1. A method for use in a wireless transmit/receive unit (WTRU), the method comprising:
receiving, from a satellite base station (BS), first downlink control information (DCI) indicating that one or more first redundancy versions (RVs) from a plurality of first RVs are configured for a first transport block (TB), wherein the plurality of first RVs are associated with the first TB;
receiving, from the satellite BS, the first TB;
receiving, from the satellite BS, second DCI indicating that one or more second RVs from a plurality of second RVs and at least one cross redundancy version (cRV) are configured for a second TB, wherein the plurality of second RVs are associated with the second TB and the at least one cRV is associated with a plurality of bits from both the first TB and the second TB;
receiving, from the satellite BS, the second TB; and
on a condition that the WTRU does not successfully decode at least one of the first TB based on the one or more first RVs or the second TB based on the one or more second RVs, decoding the first TB and second TB jointly based on the at least one cRV.
