Abstract

Claims (46)

1. A method for performing, by a first device, wireless communication, the method comprising:

receiving a TDD-UL-DL configuration information, from a base station, including information related to a first slot pattern and information related to a second slot pattern,

wherein the information related to the first slot pattern includes information related to a periodicity of the first slot pattern and information related to a first UL resource, and

wherein the information related to the second slot pattern includes information related to a periodicity of the second slot pattern and information related to a second UL resource;

determining a value related to granularity, based on i) the periodicity of the first slot pattern, ii) the periodicity of the second slot pattern and iii) a first subcarrier spacing (SCS) related to SL communication; and

transmitting a physical sidelink broadcast channel (PSBCH), to a second device, including information related to the first UL resource and information related to the second UL resource,

wherein the information related to the first UL resource and information related to the second UL resource are expressed based on a unit related to a second SCS, and

wherein the second SCS is obtained based on a value obtained by dividing the first SCS by the value related to the granularity.

2. The method of claim 1 , wherein based on a sum of the periodicity of the first slot pattern and the periodicity of the second slot pattern being 4 ms and the first SCS being 120 kHz, the value related to the granularity is 2.

3. The method of claim 1 , wherein based on a sum of the periodicity of the first slot pattern and the periodicity of the second slot pattern being 5 ms, and the first SCS being 120 kHz, the value related to the granularity is 2.

4. The method of claim 1 , wherein based on the periodicity of the first slot pattern being 5 ms, the periodicity of the second slot pattern being 5 ms, and the first SCS being 60 kHz, the value related to the granularity is 2.

5. The method of claim 1 , wherein based on the periodicity of the first slot pattern being 10 ms, the periodicity of the second slot pattern being 10 ms, and the first SCS being 30 kHz, the value related to the granularity is 2.

6. The method of claim 1 , wherein based on the periodicity of the first slot pattern being 5 ms, the periodicity of the second slot pattern being 5 ms, and the first SCS being 120 kHz, the value related to the granularity is 4.

7. The method of claim 1 , wherein based on the periodicity of the first slot pattern being 10 ms, the periodicity of the second slot pattern being 10 ms, and the first SCS being 60 kHz, the value related to the granularity is 4.

8. The method of claim 1 , wherein based on the periodicity of the first slot pattern being 10 ms, the periodicity of the second slot pattern being 10 ms, and the first SCS being 120 kHz, the value related to the granularity is 8.

9. The method of claim 1 , wherein information related to the first UL resource includes a number of slots related to the first UL resource, and

wherein information related to the second UL resource includes a number of slots related to the second UL resource.

10. The method of claim 1 , wherein the information related to the first UL resource and the information related to the second UL resource, included in the PSBCH are expressed by 7 bits.

11. The method of claim 10 , wherein the information related to the first UL resource and the information related to the second UL resource are expressed based on a maximum number of UL slots which can exist in a period of the first slot pattern, expressed based on an unit related to the second SCS.

12. The method of claim 11 , wherein the information related to the first UL resource and the information related to the second UL resource is expressed as a sum of:

a number of slots related to the first UL resource expressed based on the unit related to the second SCS; and

a value obtained by multiplying a value obtained by adding 1 to the maximum number of UL slots which can exist in the period of the first slot pattern, expressed based on the unit related to the second SCS, by a number of slots related to the second UL resource expressed based on the unit related to the second SCS.

13. The method of claim 11 , wherein the information related to the first UL resource and the information related to the second UL resource is expressed as a sum of:

a value obtained by subtracting 1 from a number of slots related to the first UL resource expressed based on the unit related to the second SCS; and

a value obtained by multiplying a value obtained by adding 1 to the maximum number of UL slots which can exist in the period of the first slot pattern, expressed based on the unit related to the second SCS, by a number of slots related to the second UL resource expressed based on the unit related to the second SCS.

14. A first device for performing wireless communication, the first device comprising:

one or more memories storing instructions;

one or more transceivers; and
