    Hi,
    can anyone explain why there are 2 different in-band modes of operation for NBiot? In band same vs different PCI - what is the benefit/ use cases for same vs different PCIs?

    I posted your question on Twitter, here is the response:

    For same-PCI, at least the device can use LTE CRS for channel estimation. From the book => Cellular Internet of Things: Technologies, Standards, and Performance

    Thanks but I dont think that answers the Q. Why come up with 2 different inband modes? I am sure there was a specific benefit/use case identified when standardizing...any other input?
