Abstract: Aspects of the present disclosure provide techniques to enable random access channel (RACH) enhancements over previously known techniques for narrowband (e.g., narrowband Internet-of-Things (NB-IoT) ) communications systems. An example method includes receiving a first allocation of frequency resources for a first period for receiving a downlink (DL) transmission or transmitting an uplink (UL) transmission, and postponing transmission of a random access channel (RACH) by the UE during the period.

Abstract: Aspects of the present disclosure provide techniques to enable enhanced machine type communication (s) (eMTC) and/or narrowband Internet-of-Things (NB-IoT) devices to transition to idle mode after releasing a connection, such as a radio resource control (RRC) connection, more quickly than with previously known techniques. An example method includes determining, based on an indication received in a narrowband signal on a narrowband region of a bandwidth comprising a plurality of narrowband regions, whether to wait for a delay period, determined based on a configuration received from a network entity, before releasing a radio resource control (RRC) connection and releasing the RRC connection at a time in accordance with the determination.
