Abstract
A method is provided of controlling transmission power of a picocell base station. The method comprises the steps of the picocell base station: transmitting a signal at a first power; receiving a report from a mobile terminal that the signal is received within a predetermined quality range; dependent upon receiving said report instructing the mobile terminal to report as to the number of neighboring macrocells detected by the mobile terminal; and controlling the transmission power of a further signal dependent upon said number.

A method of controlling transmission power of a picocell base station,
- the method comprising the steps of the picocell base station:
- transmitting a signal at a first power;
- receiving a report from a mobile terminal that the signal is received within a predetermined quality range;
- dependent upon receiving said report instructing the mobile terminal to report as to the number of neighboring macrocells detected by the mobile terminal;
- and
- controlling the transmission power of a further signal from the picocell base station dependent upon said number.
A picocell base station comprising a transmitter, a receiver, a first controller and a second controller,
- the transmitter being configured to transmit a signal at a first power,
- the receiver being configured to receive a report from a mobile terminal that the signal received by the mobile terminal is within a predetermined quality range,
- the first controller being configured to, dependent upon receiving said report, instruct the mobile terminal to report as to the number of neighboring macrocells detected by the mobile terminal,
- the second controller being configured to control the transmission power of a further signal from the picocell base station dependent upon said number.
