Abstract: An operating method of a terminal in a wireless communication system including a cell and the terminal includes receiving an external signal including a synchronization signal block (SSB) from the cell, the SSB including a primary synchronization signal (PSS), a secondary synchronization signal (SSS), and a physical broadcast channel (PBCH), obtaining a cell identification number of the cell using the PSS and the SSS, determining a plurality of decoding priorities of a plurality of candidate indexes of the SSB, and performing decoding on the PBCH based on the plurality of decoding priorities.

Abstract: A device may receive a first synchronization signal including at least one first synchronization signal block (SSB) from a serving base station and a second synchronization signal including at least one second SSB from a neighboring base station, where the second synchronization signal overlaps a slot through which data is transmitted from the serving base station. Additionally, the device may measure a first received power and a received reference signal received power (RSRP) of each of the first synchronization signal and the second synchronization signal received on the slot. The device may calculate an effective RSRP corresponding to at least one additional SSB received from the serving base station, the effective RSRP calculated based on a correlation power, where the correlation power is based on a cross correlation between the received RSRP, the first received power, the data, and the at least one additional SSB.

Abstract: An operating method of a terminal performing a cell search using first and second memories for buffering input samples includes detecting a first primary synchronization signal (PSS) group from a first input sample group while buffering the first input sample group in the first memory in a first interval. While buffering a second input sample group in the second memory in a second interval following the first interval, the method detects a second PSS group from the second input sample group, and a first secondary synchronization signal (SSS) group corresponding to the first PSS group from the first input sample group. While buffering a third input sample group in the first memory in a third interval following the second interval, the method detects a third PSS group from the third input sample group, and a second SSS group corresponding to the second PSS group from the second input sample group.
