If the end-device receives the Join- 1122 Accept message from one of the above downlink (DL) common join channels, the end-device 1123 SHALL use the corresponding channel plan 29 in the above table. 1124 2.9.2.1 Channel Plan for 20 MHz Antenna 1125 For 20 MHz antennas, the CN470-510 MHz band shall be divided into two channel plans: 1126 Type A and plan Type B. 1127 For channel plan Type A: 1128 • Upstream (Group 1) – 32 channels, numbered 0 to 31, utilizing LoRa 125 kHz BW, 1129 varying from DR0 to DR5, using coding rate 4/5, starting at 470.3 MHz and 1130 incrementing linearly by 200 kHz to 476.5 MHz 1131 • Downstream (Group 1) – 32 channels, numbered 0 to 31, utilizing LoRa 125 kHz BW, 1132 varying from DR0 to DR5, using coding rate 4/5, starting at 483.9 MHz and 1133 incrementing linearly by 200 kHz to 490.1 MHz 1134 • Downstream (Group 2) – 32 channels, numbered 32 to 63, utilizing LoRa 125 kHz BW, 1135 varying from DR0 to DR5, using coding rate 4/5, starting at 490.3 MHz and 1136 incrementing linearly by 200 kHz to 496.5 MHz 1137 • Upstream (Group 2) – 32 channels, numbered 32 to 63, utilizing LoRa 125 kHz BW, 1138 varying from DR0 to DR5, using coding rate 4/5, starting at 503.5 MHz and 1139 incrementing linearly by 200 kHz to 509.7 MHz 1140 1141 Figure 3: Channel plan type A for 20MHz antenna channel frequencies 1142 1143 For channel plan Type B: 1144 • Upstream (Group 1) – 32 channels, numbered 0 to 31, utilizing LoRa 125 kHz BW, 1145 varying from DR0 to DR5, using coding rate 4/5, starting at 476.9 MHz and 1146 incrementing linearly by 200 kHz to 483.1 MHz 1147 • Downstream (Group 1) – 32 channels, numbered 0 to 3,1 utilizing LoRa 125 kHz BW, 1148 varying from DR0 to DR5, using coding rate 4/5, starting at 476.9 MHz and 1149 incrementing linearly by 200 kHz to 483.1 MHz 1150 • Upstream (Group 2) – 32 channels, numbered 32 to 63, utilizing LoRa 125 kHz BW, 1151 varying from DR0 to DR5, using coding rate 4/5, starting at 496.9 MHz and 1152 29 The corresponding channel plan can be determined by the uplink join channel, which corresponds to a pair of common join channels including UL and DL. The DL join channel is the channel from which the end-device receives the join-accept message.
