Problems solved by technology

In the existing scheme, because the number of bits occupied by the constellation point symbols in the width is large, the storage space required for deinterleaving is relatively large. When the deinterleaver is implemented by FPGA, due to the limited storage resources of FPGA itself, it will make this problem more prominent

Embodiment Construction

[0013] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. For the convenience of expression, the LTE system is used as an example for illustration. It is not difficult to understand that the embodiments of the present invention are also applicable to other similar wireless communication systems that have channel deinterleaving processing.

[0014] see figure 2 , figure 2 It is a schematic flowchart of a method for processing uplink data provided by an embodiment of the present invention. In this embodiment, the processing of uplink data can be completed on a PUSCH (Physical Uplink Shared Channel, uplink shared physical channel). The method mainly includes the following steps.

[0015] Step 202, performing deinterleaving processing on the constellation point symbols.

[0016] After receiving uplink data such as constellation point symbols, deinterleave processing is performed on the constellation point sy...

Abstract

The embodiment of the invention provides an uplink data processing device, which comprises a de-interleaving module, a conversion module and a de-multiplexing module, wherein the de-interleaving module is used for de-interleaving received uplink constellation-point symbols; the conversion module is used for converting the de-interlaced constellation-point symbols into soft bits; and the de-multiplexing module is used for de-multiplexing the soft bits and outputting the soft bits. The device provided by the embodiment of the invention can save storage space in the de-interleaving module. Besides, the embodiment of the invention also provides an uplink data processing method.

Description

technical field [0001] The embodiment of the present invention relates to the field of wireless communication, in particular to a method and device for processing uplink data and a base station. Background technique [0002] In a wireless communication system such as an LTE (Long Time Evolution, long-term evolution) system, when processing received uplink user data such as constellation point symbols, an implementation scheme is as follows figure 1 As shown, it mainly includes the following processes. Perform channel compensation on the received data, then perform demodulation processing, descrambling processing, and then perform deinterleaving processing and demultiplexing processing, and then output to subsequent processing modules, such as business data processing modules and CQI (channel quality indicator) decoding module. [0003] Usually, the deinterleaver is a simple row-column deinterleaver, implemented by FPGA (Field Programmable Gate Array, Field Programmable Gat...
