Abstract:
The present invention discloses a link adaptation method, a base station and a terminal in a LTE system, wherein the method comprises: a terminal respectively calculating differences between a measured reference signal received power (RSRP) of a home service cell and the RSRPs of multiple adjacent cells; the terminal reporting the maximum difference in the differences to a base station; and the base station determining a modulation and coding scheme (MCS) for the terminal according to the maximum difference. The present invention does not introduce new overhead of the system, simplifies the flow of the AMC, and therefore improves the frequency spectrum efficiency of the system.
