a start time slot of a monitoring occasion of a first Type0-PDCCH, and the time slot index or start time slot index of the monitoring occasion of the narrowband Type0-PDCCH is equal to a time slot index or start time slot index of the monitoring occasion of the Type0-PDCCH plus one.

14. The method according to claim 7 , wherein based on that a reciprocal of a number of monitoring occasions of the Type0-PDCCH in a time slot is 2, the time offset is equal to a time offset between the start time slot of the SS/PBCH block and a start time slot of a monitoring occasion of a Type0-PDCCH, or a time offset between the start time slot of the first SS/PBCH block and a start time slot of a monitoring occasion of a first Type0-PDCCH, and the time slot index or start time slot index of the monitoring occasion of the narrowband Type0-PDCCH is equal to a time slot index or start time slot index of the monitoring occasion of the Type0-PDCCH plus one.

15. The method according to claim 1 , further comprising:

receiving the narrowband CORESET0 at the frequency domain resource of the narrowband CORESET0, and/or receiving a narrowband Type0-PDCCH at the monitoring occasion of the narrowband Type0-PDCCH.

16. The method according to claim 1 , further comprising:

indicating presence of the narrowband CORESET0 and/or a narrowband Type0-PDCCH in a PBCH.

17. A non-transitory storage medium storing one or more programs, the one or more programs comprising computer instructions, which, when executed by a processor of a User Equipment (UE), cause the processor to:

obtain an offset between a narrowband Control Resource SET0 (CORESET0) and a CORESET0; and

determine a frequency domain resource of the narrowband CORESET0 according to the offset;

wherein the offset is an offset between a lowest PRB of the CORESET0 and a lowest PRB of narrowband CORESET0.
