    摘要: Provided is a terminal for performing transmission and reception of data in a wireless communication system, wherein the terminal receives, from a base station, first configuration information for code block group (CBG)-based uplink transmission, and second configuration information including a downlink feedback information (DFI) bitmap configuration method, transmits a CBG-based uplink signal to the base station, based on the first configuration information, receives, from the base station, DFI including feedback information about the CBG-based uplink signal, based on the second configuration information, and determines a contention window value of the terminal, based on the feedback information included in the received DFI, wherein the DFI bitmap configuration method indicates whether the feedback information is for feedback in units of transport blocks (TBs) or for feedback for one or more CBGs.

    摘要: A communication method and system for converging a fifth generation (5G) communication system for supporting higher data rates beyond a fourth generation (4G) system with a technology for internet of things (IoT) are provided. The communication method and system 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 method of a terminal for receiving data in a cellular network is provided. The method comprises receiving a synchronization signal block (SS block) including at least one synchronization signal and a physical broadcast channel (PBCH) from a base station, identifying a subcarrier offset between the SSB and a resource block (RB) grid based on system information on the PBCH, and identifying a location of the SSB based on the offset.

    摘要: 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). A method of a terminal in a communication system comprises receiving, from a base station, a power headroom reporting, PHR, configuration including information indicating whether power headrooms for a multiple transmission and reception points, TRPs, to be reported; identifying the power headrooms for the multiple TRPs in case that the information indicates the power headrooms for the multiple TRPs to be reported; and transmitting, to the base station, a PHR including the power headrooms for the multiple TRPs in case that the PHR is trigged.
