4. General description
4.1a Pairnet
Change 4.1a as indicated:
A pairnet consists of at most two DEVs, as shown in Figure 4-0a. Typical communication distance is 10 cm or less for a pairnet DEV (PRDEV) with a high rate close proximity (HRCP) PHY. For a PRDEV with a THz PHY, typical communication distance is from a few centimeters up to several hundred meters. A PRDEV always connects as a pairnet.
4.2 Components of an IEEE 802.15.3 piconet
Change the fourth paragraph of 4.2 as indicated:
For HRCP PHYs and THz PHYs, the IEEE 802.15.3 piconet is not used.
4.5a Characteristics of HRCP PHY
4.5a.2 Pairnet using HRCP PHY
Insert new subclauses as 4.5b, 4.5b.1, and 4.5b.2, after 4.5a.2, as follows:
4.5b Characteristics of THz PHY
4.5b.1 THz PHY characteristics
Ibe TILi PHI. as described in Clause 13. is designed as an extension for wireless switched pomt-to-pomt applications. operating at a nominal PHI data rate of 100 0hs with falibacts to lower data rates as needed. The frequency band is from 252 01-li to 323 Gilt The THe P111 supports a range of channel handwsdtlis fissn 2 (1Hz to 70(1Hz.
The lóllowing two PHI modes ae defined for the THz Pill:
11 Li single earner mode lilY (lllz’S(’ I’I II).as dcscnhcd in 13.2
rh on-off keying mode P111 (11-Iz-OOK Nfl’). as described in 13.3
For DEVa that implement the fl-li PHI. at least one of the PHI modes is required
The THz-SC PHI as designed for extremely high PHI-SAP pnload data rates up to 100 Gha. depending on the combination of moihalahon. bandwidth, and codinir uscif The THz-SC P111 supports a wide range of modulations *2 BPSK. *2 QPSK. 52 8-PSK, *2 g-APSK. 16-QAM. and 64-QA?sI The FEC consists of two low-densit pants-check (LDPC) codes with rates of 1415 and 1115
The 11-lz-OOK PHI as designed for enat effective DEVa that require low complexity and simple design.
The Thz-O0K PITY supports a single modulation scheme. 00K. and three FEC schemes. The Reed Solomon IRS) code n mandatory and aLlows simple decoding without soil dccii ion information. The LDPC codes with rates of 1415 and 11:15 me optional and allow the use of soft-decision information.
4.5b.2 Pairnet using THz PHY
When a PRC-eapable [WV starts a panned, the type of paund it starts depends on the supported PHI modes For example. if the P1W-capable DEV sttppoits only the ‘11-li-SC mode, it will staal a THz-SC palmed tn which the Macon frame is sent with the TIlz-SC mode DEVa that support only the 11-li-SC mode aac aide to find and connect to the pairnet in TI-li-SC mode. The same process is med for a P1W-capable DEV that supports only Tilz-OOK mode.
If a PRC-capable [WV supports more than one fl-Li P1-Il mode, then tI $ able to select the type of pairnet it stats It allow’s connection from each type of DEl by transmitting both the TI li-SC mode Beacon frame and the THz-(JOK mode Beacon frame Figure 4-3a is an example of transmitting dual mode Beacon fraanes The number and duration of the access slots and the aupcrli’ame duration for each PIll mode are indicated by the Beacon frame with the csirttsponding PHI naode
The switched point-to-point nature of the connection nacans that Use paimet connection can be terntusated and a new pairnet connection can be set up with a different destination device The process of switching and the deterntosation of Use direction to the new access point as out of the scope of this standard.IEEE 802.15.3D pdf download.
