5.2 Common communication mode
Original description:
A common communication mode in each frequency band shall be supported.
Agreed description on common mode:
Common mode (e.g., for discovery and communication) shall be supported for interoperability. Common mode used in different frequency bands needs not necessarily be the same.

5. 9.4.2.1. Simulation parameters for discovery
<month year>
doc.: IEEE <doc#>
 Simulation parameters for discovery
Agreed description:
PHY interface abstraction
- Common PHY mode:
The received Es/N0 can be used in the PER(Packet Error Rate) curves provided in DCN to know the value of PER of discovery signal sent by BPSK and 1/2 coding rate. Such PER curves were obtained assuming using convolution code and a packet length of 150 bytes at AWGN channel. Assuming bit errors in a packet are independent and uniformly distributed, the PER curves for a packet length of 16 bytes are obtained as
                        PER' = 1-(1-PER)(16/150)
. Optionally and in addition, proposers may provide results with their own PHY interface abstraction.

6. 9.4.3.1. Simulation parameters for communication
<month year>
doc.: IEEE <doc#>
 Simulation parameters for communication
Agreed description:
Traffic
Full buffer (for high data rate)
- latency is not measured at this parameter.
Poisson (for low and mid date rate)
- Inter arrival time : mean 10 msec
PHY interface abstraction
Perfect rate adaptation with target PER 0.1
- Common PHY mode :
The received Es/N0 can be used in the PER(Packet Error Rate) curves provided in DCN to know the value of PER of different coding and modulation schemes. Such PER curves were obtained assuming using convolution code and a packet length of 150 bytes at AWGN channel. Assuming bit errors in a packet are independent and uniformly distributed, the PER curves for a packet length of M bytes are obtained as
- Optionally and in addition, proposers may provide results with their own PHY interface abstraction.
Packet (MPDU) length
for Poisson model
- 64 bytes (for low data rate)
- 512 bytes (for mid data rate)

7. 9.4.3.2. Simulation scenario for communication
<month year>
doc.: IEEE <doc#>
 Simulation scenario for communication
Agreed description:
Two step uniform random drop model is assumed as following way: - a) A PD transmitter is dropped in the area of 500×500 m2 with uniform distribution. - b) A certain number of PD receivers are dropped with uniform random distribution within a distance d<100 m from the PD transmitter. A unicast scenario is mandatory, and additional scenarios such as multicast, group-cast or multi-hop are up to proposers. - c) The process described in a) and b) is repeated until a total number of PD transmitters reaches to Nt.

9. Clarification needed for the following
<month year>
doc.: IEEE <doc#>
Clarification needed for the following
Shadowing may be included (added) in a path loss model (to count for effects of surroundings),
only when such path loss model is a simplification, like the formula given by Prof. Lee. The path
loss models in the channel model document do not require shadowing, except for the UWB band.
In other words, if you do not find shadowing in clause is because shadowing is not required to be added.

10. Conclusion Remarks Remained issues related to TGD were discussed.
Resolved most of the issues.
Final approval is required at the face-to-face meeting.
Re-scheduling of the start of formal proposal needs to be discussed at the face-to-face meeting.
