Say, when it received a UE's signal from a specific beam, amplified the signal and sent it to the Gateway, how does the Satellite know which beam should be used?
Afterwards, if the Satellite received a signal from Gateway to specific UE, how does it know which beam to be used to send the signal back to the UE? after all, the bent-pipe Satellite doesn't maintain UE's RNTI, right?
Thanks.
