Embodiment Construction

[0057] The technical solutions of the present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.

[0058] Embodiments of the present invention provide a device and method for implementing de-rate matching for LTE traffic channels including HARQ combining. In this embodiment, the system sends the rate matching parameters of the transport block (TB) and the HARQ combination parameters to the device; the device reads the new data and historical data to be processed from the system through the data bus, and writes the HARQ combination result ; Each data soft symbol occupies one byte.

[0059] A device for solving rate matching in the embodiment of the present invention is as follows: Figure 5 As shown, it mainly includes:

[0060] The parameter processing and control module 501 is used to obtain and distribute task parameters; the task parameters are in TB, and the parameter processing and control module 501 analyz...

Abstract

The present invention discloses a rate dematching method, device and receiving-side apparatus, the method comprising: acquiring new data awaiting processing and, on the basis of said new data awaiting processing, executing bit recovery / bit separation, obtaining post-bit recovery / bit separation data and writing same into a code block data storage unit; engaging in sub-block deinterleaving processing in regard to the data stored in the code block data storage unit; engaging in the hybrid automatic retransmission request (HARQ) consolidation processing of the output data which underwent sub-block deinterleaving processing and of acquired history data awaiting processing, and outputting HARQ consolidation results.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method, device and receiving side equipment for de-rate matching. Background technique [0002] Long Term Evolution (LTE, Long Term Evolution) is the evolution of the third-generation mobile communication (3G, 3rd-Generation) technology, which improves and enhances 3G air access technology, and uses Orthogonal Frequency Division Multiplexing (OFDM, Division Multiplexing) and Multiple-Input Multiple-Output (MIMO, Multiple-Input Multiple-Output) technology-based new-generation wireless network can provide peak rates of downlink 100Mbit / s and uplink 50Mbit / s under 20MHZ spectrum bandwidth, improving the The performance of edge users improves cell capacity and spectrum utilization, and reduces system delay. According to the LTE technical standard 3GPP TS36.211 / 3GPP TS36.212 protocol document, for the LTE uplink and downlink traffic channels, the processing flow of the transmittin...
