METHOD AND APPARATUS FOR UPLINK CONTROL INFORMATION TRANSMISSION IN WIRELEE CELLULAR COMMUNICATION SYSTEMS

摘要

The present invention relates to a method in which a terminal transmits uplink control information in a mobile communication system. The terminal communication method according to an embodiment of the present invention comprises the steps of: generating uplink control information for at least one active cell; if the active cell belongs to a master cell group (MCG) which is managed by a master base station (MeNB: Mater eNB), configuring uplink control channel by using control information of an active cell belonging to the MCG; and transmitting the configured uplink control channel to a primary cell (Pcell). According to one embodiment of the invention, by providing a process and method in which a terminal can transmit uplink control information to respective base stations, in a system which performs a carrier aggregation between different base stations, it enables a base station to perform an efficient scheduling operation and a terminal to transmit uplink control information efficiently.
