Embodiment Construction

[0071] see Figure 3A , the present invention provides a method for realizing hybrid automatic request retransmission processing, and its specific implementation process is as follows:

[0072] Step 301: Segment the transmission block into code blocks;

[0073] At the sending end, after the transmission block is segmented into code blocks, the transmission block includes more than two code blocks;

[0074] Step 302: Store part of the transmission block in coded blocks that have undergone channel coding each time;

[0075] Step 303: Take out the stored coded block, perform bit separation on the coded block, and generate a rate matching parameter for the coded block after bit separation, and use the rate matching parameter to perform the first rate matching on the coded block;

[0076] Step 304: When the transmission block completes the first rate matching, perform code block concatenation on the coding block that has completed the first rate matching.

[0077] Preferably, when...

Abstract

The invention discloses a method for realizing hybrid automatic repeat request and a method for realizing channel decoding. The method is as follows: a coding block after channel decoding of a transmission block part is stored each time on a sending end; the stored coding block is taken out and subject to bit separation and first velocity matching; when first velocity matching of a transmission block is completed, code block cascade connection of the coding block after completion of first velocity matching is performed; first velocity de-matching and bit de-separation are performed on a partial coding block of an HARQ process data each time on a receiving end, and the coding block after bit de-separation is stored; the stored coding block is taken out and subject to channel decoding. The invention also discloses a system for realizing HARQ processing and a system for realizing channel decoding. By adoption of the system for realizing HARQ processing and the system for realizing channeldecoding, data storage space required between coding / decoding and HARQ processing / de-HARQ processing can be saved.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a method and system for realizing hybrid automatic retransmission processing and channel decoding. Background technique [0002] High Speed ​​Downlink Package Access (HSDPA) technology is proposed in the fifth version of the 3rd Generation Partnership Project (3GPP) to improve the throughput of downlink business data It is an important technology of the transmission rate of service data and the main breakthrough point of the fifth version (R5) relative to the ninety-ninth version (R99) and the fourth version (R4). Utilizing HSDPA technology, performances such as high throughput, small delay and high peak data transmission rate of downlink business data can be realized. Because HSDPA is backward compatible with R99 and R4, operators can smoothly upgrade according to the needs of network construction and development without affecting existing users. [0003] HSDPA ...
