The present disclosure provides a solution by supporting one or more narrowband TDD frame structure(s) for narrowband communications. In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. In a further aspect, the apparatus may receive information associated with a narrowband TDD frame structure having a first contiguous uplink transmission duration. The apparatus may transmit a first portion of an uplink transmission comprising a first number of slots in the first contiguous uplink transmission duration. In certain aspects, the uplink transmission may have a duration longer than the first contiguous uplink transmission duration. omit °nolo Oil ioo ono iflo oimIE (10) International Publication Number WO 2018/160428 Al [Continued on next page] WO 2018/160428 Al MIDEDIMOMOIDEIREEMOMOHINNIEMOMMIS 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.
