Patent CA-2454055-A1 (CA)
Inventor: ALAPURANEN PERTTI O
IPC: H04W72/04
Filed: 2002-07-16
Abstract: A technique for allowing a first and second group of users to share access to a communication channel such as a wireless radio channel is disclosed. The first group of users (110) can be a group of legacy users such as those that use digital CDMA cellular telephone equipment based on the IS-95 standard. The second group of users (210) can be a group of web surfers that code their transmissions using one of multiple formats. The first group of users (110) can share one modulation structure such as, on a reverse link, using unique phase offsets of a common pseudorandom noise (PN) code. The second group of users (210) can share another modulation structure, but in a manner that is consistent and compatible with the users of the first group (110).  Specifically, the users of the second group (210) may all use the same PN code and code phase offset. Each channel used by the second group of users (210) can be uniquely identified by a corresponding unique orthogonal code.
