Correct. > T_sched + slot_offset is the beggining of 2nd slot > T_sched + 2*slot_offset is the beggining of 3rd slot and so on... Every payload slot has it's own, theoretically freely configurable slot offset. So there is slot_offset_1, slot_offset_2, ... They do not need to be multiples of some base slot or so. > All transmissions must begin after beggining of slot and end before > next slot starts. Right. Jan
