Problems solved by technology

Usually, after receiving all the bits sent by the sender, the receiving end combines the Hybrid Automatic Repeat reQuest (HARQ) to uniformly rearrange all the received bits; this process will not only increase the delay consumption but also Will increase the storage consumption of the address space

Abstract

An embodiment of the present application provides a method and device for de-rate matching, the method includes: a decoding end receives N bits of data sent by an encoding end, wherein the data after the encoding end performs rate matching includes X bits of data, X bits of data are sent from the encoding end to the decoding end through M times, and N bits of data are sent each time, the X, M and N are positive integers, the X is greater than or equal to the N, and the calculation is performed in parallel The storage addresses corresponding to the N bits of data are stored in the corresponding storage addresses respectively. Through the embodiments of the present application, the decoding end can calculate the de-rate matching address of the received data in parallel in real time, thereby improving the de-rate matching efficiency of the decoding end without consuming additional address buffer space.

Description

technical field [0001] The present application relates to the field of communications, and in particular, to a method and apparatus for de-rate matching. Background technique [0002] Usually, after the transmitting end encodes the data, the number of bits of the encoded data may not match the number of bits that can be provided by the physical channel of the transmitting end; for example, the number of bits of the encoded data is 1788. (Quadrature Phase Shift Keying, Quadrature Phase Shift Keying) modulation mode, the number of bits that a physical channel can carry is 1728 bits. Therefore, the transmitting end can match the rate of the encoded data, so that the encoded data matches the number of bits that can be provided by the physical channel. [0003] The rate matching means that bits on the transmission channel are repeated or punctured. Punching is to knock out the current bit, and at the same time move the following bits forward by one. To repeat is to insert the ...
