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 scheduling unit may specifically a self-contained scheduling unit. In such case, the network device may transmit a common control signal, and the common control signal may contain information about the first uplink scheduling time-domain resource. Or, the common control signal may contain information about an uplink and downlink switching time period in the first scheduling unit. In such case, the terminal device may determine the first uplink scheduling time-domain resource according to the information about the uplink and downlink switching time period. For example, the terminal device may determine an ending symbol of the uplink and downlink switching time period according to the information about the uplink and downlink switching time period, determine the starting symbol of the first uplink scheduling time-domain resource to be a first symbol immediately next to the ending symbol of the uplink and downlink switching time period and determine the first uplink scheduling time-domain resource according to the determined starting symbol. However, the embodiment of the disclosure is not limited thereto.
