context: with an LTM candidate cell; - RACH-based LTM cell switch. Two types of random access procedure are supported: 4-step RA type with MSG1 and 2-step RA type with MSGA. Both types of RA procedure support contention-based random access (CBRA) and contention-free random access (CFRA) as shown on Figure 9.2.6-1 below. The UE selects the type of random access at initiation of the random access procedure based on network configuration: - when CFRA resources are not configured, an RSRP threshold is used by the UE to select between 2-step RA type and 4-step RA type; - when CFRA resources for 4-step RA type are configured, UE performs random access with 4-step RA type; - when CFRA resources for 2-step RA type are configured, UE performs random access with 2-step RA type. The network does not configure CFRA resources for 4-step and 2-step RA types at the same time for a Bandwidth Part (BWP). CFRA with 2-step RA type is only supported for handover. The MSG1 of the 4-step RA type consists of a
description: The Random Access Procedure is a sequence of network operations used by User Equipment (UE) to initiate communication with the base station in a cellular network. It involves either contention-based or contention-free random access.
explanation: The text describes a specific set of steps and conditions for UE to access the network, aligning with the definition of a procedure.
