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.
Read moreWhat is PDCP discard timer?
A PDCP layer sets a timer and discards a PDCP SDU upon expiration of the timer . The timer may be set upon receiving the PDCP SDU from an upper layer or upon submitting the PDCP SDU to a lower layer for transmission. The timer and a radio link control (RLC) discard timer may be coordinated.

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.
