Method for Mapping a Logical Channel in a Media Access Control (MAC) Stream and System for Mapping a Logical Channel in a Media Access Control (MAC) The present invention discloses a method for mapping a logical channel in a media access control (MAC) stream. medium access control (mac), the method includes a radio network controller (rnc) informs a user equipment (eu) about the corresponding relationship between a common control channel (ccch) and expanded dedicated channel mac flow (e-dch) by signaling; eu receives the signaling, and obtains the corresponding relation between the mac flow of ccch and e-dch. The present invention further discloses a system for mapping a logical channel in a mac stream. Through the method and system disclosed in the present invention, it is convenient for a node b (nob) to be able to obtain precisely the corresponding ratio between the mac flow of ccch and e-dch, which ensures that the node decodes correctly, thus improving the success rate of receiving signaling and data.
