description: Acknowledged Mode (AM) is a mode of operation in the Radio Link Control (RLC) sublayer, which ensures that data transmission between the network and user equipment (UE) is acknowledged. This mode provides reliable data transfer by guaranteeing that every packet sent is either successfully received or retransmitted until it reaches its destination.
explanation: AM is classified as a Mode because it describes a specific operational state of the RLC sublayer, influencing how data packets are handled and transmitted between network components. The context provided highlights AM's role in ensuring reliable communication within the 3GPP-specified RRC protocol.
