In such case, the terminal device may determine the first downlink scheduling time-domain resource according to the information, in the indication information, about the control channel resource. For example, the terminal device may determine the starting symbol of the first downlink data time-domain resource according to the time-domain length, in the indication information, of the control channel resource and determine the first downlink scheduling time-domain resource according to the starting symbol of the first downlink data time-domain resource. Specifically, the terminal device may determine an ending symbol of the control channel resource according to the time-domain length of the control channel resource and determine the starting symbol of the first downlink data time-domain resource to be an Nth symbol after the ending symbol of the control channel resource. N may be an integer more than or equal to 1, and a specific numerical value of N may be defined or preconfigured in a protocol. The embodiment of the disclosure is not limited thereto.
