FIG. 6 illustrates target RU 412, DU 414, and CU 416 to handover wireless UE 401 that executes the low-latency application. RU 412, DU 414, and CU 416 comprises an example of wireless access node 112, although node 112 may differ. Target RU 412 comprises antennas, amplifiers, filters, modulation, analog-to-digital interfaces, DSP, memory, and transceivers (XCVRs) that are coupled over bus circuitry. Target DU 414 comprises memory, CPU, and transceivers that are coupled over bus circuitry. The memory in target DU 414 stores an operating system and 5GNR network applications like Physical Layer (PHY), Media Access Control (MAC), and Radio Link Control (RLC). Target CU 416 comprises memory, CPU, and transceivers that are coupled over bus circuitry. The memory in target CU 414 stores an operating system and network functions like UPF 432, ASF 434, Packet Data Convergence Protocol Function (PDCPF) 611, Service Data Adaptation Protocol Function (SDAPF) 612, and Radio Resource Control Function (RRCF) 613.

In target DU 414, RLC functions comprise ARQ, sequence numbering and resequencing, segmentation and re-segmentation. MAC functions comprise buffer status, power control, channel quality, HARQ, user identification, random access, user scheduling, and QoS. PHY functions comprise packet formation/deformation, guard-insertion/guard-deletion, parsing/de-parsing, control insertion/removal, interleaving/de-interleaving, FEC encoding/decoding, channel coding/decoding, channel estimation/equalization, and rate matching/de-matching, scrambling/descrambling, modulation mapping/de-mapping, layer mapping/de-mapping, precoding, RE mapping/de-mapping, FFTs/IFFTs, and DFTs/IDFTs.
