Abstract

The embodiment of the invention discloses an HARQ receiving method and a device thereof, which relate to the field of wireless communication and can solve the problem of slow processing speed of the existing HARQ realization function. The HARQ receiving device of the embodiment of the invention comprises a bit collection unit used for reading a bit sequence after deinterlacing, finishing address conversion and outputting the bit sequence; a second time rate matching unit used for conducting rate matching for the second time to the bit sequence output by the bit collection unit; a storage unitused for storing the bit sequence output by the second time rate matching unit, controlling and parallel outputting the system bit of a first time rate matching, the first parity bit of the first time rate matching and the second parity bit of the first time rate matching; and a first time rate matching unit used for conducting parallel first time rate matching to the bits output by the storage unit. The embodiment of the invention is suitable to HARQ technology.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a method and device for receiving a hybrid automatic repeat request. Background technique [0002] HSDPA (High Speed ​​Downlink Packet Access, High Speed ​​Downlink Packet Access) is used to realize WCDMA (Wideband Code Division Multiple Access, Wideband Code Division Multiple Access) network high-speed downlink data service, which can make the downlink data rate reach 8-10Mbps. For the HSDPA system adopting MIMO (Multiple-Input Multiple-Out-put) technology, the data rate can reach 20Mbps. In the technical scheme of HSDPA, the key technologies involved mainly include four kinds: adaptive coding and modulation, HARQ (Hybrid-ARQ, hybrid automatic repeat request) technology, FCS (Frame Check Sequence, fast cell selection), MIMO antenna processing. [0003] The definition of the HARQ mechanism itself is an error control scheme that combines FEC (Forward Error Correction, forwar...
