Patent ID: 10958337

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 mode or a TDD mode and a particular TDD frame structure for narrowband communications from a group of narrowband TDD frame structures. The apparatus may determine a periodicity, subframe number, and transmission sequence associated with a SSS based at least in part on the narrowband TDD frame structure. The apparatus may transmit the SSS using the narrowband TDD frame structure determined for the narrowband communications. In one aspect, the SSS may be transmitted in a same subframe within a frame and at a periodicity of 2 or more frames.
