Abstract: The present disclosure provides a band usage information generating and reporting method, a charging method, an eNB, a CN, a MME and a UE. The eNB and the UE can generate band usage information for charging, and report the band usage information to the CN, wherein the band usage information involves band usage of at least a first band and a second band, and traffic is assigned to respective bands by the eNB. The Counting entity at the eNB or UE can count the data volume of each band or ratio of data volume via different bands as the band usage information based on the scheduling information of the data. The Charging system located in the CN can process the charging and generate a bill according to the reported band usage information.

Abstract: An integrated circuit includes generation circuitry and transmission circuitry. The generation circuitry uses a reference size for a search space to generate downlink control information (DCI) in a first DCI format used for sidelink communications. The transmission circuitry transmits the DCI in the first DCI format mapped on the search space. 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. 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 is based on the third DCI format.
