Abstract: The present invention discloses an access point, a station, and a beacon frame sending method and system, relates to the communications field, and resolves a problem of relatively large network overheads caused for purposes of ensuring that in a WLAN system having multiple channels, a STA can quickly access a network. A specific solution is as follows: A first sending unit sends a beacon indication frame on each subchannel of N subchannels, where the beacon indication frame is used to indicate configuration information of a beacon frame; and a second sending unit sends the beacon frame on at least one first subchannel. The present invention is applied to a beacon frame sending process.

Abstract: An embodiment method for error feedback includes receiving, by a wireless device, a first preamble field and a repeated preamble field of a first frame. The method also includes decoding, in a frequency domain, the first preamble field and the repeated preamble field to obtain a first set of bits and a second set of bits. The method also includes performing a bitwise comparison of the first set of bits and the second set of bits to determine at least one bit error position.

Abstract: The present disclosure relates to data transmission methods and communications devices. One example communications device includes a transceiver. The transceiver is configured to send a transmission frame to a second communications device, where the second communications device acquires data information in the transmission frame, and the transmission frame includes a first part and a second part. The transceiver is configured to send the first part of the transmission frame by using a first quantity of subcarriers. The transceiver is configured to send the second part of the transmission frame by using a second quantity of subcarriers, where the first quantity is not equal to the second quantity. The transceiver is further configured to perform a next time of information transmission with the second communications device.

Abstract: A power control method and apparatus are provided. The method includes: determining, by a first station obtaining a transmission opportunity (TXOP), status indication information after determining working statuses of M second stations during the TXOP, where the status indication information is used to instruct a second station in the M second stations that needs to receive data during the TXOP to remain in a listening state, and instruct a second station in the M second stations that does not need to receive data during the TXOP to enter a sleep state; and sending, by the first station, the status indication information.

Abstract: Embodiments of this application provide a service data transmission method, an access point, and a station. The method includes: receiving, by a station, a control frame, where the control frame includes control information; contending for a resource based on the control information; and sending first-type service data of the station to an access point on the resource obtained by contention, where the control information is used to instruct the station to contend for the resource used to transmit the first-type service data. In the embodiments of this application, the access point triggers the station to perform a procedure of reporting uplink first-type service data, and this can improve transmission efficiency of service data.
