According to the 3GPP release 18, the maximum UE transmit power within the channel bandwidth of a 5G-NR carrier cannot be higher than 23 dBm, which is almost equivalent to 0:2 Watts [5].
The effect of the transmission of a large number of UEs on satellites under IAB operation will be the topic of a future research.
In this work we assume that P12 is equivalent to the total transmit power At Equation present.
By applying the formula in (6), the minimum number of LEO satellites to maintain an ISL connection was found to be 6 for orbital planes with an altitude of 1200 Km, and 8 for orbital planes with an altitude of 600 Km.
During the second time instant of the TDD scenario where S2 is in transmission mode, it is assumed that S1 deploys all of its available transmission power to serve the UE.
