Method for transmitting and receiving control information including configuration information for transmission and reception in communication system supporting vehicle-to-everything communication and apparatus for the same

A second user equipment (UE) comprising:

• a processor,
• wherein the processor causes the second UE to:
• transmit, to a first UE, sidelink control information (SCI) including first resource allocation information which indicates a first sidelink resource set used for a first sidelink communication for a third UE;
• identify a sidelink resource excluding the first sidelink resource set indicated by the SCI;
• and
• perform a monitoring operation on the identified sidelink resource to receive sidelink data from the first UE.

A first user equipment (UE) comprising:

• a processor,
• wherein the processor causes the first UE to:
• receive, from a second UE, sidelink control information (SCI) including first resource allocation information which indicates a first sidelink resource set used for a first sidelink communication between the second UE and a third UE;
• select a sidelink resource excluding the first sidelink resource set indicated by the SCI;
• and
• transmit, to the second UE, sidelink data using the selected sidelink resource.

A second user equipment (UE) comprising:

• a processor,
• wherein the processor causes the second UE to:
• transmit, to a first UE, sidelink control information (SCI) including first resource allocation information which indicates a first sidelink resource set used for a first sidelink communication between the second UE and a third UE;
• identify a sidelink resource excluding the first sidelink resource set indicated by the SCI;
• and
• perform a monitoring operation on the identified sidelink resource to receive sidelink data from the first UE.

A first user equipment (UE) comprising:

• a processor,
• wherein the processor causes the first UE to:
• receive control information including resource allocation information from a second UE;
• receive, data from the second UE through a radio resource indicated by the resource allocation information included in the control information;
• generate sidelink control information (SCI) including reception configuration information indicating the radio resource used for transmission of the data by the second UE based on the resource allocation information;
• and
• transmit the SCI to a third UE,
• wherein the radio resource indicated by the reception configuration information is used for communications between the first UE and the second UE, and
• wherein the radio resource indicated by the reception configuration information is not used for communications between the first UE and the third UE.

A first user equipment (UE) comprising:

• a processor,
• wherein the processor causes the first UE to:
• receive sidelink control information (SCI) from a second UE;
• identify a format index included in the SCI;
• and
• obtain reception configuration information included in the SCI when the format index indicates that the SCI includes the reception configuration information,
• wherein the reception configuration information includes information indicating a radio resource allocated for first data transmitted from a third UE to the second UE,
• wherein the radio resource indicated by the reception configuration information is used for communications between the second UE and the third UE, and
• wherein the radio resource indicated by the reception configuration information is not used for communications between the second UE and the first UE.
