DOWNLINK TRANSMISSION IN TDD SUPPPORTING feNB-IoTs

Abstract:

Embodiments of a User Equipment (UE), generation Node-B (gNB) and methods of communication are generally described herein. The UE may receive, from a gNB, a narrowband physical downlink control channel (NPDCCII) that indicates a number of narrowband internet-of-things (NB-IoT) downlink subframes for a downlink scheduling delay of a narrowband physical downlink shared channel (NPDSCH) in one or more radio frames configured for time-division duplexing (TDD) operation. Subframes of the one or more radio frames may include uplink subframes, NB-IoT downlink subframes for downlink NB-IoT transmissions, and downlink subframes for other downlink transmissions. The UE may determine the downlink scheduling delay based on an earliest subframe for which a count of NB-IoT downlink subframes is equal to the number of NB-IoT downlink subframes indicated in the NPDCCH.
