ABSTRACT:
Increased data communication capacity in a sector of a CDMA wireless system using a combination of code division multiplexing and time division multiplexing. Adjacent subsectors may transmit carrier signals having the same frequency and using the same Walsh codes may be used by imposing a partial offset of the sector PN sequence.
