Abstract:
1. A method of configuring at least one radio resource in a wireless communication system, the method comprising: receiving, by a radio resource control (RRC) layer of a terminal, a RRC message related to a radio resource configuration from a base station, wherein the message is used to configure the at least one radio resource; receiving, by a medium access control (MAC) layer of the terminal, a medium access control (MAC) protocol data unit (PDU) from a MAC layer of the base station, wherein the RRC layer's reception of the message is separate from the MAC layer's reception of the MAC PDU including activation time information; checking, by the medium access control (MAC) layer of the terminal, whether a MAC sub-header of the MAC PDU includes a special logical channel identifier (LCID) value, wherein the special LCID value indicates an existence of an MAC control element including the activation time information; after the special LCID value indicating the existence of the MAC control element including the activation time information is detected, acquiring by the MAC layer of the terminal, the activation time information from the MAC control element of the MAC PDU; and after the activation time information is acquired, configuring, by the MAC layer of the terminal, the at least one radio resource at a time, which is indicated by the activation time information, wherein during the time indicated by the activation time information, the configuring of the at least one radio resource is performed by the MAC layer of the terminal, such that parameters relating to the at least one radio resource are applied to both the MAC layer of the terminal and the MAC layer of the base station; and if the special LCID value indicating the existence of the MAC control element including the activation time information is not detected and if a MAC response request message from the base station is received, transmitting a MAC response message to the base station such that parameters relating to the at least one radio resource are applied to both the MAC layer of the terminal and the MAC layer of the base station immediately after transmitting the MAC response message.
