Abstract
Techniques for efficient allocation of channelization codes are disclosed. In one aspect, a dedicated data channel is partitioned into a primary channel and a secondary channel. The rate of the primary channel is a relatively low fixed rate. The rate of the secondary channel varies over time in accordance with the rate of the dedicated channel data. In another aspect, a channelization code indicator is transmitted in the primary channel to identify the secondary channel. In yet another aspect, more than one secondary channel may be deployed. Various other aspects are also presented. These aspects have the benefit of efficient code resource allocation, resulting in increased support for users/and or channels, as well as increased system capacity.
