A base station including a plurality of antenna assemblies in a mobile communication system divides an ultra wideband into a plurality of unit-bands (UBs), forms a plurality of beams by the plurality of antenna assemblies, groups a plurality of beam component carriers distinguished by the plurality of UBs into beam component carriers that belong to the same UB to operate the grouped beam component carriers as a plurality of cells, and configures one cell among the plurality of cells as a cell for movement of a terminal.

Method and apparatus for operating system in cellular mobile communication system

A base station of a mobile communication system divides an ultra wideband into a plurality of unit bands, uses a plurality of beam component carriers corresponding to the L3 CP dedicated unit band as a coverage layer by grouping in one cell in the L3 CP dedicated unit band and uses a plurality of beam component carriers corresponding to the UP dedicated unit band in the UP dedicated unit band as a plurality of capacitor layers by grouping in a plurality of cells of a smaller size than that of the grouping.

Radio resource management apparatus of base station in mobile communication system and method of managing the same

Provided is a method of managing mobility of a user equipment. The method includes: establishing by a first base station a communication with the user equipment; transmitting by the first base station a Coordinated Multiple Point (CoMP) addition request to a second base station; establishing by the first and second base stations a CoMP communication with the user equipment according to the CoMP addition request; transmitting by the first base station an anchor cell change request to the second base station; and operating the second base station as an anchor cell of the CoMP communication according to the anchor cell switch request.

Method of managing mobility using coordinated multiple point communication

Disclosed is an operating method of a base station which includes searching user equipment, having a machine to machine (hereinafter, referred to as M2M) communication function, from user equipment under communication; sending an M2M call setup request to the searched user equipment; sending a handover call setup request to the remaining user equipment from among the user equipment under communication; and entering a power-saving mode.

Effective energy saving method of next generation mobile communication

When transmitting a user message, in a call setting period of a base station and a terminal and a radio connection state between a base station and a terminal, whenever a data transmittable channel resource is available, user messages of an amount corresponding to the available channel resource are transmitted. Therefore, user messages can be divided and transmitted according to an available channel in a call setting period.

Method of transmitting user message, terminal and base station using the method
