In the method a code mask for coding transmission over a traffic channel is generated based on a base station differentiator and a traffic channel differentiator. Base station differentiators are used to differentiate between different base stations and traffic channel differentiators are used by a base station to differentiate between different traffic channels assigned by a base station.

I claim: 1. A method for coding reverse-link transmissions in a wireless communication system to differentiate among the transmissions, comprising: generating, by a network element, a code mask for coding the reverse-link transmissions, the code mask including a first number of bits forming a fixed portion thereof and a second number of bits forming a variable portion thereof; wherein the variable portion of the code mask comprises a base station differentiator, a traffic channel differentiator, and a number of filler bits as required to cause the number of bits in the variable portion to satisfy a given transmission standard. 2. The method of claim 1, wherein the base station differentiator includes a PN offset for a base station assigning the reverse-link transmission channel and a base station identifier for the assigning base station. 3. The method of claim 1, wherein the generating step generates the code mask by concatenating the base station differentiator and the traffic channel differentiator and the number of filler bits in any predetermined order. 4. The method of claim 3, wherein the number of filler bits further includes a fixed bit string. 5. The method of claim 1, wherein the generating step multiplexes bits of the base station differentiator and the traffic channel differentiator together and includes the multiplexed bits in the code mask. 6. The method of claim 1, wherein the generating step encodes and permutates bits of one of the base station differentiator and the traffic channel differentiator, and includes the encoded or permutated bits in the code mask. 7. The method of claim 1, further comprising: sending, from the base station assigning the traffic channel, a message indicating the code mask. 8. The method of claim 1, wherein the generating step generates the code mask as a default method of generating the code mask. 9. The method of claim 1, further comprising: sending the code mask to a mobile station. 10. The method of claim 9, wherein the sending step sends the code mask during one of call activation and hand-off. 11. The method of claim 1, further comprising: receiving, at a base station, over the traffic channel using the code mask. 12. A method for coding transmission to differentiate transmission over traffic channels from a mobile station, comprising: receiving, by a network element, a PN offset, a Walsh code, and a number of filler bits, the number of filler bits including a base station identifier for the base station assigning the traffic channel; generating a code mask for coding transmissions over a traffic channel based on the received PN offset, the received Walsh code, and the base station identifier; and coding the code mask onto the transmission over the traffic channel. 13. A method for coding transmission to differentiate transmission over traffic channels at a mobile station, comprising: receiving, by a network element, a code mask during one of call activation and hand-off, the code mask for coding transmissions over a traffic channel and including a base station differentiator, a Walsh code of the traffic channel, and a number of filler bits, the number of filler bits including-a base station identifier for the base station assigning the traffic channel; and coding the code mask onto the transmissions over the traffic channel. 14. A method for coding transmission to differentiate transmission over traffic channels from a mobile station, comprising: generating, by a network element, a code mask for coding transmissions over a traffic channel based on a base station differentiator, a traffic channel differentiator, and a number of filler bits, the number of filler bits including a base station identifier for the base station assigning the traffic channel; coding the code mask onto the transmissions over the traffic channel; and transmitting over the traffic channel using the generated code mask.
