Title: CHANNEL ACCESS FOR A MIXED NUMEROLOGY CARRIER
Abstract:
In a radio air interface, a mixed-numerology carrier is one that multiplexes orthogonal frequency division multiplexed (OFDM) waveforms that have different numerologies onto the same carrier. This disclosure provides for a sync signal (SS) enabling channel access for such a mixed-numerology carrier. In one example, a single SS, having a given numerology, supports channel access for a plurality of numerologies on the mixed-numerology carrier. In another example, a plurality of numerologies on the mixed-numerology carrier each has its own respective SS, and a single, common numerology is used for all SS's. In still another example, a plurality of numerologies on the mixed-numerology carrier each has its own respective SS, where each SS has the same numerology as the numerology for which the SS provides channel access.
