Title:
INFORMATION TRANSMISSION METHOD, NETWORK DEVICE, AND TERMINAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/126964
Kind Code:
A1
Abstract:
Provided by the embodiments of the present application are an information transmission method, network device and terminal device, the method enabling the terminal device to recognize downlink transmission of the network device. The method is applied to a communication system comprising a network device and a terminal device, and frequency domain resources on a carrier used by the communication system are frequency domain resources used on the basis of a competition mechanism, the method comprising: the network device determining a first time-frequency resource that may be used, the first time-frequency resource being a time-frequency resource in a first downlink transmission opportunity; the network device sending first information to the terminal device by means of the first time-frequency resource, the first information being used for the terminal device to determine that the first time-frequency resource is a downlink time-frequency resource, and the first information being also used to determine an end position of the first downlink transmission opportunity, the first information being information obtained after carrying out first beam forming processing.
