A wireless transmit/receive unit (WTRU) may receive a first physical downlink shared channel (PDSCH) signal including a system information block (SIB) with a first time division duplex (TDD) uplink (UL)/downlink (DL) configuration. Also, the WTRU may receive a second PDSCH signal including dedicated radio resource control (RRC) signaling with a second TDD UL/DL configuration; and may receive a physical downlink control channel (PDCCH) signal including an uplink grant indicating at least one repetition transmission on a physical uplink shared channel (PUSCH). Further the WTRU may determine at least one time interval of the at least one repetition transmission would overlap with a downlink time interval indicated by the first TDD UL/DL configuration, the second TDD UL/DL configuration, or both. Also, the WTRU may transmit at least one repetition transmission on the PUSCH in at least one time interval that is non-overlapping with the indicated downlink time interval.
