REFERENCE SIGNAL PRESENCE AND/OR BANDWIDTH DETERMINATION IN NARROWBAND SYSTEMS

摘要

Aspects of the present disclosure provide techniques and apparatus for determining presence and/or bandwidth of reference signals (RS) in systems that utilize narrowband regions of wider system bandwidth for wireless communications, such as enhanced machine type communication(s) (eMTC) systems and/or narrowband Internet-of-Things (NB-IoT) systems. Aspects provide a method for wireless communications by a user equipment (UE) operating in a narrowband region of a wider system bandwidth. The method generally includes determining at least one of: a presence of one or more RS in a subframe or a bandwidth of the one or more RS, wherein the bandwidth of the one or more RS is greater than or equal to a bandwidth of the narrowband region; and monitoring for the one or more RS in the subframe based on the determination.
