he CSI-RS and SS Blocks can be configured to be used together. Beam failure recovery request (BFRQ) Once the beam(s) have been detected as failed, the gNB needs to know about the fail- ure SO that appropriate actions are taken, likely the scheduling of the control and data traffic on new beams. A beam recovery request can be transmitted if the number of consecutive detected beam failure instances exceeds a configured maximum number. The BFRQ is done by transmitting signals on the uplink, and one of the handy signals to use are the PRACH resources, which are available to the UE and which provide contention-free random access (CFRA) toward the gNB, as no collisions will occur for these resources. The UE receives a configuration for PRACH transmission, and these resources are associated with periodic CSI-RS or SS Blocks, which are used as Beam-Failure Reference Signal (BFRS). The association between the CSI-RS/SS Blocks and PRACH resources also implies that the detected DL beam will be used for UL transmission; hence, the concept of beam correspondence is applied. The BFRQ may also be transmitted in a contention-based manner (CBRA), a situation in which the UE is utilizing the contention-based RACH procedure where preamble resources are mapped to downlink signals. In case both CSI-RS and SS Blocks are configured for the UE, the PRACH preambles are associated with the SS Blocks only; in this case, the CSI-RS resources used for new beam identification are found based on the QCL asso- ciation with the SS Block. On the other hand, there is also the possibility of associating PRACH preambles with either CSI-RS or SS Blocks. Once the UE transits the BFRQ, it also monitors for an answer from the gNB SO that it is acknowledged on the receipt of this information. The monitoring for the recovery request response implies the monitoring of the PDCCH with the assumption that this is spatially QCL-ed with the RS of the identified beam. This monitoring is done during a preconfigured time window, and if the UE does not receive any
