Abstract

A method comprises selecting, for at least a part of a set of data to be transmitted to a user equipment in cell, a bit rate, said bit rate being selected in dependence on radio conditions associated with said user equipment in said cell.

First claim

The invention claimed is:

1. A method comprising:
selecting, for at least a part of a set of data to be transmitted to a user equipment in a cell, a bit rate, wherein said bit rate is selected in dependence on radio conditions associated with said user equipment in said cell,
wherein said selecting comprises determining for a candidate bit rate including the selected bit rate, an associated required power,
wherein said determining comprises determining said associated required power depending on radio condition information,
wherein said radio condition information comprises interference dependent information, and
wherein said interference dependent information comprises an average bit rate achievable by said user equipment.

2. A method comprising:
selecting, for at least a part of a set of data to be transmitted to a user equipment in a cell, a bit rate, wherein said bit rate is selected in dependence on radio conditions associated with said user equipment in said cell,
wherein said selecting comprises determining for said user equipment a candidate maximum power,
wherein said determining comprises determining said candidate maximum power in dependence on one or more parameters, and
wherein said one or more parameters comprise one or more locations of said user equipment in said cell, subscription of said user equipment, a type of the user equipment, a type of service required by the user equipment, and signal strength.

3. A method comprising:
selecting, for at least a part of a set of data to be transmitted to a user equipment in a cell, a bit rate, wherein said bit rate is selected in dependence on radio conditions associated with said user equipment in said cell,
wherein said selecting comprises determining for said user equipment a candidate maximum power,
wherein said determining comprises determining said candidate maximum power in dependence on one or more parameters, and
wherein a value associated with said parameter is selected for each of a plurality of user equipment including the user equipment such that a total of each of said values satisfies a condition.

4. The method as claimed in claim 3 , wherein each value divided by said total of each said values determines a respective share of the user equipment of a total available power.

5. The method as claimed in claim 4 , wherein said total available power is dependent on loading in said cell.

6. A method comprising:
selecting, for at least a part of a set of data to be transmitted to a user equipment in a cell, a bit rate, wherein said bit rate is selected in dependence on radio conditions associated with said user equipment in said cell,
wherein said selecting comprises determining for a candidate bit rate including the selected bit rate, an associated required power, and
wherein the method further comprises comparing information on said associated required power and a candidate maximum power to determine if said candidate bit rate is supportable.

7. A method comprising:
selecting, for at least a part of a set of data to be transmitted to a user equipment in a cell, a bit rate, wherein said bit rate is selected in dependence on radio conditions associated with said user equipment in said cell; and
running at least one iterative algorithm to select a respective bit rate for a plurality of user equipment including the user equipment in the cell such that a total power associated with said respective bit rates is less than or equal to a total available power.

8. An apparatus, comprising:
at least one processor; and
at least one memory including computer code for one or more programs, the at least one memory and the computer code are configured, with the at least one processor, to cause the apparatus at least to:
select, for at least a part of a set of data to be transmitted to a user equipment in cell, a bit rate, said bit rate being selected in dependence on radio conditions associated with said user equipment in said cell;
determine for a candidate bit rate including the selected bit rate, an associated required power;
compare information on said associated required power and a candidate maximum power to determine if said candidate bit rate is supportable; and
trigger the transmission of at least a part of the set of data to the user equipment in the cell using the scheduled bit rate.

9. An apparatus, comprising:
at least one processor; and
at least one memory including computer code for one or more programs, the at least one memory and the computer code are configured, with the at least one processor, to cause the apparatus at least to:
select, for at least a part of a set of data to be transmitted to a user equipment in cell, a bit rate, wherein said bit rate is selected in dependence on radio conditions associated with said user equipment in said cell; and
run at least one iterative algorithm to select a respective bit rate for a plurality of user equipment including the user equipment in the cell such that a total power associated with said respective bit rates is less than or equal to a total available power.
