Problems solved by technology

[0003] According to the existing solution rate matching processing flow, due to the difference in processing speed between the decoding unit and the solution rate matching calculation unit, there is data accumulation between the two, for different bandwidths (1.4Mhz, 3Mhz, 5Mhz, 10Mhz, 15Mhz, 20Mhz), it is necessary to design different solution rate matching units to reduce data accumulation, which increases the complexity of system design and reduces the processing capacity of the system

Abstract

The invention discloses a long term evolution (LTE) rate dematching method. The method comprises the following steps of: establishing a plurality of rate dematching calculation units according to a bandwidth of an LTE system, the data throughput rate of a decoding unit and the data throughput rate of the rate dematching calculation units; distributing a unique identifier for each calculation unit; detecting the identifiers of the rate dematching calculation units in an idle state; if the decoding unit can receive code block data, detecting the receivable data throughput rate of the decoding unit and the data throughput rate of the rate dematching calculation units; acquiring a required number of units according to the receivable data throughput rate of the decoding unit and the data throughput rate of the rate dematching calculation units; and triggering the corresponding number of calculation units for executing rate dematching calculation according to the identifiers of the calculation units in the idle state. The invention also discloses an LTE rate dematching device. By the invention, the systematic design complexity is reduced and the processing capability of the rate dematching is enhanced.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to an LTE rate matching method and device. Background technique [0002] In the LTE (Long Term Evolution, long-term technological evolution) mobile communication system, the focus of solution rate matching is to increase processing speed, reduce processing time, and reduce system complexity. In the entire receiving chain, Turbo decoding is time-consuming. The most modules have different requirements for the decoding ability of the decoder under different bandwidths (1.4Mhz, 3Mhz, 5Mhz, 10Mhz, 15Mhz, 20Mhz). The processing speed of the decoding rate matching unit directly restricts whether the soft bit data can be delivered to the decoding unit in time, thus becoming the key to improving the processing capability of the receiving end. [0003] According to the existing solution rate matching processing flow, due to the difference in processing speed between the decoding u...
