In addition, the apparatus may determine a first set of subframes in the narrowband TDD frame structure used for transmitting a downlink control channel to a UE. In one aspect, a last subframe in the first set of subframes may be subframe n. Further, the apparatus may determine a second set of subframes in the narrowband TDD frame structure used for transmitting a downlink data channel to the UE. In certain aspects, a first subframe in the second set of subframes may be delayed based on k o number of subframes after the subframe n. In certain other aspects, a last subframe in the second set of subframes may be subframe n + k 0 + x. Additionally, the apparatus may signal first information associated with the k o number of subframes to the UE in a first delay field in a DCI transmission. 1406 determine a second st1 of subframes in the narrowband TDD frame structure used for transmitting a downlink data channel to the UE k s number of subframes after the first set 1408 FIG. 14A onion °nolo HE liololloiolommovoimIE (10) International Publication Number WO 2018/152027 Al 1402 determine a narrowband TDD frame structure of a group of narrowband TDD frame structures for nanowband communications 1404 determine a first set of subframes in the narrowband TDD frame structure used for transmitting a downlink control channel to a UE W O 20 18/ 152027 Al [Continued on next page] WO 2018/152027 Al MIDEDIMOMMIONER131110101101010ERVOIS EE, ES, FI, FR, GB, GR, HR, HU, IE, IS, IT, LT, LU, LV, MC, MK, MT, NL, NO, PL, PT, RO, RS, SE, SI, SK, SM, TR), OAPI (BF, BJ, CF, CG, CI, CM, GA, GN, GQ, GW, KM, ML, MR, NE, SN, TD, TG).
