Abstract
A wireless communication device including processing circuitry configured to generate first synchronization signal measurement values by combining sets of correlation values, the sets of correlation values being based on a reception signal, and each of the sets of correlation values having a number of correlation values equal to a first accumulation count, determine whether a valid synchronization signal measurement value is detected among the first synchronization signal measurement values based on a criterion, determine a frequency corresponding to the first valid synchronization signal measurement value as a synchronization frequency in response to determining the valid synchronization signal measurement value is detected, determine a second accumulation count in response to determining the valid synchronization signal measurement value is not detected, generate second synchronization signal measurement values based on the second accumulation count, and perform an initial access operation for synchronization with a base station using the synchronization frequency.
