US 2020/0288531 A1 · ENHANCED MACHINE TYPE COMMUNICATIONS QUICK IDLE TRANSITION AFTER CONNECTION RELEASE

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.

Dependent claims

A method for wireless communications by a user equipment (UE), comprising:

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.

An apparatus for wireless communications, comprising:

a processor configured to:
determine, 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 causing the apparatus to release a radio resource control (RRC) connection;
and
cause the apparatus to release the RRC connection at a time in accordance with the determination;
and
a memory coupled with the processor.
