Systems and methods for using code space in spread-spectrum communications

An apparatus, comprising:

• a processor configured to:
• receive traffic channel data associated with a first traffic channel, wherein the traffic channel data includes a first set of symbols and a second set of symbols;
• cover the first set of symbols with a first spreading code of a first length to generate a first covered symbol stream;
• cover the second set of symbols with a second spreading code of a second length to generate a second covered symbol stream, wherein the second length is different from the first length;
• and
• combine the first covered symbol stream and the second covered symbol stream into a combined stream;
• and
• a transmitter configured to transmit the combined stream via a wireless communication channel.

An apparatus, comprising:

• means for receiving traffic channel data associated with a first traffic channel, wherein the traffic channel data includes a first set of symbols and a second set of symbols;
• means for covering the first set of symbols with a first spreading code of a first length to generate a first covered symbol stream;
• means for covering the second set of symbols with a second spreading code of a second length to generate a second covered symbol stream, wherein the second length is different from the first length;
• means for combining the first covered symbol stream and the second covered symbol stream into a combined stream;
• and
• means for transmitting the combined stream via a wireless communication channel.

A computer readable tangible medium comprising instructions that, when executed by a processor, cause the processor to:

• receive traffic channel data associated with a first traffic channel, wherein the traffic channel data includes a first set of symbols and a second set of symbols;
• cover the first set of symbols with a first spreading code of a first length to generate a first covered symbol stream;
• cover the second set of symbols with a second spreading code of a second length to generate a second covered symbol stream, wherein the second length is different from the first length;
• combine the first covered symbol stream and the second covered symbol stream into a combined stream;
• and
• transmit the combined stream via a wireless communication channel.

A method, comprising:

• receiving a combined stream of traffic channel data associated with a traffic channel;
• demultiplexing the combined stream of traffic channel data into a first covered symbol stream and a second covered symbol stream, wherein the first covered symbol stream is covered with a first spreading code of a first length, and wherein the second covered symbol stream is covered with a second spreading code of a second length that is different from the first length;
• decoding the first covered symbol stream into a first set of symbols using the first spreading code at a processor;
• and
• decoding the second covered symbol stream into a second set of symbols using the second spreading code at the processor.
