Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 5:
6. A terminal device, wherein the terminal device is configured to operate in a communication system in a New Radio (NR) technology, and to communicate with a network device 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 terminal device comprising:
an input interface, an output interface, a processor and a memory for storing instructions executable by the processor;
wherein the input interface, output interface, the processor and the memory are connected through a bus system;
wherein the processor is configured to:
control the input interface to receive 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);
determine, 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
measure 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).
