name: UM
full_form: Unacknowledged Mode
context: an SCG failure occurs shortly after a successful SN change from a source SN to a target SN or a SN change failure occurs during the SN change procedure; the MN makes decisions for UE, making UE to re-establish the radio link connection in the source SN. - Failures due to change to wrong SN triggering: an SCG failure occurs shortly after a successful SN change from a source SN to a target SN or a SN change failure occurs during the SN change procedure; the MN makes decisions for UE, making UE to establish the radio link connection in a SN other than the source SN or target SN. The detection solution enabled by the RLF Indication and HO Report procedures can be reused, the corresponding messages may be signalled between the MN and SN, and/or among the involved SNs. - In case of MN trigger SN change, MN can obtain the SCG failure information from UE directly when SCG RLF occurs. - In case of SN trigger SN change, MN should inform the SN about the SN change failure to help SN adjust SN
description: Unacknowledged Mode (UM) is a transmission mode in Radio Link Control (RLC) where data is sent without expecting an acknowledgement from the receiver. This mode prioritizes speed and throughput over guaranteed delivery, making it suitable for applications where occasional data loss is acceptable.
explanation: The text explicitly refers to UM as a 'transmission mode' within the RLC protocol. It describes its function of sending data without waiting for confirmation, aligning with the characteristics of transmission modes that define how data is transferred.
