ABSTRACT:
A method for establishing communications between a master unit and a plurality of node units. Of the plurality of node units, K node units are assumed to have established communications with a master unit. A first (K+1) node unit of the plurality of node units, desires to establish communications with the master unit. The method includes transmitting from the master unit, a base-station spread spectrum signal having a common signalling chip code, transmitting from the first node unit a second spread spectrum signal with a first identification code using the common-signalling chip code, transmitting from the master unit a third spread spectrum signal with a master unit identification code, using the common-signalling chip code. The method further includes generating at the first node unit using the master unit identification signal, a master unit chip code for transmitting spread spectrum signals to the master unit. Additionally, the method includes generating, at the master unit using the first identification code, a first node unit chip code for transmitting spread spectrum signals to the first node unit.
