1. A wireless transmit-receive unit (WTRU), comprising:
a processor configured to:
receive a downlink control information (DCI) associated with uplink scheduling information, wherein the DCI comprises spatial domain information and indicates a number of repetitions;
determine a sequence of sounding reference signal resource indicators (SRIs), wherein the determination of the sequence of SRIs is based on the spatial domain information and the number of repetitions;
determine, based on the sequence of SRIs, a first spatial relation for a first physical uplink shared channel (PUSCH) repetition transmission and a second spatial relation for a second PUSCH repetition transmission; and
send the first PUSCH repetition transmission using the first spatial relation and the second PUSCH repetition transmission using the second spatial relation.
