A UE r
42、eceives the following synchronization signals (SS) in order to perform cell search: the primary synchronization signal (PSS) and secondary synchronization signal (SSS) as defined in 4, TS 38.211. A UE assumes that reception occasions of a physical broadcast channel (PBCH), PSS, and SSS are in consec
43、utive symbols, as defined in 4, TS 38.211, and form a SS/PBCH block. The UE assumes that SSS, PBCH DM-RS, and PBCH data have the same EPRE. The UE may assume that the ratio of PSS EPRE to SSS EPRE in a SS/PBCH block in a corresponding cell is either 0 dB or 3 dB. If the UE has not been provided dedi
44、cated higher layer parameters, the UE may assume that the ratio of PDCCH DMRS EPRE to SSS EPRE is within -8 dB and 8 dB when the UE monitors PDCCHs for a DCI format 1_0 with CRC scrambled by SI-RNTI, P-RNTI, or RA-RNTI. For a half frame with SS/PBCH blocks, the first symbol indexes for candidate SS/
45、PBCH blocks are determined according to the subcarrier spacing of SS/PBCH blocks as follows, where index 0 corresponds to the first symbol of the first slot in a half-frame. - Case A - 15 kHz subcarrier spacing: the first symbols of the candidate SS/PBCH blocks have indexes of 2, 8 + 14*n. For carri
46、er frequencies smaller than or equal to 3 GHz, n=0, 1. For carrier frequencies larger than 3 GHz and smaller than or equal to 6 GHz, n=0, 1, 2, 3. - Case B - 30 kHz subcarrier spacing: the first symbols of the candidate SS/PBCH blocks have indexes 4, 8, 16, 20 + 28*n. For carrier frequencies smaller
47、 than or equal to 3 GHz, n=0. For carrier frequencies larger than 3 GHz and smaller than or equal to 6 GHz, n=0, 1. - Case C - 30 kHz subcarrier spacing: the first symbols of the candidate SS/PBCH blocks have indexes 2, 8 + 14*n. For carrier frequencies smaller than or equal to 3 GHz, n=0, 1. For ca
48、rrier frequencies larger than 3 GHz and smaller than or equal to 6 GHz, n=0, 1, 2, 3. - Case D - 120 kHz subcarrier spacing: the first symbols of the candidate SS/PBCH blocks have indexes 4, 8, 16, 20 + 28*n. For carrier frequencies larger than 6 GHz, n=0, 1, 2, 3, 5, 6, 7, 8, 10, 11, 12, 13, 15, 16
49、, 17, 18. - Case E - 240 kHz subcarrier spacing: the first symbols of the candidate SS/PBCH blocks have indexes 8, 12, 16, 20, 32, 36, 40, 44 + 56*n. For carrier frequencies larger than 6 GHz, n=0, 1, 2, 3, 5, 6, 7, 8. From the above cases, the applicable ones for a cell depend on a respective frequency band, as provided in 8-1, TS 38.101-1 and 8-2, TS 38.101-2. A same case applies for all SS/PBCH blocks on the cell. The candidate SS/PBCH blocks in a half frame are indexed in an ascending order in time from 0 to 1L . A
