Abstract
A wireless cellular network includes a plurality of cells, each cell including a base station for serving one or more mobile users. For controlling an operation within a cell of the wireless cellular network, a fuzzy logic is used. The input variables for the fuzzy logic include input variables determined on the basis of information only locally available in the cell.

A method for controlling operation within a cell of a wireless cellular network, the wireless cellular network comprising a plurality of cells, each cell comprising a base station for serving one or more mobile users, the method comprising:
- controlling, by a base station of the cell, an operation within the cell using a fuzzy logic, wherein input variables for the fuzzy logic comprise input variables determined on the basis of information only locally available in the cell,
- wherein the operation to be controlled within the cell comprises resource and power allocation,
- wherein
- resource and power allocation to a user served by the base station of a cell is performed on the basis of interference information about an interference incident from one or more neighboring cells, the input variables for the fuzzy logic being determined on the basis of interference information only locally available in the cell, and
- the base station allocates resource blocks such that a desired signal to the user is acquired, the interference incident from one or more neighboring cells is reduced or minimized, and a rate requirement of the user in the cell is fulfilled, wherein the locally available information comprise a necessitated rate of the user;
- a quality or strength of the desired signal;
- a level of interference incident on the resource blocks;
- and a frequency-selective fading profile.
A base station of a cell of a wireless cellular network, the wireless cellular network comprising a plurality of cells, each cell comprising a base station for serving one or more mobile stations, comprising:
- a fuzzy logic for controlling an operation within the cell using the fuzzy logic,
- wherein input variables for the fuzzy logic comprise input variables determined on the basis of information only locally available in the cell,
- wherein the operation to be controlled within the cell comprises resource and power allocation,
- wherein
- resource and power allocation to a user served by the base station of a cell is performed on the basis of interference information about an interference incident from one or more neighboring cells, the input variables for the fuzzy logic being determined on the basis of interference information only locally available in the cell, and
- the base station allocates resource blocks such that a desired signal to the user is acquired, the interference incident from one or more neighboring cells is reduced or minimized, and a rate requirement of the user in the cell is fulfilled, wherein the locally available information comprise a necessitated rate of the user;
- a quality or strength of the desired signal;
- a level of interference incident on the resource blocks;
- and a frequency-selective fading profile.
