    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. Provided are a method and apparatus for uplink scheduling in a mobile communication system. The method of uplink scheduling for a user equipment (UE) in a mobile communication system may include identifying the amount of data stored in a buffer, generating a scheduling request (SR), and transmitting the SR to a base station (NB) on the basis of the identified data amount so that an uplink resource is to be allocated from the NB.

    Abstract: The disclosure relates to a communication technique for convergence of an IoT technology and a 5G communication system for supporting a higher data transmission rate beyond a 4G system, and a system therefor. The disclosure can be applied to an intelligent service (for example, a smart home, a smart building, a smart city, a smart cart or connected car, health care, digital education, retail business, security and safety-related service, etc.) on the basis of a 5G communication technology and an IoT-related technology. The disclosure defines a mobility method for a terminal residing in a system in which transmission/reception points (TPRs), supporting solely some protocols among entire access stratum protocols comprising PHY, MAC, RLC, PDCP, and RRC, coexist in a wireless communication system. Specifically, the disclosure defines a method for dynamically changing, depending on determination by a base station, a beam and a transmission/reception point to be used for transmitting information to or receiving information from a terminal through a method in which a system using multiple beams notifies, in advance, of a measurement reference signal transmitted using transmission/reception points of different networks, to allow a terminal to select a required reception beam from a corresponding resource and measure beam information of each transmission/reception point, or a terminal transmits measured information as feedback in which each transmission/reception point is specified. Accordingly, the disclosure can provide a criterion of rapid and highly precise determination for changing a beam and a transmission/reception point and thus prevent a terminal from needlessly measuring and reporting, so as to achieve an effect of reduction in the power consumption of the terminal and reduction of delay in change of a transmission/reception point.

    Abstract: The present disclosure relates to a communication scheme for the convergence of a 5G communication system for supporting a higher data transfer rate after the 4G system and the IoT technology and a system thereof. A method for performing a scheduling request (SR) is provided. The method performed by a user equipment (UE) comprises receiving, from a base station, first information on a mapping relation between an SR configuration and a logical channel (LCH), receiving, from the base station, second information on a condition for initiating a regular buffer status report (BSR) transmission procedure regardless of priority, and transmitting, to the base station, the SR based on the first information and the second information.

    Abstract: A communication method and a system that combines fifth generation (5G) communication systems with internet of things (IoT) technologies to support much higher data rates than fourth generation (4G) communication systems are provided. Based on 5G communication technologies and IoT technologies, the present disclosure can be applied to intelligent services, such as smart home, smart building, smart city, smart car or connected cars, health care, digital education, retail business, and security and safety measure. A method of communication for a user equipment includes receiving a random access channel (RACH) configuration from a base station (an evolved nodeB (eNB)), and transmitting to the eNB a random access preamble (RAP) message in an uplink subframe of an unlicensed band matching a subframe configured as a RACH resource according to the RACH configuration.

    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). Disclosed is a method of reporting beam measurement state information by a User Equipment (UE). The method may include: measuring beam state information by using a first reception chain and a second reception chain; controlling beam state information on the first reception chain to correspond to beam state information on the second reception chain; calculating state information on each beam based on the controlled beam state information on the first reception chain and beam state information on the second reception chain; and reporting state information on one or more beams.
