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, the first downlink scheduling time-domain resource is different from a second downlink scheduling time-domain resource in a second time-frequency resource region, and the first time-frequency resource region and the second time-frequency resource region correspond to a same time-domain resource and correspond to different frequency-domain resources respectively.

Optionally, that the first downlink scheduling time-domain resource is different from the second downlink scheduling time-domain resource in the second time-frequency resource region includes that:

    • the starting symbol of the first downlink scheduling time-domain resource is different from a starting symbol of the second downlink scheduling time-domain resource; and/or
    • the time-domain length of the first downlink scheduling time-domain resource is different from a time-domain length of the second downlink scheduling time-domain resource.

Optionally, a starting symbol of the first downlink data time-domain resource is immediately next to an ending symbol of a control channel resource in the first time-frequency resource region; or

    • the stalling symbol of the first downlink data time-domain resource is a spaced from the ending symbol of the control channel resource in the first time-frequency resource region by at least one symbol.
