Abstract
A user apparatus configured to perform transmission of a discovery signal by radio, including: means that determines a resource group pattern to be used by the user apparatus based on information transmitted from a base station, and determines a resource group including one discovery resource or a plurality of discovery resources that can be used for transmitting the discovery signal from among one resource group or a plurality of resource groups included in the resource group pattern; and means that selects a discovery resource to be used for transmitting the discovery signal from among the determined resource group.
Claims15
A user apparatus configured to perform transmission of a discovery signal by radio, comprising:
- a processor and a memory, wherein the processor:
- determines a resource group pattern that includes one or more resource groups for transmitting the discovery signal, to be used by the user apparatus based on information transmitted from a base station;
- determines one of the resource groups including one discovery resource or a plurality of discovery resources that can be used for transmitting the discovery signal from among the one or more resource groups;
- and
- selects a discovery resource to be used for transmitting the discovery signal from among the determined resource group.
A base station configured to transmit a control signal to a user apparatus that performs transmission of a discovery signal by radio, comprising:
- a processor and a memory, wherein the processor:
- transmits, to the user apparatus, a control signal including information indicating a resource group pattern that includes one or more resource groups for transmitting the discovery signal;
- and
- transmits, to the user apparatus, information to be used for determining one of the resource groups that includes one discovery resource or a plurality of discovery resources that can be used for transmitting the discovery signal from among the one or more resource groups.
A discovery resource selection method executed by a user apparatus configured to perform transmission of a discovery signal by radio, comprising:
- determining a resource group pattern that includes one or more resource groups for transmitting the discovery signal, to be used by the user apparatus based on information transmitted from a base station;
- determining one of the resource groups including one discovery resource or a plurality of discovery resources that can be used for transmitting the discovery signal from among the one or more resource groups;
- and
- selecting a discovery resource to be used for transmitting the discovery signal from among the determined resource group.
