1. A first node for wireless communication, comprising:
a first receiver, receiving M1 first-type reference signals, measurements for the M1 first-type reference signals being used for generating first radio-link quality, M1 being a positive integer greater than 1; receiving M2 first-type reference signals, measurements for the M2 first-type reference signals being used for generating second radio-link quality, M2 being a positive integer greater than 1; and
a first transmitter, transmitting a first radio signal on a target radio resource;
wherein the first radio-link quality and the second radio-link quality correspond to a first threshold and a second threshold respectively, at least one of the first radio-link quality and the second radio-link quality is worse than its corresponding threshold, the first threshold and the second threshold both being real numbers, and the first threshold is the same as the second threshold; the first radio-link quality and the second radio-link quality are used for determining the target radio resource from a first radio resource, a second radio resource and a third radio resource, and for determining the first radio signal; the first radio resource and the second radio resource are allocated to a same type of physical-layer channel, and the first radio resource and the third radio resource are allocated to different types of physical-layer channels; the first radio resource and the second radio resource correspond to a first index and a second index respectively, the first index and the second index being two different non-negative integers; the first index is used for determining the M1 first-type reference signals, and the second index is used for determining the M2 first-type reference signals; the M1 first-type reference signals are used for a beam failure detection in a beam failure recovery mechanism, and the M2 first-type reference signals are used for a beam failure detection in a beam failure recovery mechanism; the M1 first-type reference signals comprise a periodic CSI-RS, and the M2 first-type reference signals comprise a periodic CSI-RS.
