full_form: Unacknowledged Mode
context: one for target cell), four UM RLC entities (two for each direction on source cell and target cell), or two AM RLC entities (one for source cell and one for target cell); - For UM MRBs, each PDCP entity is associated with one UM RLC entity (for MTCH or for downlink DTCH), two UM RLC entities (one for MTCH and one for downlink DTCH, or one for downlink DTCH and one for uplink DTCH), or three UM RLC entities (one for MTCH, one for downlink DTCH, and one for uplink DTCH); - For AM MRBs, each PDCP entity is associated with one AM RLC entity (for downlink DTCH and uplink DTCH), or one UM RLC entity (for MTCH) and one AM RLC entity (for downlink DTCH and uplink DTCH); - For MP split bearers with SL indirect path, each PDCP entity is associated with one or more Uu RLC entities and one SRAP entity; - For MP split bearers with N3C indirect path, each PDCP entity is associated with one or more Uu RLC entities and the N3C; - Otherwise, each PDCP entity is associated with one UM RLC entity, two UM
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 description explicitly states UM as a 'transmission mode' within RLC, defining its function in controlling data transfer characteristics.
