Power control in a local network node (LNN)
First Claim
1. A local network node for providing user equipment with a local connection to a mobile network, the mobile network comprising one or more cells overlapping a coverage area of the local network node, the local network node comprising:
- a processor configured to receive, from the user equipment one or more parameters related to a power of a downlink between the user equipment and the local network node, the power having been measured by the user equipment at a plurality of locations within a desired coverage area of the local network node; and
a measurement processor for determining a transmit power for the downlink between the local network node and the user equipment based on the one or more parameters related to the power of the downlink between the user equipment and the local network node, an average of values of power of one or more received signal codes measured at the plurality of locations, and a minimum required power for a correct reception of a downlink signal at the user equipment.

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.
