At User Plane side, the application creates data packets that are processed by protocols such as TCP, UDP and IP. While in the Control Plane, the radio resource control (RRC) protocol handles the signalling messages that are exchanged between the base station and the mobile.
Read moreWhat is user plane latency?
User-plane latency is the lowest time required for transferring a PDU across the physical layer . The lowest time is achieved when the hybrid-ARQ operating point is set such that no hybrid-ARQ retransmissions are required.
Read moreWhat is user plane latency in LTE?
User plane latency is the average time between the first transmission of a data packet and the reception of a physical layer ACK . PRACH parameters impacts control plane latency (attachment operation) and user plane latency. The latency is determinated by the paramtere DRXpaging cycle and RF conditions.
