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 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.
Read moreWhat is the use of PDCP protocol?
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.
Read moreWhat is 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 …5 Oca 2022
Read moreWhat is protocol and protocol stack?
The protocol stack or network stack is an implementation of a computer networking protocol suite or protocol family . Some of these terms are used interchangeably but strictly speaking, the suite is the definition of the communication protocols, and the stack is the software implementation of them.
Read moreWhat is cellular 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 moreWhy protocol stack is required?
The protocol stack is used to allow the combination of different protocols that each set the boundaries for a number of network activities . … These functions are all separated into separate ‘layers’ of data that all require a protocol to be transferred.
