    摘要: 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.

    摘要: 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.

    摘要: 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.

    摘要: A centralized scheduling method and apparatus is provided for minimizing inter-cell interference in the wireless communication system adopting femto-eNB-based service coverage expansion (range expansion). The method includes establishing, by a server, a connection with at least one base station, collecting channel information between the at least one base station connected to the server and terminals, determining interfering base stations causing interference to each terminal based on the channel information, and selecting the terminals to be scheduled in consideration of the interfering base stations.
