Abstract:
1. A radio base station apparatus comprising a processor and a memory, the processor comprising: a multiple point reception processing section configured to apply uplink coordinated multiple point reception to a mobile terminal apparatus when a difference (PL a transmission power control section configured to perform transmission power control for application of uplink coordinated multiple point reception when the uplink coordinated multiple point reception is applied, while performing transmission power control for non-application of the uplink coordinated multiple point reception when the uplink coordinated multiple point reception is not applied, wherein the radio base station apparatus performs fractional transmission power control, the transmission power control section generates an attenuation coefficient for application of uplink coordinated multiple point reception, and an attenuation coefficient for non-application of uplink coordinated multiple point reception, and the transmission power control section uses a pass loss difference obtained using a pass loss calculated from the first pass loss and a pass loss between the second radio base station apparatus and the mobile terminal apparatus, as a substitute for the first pass loss, as a pass loss for application of uplink coordinated multiple point reception.
