Wireless communication base station device and total transmission power regulating method
摘要:
Disclosed are a wireless communication base station and a total transmission power regulating method that reduce interference to macrocell users near a femtocell and interference to neighboring femtocell users near the femtocell in a balanced manner, while ensuring throughput of the femtocell users. A reception power measuring unit (214) measures the reception power of a CPICH. A cell type discriminating unit (216) judges whether the received signal is a signal from a macro base station or a signal from a femto base station. When a signal from a macro base station is received, a total downlink transmission power setting unit (217) executes a first-stage interference regulation based on the strongest CPICH reception power value and calculates a tentative value for the total downlink transmission power of a femto base station (110). When a signal from a peripheral femto base station is received, the total downlink transmission power setting unit (217) executes a second-stage interference regulation within a fixed power regulation range for the second-stage interference regulation based on the strongest CPICH reception power value, and calculates a final total downlink transmission power value.
