Communication method and base stations are provided. One example includes determining, by a base station, that co-channel interference exists. For N consecutive symbols before a guard period (GP) in a special subframe in a radio frame, the base station sends a signal by using M1 middle resource blocks (RBs) of the N symbols, and reserves use of an RB other than the M1 RBs in the N symbols, where both N and M1 are positive integers.
