Regional Parameters RP002-1.0.5 ©2022-2025 LoRa Alliance ® Page 86 of 116 The authors reserve the right to change specifications without notice. When the device transmits in a channel whose frequency is <922 MHz, the transmit power 1760 SHALL be limited to +10 dBm EIRP even if the current transmit power level set by the Network 1761 Server is higher. 1762 3.11.4 KR920-923 Join-Accept CFList 1763 The KR920-923 band LoRaWAN implements an OPTIONAL CFList of 16 octets in the Join- 1764 Accept message for both CFListType equal to 0 and CFListType equal to 1. When 1765 receiving a CFListType equal to 1, it SHALL be interpreted according to the channel list 1766 definition in Section 3.3.1.2 (900 MHz Fixed Channel List Definition). 1767 3.11.5 KR920-923 LinkADRReq Command 1768 The KR920-923 channel plan of LoRaWAN supports a minimum of 24 and a maximum of 80 1769 channels. The ChMaskCntl field of the LinkADRReq command has the following meaning: 1770 ChMaskCntl ChMask Applies To 0 Channels 0 to 15 1 Channels 16 to 31 2 Channels 32 to 47 3 Channels 48 to 63 4 Channels 64 to 79 5 10 LSBs control channel blocks 0 to 9, 6 MSBs are RFU 6 All channels ON: The device SHALL enable all currently defined channels independently of the ChMask field value. 7 RFU Table 84: KR920-923 ChMaskCntl value 1771 If ChMaskCntl = 5, the corresponding bits in the ChMask enable and disable a bank of eight 1772 channels defined by the following calculation: [ChannelMaskBit * 8, ChannelMaskBit * 8 1773 +7]. 1774 If the ChMaskCntl field value is RFU, the end-device SHALL 4 reject the command and unset 1775 the Channel mask ACK bit in its response. 1776 3.11.6 KR920-923 Maximum Payload Size 1777 The maximum MACPayload size length (M) is given by the following table for the regulation 1778 of dwell time; less than 4 seconds with LBT. It is derived from a limitation of the PHY layer, 1779 depending on the effective modulation rate used, taking into account a possible repeater 1780 encapsulation layer. The maximum application payload length in the absence of the 1781 OPTIONAL FOpts control field (N) is also given for information only. The value of N might be 1782 smaller if the FOpts field is not empty. 1783 Data Rate M N 0 59 51 1 59 51 2 59 51 3 123 115 4 230 222 5 230 222 12 230 222 13 230 222 6:11 and 14:15 Not defined Table 85: KR920-923 maximum payload size (repeater compatible) 1784 1785
