Provided in embodiments of the present disclosure are a data transmission method, and a terminal. The method includes: when a terminal meets a first condition of using a first scheme to transmit data, using the first scheme to transmit data; when the terminal meets a second condition of using a second scheme to transmit data, using the second scheme to transmit data; or when the terminal meets the first condition of using the first scheme to transmit data and the second condition of using the second scheme to transmit data, using any one of the first scheme and the second scheme to transmit data, wherein the first scheme is a scheme without radio resource control (RRC) signaling, and the second scheme is one of direct data transmission schemes other than the first scheme. The embodiments of the present disclosure realize selection of a data transmission scheme in a process of transmitting small data.

A multi-link aggregation transmission method and a related apparatus. The method includes: a receive end receives at least one of a data frame and a BAR frame over a plurality of links between the receive end and a transmit end, where the plurality of links includes a first link. The receive end receives a block acknowledgment request BAR frame over the first link, where the BAR frame carries SSN_1 corresponding to the first link. The receive end adjusts, based on SSNs corresponding to all the links, a value of a current starting sequence number WinStart of a scoreboard window. The receive end processes, based on the adjusted WinStart, a data frame received over the plurality of links. The receive end can adaptively adjust the WinStart.

Systems and methods are provided for leveraging uplink (U)L scheduling information obtained by way of Quality of Service (QoS) Null/QoS Data frames and Media Access Control (MAC) headers transmitted by any station (STA). This UL scheduling information can be read by any access point (AP) in an extended service set (ESS), and used to improve network performance. For example, an AP may use such UL scheduling information (from STAs associated to co-channel APs in the same ESS) to minimize the latency for UL latency-sensitive traffic in that ESS. Additionally, an AP may use such UL scheduling information to minimize contention amongst STAs connected to different APs on the same channel in the same ESS, thereby improving system capacity.
