  • Publication number: 20260181629
    Abstract: According to some embodiments, a method is performed by a reduced capability (RedCap) wireless device. The method comprises: receiving a physical downlink shared channel (PDSCH), the PDSCH including scheduling for an uplink transmission; determining whether a time duration between receiving the PDSCH and a start of the scheduled uplink transmission is greater than a threshold; and upon determining that the time duration between receiving the PDSCH and the start of the scheduled uplink transmission is greater than the threshold, transmitting the scheduled uplink transmission. The threshold depends on whether the PDSCH is received in a bandwidth that is larger than a reduced bandwidth associated with RedCap wireless devices.
