1. An information transmission method, the method being applied to a communication system in a New Radio (NR) technology, the communication system comprising a network device and a terminal device, communicating through a frequency-domain resource on a carrier used by the communication system, the frequency-domain resource being a contention based frequency-domain resource, the method comprising:
receiving, by the terminal device, first information from the network device through a first time-frequency resource, wherein the first time-frequency resource is a time-frequency resource in a first downlink transmission burst, the first information is transmitted on the first time-frequency resource through a physical downlink control channel (PDCCH), and the first information comprises Downlink Control Information (DCI);
determining, by the terminal device according to the first information, that the first time-frequency resource is a downlink time-frequency resource, wherein the first information is further used to determine an ending position of the first downlink transmission burst, and the first information is obtained by first beamforming; and
measuring, by the terminal device, channel state information (CSI) of a downlink channel from the network device according to the ending position of the first downlink transmission burst and a channel state information-reference signal (CSI-RS).
