Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. An integrated circuit, comprising:
generation circuitry, which, in operation, uses a reference size for a search space to generate downlink control information (DCI) in a first DCI format used for sidelink communications, and
a transmission circuitry, which is coupled to the generation circuitry and which, in operation, transmits the DCI in the first DCI format mapped on the search space;
wherein,
when a second DCI format used for base station communications is mapped on the search space and the second DCI format is larger than the first DCI format, the reference size for the search space is based on the second DCI format, and
when a third DCI format used for sidelink communications is mapped on the search space and the third DCI format is larger than the first DCI format, and the second DCI format larger than the third DCI format is not mapped on the search space, the reference size for the search space is based on the third DCI format.
