Abstract

Claims (53)

1. A method of transmitting and receiving a signal by a user equipment (UE) in a wireless communication system, the method comprising:

receiving N control resource set #0s (CORESET #0s) based on a first subcarrier spacing (SCS); and

receiving N synchronization signal blocks (SSBs) based on a second SCS different from the first SCS,

wherein the SSBs are continuously located in a time domain, and

wherein the CORESET #0s are located in a slot including an earliest SSB in the time domain among the SSBs, and the CORESET #0s are continuously located from symbol #0 in the slot.

2. The method of claim 1 , wherein the first SCS is twice the second SCS.

3. The method of claim 2 , wherein a first extended cyclic prefix (ECP) is applied to the CORESET #0s, and

wherein a second ECP is applied to the SSBs.

4. The method of claim 3 , wherein the first ECP is configured such that a length of one slot with a reference SCS matches a length of M slots,

wherein the second ECP is configured such that the length of the one slot with the reference SCS matches a length of L slots,

wherein M and L are 2 μ2-μ1 and 2 μ3-μ1 , respectively, and

wherein μ1 denotes a value of related to the reference SCS, μ2 denotes a value of μ related to the first SCS, and μ3 denotes a value of related to the second SCS.

5. The method of claim 3 , wherein the first ECP is configured such that a length of a half-slot with a reference SCS matches a length of M slots,

wherein the second ECP is configured such that the length of the half-slot with the reference SCS matches a length of L slots,

wherein M and L are 2 μ2-μ1 and 2 μ3-μ1-1 , respectively, and

wherein μ1 denotes a value of μ related to the reference SCS, μ2 denotes a value of μ related to the first SCS, and μ3 denotes a value of related to the second SCS.

6. A user equipment (UE) configured to transmit and receive a signal in a wireless communication system, the UE comprising:

at least one transceiver;

at least one processor; and

at least one memory operably connected to the at least one processor and configured to store instructions that, when executed, cause the at least one processor to perform operations comprising:

receiving N control resource set #0s (CORESET #0s) based on a first subcarrier spacing (SCS); and

receiving N synchronization signal blocks (SSBs) based on a second SCS different from the first SCS,

wherein the SSBs are continuously located in a time domain, and

wherein the CORESET #0s are located in a slot including an earliest SSB in the time domain among the SSBs, and the CORESET #0s are continuously located from symbol #0 in the slot.

7. The UE of claim 6 , wherein the first SCS is twice the second SCS.

8. The UE of claim 7 , wherein a first extended cyclic prefix (ECP) is applied to the CORESET #0s, and

wherein a second ECP is applied to the SSBs.

9. The UE of claim 8 , wherein the first ECP is configured such that a length of one slot with a reference SCS matches a length of M slots,

wherein the second ECP is configured such that the length of the one slot with the reference SCS matches a length of L slots,

wherein M and L are 2 μ2-μ1 and 2 μ3-μ1 , respectively, and

wherein μ1 denotes a value of μ related to the reference SCS, μ2 denotes a value of μ related to the first SCS, and μ3 denotes a value of μ related to the second SCS.

10. The UE of claim 8 , wherein the first ECP is configured such that a length of a half-slot with a reference SCS matches a length of M slots,

wherein the second ECP is configured such that the length of the half-slot with the reference SCS matches a length of L slots,

wherein M and L are 2 μ2-μ1-1 and 2 μ3-μ1-1 , respectively, and

wherein μ1 denotes a value of μ related to the reference SCS, μ2 denotes a value of μ related to the first SCS, and μ3 denotes a value of μ related to the second SCS.

11. An apparatus for a user equipment (UE), the apparatus comprising:

at least one processor; and

at least one computer memory operably connected to the at least one processor and configured to, when executed, cause the at least one processor to perform operations comprising:

receiving N control resource set #0s (CORESET #0s) based on a first subcarrier spacing (SCS); and

receiving N synchronization signal blocks (SSBs) based on a second SCS different from the first SCS,

wherein the SSBs are continuously located in a time domain, and

wherein the CORESET #0s are located in a slot including an earliest SSB in the time domain among the SSBs, and the CORESET #0s are continuously located from symbol #0 in the slot.

12. The apparatus of claim 11 , wherein the first SCS is twice the second SCS.

13. The apparatus of claim 12 , wherein a first extended cyclic prefix (ECP) is applied to the CORESET #0s, and

wherein a second ECP is applied to the SSBs.

14. The apparatus of claim 13 , wherein the first ECP is configured such that a length of one slot with a reference SCS matches a length of M slots,

wherein the second ECP is configured such that the length of the one slot with the reference SCS matches a length of L slots,

wherein M and L are 2 μ2-μ1 and 2 μ3-μ1 , respectively, and

wherein μ1 denotes a value of μ related to the reference SCS, μ2 denotes a value of μ related to the first SCS, and μ3 denotes a value of μ related to the second SCS.

15. The apparatus of claim 13 , wherein the first ECP is configured such that a length of a half-slot with a reference SCS matches a length of M slots,

wherein the second ECP is configured such that the length of the half-slot with the reference SCS matches a length of L slots,

wherein M and L are 2 μ2-μ1-1 and 2 μ3-μ1-1 , respectively, and

wherein μ1 denotes a value of μ related to the reference SCS, μ2 denotes a value of μ related to the first SCS, and μ3 denotes a value of μ related to the second SCS.
