Title:
DATA TRANSMISSION METHOD AND DEVICE FOR FLEXIBLE DUPLEX SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/029464
Kind Code:
A1
Abstract:
Provided in the present application are a data transmission method and device for a flexible duplex system. By acquiring interference measurement information and a correspondence relationship between the interference measurement information and transmission resource information which transmits control information and data information, a terminal device carries out, on a time domain resource, a frequency domain resource or a spatial domain resource used for interference measurement, an interference measurement according to the interference measurement information; the terminal determines, according to the described correspondence relationship, transmission resource information for transmitting control information and transmitting data information, the transmission resource information being corresponding to the interference measurement; and the terminal device transmits or receives data according to the transmission resource information corresponding to the interference measurement. By predefining the correspondence relationship between the interference measurement information and the transmission resource information which is used for transmitting control information or data information, the terminal device is enabled to predict a transmission resource transmitting control information or data information and to detect data only on the predicted transmission resource, thus reducing the overhead of blind detections.
