The present application discloses a communications method and apparatus. The method includes: determining a radio frame, where the radio frame includes a period, the period includes at least one first sub-period and at least one second sub-period, the first sub-period corresponds to a first procedure, and the second sub-period corresponds to a second procedure; the first sub-period includes n first time slices, different beams are used in adjacent first time slices in the n first time slices, there is a first guard interval between the adjacent first time slices, and the second sub-period includes m second time slices; and at least one first time slice is adjacent to at least one second time slice and there is no guard interval between the at least one first time slice and the at least one second time slice that are adjacent to each other; and performing communication by using the radio frame.
