1. A non-access point (AP) multi-link device (MLD) associated with a wireless network, the non-AP MLD comprising:
a first non-AP station (STA) affiliated with the non-AP MLD, the first non-AP STA setting up a first link with a first AP affiliated with an AP MLD, wherein the first non-AP STA is a member of a restricted target wake time (R-TWT) schedule on the first link;
a second non-AP STA affiliated with the non-AP MLD, the second non-AP STA setting up a second link with a second AP affiliated with the AP MLD, where frame exchange takes place on the second link; and
a processor coupled to the first non-AP STA and the second non-AP STA, the processor configured to:
operate with the AP MLD in a non-simultaneous transmit and receive (NSTR) mode on the first link and the second link, and
coordinate with the AP MLD such that the frame exchange on the second link is terminated before a R-TWT service period (SP) starts on the first link.
