Nodes and method for power control
First Claim
1. A controlling node for User Equipments (UEs) in a cell in a cellular communications system, wherein the controlling node is arranged to:
- generate and transmit control commands to the UEs in said cell to control their output power levels;
generate said control commands using, selectively, one of at least a first and a second power control scheme, where the first power control scheme is a signal quality based power control scheme and the second power control scheme is a signal strength based power control scheme;
receive a command from the network controlling node, the command regarding which of said power control schemes the controlling node should use in generating said control commands to a particular UEreceive, from a network controlling node, an identifier of the power control schemes that the other controlling node is deploying; and
determine at least one of the first and second power control schemestransmit information to said network controlling node for use in the network controlling node'"'"'s selection of which of said power control schemes should be used by the controlling node for a particular UE, the information including one or more of;
a target received signal level in the cell of the UE;
assigned resources in the cell of the UE; and
characteristics of the radio environment for the UE in question.

Abstract
A controlling node (210) for UEs (115) in a cell in a communications system (200), arranged to generate (255) and transmit (230, 235) control commands to the UEs regarding their output power level, and to generate those control commands using either at least a first or a second power control scheme. In embodiments, the first power control scheme is a signal quality based power control scheme and the second power control scheme is a signal strength based power control scheme. In embodiments, the controlling node (210) is arranged to receive (230, 240) from a network controlling node (205) information regarding the capabilities of at least one other controlling node (220) in the cellular communications system (200) with respect to which power control scheme or schemes that the other controlling node (220) is arranged to use.
