The present disclosure O 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. The apparatus may determine a narrowband TDD frame structure for narrowband communications. The apparatus may also determine a PUSCH format of a group of PUSCH formats 00 for allocating at least one RU to a UE for a NPUCCH. In addition, the apparatus may allocate the at least one RU to the UE using the O determined PUSCH format. In one aspect, the RU may include one or more subcarriers in each of one or more slots.
