Published: with international search report (Art. 21(3)) (54) Title: RANDOM ACCESS PROCEDURE(S) FOR RADIO SYSTEM (57) : In one of its aspects the technology disclosed herein concerns a communications system comprising an access node (22) and a wireless terminal (26). The wireless terminal comprises receiving circuitry (40) and transmitting circuitry (44) as well as processor circuitry (40). The transmitting circuitry con- figured to transmit a random access preamble configured for a request of sys- tem information. The receiving circuitry configured to receive a random access response. The processor circuitry is configured to consider a reception of the 3 random access response as successful in a case that the random access response comprises a random access preamble identifier (RAPID) corresponding to the transmitted random access preamble, wherein the RAPID is in a medium access control (MAC) subheader. The processor circuitry is configured to consider a random access procedure as successfully completed in a case that a MAC ran- dom access response (MAC RAR) corresponding to the MAC subheader is not included in a MAC protocol data unit (MAC PDU).
