• wherein the one of the plurality of descriptions of content comprises a combination of a first portion of the content encoded to a second quality and a second portion of the content encoded to a first quality, the second quality lesser than the first quality, wherein each of the plurality of descriptions is configured such that reception of that description alone enables a version of the content to be decoded as a whole.

A method of wireless communication, comprising:

• receiving a first description of content of a plurality of descriptions from a content server;
• receiving a second description of the content of the plurality of descriptions from a helper node proximate to the content server;
• and
• selectively combining at least a portion of the first description with at least a portion of the second description to obtain the content having a higher quality, as a whole, than either the first description or the second description taken alone,
• wherein the first description comprises a combination of a first portion of the content encoded to a first quality and a second portion of the content encoded to a second quality, the second quality lesser than the first quality, and wherein each of the plurality of descriptions is configured such that reception of that description alone enables a version of the content to be decoded as a whole.

A computer program product for sending content, comprising:

• and
• sharing a second one of the plurality of descriptions with a first helper node capable of transmitting the second one of the plurality of descriptions on a second uplink,
• wherein the code for generating the plurality of descriptions comprises code for encoding a first portion of the content to a first quality, encoding a second portion of the content to a second quality, the second quality lesser than the first quality, and combining the first portion encoded to the first quality and the second portion encoded to the second quality to provide the first one of the plurality of descriptions, wherein each of the plurality of descriptions is configured such that reception of that description alone enables a version of the content to be decoded as a whole.
