1. A wireless communications method, comprising:
receiving, by a first radio terminal, one or more first reference signal (RS) resources from a base station to acquire one or more radio link qualities according to the one or more first RS resources; and
transmitting, as part of a recovery request procedure, from the first radio terminal to the base station, a link recovery request message that includes an index of a first cell and an index of at least one RS resource from an RS resource group, in a case that a number of beam failure instances determined according to the one or more radio link qualities is equal to or greater than a first threshold value and a channel quality of the at least one RS resource selected from the RS resource group is higher than or equal to a second threshold value,
wherein the at least one RS resource is determined according to a new candidate beam identification.
