Abstract: A user equipment (UE) may receive, at a packet data convergence protocol (PDCP) layer, a service data unit (SDU) including uplink (UL) data to be transmitted to a base station, and transmit, to the base station, at least one UL transmission including the UL data and timing information associated with an arrival of the SDU at the PDCP layer. The base station may receive the at least one UL transmission including the UL data, identify timing information, and calculate an UL delay based at least in part on the timing information from the UE. The timing information may be communicated in at least one of a PDCP protocol data unit (PDU) header or a medium access control (MAC) control element (CE) (MAC-CE).
