According to 3GPP specifications, which of the following is not an RRC state in 5G?
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.
SSB GSCN is the center frequency number of an NR cell.
SSB GSCN is the center frequency number of an NR cell. SSB GSCN stands for 'SS block group-specific cell number' and is used to identify the center frequency of an NR cell. This value is used in combination with the operating bandwidth of the cell to determine the physical layer resource grid for the cell. As such, it is important for the correct SSB GSCN to be configured for the cell in order to ensure the correct channel coding.

In 5G NR, the SSB (Secondary Synchronization Signal Block) is used to provide the time and frequency synchronization information to the mobile devices. It is transmitted in the frequency domain and it consists of two parts: the SSB GSCN (Secondary Synchronization Signal Block - Group and Sequence Number) and the SSB MIB (Secondary Synchronization Signal Block - Master Information Block).
The SSB GSCN is a unique identifier that indicates the center frequency number of the cell. It is used to identify the cell and to determine the frequency offset of the cell with respect to the carrier frequency.
So, the statement is true, SSB GSCN is the center frequency number of an NR cell. It's worth noting that the SSB MIB contains other system information such as the system bandwidth, the transmission bandwidth configuration, and the number of symbols in a slot.
On an NSA network, the eNodeB immediately triggers the SgNB addition procedure after a UE attaches to the LTE network. If the SgNB addition fails, the eNodeB attempts to add the SgNB again until it is successful.
On an NSA network, the eNodeB immediately triggers the SgNB addition procedure after a UE attaches to the LTE network. If the SgNB addition fails, the eNodeB attempts to add the SgNB again until it is successful. The eNodeB may also trigger an SgNB addition procedure if it detects a change in its coverage area or if it detects a new SgNB or an SgNB that has been moved.
Which of the following actions are involved in NAS procedure management in 5G? (Choose all that Apply)
NAS (Non-Access Stratum) procedure management in 5G involves three specific actions: registration management, session management, and RRC connection setup. Registration management involves sending and receiving of NAS messages related to the establishment of user-network connections, such as attach and detach procedures. Session management involves sending and receiving of NAS messages related to the management of user session related information, such as security context management. RRC connection setup involves sending and receiving of NAS messages related to the establishment, modification, and release of RRC connections. RRC reestablishment is not involved in NAS procedure management in 5G.

Which of the following messages is the first message sent by a gNodeB to an AMF?
According to the official Huawei documentation, the first message sent by a gNodeB to an AMF is NGAP_INIT_UE_MSG. This message is used to initiate a connection between the gNodeB and AMF.
