Abstract
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.
Claims20
A method for data transmission, comprising:
- receiving, by a terminal device, indication information from a network device, the indication information indicating a first downlink scheduling time-domain resource in a first time-frequency resource region, the first time-frequency resource region corresponding to a scheduling unit in time-domain, and a frequency-domain resource in the first time-frequency resource region being a part of a system bandwidth, wherein the terminal device is configured by the network device to comprise a plurality of time-frequency resource regions comprising the first time-frequency resource region, each of the plurality of time-frequency resource regions has a different subcarrier spacing, and each of the plurality of time-frequency resource regions corresponds to a different frequency band within a same time-domain resource;
- and
- receiving, by the terminal device, data from the network device on the first downlink scheduling time-domain resource according to the indication information;
- wherein the indication information is configured to indicate a starting symbol and time-domain length of the first downlink scheduling time-domain resource.
