5 Conformance
Conforming entities implement:
— both talker and listener;
— listen before talk (LBT) for both talker and listener;
— the capability to execute association on FDC2 and to communicate on (FDC0 and FDC1), (FDC3 and
FDC4), or (FDC0, FDC1, FDC3 and FDC4);
— the capability for talkers and listeners to use any of the 8 TDS on an FDC;
— both full duplex and broadcast communication, and pass the tests specified in Annex A.
6 Architecture
The protocol architecture of CCCC follows ISO/IEC 7498-1 as the basic model. CCCC devices communicate
through mediators, such as conductive and dielectric materials.
Plate-electrodes for CCCC device E and F are equivalent to the reference plate-electrode assembly.
The plate-electrode A faces to the imaginary point at infinity and the plate-electrode B faces to the
mediator. The plate-electrode C faces to the mediator and the plate-electrode D faces to the imaginary
point at infinity. See Figure 1.
Figure 2 is the equivalent circuit of Figure 1. The voltage of X is the potential of the point at infinity. The
voltage of Y is the potential of the point at infinity. It is deemed that the potential of X and Y is identical.
Therefore, X and Y is imaginary short. Consequently, devices E and F are able to send and receive signal.
Regarding the information transfers from CCCC devices E to F, device E changes the voltage between
plate-electrode A and B. It changes the electric charge between plate-electrode B and the mediator.
2 © ISO/IEC 2021 – All rights reserved

The change in electric charge affects device F by the capacitive coupling between plate-electrode C and
mediator. Plate-electrodes A and B and plate-electrodes C and D have potential differences of reverse
polarity; therefore, device F senses the information as changes in voltage between plate-electrode C
and D.

Figure 2 — Equivalent circuit
Information transfer between CCCC devices E and F takes place by synchronous communication, see
subclause 13.1. Subclause 8.2.1 specifies five frequency division channels (FDC) by division of the
centre frequency. Each FDC consists of a sequence of time-segments. Each time-segment consists of
eight time division slots (TDS) for time division multiple-access, see Clause 12. Peers use the listen
before talk (LBT) procedure in subclause 13.1 to ascertain that a TDS is not occupied. The TDSs are
negotiated using the association procedure specified in Clause 14.
Subclauses 15.1 and 15.2 specify full duplex and broadcast communication respectively. In full duplex
communication, talkers and listeners exchange P-PDUs (see Clause 9) by synchronous communication.
In broadcast communication, talkers broadcast P-PDUs and listeners receive P-PDUs without
acknowledgment.
Length information and CRC is added to the SDU to construct a PHY data unit (P-DU), see Clause 10. The
sender segments the P-DU into P-PDUs. The receiving entity reassembles the P-PDUs into the P-DU, see
Clause 11, and forwards the SDU to its PHY user as illustrated in Figure 3.

Figure 11 — Mapping of a P-PDU and a TDS
This document specifies full duplex and broadcast communication. A TDS is used for unidirectional
communication. A full duplex channel consists of two TDSs and one TDS is used for broadcast
communication.
The TDS may be either fixed by configuration or be negotiated.
Talkers may either use fixed configured TDS(s) on FDC1 or FDC3 or alternatively negotiate using TDS(s)
on FDC1 or FDC3 using the association procedure. Talkers that select FDC0 or FDC4 shall negotiate TDS
using the association procedure in Clause 14.
Before using a TDS, entities shall use LBT and synchronisation.
13 LBT and synchronisation
13.1 LBT
During LBT, entities shall listen for 576 T on the selected FDC to seek a free TDS. A TDS is occupied
when the entities receive a correct P-PDU.
13.2 Synchronisation
If all TDSs on the FDC that the talker selects are found to be free using LBT, then that talker shall
generate the TDS timing on its selected FDC. Otherwise the talkers shall synchronise to the TDS timing
on the FDC using LBT. Listeners shall always synchronise to the TDS timing on the FDC using LBT.
12 © ISO/IEC 2021 – All rights reserved

14 Association procedure
Talkers use the association procedure to negotiate the communication TDS(s). During this procedure,
talkers and listeners exchange the P-PDUs on 2 full duplex TDS in FDC2, in the following steps:
1) Talker selects a free association TDS in the range from 0 to 3 in FDC2, using LBT.
2) Talker selects (1 for broadcast and 2 for full duplex) free slot(s) in an FDC other than FDC2, using
LBT.
3) Talker sends association request 1 P-PDU specified in Table 3 on the association TDS from step
1 with attribute (00)b, sequence number (00)b and FDC/TDS(s) from step 2 and the selected
communication mode.
4) Listener sends association response 1 P-PDU specified in Table 4 on the association TDS number +
4 with attribute (01)b, sequence number (01)b and random number.
5) Talker sends association request 2 P-PDU specified in Table 4 on the association TDS from step 1
with attribute (01)b, sequence number (10)b and the random number from association response 1.
6) Listener sends association response 2 P-PDU specified in Table 3 on the association TDS number +
4 with attribute (00)b, sequence number (11)b and FDC/TDS(s) from association request 1.
7) Peers attempt communication as specified in Clause 15 on the FDC/TDS(s) from association request
1.
8) If the FDC/TDS(s) from association request 1 are occupied peers may repeat this association
procedure.

15 Communication
15.1 General
Entities exchange P-PDUs (see Clause 11) using either full duplex or broadcast communication.
Entities shall send Null P-PDUs when there is no P-DU (see Clause 10) pending until the PHY user stops
communication.
15.2 Full duplex communication
See subclause 9.7.1 for the rules on the sequence numbering.
The sender shall resend the current P-PDU until it is acknowledged. See subclause 9.7.2.
The next P-PDU shall have a sequence number of the (last received sequence number + 1) modulo 4.
Figure 13 illustrates full duplex communication without any errors.

Figure 14 — Example flow of full duplex communication with some resending
15.3 Broadcast communication
Broadcast communication is unidirectional and unacknowledged.
For broadcast communication, the talker (hereafter referred to as broadcaster) shall use the LBT
procedure in subclause 13.1 to find a free TDS on FDC0 or FDC4.
Any numbers of receivers may receive broadcasted P-PDUs.
See subclause 9.7.1 for the rules on the sequence numbering.
The broadcaster may repeatedly send identical P-PDUs. The next P-PDU shall have a sequence number
of the (last sent sequence number + 1) modulo 4.
NOTE Repeating identical P-PDUs can increase communication robustness.
Figure 15 illustrates broadcast communication flow. In this example, the broadcaster sends identical
P-PDUs in 2 time-segments.
