Embodiment
Data product process according to transmitting terminal TTI: at first, to all the transmission block concatenated in order in the TTI, carry out code block segmentation according to the size of encoding block then, for the Turbo coding, the full-size of each code block is 5114; Code-aiming block carries out chnnel coding (Turbo coding) then; The data that obtain behind the coding obtain the data of a TTI after through rate-matched for the first time, processing such as rate-matched for the second time.Therefore, include the code block data of one or more code blocks behind the Turbo coding in the data of a TTI, and receiving terminal need carry out channel decoding (Turbo decoding) to these code block data, so among the present invention this code block is obtained data block behind Turbo coding and be called the Turbo decode block.In the TD-SCDMA system, the information that UE (terminal) can receive according to High-Speed Shared Control Channel (HS-SCCH) knows in the data of a TTI to include what Turbo decode block.
The present invention comprises the characteristics of one or more Turbo decode block according to the data of a TTI, when HARQ and channel decoding task are separated in execution, in order to improve the degree of concurrence that terminal side data is handled, save the terminal buffers space, the present invention is when separating the HARQ processing, the each only data block of a Turbo decode block correspondence execution separated rate-matched and bit collection operation for the first time, and will separate each Turbo decode block that for the first time rate-matched and bit collection operation obtain and carry out channel decoding successively, by this pipeline processing mode, can improve the disposal ability of terminal, save the cache resources of terminal simultaneously HS-DSCH.The present invention will be further described by specific embodiment below in conjunction with accompanying drawing.
As shown in Figure 1, the method for described HARQ of separating of the embodiment of the invention and channel decoding may further comprise the steps:
Here,, can after the data of a described TTI are carried out bit separation, data after separating and the soft Bit data that needs to merge be merged, obtain a merging data when needs carry out soft bit when merging; Again described merging data is separated rate adaptation operating for the second time, obtain described first data.
Here, need usually described first data are preserved.If the data of the TTI that this receives make a mistake in follow-up CRC check, then network side need resend these data, when the TTI data that network side resend when terminal are handled, described first data can be merged in the TTI data that resend as soft Bit data.
Here, described channel decoding mode is set according to network channels coded system (as the Turbo coding).Terminal is after obtaining described first data, the number of included Turbo decode block in can data according to a TTI, automatically calculate the particular location of data block in described first data of each Turbo decode block correspondence, and, send to decoding module with of the input of this data block as decoding module.Usually, the quantity of the included Turbo decode block of the data of a TTI may be 1～3.
Here, described decoding module is each only carries out channel decoding to a Turbo decode block.The speed that decoding module is handled the channel decoding of Turbo decoding less than in the step 12 to separate the speed of rate-matched and bit collection operation for the first time corresponding to the data block of this Turbo decode block, promptly whenever obtain a needed time of Turbo decode block in the step 12 less than in the step 13 a Turbo decode block being carried out the required time of channel decoding.
