Which system information are used in idle mode?
The system information block type 1 contains NAS system information to be used by UEs in idle mode. The system information block type 2 contains the URA identity and information for periodic cell and URA update.
What is System information Block in LTE?
System Information Blocks in LTE, SIBs carry relevant information for the UE, which helps UE to access a cell, perform cell re-selection, information related to INTRA-frequency, INTER-frequency, and INTER-RAT cell selections. In LTE there are 13 types of SIBs.
What is system information in 5G?
System information is downlink broadcast information transmitted periodically by base station. In 5G, UE reads system information for cell camping when it is powered on, for cell selection and re-selection when it is in RRC IDLE mode.
What is dedicated mode in GSM?
As soon as RRC connection is established the GSM mobile moves to dedicated mode from the idle mode state. If the mobile is supporting multi-RATs or multi modes then during the dedicated mode, mobile subscriber does the measurements from the other neighbor base stations (WCDMA, LTE, TD-SCDMA etc.).
What is difference between MIB and SIB?
Static part is called as MIB and is transmitted using BCH and carried by PBCH once every 40ms. Dynamic part is called as SIB and is mapped on RRC SI messages(SI-1,2,3,4,5,6,7,8,9,10,11) over DL-SCH and transmitted using PDSCH at periodic intervals.
What is PSS and SSS in 5G?
PSS stands for Primary Synchronization Signal, SSS stands for Secondary Synchronization Signal and ESS stands for Extended Synchronization Signal. Radio frame in 5G-TF is 10ms in duration. It has total 100 slots or 50 subframes. Each subframe consists of two consecutive slots.
What is MIB and SIB in 5G?
MIB and SIB 1 are know as Minimum System Information or MSI in 5G NR. SIB 1 alone can be referred as Remaining Minimum System Information or RMSI. In 5G NR, MIB provides all the required information to UE for decoding SIB 1. SIB 1 is cell-specific information i.e. only valid for serving cell.
What is connected mode?
Connection mode is circuit oriented. Data are transmitted in sequence over an established connection. The mode also provides an identification procedure that avoids address resolution and transmission in the data transfer phase.
What is idle mode in telecom?
Whilst in GSM or UMTS idle mode, a mobile shall implement the cell selection and reselection procedures. The mobile will be performing location area updates when necessary. The idle state in GRPS indicates that the mobile has not yet registered onto the network or is switched off.
How is SIB1 decoded?
SIB1 is transmitted on the DL-SCH (logical channel: BCCH) with a periodicity of 160 ms and variable transmission repetition periodicity within 160 ms. SIB1 is cell-specific SIB. In order for the UE to decode SIB1, all the required information is obtained from MIB. Visit 5G NR: PBCH and MasterInformation Block (MIB).
What does a UE learn after reading MIB?
After Decoding the PSS and SSS information UE have the information of Physical cell ID and not it can descramble the further information which Master information Block, which will provide the System bandwidth, Antenna configuration , System frame number.
