Abstract

The invention provides data decoding method and equipment with uplink coordinated multiple points. The data decoding method comprises the following steps: a main district receives constellation point information from a cooperation district, wherein the data quantity of the constellation point information is smaller than that of uplink data received by the cooperation district; the main district carries out weighted combination on the constellation point information to obtain combined constellation point information; and the main district carries out demodulation and decoding on the combined constellation point information to obtain original information. With the adoption of the technical scheme of the invention, the data transmission cost between the main district and the cooperation district is reduced, the problem that the gain is lowered caused by decoding soft bits after being combined is solved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an uplink coordinated multi-point data decoding method and equipment. Background technique [0002] The processing flow of the uplink physical uplink shared channel (Physical Uplink Shared Channel, PUSCH), including the processing steps and output results of each stage, such as figure 1 shown. The main process is: input uplink data, perform channel estimation and equalization operations to generate constellation point information, demodulate the constellation point information to generate soft bits, and then decode the soft bits to obtain original data. [0003] In the current Long Term Evolution (LTE) uplink Coordinated Multiple Points (CoMP) transmission technology, the method of combining uplink data is usually adopted, that is, the coordinated cell transmits the uplink data to the main cell (the cell where the terminal resides), When the main cell is equalizi...
