System and method for allocating power
First Claim
1. A system for allocating a power budget between at least two communication services comprising:
- at least one receiving-station being, in the aggregate, operable to receive at least two different communication services; and
, a transmitting-station for transmitting each of said services to at least one of said receiving-stations using a portion of said power budget, said portions being allocated according to an allocation criteria such that said power budget is substantially consumed.

Abstract
The present invention provides a novel system, method and apparatus for allocating power between at least two communication services that share a common power output limit. Two communication services particularly suited for the present invention are voice services and data services transmitted on the downlink of a wireless network. An embodiment of the method includes determining the actual consumption of power on the voice channels of the wireless network during a given time period, and allocating substantially the same amount of power to the voice channels for the next time period, thus allowing for the allocation of the remaining amount of power to the data services, and thereby allowing, for example, increased modulation of the data services and thereby improve overall rates of data transfer and/or reliability of data transmission. Another embodiment of the method includes determining the power requirements for at least one communication service during the current time period; and, allocating a portion of the power budget to each communication services based on the determination.

17. A method of allocating a power budget between communication services comprising the steps of:
-
predicting power requirements for at least one communication service during a future time period; and
,allocating a portion of said power budget to each of said communication services based on said prediction.

19. A method of allocating a power budget between communication services comprising the steps of:
-
a. for an initial time period, allocating said power budget between a plurality of communication services over a wireless link according to a predefined allocation;
b. for a current time period, establishing said communication services according to said allocation;
c. for said current time period, determining actual power consumption of at least one of said services;
d. for a future time period, allocating at least an equivalent amount of power as said actual power consumption determined at step (iii) to said at least one of said services;
e. for said future time period, allocating a remaining amount of power to a remainder of said services, said remaining amount being an amount that was unallocated to said at least one of said services; and
,f. repeating steps (ii)-(v) for said future time period.

20. A system for allocating a power budget between at least two services comprising:
-
a first subscriber station operable to receive at least a voice service;
an additional subscriber station operable to receive at least a data service;
a base station for transmitting said voice service to said first subscriber-station using a portion of said power budget while transmitting said data service to said additional subscriber station using a remainder of said power budget, said portion allocated based on an actual amount of power consumed during a previous time period.

21. A subscriber station comprising:
-
a receiver for a signaling channel, a voice channel and a data channel;
processing means connected to said receiver for adjusting demodulation and forward error correction rates of packets received over said voice channel and said data channel during successive time periods, said adjusting based on instructions received over said signaling channel that correspond to power allocations made by a base station transmitting said channels.

22. A base station comprising:
-
a gateway for receiving voice packets and data packets from a network;
a processing unit for allocating a portion of a power budget for smiting voice packets during a current time period based on actual power consumed for transmitting voice packets during a previous time period, said processing unit for further allocating a remainder of said power budget for transmitting data packets during said current time period; and
,a transmitter for transmitting said packets to intended subscriber stations via a downlink according to said allocations.
