From Wikipedia, the free encyclopedia. Packet Data Convergence Protocol (PDCP) is specified by 3GPP in TS 25.323 for UMTS, TS 36.323 for LTE and TS 38.323 for 5G. PDCP is located in the Radio Protocol Stack in the UMTS/LTE/5G air interface on top of the RLC layer.

HFN is a timer at the next level to SFN . HFN ranges between 0 and 1023 and the value increases by 1 when SFN reaches 1023 and reset to 0. Summary of Timers. Name. Range.

PDCP is located in the Radio Protocol Stack in the UMTS/LTE/5G air interface on top of the RLC layer. PDCP provides its services to the RRC and user plane upper layers , e.g. IP at the UE or to the relay at the base station.

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 …5 Oca 2022

i) Data coming into PDCP first go through “Sequence Numbering” Procedure. It means that PDCP add “Sequence Number” to each of incoming data block . Once it add ‘Sequence Number’, it has to manage the number.

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.
