Lte Network Block Diagram

This has two slightly different implementations namely s5 if the two devices are in the same network and s8 if they are in different networks.

Lte network block diagram. You can edit this network diagram using creately diagramming tool and include in your report presentation website. 3gpp nr ran can be any of the following cases new radio nr base station. Let s unpack the above block diagram of 5gs. A general resource allocation block diagram.

This has two slightly different implementations namely s5 if the two devices are in the same network and s8 if they are in different networks. Enhancement of the universal terrestrial radio access utra optimisation of the utran network architecture with hspa downlink and uplink keep utra highly competitive for several years access and bandwidth will be commodities. The interface between the serving and pdn gateways is known as s5 s8. A packet scheduler or pdsch scheduler allocates resources.

A new radio base station is known as gnodeb whereas an lte base station which is upgraded to allow connectivity with 5g core network it is known as an enhanced enodeb or a next generation enodeb. Services are the differentiator. Lte thus aims to provide a peak data rate of 100 mbps in downlink and 50 mbps in uplink respectively. Initial lte work from 2002 lte focus was on.

The figure 1 depicts block diagram of the gsm cell phone. The reason why lte is designed only for packet switching is because it aims to provide seamless internet protocol ip connectivity between user equipment ue and the packet data network pdn without any disruption to the end users applications during mobility. The ofdm symbols are grouped into resource blocks. The resource blocks have a total size of 180khz in the frequency domain and 0 5ms in the time domain.

A network diagram showing 4g lte network diagram ak 1. Radio resource manager rrm is a main component for scheduling resources. For the lte advanced network a user can be scheduled by rrm with number of carriers so in resource block allocation. 3gpp next generation radio access network ng ran.

The basic lte downlink physical resource can be seen as a time frequency grid as illustrated in figure below. They are backward compatible to 4g standards viz. Basically the lte standard only supports packet switching with its all ip network. Following diagram shows the functional split between the e utran and the epc for an lte network.

The main requirements for the new access network are high spectral efficiency high peak data rates short round trip time as well as flexibility in frequency and bandwidth. Lte long term evolution or the e utran evolved universal terrestrial access network introduced in 3gpp r8 is the access part of the evolved packet system eps.
