摘要： A method by a terminal of receiving a signal is disclosed, using a narrowband internet of things, NB-IoT, in a wireless communication system. The method comprises receiving, from a base station, a master information block, MIB, for the NB-IoT, the MIB including at least one of first information on a sequence for a reference signal of the NB-IoT and second information on a number of antenna ports for the reference signal. The method comprises receiving, from the base station, the reference signal of the NB-IoT based on at least one of the first information and the second information.

摘要： The disclosure concerns a method performed by a terminal and comprises: receiving, from a base station, a primary synchronization signal, PSS, and a secondary synchronization signal, SSS, based on a first subcarrier spacing; receiving, from the base station, a master information block, MIB, based on the first subcarrier spacing, wherein the MIB includes first information associated with a second subcarrier spacing for a physical downlink control channel, PDCCH, and second information associated with a resource for the PDCCH; identifying, based on the first information included in the MIB, the second subcarrier spacing for the PDCCH from one of a first subcarrier spacing set or a second subcarrier spacing set, wherein the first subcarrier spacing set corresponds to a lower frequency band and the second subcarrier spacing set corresponds to a higher frequency band; and receiving, from the base station, the PDCCH based on the second subcarrier spacing and the second information.

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： A soft demapping apparatus and method thereof includes a pre-processing unit to pre-process a reception signal obtained from a symbol representing bits. A candidate selection unit selects two candidates from among constellation points included in a constellation for each of the bits. A distance calculation unit calculates a Euclidean distance between the reception signal and the two candidates. A log-likelihood ratio (LLR) calculation unit calculates an LLR with respect to the bits based on the Euclidean distance between the reception signal and the two candidates.
