摘要: A method is provided for searching for a cell in a mobile station. The method includes receiving a downlink frame including a primary synchronization signal and a secondary synchronization signal. The secondary synchronization signal contains cell identity group information and the primary synchronization signal contains cell identity information within a cell identity group. The method also includes searching for a cell using the cell identity group information in the secondary synchronization signal and the cell identity information in the primary synchronization sign.

摘要: A baseband signal generation method includes mapping frequency-domain data for a plurality of component carriers to subcarrier resources; performing a frequency shift on the frequency domain-data allocated to the subcarrier resources; generating a time-domain signal by performing IFFT on the frequency-shifted frequency-domain data using a single IFFT block; and generating a time-domain baseband signal by adding a CP to the time-domain signal.

摘要: A timing control method, performed by a first DU including a processor and a modem in a base station supporting function-splitting, includes obtaining, by the processor, first time information from a CU included in the base station; obtaining, by the processor, synchronization information with a first system based on the first time information; identifying, by the processor, a change time point of an SFN based on the synchronization information; generating, by the processor, a first timing control signal including a signal indicating a changed SFN and a first tick signal having a same periodicity as a change periodicity of the SFN when the SFN is changed; and providing, by the processor, the first timing control signal to the modem.
