HARQ is used in HSDPA and HSUPA which provide high speed data transmission (on downlink and uplink, respectively) for mobile phone networks such as UMTS, and in the IEEE 802.16-2005 standard for mobile broadband wireless access, also known as "mobile WiMAX". It is also used in Evolution-Data Optimized and LTE wireless networks.

Type I Hybrid ARQ is used in ITU-T, a high-speed Local area network standard that can operate at data rates up to 1 Gbit/s over existing home wiring (power lines, phone lines and coaxial cables). uses CRC-32C for Error Detection, LDPC for Forward Error Correction and Selective Repeat for ARQ.

In LTE handover procedure, after UE handover to the target cell, if new TAI is not in the TAI list, the TAU will be triggered.

In HO procedure, UL/DL data has been handover to the target cell.

But before TAU, the UE doesn't register to the new MME, in the new cell, how the the DL/UL data transfer between UE and network(S-GW / P-GW) before TAU and after HO.

Also, as we know, if the TAU fails, the DL/UL data transfer will be interrupted, which network element will release the DL/UL throughput?
