LTESniffer: An Open-Source LTE Downlink/Uplink Eavesdropper

Mobile network standards are full of acronyms. I love it.

In case you did not know, the letter Q in PHICH stands for "request".

If anyone is wondering what the parent poster is talking about — the abbreviation PHICH (which isn't mentioned in the referenced project, but is just an example of a weird mobile-network acronym) expands to "Physical channel HybridARQ Indicator Channel"; and then the embedded "ARQ" inside it, purportedly expands to https://en.wikipedia.org/wiki/Automatic_repeat_request .

Some might claim that the "Q" in "ARQ" is actually "query"; and that people who choose to expand the "Q" as "request" just have a dim view of the average person's vocabulary level.

Personally, though, I'd argue that, if you think about it, the "Q" is probably not "request" or "query", but rather just another appearance of the conventional opaque "Q" that appears in https://en.wikipedia.org/wiki/Q_code.

It's up there with the accepted Tx/Rx for transmit and receive.

At least "receive" makes more sense for Rx than "prescription"
