Method for transmitting scheduling information based on the type of logical channel

PURPOSE: A method for transmitting scheduling information according to a logical channel type is provided to prevent a terminal from transmitting unnecessary scheduling information. CONSTITUTION: When transmission data is not in a buffer of a terminal, scheduling information for releasing E-DCH(Enhanced Dedicated Channel) wireless resources is triggered. When a resource area is enough, the terminal transmits an MAC(Medium Access Control) i PDU(Protocol Data Unit) including the scheduling information to a base station. When a logical channel is a DCCH or a DTCH, the terminal transmits the MAC PDU including the scheduling information to the base station after triggering the scheduling information.
