Abstract: Embodiments of the disclosure provide a method, an apparatus, and a device for controlling wireless transmission. A first access point in a first system selects, from access point devices in a second system, one access point as a second access point to which the first access point is attached, and connects to the second access point to send first information to a network device. In so doing, the network device determines, according to the first information and second information that is sent by a user device via an access point to which the user device is attached, a transmission mode and a transmission bandwidth between the first access point and the user device, thereby solving a problem of cross timeslot interference that occurs when wireless local area network systems of different types have an overlapping coverage area and are not synchronized.

Abstract: Disclosed are methods and devices for data transmission in a wireless local area network. According to the embodiments of the present application, through transmitting by a terminal a first data frame to an access device, where the first data frame includes indication information and uplink data and the indication information is used to indicate a power save poll and uplink data transmission, the terminal can receive a second data frame which is transmitted by the access device according to the first data frame, where the second data frame includes response information of the power save poll indicated by the indication information. Since the first data frame carrying the uplink data indicates the power save poll simultaneously, downlink data from the access device can be inquired or requested at the same time of transmitting the uplink data, so that data transmission efficiency is improved.

Abstract: A multicast packet transmission method and an apparatus are provided that relate to the communications field and define how multicast data is sent to stations (STAs) by using a multicast association identifier (AID). The method includes: allocating, by an access point (AP), a corresponding multicast AID to STAs, where the multicast AID is set in a short media access control (MAC) header of a multicast packet; and sending, by the AP, the multicast packet to at least two STAs, so that the at least two STAs determine, according to the multicast AID, whether the multicast packet is a multicast packet corresponding to the at least two STAs, where the at least two STAs are in a same multicast group.

Abstract: Embodiments of this application provide a control information sending method and apparatus, where the method includes: obtaining a control information indication message from a first standard network, selecting a second standard network from one or more other networks that constitute a heterogeneous network with the first standard network, and sending the control information indication message to the second standard network, and then to a client over the second standard network. The control information indication message is used to instruct to substitutively send control information of the first standard network. According to the method and apparatus provided, the control information of the first standard network is substitutively sent over the second standard network, and sending the control information does not need to occupy bandwidth of the first standard network. Therefore, in comparison with the prior art, a network capacity of service data sent over the first standard network can be increased.
