Embodiment Construction

[0025] Functional Overview

[0026] As mentioned above, in the current process of bit descrambling, HARQ bit decombining, and second rate matching, there are problems of consuming physical resources and reducing data processing efficiency. To solve the above problems, the present invention proposes a bit Descrambling, bit uncombining and second rate matching scheme. This scheme performs HARQ bit decombining on the received data according to the positive and negative conditions of the e value, and then performs bit descrambling and second rate matching on the data. match.

[0027] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

Abstract

The invention discloses a method and a device for bit descrambling, bit demerging and de-secondary rate matching, wherein, the method comprises the following steps: a terminal receives a data flow, the data flow comprises a plurality of data; whether de-HARQ merging needs to be carried out on the data flow or not is judged according to an e value in each minute, thereby determining the data for carrying out the bit descrambling; the bit descrambling is carried out on the data according to a P value which corresponds to the determined data; and de-punching rate matching is carried out on the data flow after that all the data in the data flow carries out the bit descrambling. With the help of the technical scheme, the HARQ bit demerging is carried out on the received data according to the positive situation and the negative situation of the e value, then the bit descrambling and the de-secondary rate matching are carried out on the date, thereby being capable of reducing the occupied physical resources and improving the processing efficiency of the data.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for bit descrambling, bit decombining and second rate matching. Background technique [0002] According to the content stipulated in the 3rd Generation Partnership Project (3rd Generation Partnership Project, referred to as 3GPP) protocol for High Speed ​​Downlink Packet Access (referred to as HSDPA), the bit descrambling processing, During the HARQ bit decombination processing and the second rate matching processing, these three steps of processing are performed in sequence, that is, first, bit descrambling is performed on the data in a Transmission Time Interval (Transmission Time Interval, referred to as TTI), and then Perform HARQ bit decombination, then cache the results after the two steps of processing, save the data into RAM, and finally perform de-rate matching on the data stored in RAM for the second time. [0003] The advantage of the above proces...
