Abstract
There is a need to support narrowband TDD frame structure for narrowband communications. 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. The apparatus may determine a TDD mode for narrowband communications. The apparatus may determine a TDD frame structure for the narrowband communications from a group of narrowband TDD frame structures. In one aspect, at least one common subframe in each narrowband TDD frame structure in the group of narrowband TDD frame structures may be configured as a downlink subframe. The apparatus may transmit a PSS using the at least one common subframe in the narrowband TDD frame structure determined for the narrowband communications.
