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 (NPDCCH) 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.

Methods, systems, and devices for wireless communications are described. In a wireless communications system, a user equipment (UE) and a base station implement reference signal modulation for conveying feedback information. In some examples, the UE may receive, from the base station, control signaling indicating to the UE to convey feedback information by modulating an uplink reference signal. The UE may receive, from the base station, a set of downlink messages. In some cases, the UE may transmit, to the base station, a set of uplink reference signals in response to receiving the downlink messages, where the set of uplink reference signals may be modulated by the UE to convey the feedback information. In some cases, the uplink reference signal may be a sounding reference signal (SRS) with embedded feedback information.

In turn, the system generates, using the downlink channel estimate, a group of downlink sector beams to be transmitted to the user equipment using the downlink channel via the portion of the respective modular antenna elements.
