Claim 11:
12. A method, comprising:
receiving by a client device at least one dedicated random access channel, RACH, preamble indication from a network node device having contention free random access, CFRA, resources configured for at least one synchronization signal block, SSB, or at least one channel state information-reference signal, CSI-RS;
triggering, by the client device a random access procedure;
checking, by the client device, whether reference signal received strengths, RSRPs, of at least one SSB and/or of at least one CSI-RS are above, equal to, or below a threshold, wherein at least one SSB or at least one CSI-RS is associated with the CFRA resources;
in response to all the RSRPs being below or equal to the threshold, selecting by the client device an SSB or CSI-RS following a predefined rule, wherein the predefined rule is based on another threshold T2, checking whether any of the RSRPs are above T2, selecting the selected one of the SSB or CSI-RS that has RSRP above the T2, and performing the CFRA on the selected SSB or CSI-RS when the selected SSB or CSI-RS is associated with the CFRA resources; and
in response to the RSRP of any of the SSBs or CSI-RS being above the threshold, performing by the client device the CFRA on one of the SSBs or CSI-RSs that is above the threshold, when the SSBs or the CSI-RSs are associated with the CFRA resources.
