Abstract:
1. A method of transmitting control information by a transmitting side device in a wireless communication system, the method comprising: generating, at a medium access control (MAC) layer that resides below a radio link control (RLC) layer, a MAC protocol data unit (PDU), comprising combining at least one MAC header with at least one service data unit (SDU) received from an upper layer; adding an indicator in the MAC PDU in response to identifying control information to be included in the MAC PDU, the control information comprising buffer status information of the transmitting side device and the indicator for indicating a presence of the control information in the MAC PDU, wherein the indicator is added to the MAC PDU only when the control information is added to the MAC PDU during the generating step; and transmitting the MAC PDU via an uplink dedicated channel, wherein the transmitted MAC PDU either includes the indicator and control information or does not include the indicator and control information according to the adding step.
