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 narrowband communication frame structure comprising a FDD frame structure or a TDD frame structure and a narrowband TDD frame structure configuration for narrowband communications from a group of narrowband TDD frame structures configurations. The apparatus may determine one or more narrowband carriers and subframes within the one or more narrowband carriers to transmit at least one of a BCH or a SIB1 based on the narrowband communication frame structure or the TDD frame structure configuration. The apparatus may transmit a PSS, an SSS, and at least one of a BCH or an SIB1 using the narrowband TDD frame structure determined for the narrowband communications. In one aspect, a carrier used for transmitting the BCH and/or the SIB may be different than a carrier used to transmit one or more of the PSS or the SSS. In another aspect, a narr…
