Description

Method and apparatus for SS/PBCH block frequency location indication The present application is a divisional application of the invention patent application with the application date of 2018, 12 and 21, the application number of 201880081964.X and the invention name of 'method and device for SS/PBCH block frequency position indication'. Technical Field The present application relates generally to signaling. More particularly, the present disclosure relates to SS/PBCH block frequency location indication in advanced wireless communication systems. Background In order to meet the increasing demand for wireless data services since the deployment of 4G communication systems, efforts have been made to develop improved 5G or pre-5G communication systems. Therefore, a 5G or pre-5G communication system is also referred to as a "super 4G network" or a "LTE-after-system". A 5G communication system is considered to be implemented in a higher frequency (millimeter wave) band (e.g., 60GHz band) in order to achieve a higher data rate. Beamforming, massive multiple-input multiple-output (MIMO), full-Dimensional MIMO (FD-MIMO), array antennas, analog beamforming, massive antenna techniques are discussed in 5G communication systems in order to reduce propagation loss of radio waves and increase transmission distances. Further, in the 5G communication system, development for system network improvement is being conducted based on advanced small cells, cloud radio access networks (Radio Access Network, RAN), ultra dense networks, device-to-device (D2D) communication, wireless backhaul, mobile networks, cooperative communication, coordinated multipoint (Coordinated Multi-Points, coMP), receiving end interference cancellation, and the like. In 5G systems, hybrid FSK AND QAM Modulation (FQAM) and sliding window superposition coding (sliding window superposition coding, SWSC) have been developed as advanced code Modulation (advanced coding Modulation, ACM), as well as filter bank multicarrier (filter bank multi carrier, FBMC), non-orthogonal multiple access (non-orthogonal multiple access, NOMA) and sparse code multiple access (sparse code multiple access, SCMA) as advanced access technologies. The internet is a person-centric connected network in which humans generate and consume information, which is now evolving towards the internet of things (Internet of Things, ioT) in which distributed entities (such as things) exchange and process information without human intervention. A web of everything (Internet of Everything, ioE) has emerged, which is a combination of IoT technology and big data processing technology through a connection with a cloud server. Because IoT implementations require technical elements such as "sensing technology," "wired/wireless Communication and network infrastructure," "service interface technology," and "security technology," research has recently been conducted on sensor networks, machine-to-Machine (M2M) communications, machine-type communications (MACHINE TYPE communications, MTC), and the like. Such IoT environments may provide intelligent internet technology services that create new value for human life by collecting and analyzing data generated among networking things. Through convergence and combination between existing information technology (Information Technology, IT) and various industrial applications, ioT can be applied in a variety of fields including smart homes, smart buildings, smart cities, smart or networked automobiles, smart grids, healthcare, smart appliances, and advanced medical services. Consistent with this, various attempts have been made to apply 5G communication systems to IoT networks. For example, techniques such as sensor networks, machine Type Communications (MTC), and machine-to-machine (M2M) communications may be implemented by beamforming, MIMO, and array antennas. The application of cloud Radio Access Networks (RANs) as the big data processing technology described above may also be regarded as an example of a fusion between 5G technology and IoT technology. For a New Radio (NR) licensed spectrum, each synchronization and physical broadcast channel (physical broadcasting channel, PBCH) signal block (SS (synchronization signal, synchronization signal)/PBCH block) includes one symbol for an NR primary synchronization signal (NR-primary synchronization signal, NR-PSS), two symbols for an NR-PBCH, and one symbol for an NR secondary synchronization signal (NR-secondary synchronization signal, NR-SSs) and NR-PBCH, where the four symbols are mapped and time division multiplexed sequentially. NR-SS is a unified design for all supported carrier frequency ranges in NR, including NR-PSS and NR-SSS sequence designs. The transmission bandwidths of NR-PSS and NR-SSS are smaller than the transmission bandwidth of the entire SS/PBCH block. For initial cell selection of NR cells, the UE assumes a default SS burst set (SS burst set) period of 20ms and is used to detect non-independent N
