When UE is power up it is in Disconnected mode/Idle mode, It can move RRC connected with initial attach or with connection establishment. If there is no activity from UE for a short time, It can suspend its session by moving to RRC Inactive and can resume its session moving to RRC connected mode .19 Kas 2017
Read moreWhat does RRC mean in LTE?
3GPP LTE RRC (Radio Resource Control ) Layer.
Read moreWhat is the function of RRC?
The RRC protocol performs the following functions: broadcasting information system, control of the connection, control of the radio bearer, control of handover, transfer of measurement reports .
Read moreWhat is RRC in networking?
Summary. Radio resource control (RRC) is the highest layer in the control plane of the access stratum (AS) . It also transfers messages of the non-access stratum (NAS), which is located above the RRC layer.
Read moreWhat is cell search in 5G?
Cell search is the procedure by which a UE acquires time and frequency synchronization with a cell and decode the Cell ID of that cell . In 5G NR, Cell search concept is similar to what it is in LTE in terms of decoding Primary Sync Signal (PSS) and Secondary Sync Signal (SSS) to the Physical Cell ID (PCI).28 Tem 2019
Read moreWhat is cell search in LTE?
Cell searching is a procedure in which a UE achieves time and frequency synchronization with a cell, obtains the physical cell identifier (PCI), and learns the signal quality and other information about the cell based on the PCI. A UE performs cell search on all frequencies before selecting or re-selecting to a cell.
Read moreWhat is purpose of SSS in 5G?
Cell search is the procedure for a UE to acquire time and frequency synchronization with a cell and to detect Physical layer Cell ID (PCI) of the cell .
