    Abstract: The disclosure relates to a communication scheme and a system therefor which combines IoT technology and a 5G communication system for supporting a higher data transmission rate than a 4G system. The disclosure may be applied to a smart service (e.g., a smart home, a smart building, a smart city, a smart car or connected car, healthcare, digital education, retail business, a security and security related service, or the like) based on the 5G communication technology and the IoT related technology. According to an embodiment of the disclosure, there is provided a method of a sidelink reception user equipment (UE) in a communication system. The method includes: receiving, from a base station, configuration information associated with power control for transmission of a physical sidelink feedback channel (PSFCH); receiving a plurality of physical sidelink shared channels (PSSCH) scheduled based on a plurality of sidelink control information (SCI); identifying at least one first PSFCH based on the number of PSFCHs scheduled in response to reception of the plurality of PSSCHs and the maximum number of PSFCHs that the first UE is capable of transmitting; in case that total transmission power for the at least one first PSFCH is greater than maximum transmission power of the first UE, identifying at least one second PSFCH in order of high priority indicated by the plurality of SCI, wherein a number of the at least one second PSFCH is the maximum number of PSFCHs which enables the sum of transmission power to be less than or equal to the maximum transmission power; identifying first transmission power for each of the at least one second PSFCH based on the number of the at least one second PSFCH; and transmitting the at least one second PSFCH based on the first transmission power.

    Abstract: The present disclosure relates to a communication technique for combining an IoT technology with a 5G communication system for supporting a higher data transmission rate than a 4G system, and a system therefor. The present disclosure can be applied to intelligent services (for example, smart homes, smart buildings, smart cities, smart cars or connected cars, health care, digital education, retail businesses, security and safety-related services, and the like) on the basis of 5G communication technologies and IoT-related technologies. A method for a terminal in a wireless communication system, according to the present disclosure, comprises: measuring reference signal received power (RSRP) values corresponding to respective synchronization signal blocks (SSBs) on the basis of a plurality of SSBs which have been transmitted by a base station; identifying a coverage enhancement (GE) level of the terminal on the basis of measured RSRP values and at least one RSRP threshold; and transmitting at least one random access preamble to the base station on the basis of the identified CE level.

    Abstract: The present disclosure relates to a 5th generation (5G) or pre-5G communication system for supporting a higher data transfer rate than a 4th generation (4G) communication system such as long term evolution (LTE). According to various embodiments of the present disclosure, a method performed by a terminal in a wireless communication system may comprise the steps of: determining whether a reference signal received power (RSRP) of a reference for downlink path loss is equal to or greater than a threshold value; if the RSRP is greater than the threshold value, setting a random access type to 2-step random access; and if the RSRSP is not greater than the threshold value, setting the random access type to 4-step random access.

    Abstract: The disclosure relates to 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), and may be applied to intelligent services based on the 5G communication technology and IoT-related technology. According to an embodiment of the disclosure, a method performed by a terminal is provided. The method includes receiving, from a base station, configuration information for skipping an uplink transmission; identifying a grant for a PUSCH transmission; identifying whether one or more conditions for skipping a generation of a MAC PDU for the PUSCH transmission are satisfied, wherein the one or more conditions include a condition that no UCI is to be multiplexed on the PUSCH transmission; and skipping the generation of the MAC PDU based on the configuration information, the grant, and an identification that the one or more conditions are satisfied.
