METHOD AND DEVICE FOR MEASURING CHANNEL STATE INFORMATION

摘要

The present invention provides a method and a device for measuring channel state information. The method comprises: a first device receiving a first signal sent through a downlink channel by a second device, and receiving a second signal sent through an uplink channel by at least one third device; and the first device determining channel state information (CSI) according to the first signal and the second signal. By using the method, it can be achieved that a network device schedules an uplink resource and a downlink resource according to channel state information determined by a first device, so as to improve the utilization rate of the resources.
