When the end-device is using the Adaptive Data Rate mode and transmits using the 828 DRcurrent uplink data rate, the following table defines the next uplink data rate (DRnext) 829 the end-device SHALL use during data rate back-off: 830 DRcurrent DRnext Comment 0 NA Already the default lowest data rate 1 0 2 1 3 2 4 3 5 0 6 5 7 3 8 7 Table 21: US902-928 uplink data rate back-off 831 Transmit power levels relative to the maximum conducted power level of the end-device are 832 indicated in the following TXPower table: 833 834 TXPower Configuration (Conducted Power) 0 30 dBm – 2*TXPower 1 28 dBm 2 26 dBm 3..13 …. 14 2 dBm 15 Defined in [TS001] 3 Table 22: US902-928 TXPower 835 3.5.4 US902-928 Join-Accept CFList 836 For LoRaWAN 1.0.1 and 1.0.2, the US902-928 region does not support the use of the 837 OPTIONAL CFList appended to the Join-Accept message. If the CFList is not empty, it SHALL 838 be ignored by the end-device. 839 The US902-928 LoRaWAN supports the use of the OPTIONAL CFList appended to the Join- 840 Accept message. If the CFList is not empty, the CFListType field SHALL contain the value 841 of one (0x01) to indicate the CFList contains a series of ChMask fields as defined in Section 842 3.3.1. Channel-ID values from 0 to 71 are supported and SHALL be interpreted as 843 the channel number to be enabled or disabled. A cleared bit in the CFList SHALL 844 disable the associated channel. All bits corresponding to Channel-ID values above 71 845 are RFU. 846 847
