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.

Abstract: A resource indication method, a device, and a system relate to the field of communications technologies. The method includes: allocating, by a base station, a BP to a terminal device, and sending, to the terminal device, a first message indicating a resource position of the BP; and receiving, by the terminal device, the first message sent by the base station, and then determining the resource position of the BP based on resource position information of at least one sub-BP, where the BP includes the at least one sub-BP, the BP is not greater than a maximum bandwidth supported by the terminal device, and the first message includes the resource position information of the at least one sub-BP. The BP is allocated by using a sub-BP as a granularity, so that signaling overheads can be reduced while a requirement for more flexible resource allocation is satisfied.
