Abstract

An embodiment of this application provides a method for transmission in a time interval. The time interval includes one or more first time units and one or more second time units. The one or more first time units are used to transmit a first-type signal, and a quantity of first time units is associated with a quantity of first-type signals. The one or more second time units are used to transmit a second-type signal. In the method, a receiving node may obtain time unit information, where the time unit information is used to obtain a location of the one or more second time units, that is, determine a time domain location of the second-type time-frequency resource in the time interval. Then, the receiving node may receive or send the second-type signal on the second-type time-frequency resource.
