Method for reporting uplink load measurements
View Patent ↗The present invention provides a method for reporting load measurements. The method may include providing information indicative of a first load associated with at least one first channel type to a first scheduling unit. The first load represents a difference between a second load associated with at least one second channel type and a third load.
1. A method, comprising:
determining, at a base station, a first load on at least one first uplink channel type based on a ratio of a measured received total wideband power and an estimated background noise received total wideband power and based on a sum of a product of an energy per chip to interference power ratio and a power ratio of uplink and downlink channels, the sum being taken over users that are scheduled by the base station, wherein load control for said at least one first uplink channel type is performed in a radio network controller, the first load representing a difference between a second load on at least one second uplink channel type and a total uplink load;
providing, from the base station to the radio network controller, information indicative of the first load so that the radio network controller can perform at least one of admission control or congestion control for said at least one first uplink channel type based on the first load; and
performing, at the base station, at least one of admission control or congestion control for said at least one second uplink channel type based on the second load.
2. A method, comprising:
determining, at a base station, a first load on at least one first uplink channel type based on a ratio of a sum of a physical channel measurement of a received signal code power for a user to a received total wideband power, the sum being taken over users that are scheduled by the radio network controller, wherein load control for said at least one first uplink channel type is performed in a radio network controller, the first load representing a difference between a second load on at least one second uplink channel type and a total uplink load;
providing, from the base station to the radio network controller, information indicative of the first load so that the radio network controller can perform at least one of admission control or congestion control for said at least one first uplink channel type based on the first load; and
performing, at the base station, at least one of admission control or congestion control for said at least one second uplink channel type based on the second load.
3. The method of claim 1 , comprising determining the information indicative of the first load by applying at least one filter to the determined first load.
4. The method of claims 1 or 2 , wherein providing the information indicative of the first load comprises providing the information indicative of the first load based on at least one of a reporting schedule, a threshold, and a request for the information indicative of the first load.
5. The method of claims 1 or 2 , wherein providing the information indicative of the first load comprises providing the information indicative of the first load in a measurement report message that is transmitted from the base station to the radio network controller.
6. The method of claims 1 or 2 , comprising receiving, at the base station and from the radio network controller, at least one load control parameter determined by the load control unit in the radio network controller in response to providing the information indicative of the first load.
7. The method of claims 1 or 2 , wherein providing said information indicative of the first load associated with said at least one first uplink channel type to the load control unit comprises providing information indicative of a first load associated with a legacy dedicated channel to the load control unit in the radio network controller.
8. The method of claims 1 or 2 , wherein providing information indicative of the first load comprises providing information indicative of a difference between a second load associated with at least one enhanced dedicated channel and the total uplink load.
9. The method of claims 1 or 2 , comprising scheduling, at the base station, users for said at least one second uplink channel type based upon the second load.
10. The method of claims 1 or 2 , wherein said at least one first uplink channel type comprises at least one unscheduled legacy uplink channel type, and wherein said at least one second uplink channel type comprises at least one scheduled uplink channel type.
11. A method, comprising:
receiving, at a radio network controller and from at least one base station, information indicative of a first load associated with at least one first uplink channel type, wherein said information indicating the first load is determined based on a ratio of a measured received total wideband power and an estimated background noise received total wideband power and based on a sum of a product of an energy per chip to interference power ratio and a power ratio of uplink and downlink channels, the sum being taken over users that are scheduled by the base station, the first load being determined by said at least one base station, and the first load representing a difference between a second load associated with at least one second uplink channel type and a total uplink load; and
performing, at the radio network controller, at least one of admission control or congestion control for said at least one first uplink channel type based on the first load, and wherein the base station performs at least one of admission control or congestion control for said at least one second uplink channel type based on the second load.
12. A method, comprising:
receiving, at a radio network controller and from at least one base station, information indicative of a first load associated with at least one first uplink channel type, wherein said information indicating the first load is determined based on a ratio of a sum of a physical channel measurement of a received signal code power for a user to a received total wideband power, the sum being taken over users that are scheduled by the radio network controller, the first load being determined by said at least one base station, and the first load representing a difference between a second load associated with at least one second uplink channel type and a total uplink load; and
performing, at the radio network controller, at least one of admission control or congestion control for said at least one first uplink channel type based on the first load, and wherein the base station performs at least one of admission control or congestion control for said at least one second uplink channel type based on the second load.
13. The method of claims 11 or 12 , wherein receiving the information indicative of the first load comprises receiving the information indicative of the first load based on at least one of a reporting schedule, a threshold, and the request for the information indicative of the first load.
14. The method of claims 11 or 12 , wherein receiving the information indicative of the first load comprises receiving the information indicative of the first load in a measurement report message transmitted from said at least one base station to the radio network controller.
15. The method of claims 11 or 12 , comprising performing, at the load control unit in the radio network controller, admission control or congestion control based on the information indicative of the first load.
16. The method of claim 15 , comprising providing, from the radio network controller to said at least one base station, at least one load control parameter in response to performing admission control or congestion control based on the information indicative of the first load.
17. The method of claims 11 or 12 , wherein receiving said information indicative of the first load associated with said at least one first uplink channel type comprises receiving, from said at least one base station, information indicative of a first load associated with a legacy dedicated channel.
18. The method of claims 11 or 12 , wherein receiving information indicative of the first load comprises receiving information indicative of a difference between a second load associated with at least one enhanced dedicated channel and the total uplink load.
19. The method of claims 11 or 12 , wherein said at least one first uplink channel type comprises at least one unscheduled legacy uplink channel type, and wherein said at least one second channel type comprises at least one scheduled uplink channel type.
