Title:
DATA TRANSMISSION METHOD AND APPARATUS, AND RELATED DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/077412
Kind Code:
A1
Abstract:
Disclosed are a data transmission method and apparatus, and a related device. The method comprises: at a first time point, receiving first control information from a network device, wherein the first control information is used for indicating target data to be transmitted, a target time point for transmitting the target data, and a first beam for transmitting the target data; at a second time point later than the first time point, a second beam being able to be utilized to transmit other data with the network device; and when a time interval between the target time point and the first time point is greater than or equal to a larger value between a preset threshold value and a target interval, the first beam being able to be utilized to transmit the target data with the network device, with the target interval being the sum of a time interval between the first time point and the second time point and the duration required by beam switching. The possibility of a target data transmission failure caused by the unavailability of the first beam is reduced, and the reliability of target data transmission is improved.
