The data rate is a 1602 function of the uplink data rate and the RX1DROffset as given by the following table. The 1603 allowed values for RX1DROffset are in the [0:5] range. Values in the [6:7] range are reserved 1604 for future use. 1605 1606 RX1DROffset 0 1 2 3 4 5 Upstream data rate Downstream data rate in RX1 slot DR0 DR0 DR0 DR0 DR0 DR0 DR0 DR1 DR1 DR0 DR0 DR0 DR0 DR0 DR2 DR2 DR1 DR0 DR0 DR0 DR0 DR3 DR3 DR2 DR1 DR0 DR0 DR0 DR4 DR4 DR3 DR2 DR1 DR0 DR0 DR5 DR5 DR4 DR3 DR2 DR1 DR0 DR6 DR6 DR5 DR4 DR3 DR2 DR1 DR7 DR7 DR6 DR5 DR4 DR3 DR2 Table 83: RU864-870 downlink RX1 data rate mapping 1607 1608 The RX2 receive window uses a fixed frequency and data rate.
