1. A method comprising:
- transmitting a first radio signal from a first radio station to a second radio station, the first signal being sent according to a first power assignment and a first spatial weight vector;
receiving from the second station a quality of the first signal;
determining at the first station a second power assignment based on the received quality of the first signal; and
transmitting a second radio signal from the first station to the second station using the second power assignment.

Abstract
A method for power control with signal quality estimation for smart antenna communications system is described. The method, for example, starts with a transmit power assignment. Receive weight vector determination is carried out with this assigned transmit power, and the new weights used. An estimate of the resulting received signal quality is obtained and used for another power adjustment.

9. A radio station comprising:
-
a transmitter to transmit a first radio signal from the radio station to a second radio station, the first signal being sent according to a first power assignment and a first spatial weight vector; a receiver to receive from the second radio station a quality of the first signal; and a signal processor to determine a second power assignment based on the received quality of the first signal, wherein the transmitter is further operable to transmit a second radio signal from the first radio station to the second radio station using the second power assignment. - View Dependent Claims (10, 11, 12)
