Abstract

Disclosed is a method in which a user equipment receives downlink control information in a wireless communication system. The user equipment may receive configuration information for reception of a physical downlink control channel (PDCCH) from a base station, and may receive a PDCCH including downlink control information (DCI) on the basis of the configuration information.

Claims (59)

1. A user equipment configured to operate in a wireless communication system, the user equipment comprising:

a communication module; and

a processor configured to control the communication module,

wherein the processor is configured to,

receive radio resource control (RRC) configuration information, and

receive a physical downlink control channel (PDCCH) related to a downlink control information (DCI) of a specific format,

wherein the DCI includes an uplink cancellation indication (UL CI) for cancellation of an UL transmission in a UL bandwidth part (UL BWP) within a resource region,

wherein the UL CI is associated with the resource region in a time domain and a frequency domain, and

wherein the resource region excludes a specific resource from a reference resource region, and

wherein a number of symbols in the reference resource region is determined based on a monitoring periodicity of the PDCCH or a predetermined value.

2. The user equipment of claim 1 ,

wherein a symbol parameter related to at least one symbol included in the resource region for which the cancellation or non-cancellation of the UL transmission is indicated by the UL CI is determined based on a subcarrier spacing of a downlink bandwidth part (DL BWP) in which the DCI of the specific format is monitored.

3. The user equipment of claim 1 ,

wherein the specific resource comprises at least a symbol for a synchronization signal physical broadcast channel (SS/PBCH) block and/or a downlink symbol.

4. The user equipment of claim 1 ,

wherein a starting symbol in the reference resource region is a symbol positioned after X symbols from a symbol in which the PDCCH is received.

5. The user equipment of claim 4 ,

wherein the X is determined based on a subcarrier spacing, and

wherein the subcarrier spacing is a smallest value between the subcarrier spacing of the DL BWP in which the DCI is monitored, and a smallest subcarrier spacing among subcarrier spacings of uplink cells.

6. The user equipment of claim 1 ,

wherein the resource region includes a plurality of resources of which the cancellation or the non-cancellation of the UL transmission is indicated by respective bits of the UL CI.

7. The user equipment of claim 1 ,

wherein the resource region includes a plurality of first groups on a time domain, each of which includes one or more symbols and at least one second group on a frequency domain, which includes at least one physical resource block (PRB).

8. The user equipment of claim 1 ,

wherein, when scheduling information for transmitting a physical uplink shared channel (PUSCH) is received before receiving the PDCCH related to the DCI including the UL CI,

the UL transmission is cancelled when a region indicated by the UL CI in the resource region overlaps with UL resources allocated for the PUSCH.

9. The user equipment of claim 1 ,

wherein an index of a starting PRB of the reference resource region is obtained by adding an offset value to an index of a starting RB.

10. The user equipment of claim 9 ,

wherein the RRC configuration information includes a resource indication value (RIV) related to the index of the starting RB and a number of consecutive RBs, and

wherein the RIV related to the reference resource region is interpreted under an assumption that a size of the UL BWP is 275 RBs.

11. A method for receiving downlink control information in a wireless communication system, the method comprising:

receiving radio resource control (RRC) configuration information; and

receiving a physical downlink control channel (PDCCH) related to a downlink control information (DCI) of a specific format,

wherein the DCI includes an uplink cancellation indication (UL CI) for cancellation or of an UL transmission in a UL bandwidth part (UL BWP) within a resource region,

wherein the UL CI is associated with the resource region in a time domain and a frequency domain, and

wherein the resource region excludes a specific resource from a reference resource region, and

wherein a number of symbols in the reference resource region is determined based on a monitoring periodicity of the PDCCH or a predetermined value.

12. The method of claim 11 ,

wherein a symbol parameter related to at least one symbol included in the resource region for which the cancellation or non-cancellation of the UL transmission is indicated by the UL CI is determined based on a subcarrier spacing of a downlink bandwidth part (DL BWP) in which the DCI of the specific format is monitored.

13. The method of claim 11 ,

wherein the specific resource comprises at least a symbol for a synchronization signal physical broadcast channel (SS/PBCH) block and/or a downlink symbol.

14. The method of claim 11 ,

wherein a starting symbol in the reference resource region is a symbol positioned after X symbols from a symbol in which the PDCCH is received.

15. The method of claim 14 ,

wherein the X is determined based on a subcarrier spacing, and

wherein the subcarrier spacing is a smallest value between the subcarrier spacing of the DL BWP in which the DCI is monitored, and a smallest subcarrier spacing among subcarrier spacings of uplink cells.

16. The method of claim 11 ,

wherein the resource region includes a plurality of resources of which the cancellation or the non-cancellation of the UL transmission is indicated by respective bits of the UL CI.

17. The method of claim 11 ,

wherein the resource region includes a plurality of first groups on a time domain, each of which includes one or more symbols and at least one second group on a frequency domain, which includes at least one physical resource block (PRB).

18. The method of claim 11 ,

wherein, when scheduling information for transmitting a physical uplink shared channel (PUSCH) is received before receiving the PDCCH related to the DCI including the UL CI,

the UL transmission is cancelled when a region indicated by the UL CI in the resource region overlaps with UL resources allocated for the PUSCH.

19. The user equipment of claim 11 ,

wherein an index of a starting PRB of the reference resource region is obtained by adding an offset value to an index of a starting RB.

20. The user equipment of claim 19 ,

wherein the RRC configuration information includes a resource indication value (RIV) related to the index of the starting RB and a number of consecutive RBs, and

wherein the RIV related to the reference resource region is interpreted under an assumption that a size of the UL BWP is 275 RBs.
