The value of the PDCP sequence number ranges from 0 to 65535 . The PDCP SN window size indicates the maximum number of PDCP SDUS, not confirmed to have been successfully transmitted to the peer entity by lower layer, that can be numbered at any given time. The PDCP SN window size is configured by upper layers.
Read moreWhat is LTE protocol stack?
The protocol stack functions consist of the Medium Access Control (MAC), Radio Link Control (RLC), Packet Data Convergence Protocol (PDCP), and Radio Resource Control (RRC) . LTE is the latest generation of the 3GPP standards. The LTE standard specifies an IP-only network supporting data rates up to 150 Mbps.
Read moreWhat is RRC and PDCP?
PDCP stands for Packet Data Convergence Protocol . It is a layer of 5G NR radio protocol stack. It is placed top of the RLC Layer and below of the SDAP layer(for user plane) or RRC layer (for control plane) in the Radio Protocol Stack in 5G NR. Due to header compression functionality, it is called as convergence …

In 5G, they have introduced new RRC Stats called “RRC Inactive” to minimize latency as well as to reduce signalling load . Transitions from RRC Inactive to Connected is very quick as UE Context is stored at gNB and UE. NG signalling keep alive between gNB to AMF, GTP-U also remain alive between gNB to UPF.
