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.

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.
