Systems and methodologies are described that facilitate increasing throughput in a time-division duplexed CDMA wireless communication environment. A set of orthogonal Walsh code sequences can be assigned to a first group of users in a network sector, and a duplicate set of orthogonal Walsh code sequences can be assigned to at least a second group of users in the sector. A number of receive antennas equal or greater than to the number of duplicate code sets being assigned can be deployed to linearly scale sector capacity to meet user demand. Additionally, user devices employing duplicate Walsh code sequence assignments at a base station serving the sector can be distinguished from each other, and timing offsets between such users can be enforced to mitigate any jamming effect at the base station receiver. Still furthermore, user device channel requirements in the sector can be continuously evaluated and an appropriate number of antennas can be dynamically deployed to provide scalable service to all such user devices.
