Abstract: A method and an apparatus for communications using synchronization signal blocks. An operation method of a base station in a mobile communication system includes generating a first synchronization signal/physical broadcast channel (SS/PBCH) block including information indicating whether the first SS/PBCH block is used for initial access of the terminal; and transmitting the generated SS/PBCH block in a first bandwidth part (BP).

Abstract: An operation method of a communication node transmitting a synchronization signal in a communication network may comprise generating a synchronization signal block including the synchronization signal; configuring an offset for the synchronization signal block; generating a synchronization signal burst including a plurality of the synchronization signal blocks based on the offset; and transmitting the synchronization signal based on a synchronization signal burst set including the plurality of the synchronization signal blocks. Accordingly, a terminal can dynamically and effectively utilize the plurality of synchronization signal blocks without using additional information.

Abstract: Cell and terminal discovery methods are disclosed. A discovery method performed in a terminal may include transmitting a trigger signal; receiving a discovery signal from at least one cell which receives the trigger signal; measuring the discovery signal; and reporting a measurement result of the discovery signal to a serving cell. Therefore, cell and terminal discoveries may be performed efficiently in cellular mobile communication systems.
