IP CONCEPTin Long Term Evolution

1CONTENTSEXECUTIVE SUMMARYOBJECTIVES

2EXECUTIVE SUMMARYIn the Next Generation Telecommunication (LTE), all communication devices will use IP as the identity.IP will be used to define routing from one node to others and vice versa. IP is the 3rd layer in OSI standard. Layer 3 (Network layer) is used to bring packet from one node to other using logical address (Packet Forwarder/routing).Allocation of IPV4 is limited. Therefore plan is needed and we can also divide IP network into some IP sub-network (subnetting)IPv6 contain 128 bits (IPv4 only 32 bits). As the limitation of IP allocation, IPv6 will replace IPv4.

3OBJECTIVESAfter this presentation, participants will know:

8Layer 1Downlink Physical Layer Procedures Downlink Physical Layer Procedures For E-UTRA, the following downlink physical layer procedures are especially important:Cell search and synchronization:Scheduling:Link Adaptation:Hybrid ARQ (Automatic Repeat Request)During the cell search, the UE searches for a cell and determines the frame synchronization of that cell.

Scheduling is done in the base station (eNodeB). The downlink physical control channel informs the users about their allocated time/frequency resources and the transmission formats to use. The scheduler evaluates different types of information, e.g. Quality of Service parameters, measurements from the UE, UE capabilities, buffer status.

Link adaptation is already known from HSDPA as Adaptive Modulation and Coding. Also in E-UTRA, modulation and coding for the shared data channel is not fixed, but it is adapted according to radio link quality. For this purpose, the UE regularly reports Channel Quality Indications (CQI) to the eNodeB.

Downlink Hybrid ARQ is also known from HSDPA. It is a retransmission protocol. The UE can request retransmissions of incorrectly received data packets. ACK/NACK information is transmitted in uplink, either on Physical Uplink Control Channel (PUCCH) or multiplexed within uplink data transmission.9 Uplink Physical Layer Procedures For E-UTRA, the following uplink physical layer procedures are especially important:Random accessUplink schedulingUplink link adaptationUplink timing controlHybrid ARQ

Uplink Physical Layer ProceduresThe random access may be used to request initial access, as part of handover, or to re-establish uplink synchronization. 3GPP defines a contention based and a non-contention based random access procedure.

Scheduling of uplink resources is done by eNodeB. The eNodeB assigns certain time/frequency resources to the UEs and informs UEs about transmission formats to use. Scheduling grants for the uplink are communicated to the UEs via the PDCCH in the downlink. The scheduling decisions may be based on QoS parameters, UE buffer status, uplink channel quality measurements, UE capabilities, UE measurement gaps, etc.

As uplink link adaptation methods, transmission power control, adaptive modulation and channel coding rate, as well as adaptive transmission bandwidth can be used.

Uplink timing control is needed to time align the transmissions from different UEs with the receiver window of the eNodeB. The eNodeB sends the appropriate timing-control commands to the UEs in the downlink, commanding them to adapt their respective transmit timing.

Uplink Hybrid ARQ protocol is already known from HSUPA. The eNodeB has the capability to request retransmissions of incorrectly received data packets. ACK/NACK information in downlink is sent on Physical Hybrid ARQ Indicator Channel (PHICH).1011Air Interface Physical

The three sublayers are Medium access Control(MAC)Radio Link Control(RLC)Packet Data Convergence Protocol(PDCP)

[Source: E-UTRAN Architecture(3GPP TR 25.012 ]The service access points between the physical layer and the MAC sublayer provide the transport channels. The service access points between the MAC sublayer and the RLC sublayer provide the logical channels. Radio bearers are defined on top of PDCP layer. Multiplexing of several logical channels on the same transport channel is possible.There are two levels of re-transmissions for providing reliability, namely, the Hybrid Automatic Repeat request (HARQ) at the MAC layer and outer ARQ at the RLC layer. The outer ARQ is required to handle residual errors that are not corrected by HARQ. A N-process stop-and-wait HARQ is employed that has asynchronous re-transmissions in the DL and synchronous re-transmissions in the UL. Synchronous HARQ means that the re-transmissions of HARQ blocks occur at pre-defined periodic intervals. Hence, no explicit signaling is required to indicate to the receiver the retransmission schedule. Asynchronous HARQ offers the flexibility of scheduling re-transmissions based on air interface conditions. ARQ retransmissions are based on RLC status reports and HARQ/ARQ interaction.1516Packet Data Convergence Protocol

21Internet Protocol Overview22Internet Protocol OverviewFrom Wikipedia:

TheInternet Protocol(IP) is the principalcommunications protocolin theInternet protocol suitefor relayingdatagramsacross network boundaries. This function ofROUTING enables internetworking, and essentially establishes theInternet.

