Control info tunneling to increase PDCCH coverage

Abstract:

Aspects of the present disclosure provide techniques for tunneling control information associated with random access procedure (RACH) from a fifth generation (5G) new radio (NR) base station (e.g., secondary base station (SgNB)) to the user equipment (UE) via long term evolution (LTE) master base station (e.g., "MeNB") in order to extend the coverage of the SgNB. The tunneled PDCCH control information may include one or more of frequency domain resource assignment, time domain resource assignment (e.g., physical downlink shared channel (PDSCH) scheduled slot index, start symbol index and duration in the slow), and/or modulation coding scheme (MCS).
