According to 3GPP specifications, which of the following is not an RRC state in 5G?

ARRC_IDLE

BRRC_ACTIVE

CRRC_CONNECTED

DRRC_INACTIVE

Show Suggested Answer

Suggested Answer: D

According to 3GPP specifications, the RRC states in 5G are RRCIDLE, RRCACTIVE, and RRCCONNECTED. RRCINACTIVE is not an RRC state defined in 3GPP specifications. RRCIDLE is the state when the UE is not attached to an eNB and is not actively monitoring for paging. RRCACTIVE is the state when the UE is attached to an eNB and is actively monitoring for paging. RRCCONNECTED is the state when the UE has an established RRC connection with an eNB.

The RRC is a protocol that controls the radio resources of the mobile device in a cellular network. 3GPP (3rd Generation Partnership Project) has defined several RRC states for 5G NR (New Radio) to manage the radio resources of the mobile device. These states are:

1. RRC_IDLE: The mobile device is not connected to any cell and is not actively searching for a cell to connect to. B. RRC_ACTIVE: The mobile device is connected to a cell and is actively communicating with it. C. RRC_CONNECTED: The mobile device is connected to a cell, but it's not actively communicating with it. It is in a low power state and is only listening to the paging channel for incoming calls or data.

So, the correct answer is D. RRC_INACTIVE, is not an RRC state in 5G according to 3GPP specifications. It's worth noting that the RRC state of the mobile device can change dynamically based on the network conditions, service requirements, and the mobile device's power management.

Yeah, RRC_IDLE and RRC_CONNECTED are standard.

RRC_ACTIVE is a valid state too, right?

I think RRC_INACTIVE is the odd one out!

Wait, RRC_INACTIVE? Is that even a thing?

RRC_IDLE and RRC_CONNECTED are definitely real states.

I practiced a similar question last week, and I think RRC_ACTIVE was mentioned as a state, so I’m pretty confident it’s not the answer.

I’m leaning towards D as the answer since RRC_INACTIVE doesn’t sound familiar, but I might be mixing it up with something else.

I think RRC_IDLE and RRC_CONNECTED are definitely part of the spec, but I can't recall if RRC_ACTIVE is a real state or just a practice question I saw.

I remember studying the RRC states, but I’m not sure if RRC_INACTIVE is actually defined in 5G.

I'm a bit confused on this one. I know the RRC states pretty well, but I can't quite remember if RRC_ACTIVE is a thing or not. I'll make an educated guess, but I'm not 100% sure.

Okay, let me think this through step-by-step. The 3GPP specs define the RRC states, and I know RRC_IDLE, RRC_CONNECTED, and RRC_INACTIVE are all valid. RRC_ACTIVE doesn't sound familiar, so that's probably the answer.

Hmm, this is a tricky one. I know the main RRC states are RRC_IDLE, RRC_CONNECTED, and RRC_INACTIVE, but I'm not sure if RRC_ACTIVE is also a valid 5G state. I'll have to think this through carefully.
