LTE Channel

LTE Downlink Channels Physical Downlink Shared Channel (PDSCH) Carries the DL-SCH and PCH. DL-SCH contains actual user data. Physical Downlink Control Channel (PDCCH) Informs the UE about the resource allocation of PCH and DL-SCH, and HARQ information related to DL-SCH. Carries the uplink scheduling grant. Physical HARQ Indicator Channel (PHICH)…

System Information Block LTE

System Information Block 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. Each SIB has its own job to do, which means, they are…

SCG/MCG failure handling

SCG Failure 5G NR RLF is declared separately for the MCG and for the SCG If radio link failure is detected for MCG, the UE initiates the RRC connection re-establishment procedure The following SCG failure cases are supported: SCG RLF SN change failure For EN-DC, NGEN-DC, and NR-DC, SCG configuration…

What is SON?

What is SON?

SON (Self Organizing Network) solutions can be divide into three categories: Self-Configuration. Self-optimisation Self-Healing The SON architecture can be a centralize, distribute or a hybrid solution. SELF-CONFIGURATION: This is the dynamic plug-and-play configuration of newly deployed eNBs. The eNB will by itself configure the Physical Cell Identity, transmission frequency, and…
