Electricity metering data exchange - The DLMS/COSEM suite - Part 8-5: The narrow-band OFDM PLC profile for G3-PLC networks

This Technical Specification specifies the EN 62056 DLMS/COSEM communication profile for metering purposes based on the Recommendations ITU-T G.9901: Narrowband Orthogonal Frequency Division Multiplexing Power Line Communication Transceivers – Power Spectral Density Specification and ITU-T G.9903 Narrow-band orthogonal frequency division multiplexing power line communication transceivers for G3-PLC networks, an Orthogonal Frequency Division Multiplexing (OFDM) Power Line Communications (PLC) protocol.
The physical layer provides a modulation technique that efficiently utilizes the allowed bandwidth within the CENELEC A band (3 kHz – 95 kHz) (although ITU-T G.9903 defines the protocol for CENELEC B, ARIB and FCC bands as well), thereby allowing the use of advanced channel coding techniques. This combination enables a very robust communication in the presence of narrowband interference, impulsive noise, and frequency selective attenuation.
The medium access control (MAC) layer allows the transmission of MAC frames through the use of the power line physical channel. It provides data services, frame validation control, node association and secure services.
The 6LoWPAN adaptation sublayer enables an efficient interaction between the MAC and the IPv6 network layers. The IPv6 network protocol; the latest generation of IP (Internet Protocol), widely opens the range of potential applications and services for metering purposes (but not limited to metering purposes).
The transport layer, the application layer and the data model are as specified in the EN 62056 DLMS/COSEM suite.

1 Scope
This Technical Specification specifies the EN 62056 DLMS/COSEM communication profile for
metering purposes based on the Recommendations ITU-T G.9901: Narrowband Orthogonal
Frequency Division Multiplexing Power Line Communication Transceivers – Power Spectral
Density Specification and ITU-T G.9903 Narrow-band orthogonal frequency division
multiplexing power line communication transceivers for G3-PLC networks, an Orthogonal
Frequency Division Multiplexing (OFDM) Power Line Communications (PLC) protocol.
The physical layer provides a modulation technique that efficiently utilizes the allowed
bandwidth within the CENELEC A band (3 kHz – 95 kHz) (although ITU-T G.9903 defines the
protocol for CENELEC B, ARIB and FCC bands as well), thereby allowing the use of
advanced channel coding techniques. This combination enables a very robust communication
in the presence of narrowband interference, impulsive noise, and frequency selective
attenuation.
The medium access control (MAC) layer allows the transmission of MAC frames through the
use of the power line physical channel. It provides data services, frame validation control,
node association and secure services.
The 6LoWPAN adaptation sublayer enables an efficient interaction between the MAC and the
IPv6 network layers. The IPv6 network protocol; the latest generation of IP (Internet Protocol),
widely opens the range of potential applications and services for metering purposes (but not
limited to metering purposes).
The transport layer, the application layer and the data model are as specified in the EN 62056
DLMS/COSEM suite.

5 Overview
The present technical specification constitutes the specification for ITU-T G.9903
communication profile for metering purposes based on OFDM and DLMS/COSEM.
This technical specification has been developed to meet the following aims:
• Robustness: the communication profile shall be suited to severe powerline environments;
• Performance: it embeds adaptive modulation to use the proper modulation according to
the quality of the link;
• Simplicity: it shall be simple to implement, install (Plug and Play), operate and maintain;
• Flexibility: it shall be compatible with diverse applications and network topologies;
• Security: it shall offer a secure environment for the promotion of Value Added services;
• Openness: it shall be based on open standards in order to support multi-supplier
solutions;
• Scalability: it shall support a very large range of devices (from 2 up to 2000 nodes in the
same PAN);
• Future proof: it shall be able to support future applications.
6 Targeted communication environments
The DLMS/COSEM narrow-band OFDM PLC profile for G3 networks is intended for remote
data exchange on Neighbourhood Networks (NN) between Neighbourhood Network Access
Points (NNAP) and Local Network Access Points (LNAPs) or End Devices using OFDM
technology over the low voltage electricity distribution network as a communication medium.
The functional reference architecture is shown in Figure 1.

