    Abstract: Embodiments of the present invention relate to the communications field, and provide a multicast sending apparatus, a multicast receiving apparatus, and a multicast transmission determining method. The method includes: sending at least one multicast frame to multiple stations in a multicast manner; generating a multicast indication request frame, where the multicast request indication frame includes an identifier of the at least one multicast frame, the multicast indication request frame is used to instruct the multiple stations to send an indication frame within a specified timeslot in a unicast and contention-based manner, and the indication frame includes an identifier of a to-be-retransmitted multicast frame; and sending the multicast indication request frame to the multiple stations in a multicast manner.

    Abstract: A data transmission method and apparatus are provided, which can improve a throughput rate of a system, and improve data transmission performance and user experience. The method comprises determining a target bit sequence. In the system state, a peak-to-average power ratio PAPR corresponding to the target bit sequence is less than a PAPR that corresponds to a bit sequence corresponding to the data length of the target data. The method comprises adding the target bit sequence to length bits that are in a legacy signal field of a target preamble, and performing transmit power enhancement processing on a legacy short training field, a legacy long training field, and the legacy signal field that are in the target preamble according to the transmit power amplification limit.
