RADIO COMMUNICATION APPARATUS AND TRANSMISSION POWER CONTROL METHOD

摘要

A radio communication apparatus and transmission power control method are disclosed, which can maintain communication with handsets while avoiding an increase in radio interference to another radio communication system as much as possible when radio communication is performed with one or more handsets. The handset transmits a communication start request signal to a base unit. Upon verifying the reception of the communication start request, the base unit measures the RSSI level of the communication start request signal transmitted from the handset, determines a transmission power value based on a power control table that has been updated with the measured RSSI level, and controls the transmission power of a control signal transmitted to the handset.

主权项

1. A radio communication apparatus comprising:
a level measurement section that measures a reception level of a predetermined signal transmitted from one or more handsets; a storage section that stores the reception level for each of the handsets; a transmission power control section that determines a transmission power value of a control signal transmitted to all the handsets, in accordance with a minimum value of the stored reception level; and a transmitting section that transmits, to all the handsets, the control signal using the transmission power value determined by the transmission power control section.
