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 .
Read moreWhat is SS burst in 5G?
SS burst is a set of SS blocks(SS/PBCH block) in a half subframe . we have seen few examples where in a half subframe there are multiple SS/PBCH blocks present . In CASE B example there are 8 SS/PBCH blocks (starting indexes 4,8,16,20,32,36,44,48) present in half frame . this set is called SS burst.
Read moreHow many slots are present in 5G subframe?
In this configuration, a subframe has 16 slots in it, it means a radio frame contains 160 slots in it. The number of OFDM symbols within a slot is 14.
Read moreWhat is resource grid in 5G?
– A resource grid is characterized by one subframe in time domain and full carrier bandwidth in the frequency domain . – There are a set of resource grids per transmission direction (uplink or downlink).
