Abstract
A high data rate active set of base stations services high data rate forward link transmissions for a mobile station. Membership of the high data rate active set of base stations is determined via interaction with legacy standard operations that define a legacy standard active set of base stations for the mobile station. The high data rate forward link active set of base stations may be a subset of the legacy standard active set of base stations. The high data rate forward link active set of base stations may correspond directly to a reduced active set of base stations according to the legacy standard operations, e.g., reduced active set. According to another operation, access to newly added base stations to the high data rate forward link active set of base stations is precluded until the newly added base station is available to support forward link transmissions.
