    Abstract: The present disclosure relates to a communication technique for converging a 5G communication system for supporting a higher data transfer rate beyond a 4G system with IoT technology, and a system therefor. The present disclosure may be applied to intelligent services (for example, smart homes, smart buildings, smart cities, smart cars or connected cars, health care, digital education, retail business, security and safety-related services, etc.) on the basis of 5G communication technology and IoT-related technology. The present disclosure relates to a method for assigning transmission resources including an uplink (UL)-dedicated region and a downlink (DL)-dedicated region, the method comprising: a step for identifying a ratio of the DL-dedicated region to the UL-dedicated region; a step for changing the ratio of the DL-dedicated region to the UL-dedicated region by using at least one of a utilization rate and electric field characteristic information of the transmission resources; and a step for assigning the UL-dedicated region and the DL-dedicated region according to the changed ratio of the DL-dedicated region to the UL-dedicated region.

    Abstract: The disclosure relates to a 5G or pre-5G communication system for supporting higher data transmission rates than 4G communication systems such as LTE systems. According to the disclosure, a method for performing beamforming by a base station in a wireless communication system comprises obtaining transmission time proportions allocated to a plurality of beam directions and performing beamforming to send control information in the plurality of beam directions based on the obtained transmission time proportions. A base station configured to perform beamforming in a wireless communication system, includes a transceiver configured to perform beamforming communication with a UE, and a processor configured to obtain transmission time proportions allocated to each of a plurality of beam directions, and control beamforming for sending control information based on the obtained transmission time proportions.

    Abstract: A communication system is provided. The communication system supports higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). A first apparatus in a wireless communication system is provided. The apparatus includes an antenna array, at least one transceiver, and at least one processor. The transceiver is configured to transmit signals by using a beam set, and receive a signal for indicating at least one beam in the beam set from a second apparatus. The processor is configured to determine an auxiliary beam pair, based on the at least one beam. The transceiver is configured to transmit reference signals to the second apparatus by using the auxiliary beam pair, and receive feedback information relating to the auxiliary beam pair from the second apparatus. The at least one processor is configured to determine, based on the feedback information, a communication direction relating to the second apparatus.

    Abstract: The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates beyond 4th-Generation (4G) communication system such as long term evolution (LTE). A terminal in a wireless communication system is provided. The terminal includes a transceiver, and at least one processor configured to receive, from a base station (BS), a beam failure recovery configuration comprising at least one reference signal for identifying a candidate beam for the beam failure recovery and associated random access (RA) parameters, identify the candidate beam for the beam failure recovery using the at least one reference signal, and perform a physical random access channel (PRACH) using the at least one reference signal and the associated RA parameters on the candidate beam for the beam failure recovery.

    Abstract: Provided are a method and apparatus for scheduling user equipments. The apparatus for allocating resources to UEs may include: a communication unit to send and receive data to and from one or more UEs; and a control unit to perform a process of determining the first maximum throughput based on channel quality information received from one or more UEs and UE levels, performing a first-stage sorting operation on a list of UEs based on the first maximum throughput and average throughput, performing, when there are two or more UEs that have the same UE level and are adjacent in the list, a second-stage sorting operation on those UEs based on the channel quality information, and allocating resources to at least one UE in the list. Accordingly, when UEs having different UE levels compete for resources, it is possible to increase the overall throughput of the base station.
