BASE STATION APPARATUS, WIRELESS COMMUNICATION SYSTEM, AND WIRELESS TRANSMISSION METHOD

摘要

Allocation of transmission power is carried out adaptively without affecting adjacent cells. There are comprised a reception part (132) that receives information from a mobile station apparatus, a transmission power determination part (125) that determines transmission power when transmitting a wireless signal to a mobile station apparatus based on the received information, an acquisition part (120) that acquires information about communication environment in each time channel or each frequency channel from the received information, a scheduling part (120) that identifies a time channel or frequency channel the relationship of which between transmission power and communication environment satisfies the condition for allocation and allocates transmission data and transmission power for transmission to a mobile station apparatus to a communication slot in the time channel or frequency channel, and a transmission part (130, 131) that transmits a wireless signal using the communication slot to which the transmission data and the determined transmission power have been allocated.
