Abstract:
Systems and methods for Walsh code assignment are provided. In accordance with the disclosed exemplary embodiments, when a set of mobile communication units (MU) is in a control/hold state, instead of a base transceiver station (BTS) assigning Walsh codes for respective dedicated control channels (dcch ) to the set of mobile communication units (MU) on a one-to-one basis, the base transceiver station (BTS) circulates the Walsh codes among the set of mobile communication units (MU). Thus, at a given time, the base transceiver station (BTS) has assigned the available Walsh codes to only a subset of the mobile communication units (MU) in the control/hold state. Accordingly, this Walsh code assignment allows the system to support more mobile communication units (MU) in the control/hold state.
