USTS - Uplink Synchronous Transmission Scheme

To maximize the usage of 3G uplink capacity the 3GPP (Third Generation Partnership Project) is exploring techniques in which channel redundancy can be exploited. One approach is to implement USTS in which signals from mobiles within the cell are orthogonalized. That is, a number of mobiles are allocated the same scrambling code, but different channelization codes.
