5G NR (SIB-1 TO SIB -9) System information blocks

System information blocks

 

SIB1

SIB1 contains information relevant when evaluating if a UE is allowed to access a cell and defines the scheduling of other system information.It also contains radio resource configuration information that is common for all UEs and barring information applied to the unified access control.

Signalling radio bearer: N/A

RLC-SAP: TM

Logical channels: BCCH

Direction: Network to UE

SIB2

SIB2 contains cell re-selection information common for intra-frequency, inter-frequency and/or inter-RAT cell re-selection.

 (i.e. applicable for more than one type of cell re-selection but not necessarily all) as well as intra-frequency cell re-selection information other than neighbouring cell related.

SIB3

SIB3 contains neighbouring cell related information relevant only for intra-frequency cell re-selection. The IE includes cells with specific re-selection parameters as well as blacklisted cells.

SIB4

     

SIB4 contains information relevant only for inter-frequency cell re-selection i.e. information about other NR frequencies and inter-frequency neighbouring cells relevant for cell re-selection. The IE includes cell re-selection parameters common for a frequency as well as cell specific re-selection parameters.

 SIB5

SIB5 contains information relevant only for inter-RAT cell re-selection i.e. information about E-UTRA frequencies and E-UTRAs neighbouring cells relevant for cell re-selection. The IE includes cell re-selection parameters common for a frequency.

SIB6

SIB6 contains an ETWS primary notification.

SIB7

SIB7 contains an ETWS secondary notification.

SIB8

SIB8 contains a CMAS notification.

SIB9

SIB9 contains information related to GPS time and Coordinated Universal Time (UTC). The UE may use the parameters provided in this system information block to obtain the UTC, the GPS and the local time.

NOTE:    The UE may use the time information for numerous purposes, possibly involving upper layers e.g. to assist GPS initialisation, to synchronise the UE clock.

LTE PCFICH - Physical Control Format Indicator Channel

PCFICH- Physical Control Format Indicator Channel 

 

• The Physical Control Format Indicator Channel (PCFICH) is used at the start of each one ms downlink subframe to signal the number of symbols used for the PDCCH

• The PCFICH is broadcast on the same set of antenna ports as a result of the PBCH. this implies that it area unit usually broadcast mistreatment solely antenna port zero, or transmit diversity area unit usually accustomed broadcast the PCFICH mistreatment antenna ports.

• The PCFICH occupies sixteen Resource components at intervals the first OFDMA image of each one ms downlink subframe. These sixteen Resource components area unit divided into four quadruplets. The position of these four quadruplets at intervals the first OFDMA image depends upon the downlink channel information measure and thus the Physical layer Cell Identity (PCI). associate degree example PCFICH allocation is illustrated in Figure ninety-four
• The PCFICH uses QPSK modulation thus the sixteen Resource components enable thirty-two bits
• The PCFICH transfers a bearing Format Indicator (CFI) that options a worth ranging from one to 3
• actual price = signaled price + one for the one.4 megacycle per second channel information measure actual price = signaled price for alternative channel bandwidths
• The CFI is channel coded to thirty-two bits to occupy the whole PCFICH capability
• The 1.4 megacycle per second channel information measure needs associate degree magnified variety of symbols at intervals the time domain as a result of there area unit fewer subcarriers at intervals the frequency domain, i.e. associate degree magnified variety of symbols at intervals the time domain is needed to require care of a cheap PDCCH capability
• The signaled price is determined by the linear unit lyric B radio resource management and depends upon the number of active connections, i.e. PDCCH communication will increase as a result of the number of active connections will increase
• The PCFICH represents associate degree overhead that reduces the number of Resource components out there for user plane information oo
• overhead decreases for larger channel bandwidths overhead will increase once mistreatment the extended cyclic prefix

LTE E-UTRAN FUNCTIONS AND ARCHITECTURE

E-UTRAN ARCHITECTURE

The E-UTRAN consists of eNBs:-

• Providing the E-UTRA user plane (PDCP/RLC/MAC/PHY) and control plane (RRC) protocol terminations towards the UE. 
• The eNBs are interconnected with each other by means of the X2 interface. 
• The eNBs are also connected by means of the S1 interface to the EPC (Evolved Packet Core),
• The MME (Mobility Management Entity) by means of the S1-MME and to the Serving Gateway (S-GW) by means of the S1-U. 
• The S1 interface supports a many-to-many relation between MMEs / Serving Gateways and eNBs. 

The eNB  functions: - 

• Radio Resource Management
• Radio Bearer Control,
• Radio Admission Control,
• Connection Mobility Control,
• Dynamic allocation of resources to UEs in both uplink and downlink (scheduling);
• Routing of User Plane data towards Serving Gateway;
• Measurement
• reporting configuration
