Abstract
To avoid a reduction in a peak rate in an uplink as much as possible. A radio base station eNB according to the present invention includes a scheduling unit 12 configured to assign a PUCCH resource, a PUSCH resource, and a PRACH resource to a mobile station UE in a cell subordinate to the radio base station eNB, wherein, when the number of mobile stations UEs in the cell is 1, the scheduling unit 12 is configured to use at least one of the PUCCH resource and the PRACH resource as the PUSCH resource.
Claims6
A radio base station comprising:
- a scheduling unit configured to assign a resource for a physical uplink control channel for transmitting an uplink control signal, a resource for a physical uplink shared channel for transmitting an uplink data signal, and a resource for a physical random access channel to a mobile station in a cell subordinate to the radio base station, wherein,
- when the number of mobile stations in the cell is 1, the scheduling unit is configured to use at least one of the resource for the physical uplink control channel and the resource for the physical random access channel as the resource for the physical uplink shared channel.
A mobile communication method comprising:
- a step of assigning, by a radio base station, a resource for a physical uplink control channel for transmitting an uplink control signal, a resource for a physical uplink shared channel for transmitting an uplink data signal, and a resource for a physical random access channel to a mobile station in a cell subordinate to the radio base station,
- wherein, in the step, when the number of mobile stations in the cell is 1, the radio base station uses at least one of the resource for the physical uplink control channel and the resource for the physical random access channel as the resource for the physical uplink shared channel.
