Abstract: A transmission control method includes generating, by a first device, transmission control information, and sending the transmission control information to the second device. The transmission control information includes resource indication information, compression indication, and first indication. The resource indication information indicates a transmission resource allocated by the first device to a second device. The transmission resource includes at least two symbols. The compression indication indicates a numerology of a specific symbol in the transmission resource. The specific symbol includes at least an end symbol or a second symbol. The end symbol is the last symbol in the transmission resource. The second symbol is a symbol in the transmission resource and is used for transmitting only a demodulation reference signal or a long training field. The second symbol includes at least one symbol. The first indication indicates a numerology of a symbol in the transmission resource other than the specific symbol.

Abstract: A method for sending a wake-up frame includes generating, by a sending device, a plurality of short wake-up frames, where each of the plurality of short wake-up frames includes an index and an address segment. The index is used to indicate a number of the address segment, the plurality of short wake-up frames include at least N short wake-up frames whose indexes are different from each other, N is a positive integer, and N≥2. The method further includes sending, by the wake-up device, the plurality of short wake-up frames so that a receiving device can determine, based on N address segments carried in any N short wake-up frames whose indexes are different from each other in the plurality of short wake-up frames, whether the receiving device is a target wake-up device of the sending device.
