  • Publication number: 20220377766
    Abstract: A method for enabling Configured Uplink with repetition in a wireless communications system. In examples discussed herein, a wireless device (e.g., a user equipment) receives a configured number of repetitions from a base station (e.g., an eNB). Accordingly, the wireless device repeats a Transport Block (TB) corresponding to a Physical Uplink Shared Channel (PUSCH) transmission across an equal number of consecutive PUSCHs as the configured number of repetitions. As a result, the wireless device can support Configured Uplink with repletion, for example, when the repetition is configured for New Radio Unlicensed band (NR-U) Configured Uplink.
