  • Methods And Apparatus For Synchronizing Critical Data Transmission
    Publication number: 20210377888
    Abstract: The present disclosure provides techniques for reducing latency of periodic URLLC transmission and other critical data transmission with low latency requirements. To support periodic URLLC traffic, SPS with repetition is used. Before synchronization is achieved, the base station sends to the UE an SPS configuration for a periodic uplink data transmission. When the starting time of the data transmission is not known, the base station over-provisions SPS resources for the periodic data transmission. Based on the timing of the data transmissions, the base station adjusts the timing of the SPS configuration.
