SYSTEM AND METHOD FOR CIRCULATING THE ASSIGNMENT OF WALSH CODES AMONG MOBILE UNITS IN CONTROL/HOLD STATES

摘要

Systems and methods for Walsh code assignment are provided. In accordance with the disclosed exemplar embodiments, when a set of mobile communication units (MU) (Fig.2A, 210) is in a control/hold state, instead o a base transceiver station (BTS) (FIG.2A, 206) 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.
