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: The embodiments of the present disclosure provide a wireless communication method and device. When there is an overlapping region between LL TWT SPs on a plurality of links of an NSTR Non-AP MLD, leader/follower transmission modes on the multiple links are set, so as to solve the problem that a low-latency service on a certain link cannot be transmitted in an LL TWT SP as the NSTR Non-AP MLD cannot receive and transmit at the same time. Therefore, the transmission delay requirement of the low-latency service on the plurality of links of NSTR Non-AP MLD can be guaranteed, and the transmission on the plurality of links of the NSTR Non-AP MLD can be optimized.
