Abstract
This invention discloses method and apparatus for obtaining channel state information, and relates to the field of communication techniques, capable of reducing signaling and feedback overheads and lowering UE operation complexity. According to the solutions provided in embodiments of this invention, a RS predetermined transmission time and a RS predetermined frequency are transmitted to a UE by any one cell of at least two cells; each cell or cell group out of the at least two cells, according to the RS predetermined transmission time and the RS predetermined frequency, transmits a RS to the UE on different RS resources; the measurement result transmitted by the UE is received, which comprises CSI between any one cell or cell group out of at least two cells and the UE. The solutions provided in embodiments of this invention are applicable when it is required to obtain CSI between multiple cells and a UE.
