name: RA
full_form: Routing Area
context: with 2-step RACH is only supported for handover. 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. In case of random access in a cell configured with SUL, UE performs carrier selection (between SUL and NUL) before selecting between 2-step and 4-step RA type. MSGA structure: PRACH The MSGA in 2-step RACH comprise a PRACH and a PUSCH. The PRACH resources for 2-step RACH in time/frequency domain can be either shared with 4-step RACH or can be configured to be separate. All the preamble formats and the PRACH configuration indexes defined in Rel-15 and in Rel-16 NR-U and TEI can be used. In
description: The term 'RA' refers to Random Access, a procedure used by the User Equipment (UE) to initiate communication with the network. It involves the UE selecting a random access type based on network configuration and performing carrier selection before choosing between 2-step and 4-step RA types.
explanation: The context provided describes 'RA' in relation to a specific procedure within telecommunications, not as a defined protocol, network element, or function. Therefore, it is classified as Miscellaneous.
