WIRELESS LINK RECOVERY

Abstract: a wireless communications method includes acquiring, by a first radio terminal, one or more radio link qualities according to one or more first reference signal (rs) resources. one or more first rs resources are transmitted by a second radio terminal, in a first cell. the method includes determining, by the first radio terminal, a beam failure instance according to the one or more radio link qualities. the method further includes initializing, by the first radio terminal, a recovery request procedure. the recovery request procedure includes at least transmitting, in a case wherein a first condition is met, from the first radio terminal to the second radio terminal in a second cell, a link recovery request message. the first condition includes at least that a number of beam failure instances is equal to or greater than a first threshold value.
