Abstract: A data transmission indication method and apparatuses carrying out the method are described herein. The method includes sending, by an access point, orthogonal frequency division multiple access (OFDMA) physical layer signaling to a terminal. The OFDMA physical layer signaling indicates, to the terminal, a subchannel allocated for the terminal, so that the terminal determines the subchannel according to the OFDMA physical layer signaling. The OFDMA physical layer signaling includes an identifier of the terminal and subchannel information corresponding to the identifier of the terminal. A manner in which the access point allocates a subchannel for each terminal according to OFDMA physical layer signaling enables the access point to indicate subchannels for more terminals.

Abstract: Example methods and apparatus for indicating downlink service data are described. One example method includes sending, by a first station (STA), a request frame to a wireless access point (AP). The request frame includes listen interval information, the listen interval information includes duration of a first listen interval, and the first STA is equipped with main radio and a wake-up receiver. The first STA receives a response frame sent by the AP, where the response frame carries an identity allocated by the AP to the first STA, and the identity of the first STA comprises an identity of the wake-up receiver of the first STA. The first STA controls the wake-up receiver to wake up within the first listen interval, and receives a wake-up beacon frame periodically sent by the AP.

Abstract: Disclosed is a data transmission method. The method comprises: reserving a first channel and a second channel, where the first channel is used for transmitting data and the second channel is used for transmitting ACKs; sending data to a receiving end on the first channel that is reserved; receiving an ACK that is sent by the receiving end and corresponds to the data on the second channel that is reserved and determining whether the data needs to be cached based on information carried in the ACK; and if the information carried in the ACK indicates that the receiving end has correctly received the data, clearing the data that is cached by a sending end. Through separate transmission of the data and the ACK, an efficiency problem of the sending end in providing MAC in a wireless system in a condition of a limited cache capacity is resolved.
