| 1. A method of transmitting data of a plurality of different first data types on a physical channel supporting a second data
type in a wireless packet data communication system, comprising the steps of:
generating a data unit of a first data type;
determining whether the data unit of the first data type is to be transmitted in the second data type; and
generating a data unit of the second data type by attaching multiplexed (MUX) header information supporting the second data
type to the data unit of the first data type, if the data unit of the first data type is to be transmitted in the second data
type, and comprising:
forming a first header, which is specific to the second data type, in the data unit of the second data type that comprises
an extension indicator for indicating whether a second header is present;
forming the second header comprising information about the data unit of the first data type, after the first header; and
forming a payload comprising the data unit of the first data type, after the second header.
