- derefr 2y agoIf 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 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 https://en.wikipedia.org/wiki/Q_code.

- twojacobtwo 2y agoI always saw those as parameters for some reason. Transmit(x), Receive(x).
- hnuser123456 2y agoAt least "receive" makes more sense for Rx than "prescription"

- derefr 2y agoRx actually stands for "recipe"! Which makes sense, if you remember that there used to not be such a thing as pre-compounded drugs. Rather, a prescription was literally a recipe a doctor would write out for you to give to your friendly neighbourhood compounding pharmacist, who would follow that recipe to produce a drug for you. Which in turn lends an interesting clarity to the traditional roles and competencies of "medical doctors" vs "pharmacists". In the 1800s, a trained doctor was someone who would be expected to come up with a — potentially de-novo! — drug formulation, on the spot, as a treatment for a patient; and a trained pharmacist is someone who would be expected to take your prescription, walk into a lab in the back of their shop, and come out having converted that — potentially never-before-encountered — drug formulation into something you could put in your mouth. If the active ingredient was something unusual, they would even be expected to synthesize it themselves! (Which explains why we used to call pharmacists "chemists". They were!)
- withinboredom 2y agoInterestingly, compounding pharmacists still exist. When my son was less than a year old, he needed some medicine, but there was nothing we could buy over the counter for his weight. So, the doctor literally wrote the recipe down and sent us to a compounding pharmacist across town.
- froh 2y agoI thought you were kidding me... here is the letter Q in PHICH: https://github.com/srsran/srsRAN_4G/blob/master/lib/src/phy/phch/phich.c#L73C23-L73C40 https://github.com/srsran/srsRAN_4G/blob/master/lib/src/phy/... as the sibling comment states, q is the reQuest
- ajsnigrutin 2y agoMeh, this is not rare. In colors (design, printing,...), the "K" in CMYK stands for "blacK"
- selectodude 2y agoThe K in CMYK stands for “Key”, which is the backing plate, usually black inked.
- BenjiWiebe 2y agoNotice there is no Q in PHICH even.
