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.
Claims16
A user equipment (UE) 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) including a downlink control information (DCI),
- wherein the DCI includes an uplink cancellation indication(UL CI) indicating cancellation or non-cancellation of UL transmission in a UL bandwidth part (BWP),
- wherein the RRC configuration information includes a resource indication value (RIV) related to a reference resource region,
- wherein the RIV is related to an index of a starting resource block (RB) and a number of consecutive RBs,
- wherein the index of the starting RB is used to determine an index of a starting physical resource block (PRB) of the reference resource region,
- wherein the RIV related to the reference resource region is interpreted under an assumption that a size of the UL BWP is 275 RBs, and
- wherein a symbol parameter related to resources for which the cancellation or non-cancellation of the UL transmission is indicated by the UL CI in the reference resource region is determined by a subcarrier spacing of a downlink (DL) BWP in which the DCI is monitored.
A method for receiving downlink control information (DCI) in a wireless communication system, the method comprising:
- receiving radio resource control (RRC) configuration information;
- and
- receiving a physical downlink control channel (PDCCH) including a DCI,
- wherein the DCI includes an uplink cancellation indication(UL CI) indicating cancellation or non-cancellation of UL transmission in a UL bandwidth part (BWP),
- wherein the RRC configuration information includes a resource indication value (RIV) related to a reference resource region,
- wherein the RIV is related to an index of a starting resource block (RB) and a number of consecutive RBs,
- wherein the index of the starting RB is used to determine an index of a starting physical resource block (PRB) of the reference resource region,
- wherein the RIV related to the reference resource region is interpreted under an assumption that a size of the UL BWP is 275 RBs, and
- wherein a symbol parameter related to resources for which the cancellation or non-cancellation of the UL transmission is indicated by the UL CI in the reference resource region is determined by a subcarrier spacing of a downlink (DL) BWP in which the DCI is monitored.