Figure 1 – Communication architecture
End devices – typically electricity meters – comprise application functions and communication
functions. They may be connected directly to the NNAP via the C interface, or to an LNAP via
an M interface, while the LNAP is connected to the NNAP via the C interface. The LNAP
function may be co-located with the metering functions.
A NNAP comprises gateway functions and it may comprise concentrator functions. Upstream,
it is connected to the Metering Head End System (HES) using suitable communication media
and protocols.
End devices and LNAPs may communicate to different NNAPs, but to one NNAP only at a
time. From the PLC communication point of view, the NNAP acts as the PAN coordinator
while end devices and LNAPs act as PAN devices.
NNAPs and similarly LNAPs may communicate to each other, but this is out of the scope of
this Technical Specification, which covers the C interface only.
When the NNAP has concentrator functions, it acts as a DLMS/COSEM client. When the
NNAP has gateway functionality only, then the HES plays the role of a DLMS/COSEM client.
The end devices or the LNAPs play the role of DLMS/COSEM servers.
A mixed architecture is also possible, i.e. both the HES and the NNAP can act as a client.

Following this reference model, a profile can be identified using the G3 PHY, data link layer
as lower layers on one hand, and the DLMS/COSEM Application layer and the COSEM object
model on the other hand.

8 ITU-T G.9903 communication layers
8.1 Physical Layer (PHY)
8.1.1 Overview
This layer provides the interface between the equipment and the physical transmission
medium that is the powerline. It transmits and receives MPDUs between neighbour nodes.
The physical layer uses OFDM modulation in the CENELEC A-band. This band covers the
frequency range from 3 kHz up to 95 kHz and its use is restricted to electricity suppliers and
their licensees. The OFDM signal uses a frequency bandwidth of 54,6875 kHz located on the
high end of the CENELEC A-Band.
For more details about the G3-PLC PHY layer, see ITU-T G.9903, Clause 7.
8.1.2 G3-PLC PHY data plane services
G3-PLC PHY data plane services are generated / used by the MAC layer entity whenever
data have to be transmitted to / received from (a) peer MAC entity(ies) using the PHY
transmission procedures. See ITU-T G.9903, 7.17.1. They are the following:
• PD-DATA.request: allows the MAC layer entity to request the transmission of an MPDU to
a peer MAC entity;
• PD-DATA.confirm: allows the PHY layer entity to confirm the end of the transmission of an
MPDU;
• PD-DATA.indication: allows the PHY layer entity to transfer a PPDU from the PHY to the
local MAC layer;
• PD-ACK.request: allows the MAC layer entity to send an ACK PHY frame to the peer MAC
entity via the local PHY layer;
• PD-ACK.confirm: allows the PHY layer entity to confirm the end of the transmission of an
ACK PHY frame;
• PD-ACK.indication: allows the PHY layer entity to indicate that an ACK PHY frame has
been received from the peer MAC frame.
8.1.3 G3 PHY management plane services
G3 PHY management plane services are used to manage the physical layer by the MAC
layer. See ITU-T G.9903, 7.17.2. They are described below:
• PLME_SET: allows the MAC layer entity to set the characteristics (power, modulation…) to
use for the next PHY packet to transmit;
• PLME_GET: allows the MAC layer entity to get physical information from the last physical
packet received: channel characteristics (power, modulation…), the signal noise ratio
(SNR) global or per each carrier and the phase differential with the neighbour;
• PLME_SET_TRX_STATE: allows the MAC layer entity to change the mode of the PHY
layer either in transmission or reception mode;
• PLME_CS: allows the MAC layer entity to get media status using carrier sense (either idle
or busy). This information is used by the CSMA-CA algorithm implemented in the MAC
layer.
8.2 MAC layer
8.2.1 Overview
A G3-PLC subnetwork is a mesh network with two types of nodes, the PAN Coordinator and
PAN devices. The PAN coordinator is at the root of the mesh network and acts as the master
node that provides the subnetwork with connectivity. There is one PAN coordinator in a
subnetwork. Any other subnetwork node is a PAN device.
The PAN Coordinator manages the G3-PLC subnetwork resources and connections. This
specific PAN device is initially the subnetwork itself and all other nodes should follow a
registration process to enrol themselves on the subnetwork.

