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 k0 number of subframes after the subframe n. In certain other aspects, a last subframe in the second set of subframes may be subframe n+k0+x. Additionally, the apparatus may signal first information associated with the k0 number of subframes to the UE in a first delay field in a DCI transmission."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Narrowband time-division duplex frame structure for narrowband communications","description":"A method, computer-readable medium, and apparatus are provided.
