Abstract
A method is provided of adjusting transmission power of pilot signals from a picocell base station for radio communications to a user terminal in radio connection with the picocell base station. The method comprises: the base station sending a signal at a first signal power; the user terminal measuring received signal level and sending an information signal indicating received signal level; and the base station adjusting its pilot signal power dependent upon said received signal level indicated in the information signal.

A method of adjusting transmission power of pilot signals from a picocell base station for radio communications to a user terminal in radio connection with the picocell base station,
- the method comprising:
- the base station sending a signal at a first signal power;
- the user terminal measuring received signal level and sending to the base station an information signal indicating the received signal level;
- and
- the base station adjusting its pilot signal power dependent upon said received signal level indicated in said information signal.
A picocell base station,
- the base station comprising:
- a transmitter operative to send a signal at a first power;
- a receiver operative to receive an indication of received signal level as measured at a user terminal;
- a processor operative to decode the indication of the received signal level;
- a pilot power control stage operative to adjust, dependent upon the indication of the received signal level, the power of a pilot signal to be transmitted;
- and
- the transmitter being operative to transmit the pilot signal.