---------------------- Page: 14 ----------------------

SIST-TS CLC/TS 52056-8-5:2015
– 13 – CLC/TS 52056-8-5:2015

PAN devices start in a “non-associated” state and they try to find directly a PAN Coordinator
or a neighbour PAN device to register to the G3-PLC subnetwork. Once done, the PAN device
receives a short MAC address and may automatically serve as a router for other PAN devices
which wants to connect to the subnetwork.
The functions offered by the MAC layer are:
• Channel Access implementation using the CSMA/CA algorithm;
• Inter-frame (IFS) spacing management;
• Management of the priority access to the channel following the type of MPDU to transmit;
• Automatic Repeat Request (ARQ) mechanism between nodes based on acknowledged
and unacknowledged retransmission;
• MAC packet (MPDU) segmentation and reassembly to / from PHY layer;
8.2.2 G3-PLC MAC Data Services
G3 MAC data plane services are generated / used by the Adaptation layer entity whenever
data have to be transmitted to / received from (a) peer Adaptation entity(ies) using the MAC
transmission procedures. See ITU-T G.9903, 9.3.3. They are the following:
• MCPS-DATA: is used to send or receiving unicast, multicast or broadcast data.
8.2.3 G3-PLC MAC Management services
G3-PLC MAC management plane services are generated / used by the local Adaptation layer
entity to the local MAC entity. See ITU-T G.9903, 9.3.3. They are the following:
• MLME-BEACON-NOTIFY: allows the MAC layer entity to send to the Adaptation layer
entity information received from a neighbour during a neighbourhood discovery;
• MLME-GET: allows the Adaptation layer entity to request value about a given
configuration PIB attribute from the MAC layer entity;
• MLME-RESET: allows the Adaptation layer entity to reset the MAC layer entity to its
default configuration values;
• MLME-SCAN: uses by the Adaptation layer entity to initiate an active channel scan to
discover the neighbourhood G3-PLC network;
• MLME-COMM-STATUS: allows the local MAC layer entity to inform the Adaptation layer
entity about the status of a communication;
• MLME-SET: allows the Adaptation layer entity to set value about a given configuration PIB
attribute from the MAC layer entity;
• MLME-START: allows the Adaptation layer entity to initiate a new G3-PLC subnetwork
(new PAN). This primitive is only used by the PAN Coordinator;
• MLME-SYNC-LOSS: allows the MAC layer entity to indicate to the Adaptation layer entity
a detection of an alternate PAN network (i.e. another G3-PLC subnetwork managed by
another PAN Coordinator).
8.3 Adaptation layer
8.3.1 Overview
The following description is based on ITU-T G.9903, 9.4.
The functions offered by the IPv6 Adaptation layer are:
• Bootstrapping and Authentication process;
• UDP and IPv6 header compression;
• LOADng Mesh Routing protocol (may be disabled);
• IPv6 Address auto-configuration;
• Fragmentation and reassembly of IPv6 packet;
• G3-PLC subnetwork management;

• Unicast, multicasting and broadcasting.
8.3.2 G3-PLC Adaptation Data Services
G3-PLC Adaptation data plane services are generated / used by the application layer entity
whenever data have to be transmitted to / received from (a) peer application entity(ies) using
the Adaptation transmission procedures. See ITU-T G.9903, 9.4.6.1. It is the following:
• ADPD-DATA: is used to send or receiving unicast, multicast or broadcast data.
8.3.3 G3-PLC Adaptation Management Services
G3-PLC Adaptation management plane services are generated / used by the local application,
layer entity to the local Adaptation layer entity. See ITU-T G.9903, 9.4.6.2. They are the
following:
• ADPM-DISCOVERY: allows the application layer to request to Adaptation layer to scan for
G3-PLC subnetwork in its POS;
• ADPM-NETWORK-START: allows the application layer entity to request the starting of a
new G3-PLC subnetwork. It shall only be invoked by a device designated as the PAN
Coordinator of the new G3-PLC subnetwork;
• ADPM-NETWORK-JOIN: for a PAN device, allows the application to request to register to
a specific G3-PLC network (identified by its PAN identifier). On other hand, for the PAN
Coordinator, this primitive is used to inform the application about a new request of
registering;
• ADPM-NETWORK-LEAVE: allows the application layer of a PAN device to remove itself
from the G3-PLC subnetwork. This primitive is not applicable for the PAN Coordinator;
• ADPM-RESET: allows the application layer to request a reset of the G3-PLC transport
layer (including the Adaptation and MAC layers);
• ADPM-GET: allows the application layer to request value about a given configuration PIB
attribute of the Adaptation and MAC layers entities;
• ADPM-SET: allows the application layer to set value about a given configuration PIB
attribute of the Adaptation and MAC layers entities;
• ADPM-NETWORK-STATUS: allows the application layer of a PAN
