  • Publication number: 20200281001
    Abstract: The present disclosure provides a data transmission method, a network device and a terminal. In embodiments of the present disclosure, the network device determines a processing interval of the terminal according to parameter(s) reported by the terminal, and then compares a scheduling interval for resource allocation for the terminal with the determined processing interval of the terminal. When the scheduling interval is less than the processing interval, the network device transmits data through a physical downlink shared channel after the scheduling interval by using pre-configured quasi-co-location information corresponding to the terminal.
