Method and apparatus for controlling transmission power of a remote unit communicating with a base unit over a common frequency channel
First Claim
1. An open loop method of controlling the power of a remote transmitted signal transmitted by a remote communication device to a base communication device in a frequency channel in a first time period, said base device transmitting to said remote device a base transmitted signal in the frequency channel in a second time period different from the first time period, said method comprising:
- receiving said base transmitted signal in the frequency channel by said remote device;
measuring the power of said base transmitted signal received by said remote device; and
controlling the transmission power of the remote transmitted signal in the frequency channel in accordance with
space="preserve" listing-type="equation">Power=A+(B-C) where A is representative of the desired power of the remote transmitted signal received by the base device;
B is representative of the power of the base transmitted signal;
C is representative of the measured power of the base transmitted signal as received by the remote device.

Abstract
In the present invention, the power of a remote transmitted signal is controlled, by a remote communication device. The remote communication device is in communication with the base communication device. The base communication device transmits to the remote device a base transmitted signal. The base transmitted signal is received by the remote device and its power is measured. The transmission power of the remote transmitted signal is controlled in accordance with
Power=A+(B-C)
where A is representative of the desired power of the remote transmitted signal received by the base device; B is representative of the power of the base transmitted signal, transmitted by the base device; and C is representative of the measured power of the base transmitted signal as received by the remote device.
