Abstract: Example embodiments of the present disclosure relate to beam failure recovery mechanism. According to embodiments of the present disclosure, there are provided an improved solution for reporting candidate beams in serving cells. If a beam failure occurs in a serving cell, the first device determines a candidate beam for beam failure recovery from a plurality of beams in the serving cell based on link qualities of the plurality of beams. The first device also determines a resource configuration for a random access for the beam failure recovery for the first device or a resource to be used for the random access, The first device further generates an indication for indicating a characteristic of the candidate beam or a characteristic of a beam for performing the random access, based on at least one of the determined resource configuration or the determined resource. The first device also transmits an identity of the candidate beam and the indication to a second device. The second device performs the beam failure recovery based on the candidate beam and the characteristic of the candidate beam.

Abstract: A technique of accounting for the difference in required output power reduction or required duty cycle when selecting the RO in addition to the DL RS. Both output power reduction and duty cycle are independently determined by UE itself (i.e., UE needs to be able to determine itself required power backoff and/or duty cycle in order to meet RF exposure requirements). Advantageously, a RACH procedure in which the UE determines both output power reduction and duty cycle independently enables better choices of output power reduction and duty cycle, enhancing data activity and coverage.
