A first wireless communication device receives, from a second wireless communication device, a reference signal configuration of a first network of a long-term evolution (LTE) radio access technology (RAT). The first wireless communica- tion device and the second wireless communication device are associated with a second network of another RAT. The first wireless communication device receives, from the second wireless communication device, a communication signal in the second network based on the reference signal configuration of the first network. The reference signal configuration indicates at least one of a frequency tone of a reference signal of the first network, a time period of the reference signal of the first network, or a number of antenna ports associated with the reference signal of the first network. ~ill IIIIIIIIIImillIVIIIIIIIHo o Holoinumioiliflom oimIE (10) International Publication Number WO 2018/200196 Al [Continued on next page] WO 2018/200196 Al MIDEDIMOMOIDEIRDERI001010111MOHERODEVOIS AO, AT, AU, AZ, BA, BB, BG, BH, BN, BR, BW, BY, BZ, CA, CH, CL, CN, CO, CR, CU, CZ, DE, DJ, DK, DM, DO, DZ, EC, EE, EG, ES, FI, GB, GD, GE, GH, GM, GT, HN, HR, HU, ID, IL, IN, IR, IS, JO, 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.
