摘要： Provided are a configuration method and a transmission method of a new reference signal for frequency offset estimation in a novel wireless communication system. The method may include configuring a synchronization signal to be transmitted through a first bandwidth part of one or more bandwidth parts configured by dividing an entire bandwidth into one or more parts, allocating the one or more reference signals for estimating the frequency offset on one or more resources other than a resource for configuring the synchronization signal, and transmitting the one or more reference signals for estimating the frequency offset.

摘要： Provided are a method for transmitting and receiving control information and data between a user equipment and a base station in a short TTI frame structure. In the method, a search space of a legacy PDCCH and a search space of a sPDCCH may be separated from each other on the basis of the type of the search space or aggregation level, etc., and information on the separated search space may be signaled to the user equipment, thereby enabling the user equipment to detect a DCI while reducing the complexity of a blind decoding.
