Problems solved by technology

[0049] It can be seen from the above-mentioned technical solutions of the prior art that according to the current agreement, the E-TFCS set of E-DCH must support the complete set of the specified transmission parameter table, and the maximum value of E-TFCI must be supported up to 127, although according to Iucent The CR (bit mapping of E_DPCCH) has changed the bit mapping order, but it still cannot achieve the purpose of reducing the complexity of E-DPCCH decoding, unless the value range of E-TFCI is artificially limited, but a huge rate limit has to be paid

Embodiment Construction

[0078] The present invention provides a method for decoding and processing the E-DPCCH, the core of which is: firstly define the E-TFCS set in the information element in the E-TFCS information of the E-DCH sent by the RNC to the NodeB and UE size; then the base station decodes the information in the E-DPCCH based on the size of the defined E-TFCS set. The invention can optimize the E-DPCCH decoding algorithm and improve the decoding speed by modifying the cell definition mode of the E-TFCS information of the E-DCH.

[0079] The implementation process of the first embodiment provided by the present invention, such as figure 2 shown, including:

[0080] Step 101, the base station acquires E-TFCS information of the E-DCH delivered by the RNC to the NodeB and the UE.

[0081] The present invention modifies the information elements in the E-TFCS information of the E-DCH sent by the RNC to the NodeB and the UE, that is, the size of the E-TFCS set and the transmission format index...

Abstract

The invention relates to a method to take decode process that includes the following steps: defining the size of E-TFCS collection in E-TFCS information of E-DCH sending to NodeB and UE under RNC; taking decoding process to the information in E-DPCCh. The invention could flexibly configure the E-TFCS information in E-DCH and simplify the decoding process for E-DPCCH, improve decoding speed and would not influence capability grade of UE.

Description

technical field [0001] The present invention relates to the communication field, in particular to a decoding processing method. Background technique [0002] WCDMA R6 version introduces HSUPA (High Speed ​​Uplink Packet Access) technology, and adds E-DPCCH (E-DCH Dedicated Physical Control Channel) and E-DPDCH (E-DCH Dedicated Physical Data Channel) in the uplink. The following control information is carried in the E-DPCCH: [0003] Retransmission Sequence Number (RSN): xrsn, 1, xrsn, 2 [0004] E-TFCI information (E-DCH transmission format combination indication): xtfci, 1, xtfci, 2, ..., xtfci, 7 "Happy" bits: xh, 1 [0005] During the communication process, firstly, the UE (user equipment) encodes the control information in the E-DPCCH, and then transmits the encoded information and the data in the E-DPDCH to the (base station) through a wireless channel, The NodeB decodes the information in the E-DPCCH according to the E-TFCS (E-DCH Transport Format Combination Set) i...
