The apparatus may determine a narrowband TDD frame structure of a group of narrowband TDD frame structures for narrowband communications. The apparatus may transmit a series of repetitions of a narrowband physical downlink channel using the narrowband TDD frame structure. In 00 using a first scrambling sequence. In one aspect, a second portion of repetitions from the series of repetitions may be transmitted in one one aspect, a first portion of repetitions from the series of repetitions may be transmitted in one or more first sets of downlink subframes or more second sets of downlink subframes using a second scrambling sequence.
