The final test

E1 What can a sensing network do that 5G could not do before?

• Carry more data on the same spectrum
• Locate a connected device more accurately
• Detect an object that is not connected to the network at all

E2 How much work does the 3GPP work plan carry for this subject?

• 18 entries, under 14 different acronyms
• One study and one work item
• 14 entries, one per acronym

E3 Which group filed the largest share of the sensing documents?

• SA1, the requirements group, with 640
• SA2, the architecture group, with 995
• RAN1, the physical-layer group, with 872

E4 What does the stage 2 specification being written now actually cover?

• Vehicles and drones together
• Every use case the original study collected
• Aerial object detection and tracking, and nothing else

E5 Of the 3492 documents, how many are change requests to a published specification?

• 2036
• 968
• 136

E6 What is TR 38.901, and why did sensing have to change it first?

• The 5G radio specification, which had to allow sensing signals
• The shared radio channel model, so that everybody's simulation of sensing starts from the same assumptions
• The sensing study report, which had to exist before the work item could open

E7 What does the radio work item promise about the phone?

• Phones need new radio behaviour for sensing
• There will be no UE impacts
• Phones become the sensing receivers

E8 What state are the security and privacy questions in?

• Settled, in an approved report
• Still a running study, with its report at 0.6.0
• Not yet opened

E9 Why is searching 3GPP for the word "sensing" the wrong way to find this work?

• The documents avoid the word
• 2053 documents say sensing and mean other work entirely
• The word only appears in titles

E10 Why is every count in this course a floor rather than a total?

• The counts were rounded down
• Only documents carrying a work item acronym were counted, and 440 documents about this subject carry none
• Some documents are confidential

E11 What can a sensing network do that the network's existing positioning cannot?

• Work out where a connected device is, more accurately
• Detect an object that is not connected to the network at all
• Carry more data on the same spectrum

E12 What does TR 22.837 say it contains?

• Use cases and potential requirements for sensing services across several industries
• Radio measurements and their accuracy
• The architecture of a sensing network

E13 What is a pCR, and why are there so many of them here?

• Proposed text for a study report, which is how a study is written
• A comment on somebody else's paper
• A change to a published specification, proposed by one company

E14 Which group filed more sensing documents than any other?

• RAN1, the physical-layer group
• SA2, the architecture group, with 995
• SA1, the requirements group

E15 What was the first radio study actually about?

• Channel modelling, so that everybody's simulation of sensing starts from the same assumptions
• Choosing frequencies for sensing
• Building sensing into base stations

E16 Which group leads the radio rule-writing for sensing?

• RAN1, which led both studies
• RAN3, the group that owns the interfaces between radio nodes
• RAN2, the radio-protocol group

E17 What does the SA1 work item say it will introduce?

• A radio measurement procedure
• An architecture for sensing
• Numbers the service must hit, and 5G system functional requirements, including configuration and authorisation

E18 Which group carries the largest share of the sensing documents?

• RAN1, with 872 across sixteen
• SA1, with 640 across eleven
• SA2, with 995 across ten meetings

E19 What state is the security study in?

• Approved, at 20.0.0
• Still running, at 0.6.0
• Not yet opened

E20 How many specifications does this work touch, and out of how many?

• 149 out of 3599
• 27 out of 3599 active 3GPP specifications
• 11 out of 27
