A method performed by a terminal in a wireless communication system is provided that includes transmitting, to a base station, a message A (MsgA) associated with a 2 step random access (RA) procedure, the MsgA including an RA preamble, receiving, from the base station, a message B (MsgB) as a response to the MsgA, identifying whether the 2 step RA procedure is successfully completed, and transmitting, to the base station, hybrid automatic repeat request (HARQ) acknowledge (ACK) information for a transport block (TB) associated with the MsgB, in case that the 2 step RA procedure is successfully completed."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for switching between 2 step and 4 step random access (RA) procedures and contention resolutions","description":"A communication method and system for converging a 5th generation (5G) communication system for supporting higher data rates beyond a 4th generation (4G) system with a technology for Internet of thing","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-12004226","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
