Bandwidth Part (BWP) is a feature introduced in 3GPP Release 15 as part of the standard for 5G New Radio (NR). The introduction of BWPs was driven by two factors: spectrum usage flexibility and power saving for the user equipment (UE). Through spectrum flexibility the carrier bandwidth and numerology in which a UE operates can be dynamically configured, thus allowing the network to simultaneously serve UEs with different service requirements (e.g., eMMB and mMTC). Furthermore, such flexibility allows UEs to monitor a bandwidth narrower than the actual carrier bandwidth, which allows for power saving. This talk focuses on the basic aspects of BWPs, it’s configuration, and some of the already identified challenges that come with its implementation. For the latter, simulation results are presented to better illustrate the advantages and disadvantages of using BWPs.


Andrea Marcano is currently working as a Research Engineer for Nokia Bell Labs France. She is part of a standardization research group focusing on radio interface architecture and protocols, where her work centers on Radio Resource Management; she has been working with BWPs since 2018.
