The end-device therefore opens receive slots starting at: 1880 1881 First slot BEACON_RESERVED + PingOffset × SlotLen Slot 2 BEACON_RESERVED + (PingOffset + PingPeriod) × SlotLen Slot 3 BEACON_RESERVED + (PingOffset + 2 × PingPeriod) × SlotLen … … Table 60: Receive-slot starting times 1882 1883 1884 If the end-device simultaneously serves a unicast and one or more multicast slots, this 1885 computation SHALL be performed multiple times at the beginning of a new beacon period: 1886 once for the unicast address (end-device network address) and once for each multicast group 1887 address. 1888 If a Class A RX1 or RX2 receive slot collides with a Class B multicast or unicast slot, the end- 1889 device SHALL listen to the Class A RX slot that has priority. 1890 1891 Note: As defined in the Class A section, the end-device does not open 1892 the RX2 receive window if a valid unicast downlink addressed to the 1893 end-device is received in the RX1 receive window. 1894 1895 The randomization scheme prevents a systematic collision between unicast and multicast 1896 slots. If a collision occurs during a beacon period, one is unlikely to occur again during the 1897 next beacon period. 1898
