    Abstract: A data transmission method and a data transmission device are disclosed. The method comprises: sending, by a transmitting end, a channel request frame to a first receiving end on at least two sub-channels; parsing, by a receiving end after receiving a channel response frame from the first receiving end, the channel response frame to obtain second channel indication information; determining that the sub-channel on which the channel response frame is transmitted is idle; and sending data to the first receiving end on the sub-channel that is determined to be idle.

    Abstract: An uplink multi-user multi-input multi-output establishment method includes broadcasting, by a network side device, an uplink data sending announcement; receiving buffer information sent by a terminal that needs to send data, where the buffer information includes at least a sending level and a data sending length of to-be-sent data; determining, according to the buffer information, scheduling information for establishing uplink multi-user multi-input multi-output; and sending, to a terminal that is allowed to send data and selected from the terminal that needs to send data, a clear to send frame that carries the scheduling information, so that the terminal that is allowed to send data sends the to-be-sent data according to the scheduling information. The embodiments of the present disclosure effectively implement uplink multi-user multi-input multi-output establishment, so that signaling interworking is reduced, resource overheads are reduced, and data sending efficiency is improved.

    Abstract: A method and system for providing utilization information for a basic service set (BSS) in a wireless local area network system, performed by an access point, including generating and transmitting a BSS load element including a capable STA count field, a plurality of frequency and/or spatial stream underutilization fields, and a plurality of delta observable secondary channel utilization fields. The capable STA count field indicates a total number of STAs currently associated with the BSS. Each of the frequency and/or spatial stream underutilization fields indicates underutilized frequency and/or spatial stream domain resources on Orthogonal Frequency Division Multiple Access resource units for each channel, and each of the frequency and/or spatial stream underutilization fields is calculated based on RU size. Each of the delta observable secondary channel utilization fields indicates a utilization for a subband within a secondary channel calculated based on observable utilization on the corresponding secondary channel.

    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.

    Abstract: A bandwidth adjustment method includes: determining a bandwidth update value of a channel of a first network system and a bandwidth update value of a channel of a second network system and a bandwidth update value of a protective bandwidth according to a request of a user or a channel condition, so that updated bandwidths of the channels of the first network system and the second network system meet the request of the user or are adapted to requirements of channel conditions. By using the technical schemes, a network resource can be adjusted between multiple network systems when the multiple network systems share one network resource, thereby helping improve the application efficiency of a bandwidth resource and ensuring anti-interference capabilities of the network systems.

    Abstract: A method includes: sending an indication frame to an access point AP, where the indication frame includes first indication information and second indication information, the first indication information is used to indicate that a type of the indication frame is a PS-POLL frame, and the second indication information is used to indicate duration of the indication frame; and sending a data frame to the AP within the duration indicated by the second indication information. An STA sends PS-POLL to an AP by using an indication frame and reserves channel duration, so that the STA does not need to contend for a channel again when the STA sends an uplink data frame to the AP after receiving a downlink data frame sent by the AP, which allows the STA to receive downlink data and send uplink data within one TXOPA.
