What is RLC throughput in LTE?

What is RLC throughput in LTE?

2) The RLC throughput is the total data bits transmitted on the forward link at a unit of time. It includes transmissions of data PDUs, either transmitted for the first time or for retransmissions, and STATUS PDUs.

What is RLC in 4g?

Radio link control (RLC) is a layer 2 Radio Link Protocol used in UMTS, LTE and 5G on the Air interface. This protocol is specified by 3GPP in TS 25.322 for UMTS, TS 36.322 for LTE and TS 38.322 for 5G New Radio (NR). RLC is located on top of the 3GPP MAC-layer and below the PDCP-layer. RLC re-establishment.

What is RLC and MAC?

The RLC/MAC block is the basic transport unit on the air interface that is used between the mobile and the network. It is used to carry data and RLC/MAC signaling. In the previous chapter, the structure of the 52-multiframe was presented, and the concept of radio blocks was introduced.

What is RLC PDU?

An RLC PDU (Protocol Data Unit) consists of an RLC header and data. From an upper layer, RLC receives an RLC SDU (Service Data Unit). The data part of an RLC PDU is either a complete RLC SDU or an SDU segment. A single RLC PDU maps to a single MAC SDU . RLC has three transmission modes: TM , UM and AM .

What is PDCP throughput?

DL: Throughput of PDCP SDU bits in downlink for packet sizes or data bursts that are large enough to require transmissions to be split across several TTIs, by excluding transmission of the last piece of data in a data burst.

What is PDCP layer?

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 New Radio (NR). PDCP is located in the Radio Protocol Stack in the UMTS/LTE/5G Air interface on top of the RLC layer.

What is PDCP in 5G?

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 New Radio (NR). 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.

What is MAC layer in 5G?

MAC layer offers logical channels to RLC sublayer. The logical channels exist between MAC and PHY where as transport channels exist between PHY and radio layer. Hence MAC is the interface between logical channels and PHY transport channels. The figure depicts data flow through various protocol layers of 5G NR stack.

What is the role of MAC layer?

he medium access control (MAC) is a sublayer of the data link layer of the open system interconnections (OSI) reference model for data transmission. It is responsible for flow control and multiplexing for transmission medium. It controls the transmission of data packets via remotely shared channels.

What is difference between PDU and SDU?

Packets received by a layer are called Service Data Unit (SDU) while the packet output of a layer is referred to by Protocol Data Unit (PDU).

What is the full form of PDU?

A PDU, or Professional Development Unit, is a unit used to measure ongoing development within the field of project management. To maintain certification as a Project Management Professional (PMP), you will need to maintain a specific number of PDUs, earned by attending events or accomplishing courses.

What does PDCP stand for?

When is RLC a factor in network throughput?

RLC Factors in Throughput When there is big difference between PHY throughput and RLC/Above throughput Throughput in Live Network Links on Throughput Test in the field Factors influencing the throughput Throughput Test Software iperf – UDP/TCP Flooding Filezilla – FTP First thing to remember for throughput troubleshooting One sentence.

Which is higher RLC or PHY peak throughput?

Comparing section (A) and (B), (A) throughput (peak throughput) is a little bit higher at PHY but become a little bit lower at RLC Comparing section (C) and (D), (C) throughput (peak throughput) is a little bit higher at PHY but become a little bit lower at RLC Section (E) shows much bigger difference between PHY throughput and RLC throughput.

What does RLC stand for in shorthand?

This page is about the various possible meanings of the acronym, abbreviation, shorthand or slang term: RLC. Computing » Telecom — and more… Business » Occupation & Positions — and more…

What are the functions of the RLC layer?

The RLC layer also provides a similar mechanism for the transmission of RLC/MAC control messages from the BSS to the mobile. The RLC automatic repeat request (ARQ) functions support two modes of operation: RLC unacknowledged mode.
