1. A method, comprising:
receiving, by a user equipment, at least one network entity failure indication configuration;
detecting, by the user equipment, that at least one first network entity satisfies at least one beam-failure condition, wherein the at least one network entity failure indication configuration comprises at least two sets of periodic physical uplink control channel resources configured for transmission of at least one indication of the at least one detected first network entity;
selecting, by the user equipment, at least one resource based on the at least one received network entity failure indication configuration, the at least one resource configuring transmission of the at least one indication that the detected at least one first network entity satisfies the at least one beam-failure condition; and
transmitting, by the user equipment, the at least one indication of the at least one first network entity that satisfies the at least one beam-failure condition, the at least one indication comprising a scheduling request corresponding to beam failure recovery of at least one beam-failure detection reference signal subset of the at least one detected first network entity,
wherein the transmitting the at least one indication is transmitted to at least one second network entity, and
wherein the at least one second network entity is in a non-failure condition, the at least one indication comprises at least one medium access control (MAC) control element (CE) transmitted via at least one physical uplink shared channel, and the at least one MAC CE indicates at least one network entity beam failure indication when physical uplink resources are unavailable.
