It is used for cell re-selection as well as handover purpose.Ĭarries CDMA-2000 EVDO frequencies, CDMA-2000 neighbor cell frequencies. Carries GERAN frequencies as well as GERAN neighbor cell frequencies. carries serving UTRA and neighbor cell frequencies useful for cell re-selectionĬarries GSM neighbours information i.e. The purpose is cell reselection and handover.Ĭarries WCDMA neighbors information i.e. Other neighbor cell frequencies from other RATs.

It also defines the scheduling of the other SIBs. system bandwidthĬontains information regarding whether or not UE is allowed to access the LTE cell. This will emulate LTE MIBs and SIBs over corresponding LTE channels.Ĭarries physical layer information of LTE cell which in turn help receive further SIs, i.e. Signalling Tester model MD8430A from Anritsu can be used as LTE Base Station Emulator. System information will be changed every BCCH modification period. SIBs are transmitted using BCCH mapped on DL-SCH which in turn mapped on PDSCH. Each SI usually will have different transmission frequency and will be sent in a single sub-frame. System Information Blocks are grouped in SI containers. SI-1 transmitted every 80ms, SI-2 every 160ms and SI-3 every 320 ms. of antennas and SIB scheduling information transmittedĪlong with other information on the DL-SCH.ĭynamic 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.

The site covers articles, tutorials, vendors, terminology, source code (VHDL, Verilog, MATLAB,Labview), test and measurement, calculators, news, books, downloads and more. PHICH configuration details transmit power, no. The RF Wireless World website is a home of RF and Wireless Vendors and Resources. MIB carries useful information which includes channel bandwidth, Static part is called as MIB and is transmitted using BCHĪnd carried by PBCH once every 40ms. There are two parts in SI static part and dynamic part. This logical channel information is further carried over transport channel BCH or carried by DL-SCH. The system information is very essential and the same is broadcasted by LTE eNB over logical channel BCCH.
