摘要

Disclosed are a data transmission method and apparatus, which can improve the performance of a system. The method comprises: a terminal device receiving indication information sent by a network device, the indication information being used to indicate a first downlink scheduling time domain resource in a first time-frequency resource region, wherein frequency domain resources comprised in the first time-frequency resource region are a part of a system bandwidth; and the terminal device receiving, on a first downlink data time domain resource, data sent by the network device according to the indication information.

說明書

Optionally, if the network device configures multiple time-frequency resource regions including the first time-frequency resource region for a terminal device, the multiple time-frequency resource regions having different subcarrier spacings, the indication information includes information about a third downlink scheduling time-domain resource in a third time-frequency resource region. The third time-frequency resource region is the time-frequency resource region with a minimum subcarrier spacing in the multiple time-frequency resource regions. Correspondingly, the processor 810 is specifically configured to determine an ending moment of the third downlink data time-domain resource according to the indication information and determine a moment corresponding to the ending symbol of the first downlink data time-domain resource as the ending moment of the third downlink data time-domain resource.

In an optional example, those skilled in the art may know that the device 800 may specifically be the terminal device in the abovementioned embodiments and the device 800 may be configured to execute each flow and/or step corresponding to the terminal device in the abovementioned method embodiments, which will not be elaborated herein for avoiding repetitions.

FIG. 15 illustrates a data transmission device 900 according to another embodiment of the disclosure, which includes a processor 910 and a memory 920. Herein, the memory 920 is configured to store an instruction, and the processor 910 is configured to execute the instruction stored in the memory 920. Herein, executing the instruction enables the processor 910 to execute the following operations:
