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 base unit apparatus comprising:
a radio controller configured to measure reception levels of signals received from a plurality of handsets; a memory configured to store the reception levels of the plurality of handsets, respectively; a signal processor configured to determine a transmission power value, at which to transmit a control signal to all of the plurality of handsets, based on a minimum value of the stored reception levels of the plurality of handsets; and a transmitter configured to transmit the control signal at the determined transmission power value to all of the plurality of handsets.
