Abstract: Provided in the embodiments of the present application are a wireless communication method and device. For NSTR characteristics of a mobile AP MLD, it is designed that uplink simultaneous transmission between a plurality of independent non-access-point devices is triggered in a mobile AP MLD scenario. By means of the embodiments of the present application, an uplink access restriction is relaxed, and under the condition of not affecting the transmission quality of a single-link device on a main link, the success rate of uplink simultaneous transmission between mobile AP MLDs is increased, and a transmission service having a high throughput is also provided.

Abstract: A joint transmission method, a terminal device, a target network device, and a cooperative network device. The method comprises: a terminal device sends a first data frame to a target network device and at least one cooperative network device, wherein the cooperative network device is used for joint transmission of the first data frame; the terminal device determines, according to feedback of the target network device and/or feedback of the cooperative network device, whether to retransmit the first data frame.
