Abstract

A wireless transmission system for multimedia information having plural layers includes a base station (BTS) and a mobile station (MS) that can select which layers to transmit based on reported channel conditions, mobile location, and/or forward error correction (FEC) used for a particular layer. A respective FEC rate and/or power level can be dynamically established for each layer by a mobile station dependent on available bandwidth and/or reception and decoding capability of the BTS.

Claims

1. A method for transmission of multimedia data from a mobile station comprising:

receiving at a mobile station (MS), from at least one base station (BTS), information representing at least one operational parameter associated with the multimedia data, wherein operational parameters may comprise an error rate, a channel condition, an MS location, a mobile station limitation, a user priority, a content priority, a billing plan, and a forward error correction (FEC) rate;

dynamically establishing, at the MS, at least one characteristic of a base layer and/or an enhancement layer of the multimedia data based on the received operational parameter information; and

selecting which of the base and/or enhancement layers to be transmitted to the BTS based on the received operational parameter information, and selecting a transmit power level and/or a FEC rate for each layer to be transmitted based on the received operational parameter information in order to save power.

2. The method of claim 1, wherein the step of dynamically establishing includes establishing a base forward error correction rate for the base layer and an enhancement forward error correction rate for the at least one enhancement layer.

8. The method of claim 1, wherein the information representing the at least one actual operational parameter associated with the multimedia data is indicative of a redundancy or power level of a layer of the multimedia data sufficient for the BTS to reliably receive the layer.

3. An apparatus for transmission of multimedia data from a mobile station comprising:

means for receiving at a mobile station (MS), from at least one base station (BTS), information representing at least one operational parameter associated with the multimedia data wherein operational parameters may comprise an error rate, a channel condition, an MS location, a mobile station limitation, a user priority, a content priority, a billing plan, and a forward error correction (FEC) rate;

means for dynamically establishing, at the MS, at least one characteristic a base layer and/or an enhancement layer of the multimedia data based on the received operational parameter information;

and means for selecting which of the base and/or enhancement layers to be transmitted to the BTS based on the received operational parameter information, and selecting a transmit power level and/or a FEC rate for each layer to be transmitted based on the received operational parameter information in order to save bower.

9. The apparatus of claim 3, wherein the information representing the at least one actual operational parameter associated with the multimedia data is indicative of a redundancy or power level of a layer of the multimedia data sufficient for the BTS to reliably receive the layer.

11. The apparatus of claim 3, wherein the means for dynamically establishing includes means for establishing a base forward error correction rate for the base layer and means for establishing a forward error correction rate for the at least one enhancement layer.

4. A non-transitory computer-readable medium including computer-operable instructions for transmission of multimedia data comprising:

instructions for receiving at a mobile station (MS), from at least one base station (BTS), information representing at least one actual operational parameter associated with the multimedia data wherein operational parameters may comprise an error rate, a channel condition, an MS location, a mobile station limitation, a user priority, a content priority, a billing plan, and a forward error correction (FEC) rate;

instructions for dynamically establishing at the MS at least one characteristic of a base and/or enhancement layer of the multimedia data based on the received operational parameter information; and

instructions for selecting which of the base and/or enhancement layers to be transmitted to the BTS based on the received operational parameter information, and selecting a transmit power level and/or a FEC rate for each layer to be transmitted based on the received operational parameter information in order to save power.

5. The non-transitory computer readable medium of claim 4, wherein the instructions for dynamically establishing at the MS at least one characteristic of at least one layer of the multimedia data based at least in part on the received information include instructions for establishing a base forward error correction rate for the base layer and an enhancement forward error correction rate for the at least one enhancement layer.

10. The non-transitory computer-readable medium of claim 4, wherein the information representing the at least one actual operational parameter associated with the multimedia data is indicative of a redundancy or power level of a layer of the multimedia data sufficient for the BTS to reliably receive the layer.

6. A processing apparatus capable of performing logic operations for transmission of multimedia data in at least one mobile station that results in power savings on a mobile device, by establishing a power for each layer transmitted instead of establishing FEC rate layer by layer characterized by at least a base layer and at least one enhancement layer stored thereon, comprising:

a processor;

a memory coupled to the processor,

wherein the processor is configured with software instructions to perform logic operations comprising;

receiving at a mobile station (MS), from at least one base station (BTS), information representing at least one operational parameter associated with the multimedia data, wherein operational parameters include;

an error rate, a channel condition, an MS location, a mobile station limitation, a user priority, a content priority, a billing plan, and a forward error correction (FEC) rate;

dynamically establishing, at the MS, at least one characteristic of a base layer and/or an enhancement layer of the multimedia data based on the received operational parameter information; and

selecting which of the base and/or enhancement layers to be transmitted to the BTS based on the received operational parameter information, and selecting a transmit power level and/or a FEC rate for each layer to be transmitted based on the received operational parameter information in order to save power.

7. The processing apparatus of claim 6, wherein the processor is configured with software instructions to perform logic operations comprising:

establishing a base forward error correction rate for the base layer and an enhancement forward error correction rate for the at least one enhancement layer.

12. An apparatus for transmission of multimedia data from a mobile, comprising:

a receiver for receiving at a mobile station (MS), from at least one base station (BTS), information representing at least one operational parameter associated with the multimedia data wherein operational parameters may comprise an error rate, a channel condition, an MS location, a mobile station limitation, a user priority, a content priority, a billing plan, and a forward error correction (FEC) rate;

a processor for dynamically establishing, at the MS, at least one characteristic a base layer and/or an enhancement layer of the multimedia data based on the received operational parameter information; and

a selector for selecting which of the base and/or enhancement layers to be transmitted to the BTS based on the received operational parameter information, and selecting a transmit power level and/or a FEC rate for each layer to be transmitted based on the received operational parameter information in order to save power.

13. The apparatus of claim 12, wherein the information representing the at least one actual operational parameter associated with the multimedia data is indicative of a redundancy or power level of a layer of the multimedia data sufficient for the BTS to reliably receive the layer.
