Abstract
The present invention encompasses a base station and method of providing communication services to a plurality of communication units. The method includes the steps of sending communication information between the base station and at least two of the plurality of communication units. A first step of identifying communication units produces a group identifier. A scrambling code, based at least in part on the group identifier, is then used to encode the communication information for transmission.
