Embodiment Construction

[0040] As described in the background, in the current research process of the rate matching of the LTE-A system, there is a solution in which the size of the buffer in the terminal device is different from the size of the buffer in the de-rate matching device at the base station. Under this scheme, how the terminal device stores the encoded block data has not yet been determined.

[0041] Therefore, in order to solve such problems, the present invention proposes a corresponding data transmission scheme based on the fact that the size of the buffer in the terminal device is different from that in the derate matching device at the base station.

[0042] Such as Figure 5 As shown, it is a schematic flow chart of a coding block storage method proposed by an embodiment of the present invention, and the method specifically includes the following steps:

[0043] Step S501, the terminal device decodes the received encoded block sent by the base station.

[0044] Step S502. When the...

Abstract

The embodiment of the invention discloses a method and a device for storing an encoding block. By applying the technical scheme provided by the embodiment of the invention and aiming at the condition that the size of a buffer in terminal equipment is smaller than that of a buffer in a speed matcher at a base station end, a scheme for storing an encoding block bit in the buffer by the terminal equipment under the condition of encoding failure of the encoding block is provided, so as to definite a solution for the condition that the size of the buffer in the terminal equipment is smaller than the that of the buffer in the speed matcher. The problem that a corresponding solution is absent under such a condition is solved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a coding block storage method and device. Background technique [0002] LTE (Long Term Evolution, Long Term Evolution) Rel-8 (Version 8) system needs to consider various transmission code rates and modulation methods in order to support efficient and flexible transmission methods, taking into account HARQ (Hybrid Automatic Repeat reQuest, Hybrid Automatic Repeat reQuest, transmission request) technology and link adaptive technology. [0003] To this end, the LTE system uses a method of puncturing or repeating to extract a predetermined length of bit sequence from the coded bit stream, and this process is called rate matching. [0004] In the LTE system, the code rate of the Turbo coder used in the traffic channel is 1 / 3. The system bit stream, the first parity bit stream and the second parity bit stream output by the turbo encoder are respectively and independent...
