The random access configuration comprises one or more associations of a synchronization signal block (SSB), a preamble sequence, and physical random access channel (PRACH) configuration resources. The PRACH resources comprise time domain resources and frequency domain resources. The method further comprises receiving one or more SSBs; selecting one of the one or more received SSBs; and selecting a preamble sequence. The preamble sequence is associated with the selected SSB in the random access configuration. The method further comprises transmitting the selected preamble sequence on PRACH resources associated with the selected SSB in the random access configuration. In particular embodiments, more than one SSB is associated with identical PRACH resources, and the preamble sequence associated with each of the more than one SSBs identifies the SSB with respect to the PRACH resources."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Contention-free random access with multiple SSB","description":"According to some embodiments, a method in a wireless device of performing random access comprises receiving a random access configuration.
