ABSTRACT:
A system and method for W-CDMA transmissions from the base to a remote unit and spread-TDMA transmissions from the remote unit to the base. By using spread-TDMA on the reverse link, limitations inherent with the use of CDMA due to non-zero cross correlation are avoided. The resulting system provides high quality performance in both directions.
