Abstract:
1. A wireless communication system, comprising: a network; and a plurality of base transceiver stations (BTS) coupled to said network, wherein at least one of said base transceiver station (BTS) is adapted to reassign Walsh codes on a time basis among a plurality of mobile communication units (MU) in a control/hold media access control (MAC) state by assigning a set of Walsh codes to a first subset of the plurality of mobile communication units (MU) during a first period of time and assigning the set of Walsh codes to a second subset of the plurality of mobile communication units (MU) during a second period of time, and by notifying mobile communication units (MU) that are in the first subset but not the second subset that an assigned Walsh code is inactive during the second period of time and notifying mobile communication units (MU) that are in the second subset but not in the first subset that a particular Walsh code of the set of Walsh codes is assigned, wherein the mobile communication units (MU) comprising the first and second subsets is not identical.