Internet Protocol sends data packets with unreliable/connectionless (no warranty success or not)The responsibility is handled in upper layer.

23IP V4Communication between TCP/IP network needs identity known as IP address.

IP address contain 32 bits.IP address divided into Network ID and Host ID

32 bits IP divided into 4 parts, each part has 8 bits.Every 8 bits can be converted to decimal 0 to 255.

Dec: xxx . xxx . xxx . xxx Bit : xxxxxxxx.xxxxxxxx.xxxxxxxx.xxxxxxxxNote: IPv6 has 128 bit24IP V4 Classificationxxxxxxxx . xxxxxxxx . xxxxxxxx . xxxxxxxx

IP divided into 3 class

Class A:Network ID (8bit)Host ID (24 bit)0xxxxxxxxxxxxxxx.xxxxxxxx.xxxxxxxx Class B:Network ID (16 bit)Host ID (16 bit)10xxxxxx.xxxxxxxxxxxxxxxx.xxxxxxxx

Tujuan Subnetting:

Memadukan teknologi jaringan yang berbedaMenghindari limitasi jumlah simpul dalam satu segmenMereduksi traffic yang disebabkan oleh broadcast atau pun collision

Jaringan di bawah ini bisa kita bagi menjadi beberapa sub-jaringan dengan menggunakan router.

192.168.1.0192.168.1.1192.168.1.2192.168.1.3192.168.1.429SUBNETTING

Dari gambar sebelumnya kita akan membagi IP jaringan 192.168.1.0 menjadi 4 buah sub-jaringan.

192.168.1.0 mempunyai Network ID = 192.168.1.0Broadcast ID = 192.168 1.255Host ID = 192.168.1.1-254

Karena ada 4 subjaringan maka langkah selanjutnya adalah memecah IP tersebut menjadi 4 bagian.

192.168.1.0 =11000000.10101000.00000001.00000000Karena 4 subnet = 22 maka jumlah bit untuk subnet = 2

11000000.10101000.00000001.00000000

Simplenya 256/4 ~= 64Sehingga didapat IP jaringan 4 subjaringan:192.168.1.0192.168.1.64192.168.1.128192.168.1.192192.168.1.0192.168.1.128192.168.1.64192.168.1.19230SUBNETTING

192.168.1.0192.168.1.128192.168.1.64192.168.1.19231Exercise1. Pada jaringan Class B & C dibutuhkan 50 subnet dengan masing2 dapat mempunyai 4 hosts.Berapa subnet bits yang dibutuhkan? Bisakah?

Class B (172.16.0.0 = 10110000.00010000.00000000.00000000)Karena 50 ~ 64 = 26 maka bit subnet yang dibutuhkan adalah 6 bit.Sisa 10 bits HOST10110000.00010000.00000000.00000000

Class C (192.168.1.0 = 11000000.10101000.00000001.00000000)Karena 50 ~ 64 = 26 maka bit subnet yang dibutuhkan adalah 6 bit.Sisa 2 bits HOST11000000.10101000.00000001.00000000

2. Dari data di atas berapa subnet-mask nya?

Ingat!! Network ID use binary 1Host ID use binary 0

Maka subnet-mask adalah:Class B: 11111111.11111111.11111100.00000000 = 255.255.252.0

Class C: 11111111.11111111.11111111.11111100 = 255.255.255.252

32Exercise3. Tentukan IP subnet/sub-jaringan dari Class B & C tersebut?

For example, Abis IP is set from 10.48.x.x to 10.54.x.xFrom the CFGMML (LST IPRT) we got:

For IP Subnet=10.48.0.32, DSTMASK=255.255.255.224 (11111111.11111111.11111111.11100000) #HOST = 25 -2 = 32IP HOST/BTSIP = 10.48.0.32.0-62IP BROADCAST=10.48.0.63

41IPV6IPV6 compared to IPv4 has some advantages:

Larger address space (contain 128 bits), means 2^128 = 3.4 x 10^38 IP address can be definedMulticasting
