Abstract (in Japanese) (See Japanese page) 
(in English) This paper proposes fast cell search method based on estimated frequency offset for Long Term Evolution (LTE) heterogeneous networks using separate frequency spectrum between a macrocell and a small cell. It is anticipated that the high frequency spectrum will be used for outdoor or indoor small cells such as 3.5-GHz carrier frequency in the 3rd Generation Partnership Project (3GPP) technical report. When using the primary synchronization signal (PSS) and secondary synchronization signal (SSS) in the LTE radio interface, the initial cell search time for small cells with high carrier frequency becomes very long due to the false detection of the PSS received timing caused by the large frequency offset. In the proposed cell search method, we first measure the frequency error of a temperature compensated crystal oscillator (TCXO) of a set of user equipment employing the PSS signal with 2-GHz carrier frequency. Based on the estimated frequency offset for 3.5-GHz carrier frequency, we estimate the correct PSS received timing among the probable timing candidates which are estimated from the correlation between the received signal and PSS sequence replica for a small cell with 3.5-GHz carrier frequency. System-level simulation results show that by using the proposed cell search method, the initial cell search time to achieve the cell ID detection probability of 99 % is within approximately 100 ms even with the large frequency offset such as 10.5 kHz.
