Abstract: Methods and apparatus are described for millimeter wave (mmWave) link beam failure recovery. A wireless multi-link device (MLD), such as a non-AP MLD, establishes mmWave link and a non-mmWave link with a second wireless MLD. Upon detecting a beam failure of the mmWave link, the wireless MLD transmits, via the non-mmWave link, an indication of the beam failure which may also include a request frame for a candidate beam training procedure to be initiated by the second wireless MLD. In response, the wireless MLD receives, via the mmWave link, candidate beam training packets from the second wireless MLD. The wireless MLD further transmits, via the non-mmWave link, beam training feedback information regarding the candidate beam training packets. In an example, a new Tx beam (e.g., a Tx beam with a highest received signal strength) is selected for maintaining the mmWave link.
