Data transmission within a spread-spectrum communication system

A method for data transmission from a base station within a spread spectrum communication system, the method comprising the steps of:

• determining first data bits to transmit to a first remote unit from the base station, wherein the first data bits include a first remote unit identification and a first Walsh (OVSF) code for use by the remote unit;
• determining second data bits to transmit to a second remote unit from the base station, wherein the second data bits include a second remote unit identification and a second Walsh (OVSF) code for use by the second remote unit, wherein the second Walsh (OVSF) code differs from the first Walsh (OVSF) code;
• scrambling the first data bits with a third Walsh (OVSF) code to produce first scrambled data bits;
• scrambling the second data bits with the third Walsh (OVSF) code to produce second scrambled data bits;
• transmitting the first scrambled data bits to the first remote unit, wherein the first remote unit utilizes the first Walsh (OVSF) code to receive high-speed data transmitted to the first remote unit from the base station;
• and
• transmitting the second scrambled data bits to the second remote unit, wherein the second remote unit utilizes the second Walsh (OVSF) code to receive high-speed data transmitted to the second remote unit from the base station.

• means for scrambling the data bits with a second Walsh (OVSF) code to produce scrambled data bits;
• and
• means for transmitting the scrambled data bits to the remote unit, wherein the remote unit utilizes the first Walsh (OVSF) code to receive second data transmitted to the remote unit from a base station.
