## Abstract

Provided in the present invention are a method performed by user equipment, and user equipment. The method performed by user equipment includes: determining, according to sidelink control information (SCI) format 2-C, the content of SCI; and transmitting the SCI, wherein a field in the SCI indicates that the SCI is used to carry inter-UE coordination information, or indicates that the SCI is used to carry a coordination request, wherein the inter-UE coordination information is triggered by the UE according to a certain condition, or is a response to a coordination request transmitted by second user equipment (UE), and the coordination request is used to request inter-UE coordination information from third user equipment (UE).

## Claims

### Claim at position 1

1-2. (canceled)

### Claim 3

A user equipment (UE), comprising:
a processor; and
a memory, having instructions stored therein,
wherein the instructions, when run by the processor, perform:
determining contents of sidelink control information (SCI) format 2-C, wherein:
candidate values of a field in the SCI format 2-C include a first value and a second value;
the first value indicates that the SCI format 2-C is used for conveying inter-UE coordination information; and
the second value indicates that the SCI format 2-C is used for conveying a request for inter-UE coordination information, and
transmitting the SCI format 2-C.

### Claim 4

A user equipment (UE), comprising:
a processor; and
a memory, having instructions stored therein,
wherein the instructions, when run by the processor, perform:
receiving sidelink control information (SCI) format 2-C, wherein:
candidate values of a field in the SCI format 2-C include a first value and a second value;
the first value indicates that the SCI format 2-C is used for conveying inter-UE coordination information; and
the second value indicates that the SCI format 2-C is used for conveying a request for inter-UE coordination information.

### Claim 5

A method performed by user equipment (UE), the method comprising:
determining contents of sidelink control information (SCI) format 2-C, wherein:
candidate values of a field in the SCI format 2-C include a first value and a second value;
the first value indicates that the SCI format 2-C is used for conveying inter-UE coordination information; and
the second value indicates that the SCI format 2-C is used for conveying a request for inter-UE coordination information, and
transmitting the SCI format 2-C.
