    Abstract: According to one embodiment of the present invention, suggested art a method for reporting a power headroom report (hereinafter, PHR) of a terminal and an apparatus of the terminal, the method comprising the steps of: determining whether the terminal is operated in dynamic time division multiple access (hereinafter, TDD, time division duplexer) mode; determining whether the terminal receives service from a plurality of serving cells, when it is determined that the terminal is operated in dynamic TDD mode; determining a power headroom type (hereinafter, PH type) on the basis of a radio resource control (hereinafter, RRC) message and downlink control information (DCI) received from a base station, when it is determined that the terminal receives a service from the plurality of serving cells; and transmitting information about the determined PH type using an extended PHR format. In addition, suggested are a method for receiving a PHR by a base station and a base station apparatus capable of setting a TDD mode in the terminal and receiving the PHR from the terminal.

    Abstract: The present disclosure relates to a communication technique for converging an IoT technology with a 5G communication system for supporting a higher data transmission rate beyond a 4G system, and a system therefor. The present disclosure may be applied to an intelligent service (for example, a smart home, a smart building, a smart city, a smart car or connected car, healthcare, digital education, retail business, a security and safety related service, or the like) on the basis of a 5G communication technology and an IoT related technology. The present invention provides a method for performing random access by a terminal in a wireless communication system supporting beamforming, the method comprising the steps of: receiving, from a base station, uplink resource information for transmitting a preamble and random access response (RAR) information corresponding to the resource information; determining, on the basis of the uplink resource information, a resource for transmitting at least one preamble through beam sweeping; and transmitting the at least one preamble to the base station through the beam sweeping.

    Abstract: The present disclosure relates to a communication method and system for converging a 5G communication system for supporting higher data rates beyond a 4G system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G and IoT-related technologies, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. The present disclosure provides methods and apparatus for scheduling transmission resources between a user equipment and a base station. A method includes detecting a buffer status report (BSR) triggering event based on a BSR retransmission timer, identifying a highest priority logical channel (LCH) having data available for transmission in response to the detected event, identifying SR configuration information corresponding to the highest priority LCH and transmitting, to a base station, an SR based on the identified SR configuration information.

    Abstract: The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. A control method of a user equipment (UE) in a wireless communication system is provided. The method includes receiving packet data conversion protocol (PDCP) configuration information including information indicative of whether a PDCP layer supports out-of-sequence delivery; identifying whether the PDCP layer supports out-of-sequence delivery based on the PDCP configuration information; and processing a PDCP packet data unit (PDU) based on a result of identifying whether the PDCP layer supports out-of-sequence delivery.
