Claims
- 1. A method for transferring data over a direct sequence-code division multiple access physical channel, comprising the steps of:transmitting a data field including said data over said direct sequence-code division multiple access physical channel during a predefined duration; simultaneously transmitting a signature field over said direct sequence-code division multiple access physical channel during said predefined duration, a signature included in said signature field spread by a first predetermined code, and said data included in said data field spread by a second code associated with said signature; and said signature field also functions as a pilot signal by providing additional energy in the form of known modulated symbols.
- 2. The method of claim 1, wherein said data field and said signature field are transmitted in parallel.
- 3. The method of claim 1, wherein a length of said signature field is set substantially equal to a width of a transmission slot.
- 4. The method of claim 1, wherein a length of said data field is selectively varied.
- 5. The method of claim 1, wherein said signature field comprises at least one of a plurality of signature patterns.
- 6. The method of claim 1, wherein said direct sequence-code division multiple access physical channel comprises an uplink common physical channel.
- 7. A method of transmitting data on a DS-CDMA common physical channel, comprising the steps of:transmitting a data part of a signal; transmitting a signature part of said signal in parallel with said data part, wherein said signature part is spread by a predetermined code, and said data part is spread by a code associated with said signature part; and said signature of said signal can also function as a pilot signal.
- 8. The method of claim 7, wherein said signature part is selected from a predetermined set including at least one signature.
- 9. The method of claim 8, wherein said predetermined set comprises an orthogonal set.
- 10. The method of claim 7, wherein said data part and said signature part are scrambled by a predetermined scrambling code.
- 11. The method of claim 7, further comprising the step of transmitting said signature part and said data part from a mobile station.
- 12. The method of claim 11, wherein said signature part further comprises a pilot signal.
