The present application relates to the field of wireless communications. Disclosed are a channel state information (CSI) reference resource indication and measurement method and device, so as to reduce the complexity of measurement and computation performed by a terminal. In the solution provided by the embodiments of the present application, a network side informs a terminal of a periodic value and/or a subframe offset value of a periodic CSI reference resource, and after the periodic value and/or the subframe offset value of the periodic CSI reference resource on a carrier is determined, the terminal determines, through a frame structure type used by the carrier and according to the determined periodic value and/or subframe offset value of the periodic CSI reference resource, a time-frequency resource corresponding to the effective CSI reference resource and measures the CSI in the determined time-frequency resource. It can be seen from the above that, the solution can effectively reduce the complexity of measurement and computation performed by a terminal. |
