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: Contention Free Random Access (CFRA) is a procedure used in the random access process, allowing user equipment to initiate communication with the network without contention. It is one of two types of random access procedures supported by the network, the other being Contention-Based Random Access (CBRA). CFRA can be performed using either 2-step or 4-step RA type, depending on network configuration and UE selection.
explanation: CFRA is classified as a Procedure because it defines a specific set of steps and actions taken by user equipment to access the network. The description emphasizes its role in the random access process and how it facilitates communication without contention.
