Problems solved by technology

[0010] The purpose of the present invention is to solve the problem that the transmission format set of the E-DCH channel changes before and after the above TFCS reconfiguration, and the E-DCH transmission format used for the first transmission corresponding to the retransmission data does not exist in the E-DCH channel after the TFCS reconfiguration In the TFS, resulting in the problem that the retransmitted data cannot be decoded correctly

Embodiment Construction

[0054] There are three options for HARQ retransmission to operate correctly in the case of TFCS reconfiguration, option 1:

[0055] The basic idea of ​​option 1 is as follows figure 1 shown. The UE receives a TFCS reconfiguration command from the RNC; before the TFCS reconfiguration process is activated, the UE continues to use the TFCS specified by the RNC before the TFCS reconfiguration is activated (hereinafter referred to as the old TFCS, and the TFCS specified by the RNC after the TFCS reconfiguration is activated is referred to as the new one). TFCS) sends new data and retransmission data; when TFCS reconfiguration occurs, if there is an unfinished physical layer retransmission, then if the E-DCH transmission format used for the first transmission corresponding to the retransmission data does not exist in TFCS reconfiguration After the E-DCH transmission format is centralized, the NodeB and UE remember the two TFCS tables before and after the TFCS reconfiguration respec...

Abstract

A method for operating EUDCH under the conditions of re-allocate TFCS comprises the steps of: UE receives the TFCS re-allocate command from RNC, UE and Node B separately store TFCS tables that before and after the re-allocation; before activating the TFCS re-allocate process, UE goes on using the TFCS before the re-allocation and active to send new data and re-send data. Node B goes on using TFCS before the re-allocation and active to receive new data and re-send data; when the re-allocation of TFCS happens, if the not-yet-completed physical layer re-sending exists, and the E-DCH transmission formation that have been used in the first transmission doesn't exist in the E-DCH transmission formation set that after the TFCS re-allocation, then during the time T of re-allocating TFCS, the new and old TFCS are valid at the same time. In active time T of the TFCS re-allocation process, the old TFCS table in UE and Node B will be released, or delete the old TFCS table during the process of re-allocating TFCS.

Description

technical field [0001] The present invention relates to the third generation of mobile communication, in particular to the operation method of HARQ retransmission and corresponding equipment in the process of transmission format combination set reconfiguration (TFCS reconfiguration) in the Enhanced Uplink Dedicated Channel (EUDCH) of WCDMA system. Background technique [0002] The 3rd Generation Partnership Project (The 3 rd The Generation Partnership Project (3GPP for short) carries out the standardization work of the third-generation mobile communication. In the WCDMA (Wide-Band Code Division Multiple Access) Release6 version, the enhanced uplink dedicated channel (Enhancement for Uplink Dedicated Channel (EUDCH) for short) is being studied. Refer to TR25. 896. The purpose of the EUDCH is to improve the uplink capacity and coverage of the system through the effective management and planning of the uplink transmission resources through the wireless network, especially to ...
