    Abstract: An apparatus and method reduce power consumption in a broadband wireless communication system. A transmitting end apparatus that includes a plurality of transmit (Tx) antennas includes a control block, a Processor (DSP) block, a modem block, and at least one power controller. The control block determines a traffic amount based on an amount of used resources. The Digital Signal Processor (DSP) block performs scheduling by using a subset of Tx antennas and a subset of resources on a frequency axis if the traffic amount is less than a threshold. The modem block applies boosting to a signal transmitted using the subset of resources. And at least one controller turns off an operation of at least one power amplifier that corresponds to at least one Tx antenna that is not included in the subset of Tx antennas.

    Abstract: The present disclosure relates to a communication technique for converging a 5G communication system, which is provided to support a higher data transmission rate beyond a 4G system with an IoT technology, and a system therefor. The present disclosure may be applied to an intelligent service (for example, smart home, smart building, smart city, smart car or connected car, healthcare, digital education, retail business, security and safety-related service, etc.) on the basis of a 5G communication technology and an IoT-related technology. The present disclosure relates to an efficient method and device for uplink communication in a narrow band system which provides an IoT service in a band for a broadband system, and a method for uplink communication in a narrow band system according to an embodiment of the present disclosure comprises the steps of: receiving, by a terminal, control information associated with uplink transmission of symbols from a base station; and performing, by the terminal, the uplink transmission using symbols except a second symbol overlapping with a first symbol for transmission of an uplink reference signal in a broadband system, on the basis of the control information.

    Abstract: A method of determining a serving sub-cell of a terminal among a plurality of sub-cells by a base station in a wireless communication system is provided. The method includes generating reference signal transmission interval information for each of the sub-cells by configuring a reference signal transmission interval for each of the plurality of sub-cells, and transmitting the reference signal transmission interval information for each of the sub-cells to the corresponding sub-cell, receiving channel status information for at least one sub-cell among the plurality of sub-cells from the terminal, and determining a serving sub-cell of the terminal by using at least one of the reference signal transmission interval information, the channel status information, a reception time of the channel status information, of each of the sub-cells.
