Abstract  Abstract

In a system which supports code division multiple access communication among members of a first group of terminals and among a second group of terminals a method comprises: assigning to the first group of terminals a first code each user of the first group being unique identifiable by a unique code phase offset; assigning to the second group of terminals the same code as used by the first group but each user of the second group using a common phase offset of that code and assigning to each user of the second group an additional code the additional code being unique for each of the terminals of the second group. A wireless communication system comprises: a first set of access units and a second set of access units the first set of access units and the second set of access units capable of communicating with a central base station wherein the first set of access units use a chip rate scrambling code to separate their user channels each individual unit of the first set of access units having at least one unique non-orthogonal scrambling sequence that is selected from a unique phase shift of a longer pseudorandom noise sequence and wherein the second group of access units share a common chip rate scrambling code that is not used by the first group of access units.
