Some examples provide for identifying a primary synchronization signal (PSS) sequence of a synchronization subframe, determin- ing, for the synchronization subframe, an extended syn- chronization signal (ESS) sequence based at least in part on the PSS sequence and transmitting the synchroniza- tion subframe. Other examples provide for generating an ESS sequence for a synchronization subframe to be com- municated to a UE, scrambling the ESS sequence based at least in part on cell-specific information associated with the base station and transmitting, to the UE, the 115-a scrambled ESS sequence in the synchronization sub - frame. 200 0 WO 2017/165080 Al MIDEDIMOMOIDIONOIDEMOMMEMEIRMONMEHOIMIE (81) Designated States (unless otherwise indicated, for every kind of national protection available): AE, AG, AL, AM, TJ, TM), European (AL, AT, BE, BG, CH, CY, CZ, DE, DK, EE, ES, FI, FR, GB, GR, HR, HU, IE, IS, IT, LT, AO, AT, AU, AZ, BA, BB, BG, BH, BN, BR, BW, BY, LU, LV, MC, MK, MT, NL, NO, PL, PT, RO, RS, SE, BZ, CA, CH, CL, CN, CO, CR, CU, CZ, DE, DJ, DK, SI, SK, SM, TR), OAPI (BF, BJ, CF, CG, CI, CM, GA, DM, DO, DZ, EC, EE, EG, ES, FI, GB, GD, GE, GH, GM, GT, HN, HR, HU, ID, IL, IN, IR, IS, JP, KE, KG, KH, KN, KP, KR, KW, KZ, LA, LC, LK, LR, LS, LU, LY, MA, MD, ME, MG, MK, MN, MW, MX, MY, MZ, NA, NG, NI, NO, NZ, OM, PA, PE, PG, PH, PL, PT, QA, RO, RS, RU, RW, SA, SC, SD, SE, SG, SK, SL, SM, ST, SV, SY, TH, TJ, TM, TN, TR, TT, TZ, UA, UG, US, UZ, VC, VN, ZA, ZM, ZW.
