Abstract
A method and apparatus are provided for managing transmission resources in a cellular communication network having a plurality of cells each associated to a base station. The network includes at least two radio-communication terminals, a list of available transport formats or authorized list being associated with each of the terminals. The method includes optimizing frequency resources used by the terminals present in the network, and includes the following sub-steps: selecting a transport format specific for each terminal from a shortened list of transport formats, and allocating a frequency band to each terminal and having a size based on the selected transport format.

A method for managing transmission resources in a cellular communications network comprising a plurality of cells, each associated with a base station, the network comprising at least two radio communications terminals, an authorized list of available transport formats being associated with each of the terminals, wherein the method comprises:
- creating a shortened list for each of said terminals by implementing the following algorithm:
- initializing an empty shortened list;
- and
- scanning the authorized list of available transport formats associated with said terminal and for each transport format:
- if, in said authorized list, there is a transport format for transporting a number of encoded information bits smaller than or equal to the number of encoded information bits transported by said transport format and having a spectral efficiency greater than that of said transport format,
- then passing to the next transport format in said authorized list,
- else, adding said transport format to said shortened list and passing to the next transport format in said authorized list;
- and
- optimizing frequency resources used by said terminals present in said network, comprising sub-steps of:
- selecting a specific transport format for each of said terminals from the shortened list of transport formats, and
- allocating a frequency band to each of said terminals, dimensioned as a function of the selected transport format.
A radio communications terminal designed to be implemented in a cellular communications network comprising a plurality of cells, each associated with a base station, an authorized list of available transport formats being associated with said terminal, wherein said terminal comprises:
- means for determining a shortened list for each of said terminals by implementing the following algorithm:
- initializing an empty shortened list;
- and
- scanning the authorized list of available transport formats associated with said terminal and for each transport format:
- if, in said authorized list, there is a transport format for transporting a number of encoded information bits smaller than or equal to the number of encoded information bits transported by said transport format and having a spectral efficiency greater than that of said transport format,
- then passing to the next transport format in said authorized list,
- else, adding said transport format to said shortened list and passing to the next transport format in said authorized list;
- and
- means for optimizing frequency resources used by said terminal present in said network, said means comprising:
- means for selecting a specific transport format for the terminal from the shortened list of transport formats, and
- means for allocating a frequency band to said terminal, dimensioned as a function of the selected transport format.
A base station designed to be implemented in a cellular communications network comprising a plurality of cells, the network comprising at least two radio communications terminals, an authorized list of available transport formats being associated with each of said terminals, wherein said base station comprises:

- initializing an empty shortened list;
- and
- scanning the authorized list of available transport formats associated with said terminal and for each transport format:
- if, in said authorized list, there is a transport format for transporting a number of encoded information bits smaller than or equal to the number of encoded information bits transported by said transport format and having a spectral efficiency greater than that of said transport format,
- then passing to the next transport format in said authorized list,
- else, adding said transport format to said shortened list and passing to the next transport format in said authorized list;
- and
- means for optimizing frequency resources used by said terminals present in said network, the means comprising:
- means for selecting a specific transport format for each of the terminals from the shortened list of transport formats, and
- means for allocating a frequency band to at least one of said terminals, dimensioned as a function of the selected transport format.
A computer program product recorded on a non-transitory computer-readable medium and executable by a processor, the program comprising program code instructions for implementation of a method for managing transmission resources in a cellular communications network comprising a plurality of cells each associated with a base station, the network comprising at least two radio communications terminals, an authorized list of available transport formats being associated with each of the terminals, wherein the method comprises:
- creating a shortened list for each of said terminals by implementing the following algorithm:
- initializing an empty shortened list;
- and
- scanning the authorized list of available transport formats associated with said terminal and for each transport format:
- if, in said authorized list, there is a transport format for transporting a number of encoded information bits smaller than or equal to the number of encoded information bits transported by said transport format and having a spectral efficiency greater than that of said transport format,
- then passing to the next transport format in said authorized list,
- else, adding said transport format to said shortened list and passing to the next transport format in said authorized list;
- and
- optimizing frequency resources used by said terminals present in said network, comprising sub-steps of:
- selecting a specific transport format for each of said terminals from the shortened list of transport formats, and
- allocating a frequency band to each of said terminals, dimensioned as a function of the selected transport format.
