Wireless communication method and user equipment for random access operations

A User Equipment (UE) comprising:

• at least one processor;
• and
• at least one memory coupled to the at least one processor, wherein the at least one memory stores computer-executable instructions that, when executed by the at least one processor, cause the UE to:
• receive, from a Base Station (BS), a Radio Resource Control (RRC) reconfiguration message including information related to a reconfiguration with synchronization, the information including a Contention Free Random Access (CFRA) configuration for a 2-step Random Access (RA), the CFRA configuration configuring a resource and a maximum number of Message-A (MSGA) preamble transmissions;
• start a timer upon receiving the RRC reconfiguration message including the information related to the reconfiguration with synchronization, the timer being configured by the information;
• initiate an RA procedure after starting the timer, with an RA type set to a 2-step RA type, for the reconfiguration with synchronization, the RA procedure comprising transmitting an MSGA preamble;
• discard the resource in a case that a value of a preamble transmission counter reaches the maximum number of MSGA preamble transmissions;
• discard the resource in a case that the timer expires;
• and
• discard the resource in a case that the UE sets the RA type from the 2-step RA type to a 4-step RA type for the RA procedure.
