Zusammenfassung:A method and apparatus are provided for transmitting data to access terminals by an access node in a Code Division Multiple Access (CDMA) system operating at least 128 Medium Access Control Identifiers (MAC IDs) in one sector. A preamble set for transmitting a multi-user packet (MUP) is configured to a specific access terminal, information on the preamble set is provided to the terminal, and data is transmitted to an access terminal having a MAC ID of 128 or higher using a preamble corresponding to the MAC ID. If a specific access terminal has a MAC ID of 128 or higher, the preamble set includes at least one preamble with which the access terminal determines whether the MUP is received. The access node provides information on the preamble set to the access terminal during session configuration.
