Method and system of setting transmitter power levels
First Claim
1. A network node for providing user equipment with a connection to a mobile network, the mobile network comprising one or more cells overlapping a coverage area of the network node, the network node comprising:
- a processing system to perform operations comprising;
receiving, from the user equipment, one or more parameters related to interference on a downlink between the user equipment and the network node, the interference resulting at least partly from overlapping cells of the mobile network and other competing network nodes, the one or more parameters corresponding to a signal power at the user equipment for one or more of the overlapping cells and the other competing local network nodes; and
determining a transmit power for the downlink based on the one or more parameters.

Abstract
The invention relates to a method and system of setting transmitter power levels, particularly in a Local Network Node transmitter, providing a pico cell for private use. A User Equipment (UE) is used to make measurements of the transmission link properties, such as downlink power and round trip time. Based on the measurements made at one or a plurality of locations, the power of the Local Network Node can be determined such that interference is minimized with any overlying cells of a macro-network. Call handovers between the UE and the cell of a macro network can also be arranged based on properties measure by the UE.
