  • Publication number: 20240040646
    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.
