SSB GSCN is the center frequency number of an NR cell.
Answer(s): A
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.https://www.qualcomm.com/content/dam/qcomm-martech/dm- assets/documents/powerpoint_presentation_-_making_5g_nr_a_reality_february_2020_web.pdf Making 5G NR a Commercial Reality A unified, more capable 5G air ... https://www.qualcomm.com/content/dam/qcomm-martech/dm- assets/documents/powerpoint_presentation_-_making_5g_nr_a_reality_february_2020_web.pdf https://www.gtigroup.org/d/file/Resources/rep/2019-07-05/cbf7810256b4c312c460863fcb77bd58.pdfGTI 5G Device Power Consumption White Paper https://www.gtigroup.org/d/file/Resources/rep/2019-07- 05/cbf7810256b4c312c460863fcb77bd58.pdfIn 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.
Which of the following NR slot configurations are defined in 3GPP specifications? (Choose All that Apply)
Answer(s): A,B,C,D
1. Mixed slot is a slot configuration in which at least one downlink/uplink symbol is present, while other symbols can be flexibly configured for downlink or uplink transmission. This allows for a more efficient use of resources and better support for different types of services. B. Flexible-slot is a slot configuration in which all symbols are flexibly configured for downlink or uplink transmission. This allows for a more efficient use of resources and better support for different types of services. C. Downlink-only slot is a slot configuration in which all symbols are dedicated for downlink transmission, This configuration is mainly used for downlink-centric services such as video streaming or software downloads. D. Uplink-only slot is a slot configuration in which all symbols are dedicated for uplink transmission, this configuration is mainly used for uplink-centric services such as voice calls or video conferencing.
Which of the following channels (signals) can be used for cell measurement in NR?
Answer(s): A,B
1. DM-RS (Demodulation Reference Signals) are transmitted in the frequency domain, they are used to demodulate the downlink data and control channels, and they can be used for cell measurement such as cell identification, cell reselection, and handover. B. CSI-RS (Channel State Information Reference Signals) are also transmitted in the frequency domain, they are used to provide channel state information for downlink data and control channels, and they can be used for cell measurement such as link adaptation, beamforming and interference management. DM-RS stands for Demodulation Reference Signal and is used for channel estimation in the frequency domain. CSI-RS stands for Channel State Information Reference Signal and is used for channel estimation in the time-frequency domain. PT-RS and SSB are not channels (signals) that can be used for cell measurement in NR.
At which layer is downlink data split implemented over the NR air interface in the NSA Option 3x architecture?
Answer(s): B
Downlink data split over the NR air interface in the NSA Option 3x architecture is implemented at the medium access control (MAC) layer. The MAC layer is responsible for the management of data transmission over the air interface, including segmentation and reassembly of data packets, scheduling of transmission resources, and error correction. The other layers (RLC, PDCP, and physical) are not involved in the implementation of downlink data split.https://ec.europa.eu/research/participants/documents/downloadPublic?documentIds=080166e5a9 64aa85&appId=PPGMSPreliminary results for multi-service support in link solution adaptation https://ec.europa.eu/research/participants/documents/downloadPublic?documentIds=080166e5a9 64aa85&appId=PPGMShttps://ieeexplore.ieee.org/iel7/6287639/8948470/08998153.pdf 3GPP NR Sidelink Transmissions Toward 5G V2Xhttps://ieeexplore.ieee.org/iel7/6287639/8948470/08998153.pdf https://www.3gpp.org/ftp/Inbox/Marcoms/ICT_6_1-2.pdf journal of ict standardization - 3gpp https://www.3gpp.org/ftp/Inbox/Marcoms/ICT_6_1-2.pdfIn the Non-Stand-Alone (NSA) Option 3x architecture, the control plane functions are handled by the 4G LTE network (EPC), while the user plane functions are handled by the 5G NR network. Data split is a technique that allows to split the user plane data between the 4G LTE and 5G NR networks. The MAC (Medium Access Control) layer is responsible for controlling the access to the shared wireless medium, and it is where the downlink data split is implemented. In this architecture, the MAC layer in the 5G NR network receives the downlink data from the 4G LTE network and sends it to the physical layer for transmission.
According to 3GPP specifications, which of the following is not an RRC state in 5G?
Answer(s): 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.
