VERSATILE CHANNEL SELECTION PROCEDURE FOR WIRELESS NETWORK
First Claim
1. A method for selecting a frequency block for radio communications, the method comprising in a first node of a wireless network:
- determining a first value representing a lowest noise level of a radio channel at the first node or at a second node in a first frequency block;
calculating a first metric representing a ratio between a first desired signal strength and the first value, wherein the first metric represents the highest potential signal-to-noise ratio in the first frequency block;
determining a second value representing a lowest noise level of a radio channel at the first node or at the second node in a second frequency block;
calculating a second metric representing a ratio between a second desired signal strength and the second value, wherein the second metric represents the highest potential signal-to-noise ratio in the second frequency block;
selecting, on the basis of at least the first and second metric and amongst a set of frequency blocks comprising at least the first and second frequency block, a frequency block for transmission of a message between the first node and the second node;
indicating a sub-band of the selected frequency block for the message; and
causing transmission of the message on the indicated sub-band of the selected frequency block.

Abstract
A method of selecting a frequency block includes determining a first value representing a lowest noise level of a radio channel at a first or second node, calculating a first metric representing a ratio between a first desired signal strength and the first value, determining a second value representing a lowest noise level of a radio channel at the first or second nodes, calculating a second metric representing a ratio between a second desired signal strength and the second value, selecting, on the basis of at least the first and second metrics and amongst a set of frequency blocks including at least the first and second frequency blocks, a frequency block for transmission of a message between the first and second nodes, indicating a sub-band of the selected frequency block, and causing transmission of the message on the indicated sub-band.
