A base station apparatus performs an LBT procedure at a 1-1 in beginning of frames and transmits a plurality of repetitions of a transmission. When the plurality of repetitions span multiple frames GO and the LBT procedure is not successful for a first frame, the base station drops or postpones at least one repetition in the first frame .—..... © until a second frame when the LBT procedure is successful. A UE receives the plurality of repetitions and may combine a plurality of GO repetitions across multiple frames. The UE may determine whether the base station drops the at least one repetition in the first frame 1-1 c:::: , or postpones the at least one repetition in the first frame until a second frame. ei C [Continued on next page] WO 2018/085154 Al 111111111111111111101010111110111110111011111111111111111111111101111111110111111111111 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.
