CODE CHANNEL MANAGEMENT IN A WIRELESS COMMUNICATIONS SYSTEM

摘要

Systems and techniques are disclosed relating to communications. The systems and techniques involve dividing a plurality of subscriber stations into a plurality of groups, assigning a different plurality of orthogonal codes to each of the groups, the number of the orthogonal codes assigned to one of th e groups being less than the number of subscriber stations in said one of the groups, encoding communications to one of the subscriber stations in said on e of the groups at a data rate, and determining whether to spread at least a portion of communications to said to one of the subscriber stations with one of the orthogonal codes assigned to said one of the groups as a function of the data rate.
