    Abstract: Disclosed is a 5G (5th generation) or pre-5G communication system for supporting a data transmission rate higher than that of a 4G (4th generation) communication system such as a long term evolution (LTE). The present disclosure is for allocating and indicating resources in a wireless communication system, and an operation method of a base station comprises the steps of: allocating a first resource for a first service; allocating a second resource for a second service in consideration of the first resource; and transmitting resource allocation information on the second resource and data of the second service, wherein the second resource is discontinuously allocated, at a frequency axis, in a logical or physical manner, and the resource allocation information indicates the second resource by using at least one starting location and at least one length.

    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 wireless device for receiving signals, a base station for transmitting a master information block (MIB) in a wireless communication network and a method therefore are provided. The wireless device comprises a receiver configured to receive, from a base station, a master information block (MIB) for a first communication using a first frequency bandwidth, and a processor configured to identify a frequency offset between a center frequency of the first frequency bandwidth and a channel raster for a second communication using a second frequency bandwidth based on information in the MIB. The receiver is further configured to receive, from the base station, signals, through the first communication, based on the frequency offset. The first frequency bandwidth is narrower than the second frequency bandwidth.

    Abstract: A 5th generation (5G) or pre-5G communication system supporting higher data rate after a 4th generation (4G) communication system such as a long-term evolution (LTE) is disclosed. The system includes a scalable frame structure to integrally support various services in a cellular wireless communication system, and provides a transmission/reception method to which the corresponding frame structure is applied, so that the system performance is improved through minimizing of inter-symbol interference between the 5G system and the LTE system or between the 5G systems. The scalable frame structure adjusts a cyclic prefix (CP) length by giving a specific pattern thereto when subcarrier spacing is extended, while maintaining a CP overhead in the same manner based on the frame structure based on a specific subcarrier spacing, thereby maintaining the 2m-times relationship between a symbol length, CP length, slot length, and subframe length.

    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 for operating a BS for supporting mixed numerology in a wireless communication system. The method includes: generating a first signal for a first group and a second signal for a second group according to different configurations; and transmitting the first signal through a first channel allocated for the first group and the second signal through a second channel allocated for the second group.

    Abstract: A filtering-based signal transmission method is provided. The method includes a transmitter performing carrier modulation on each signal from at least one sub-band, and adding a cyclic prefix and a cyclic postfix thereto, respectively, performing time-domain filtering on the signal, added with the cyclic prefix and the cyclic postfix, from the respective sub-band, and transmitting the filtered signal from the at least one sub-band. The present disclosure further provides a filtering-based signal receiving method. The filtering-based signal receiving method includes performing, by a receiver, time-domain matched filtering, corresponding to at least one sub-band, on each received signal, removing, by the receiver, a cyclic prefix and a cyclic postfix from the filtered signal from the at least one sub-band, and performing carrier demodulation, respectively, and detecting and estimating, by the receiver, the demodulated signal from the at least one sub-band.
