Embodiment 1

[0037] Introduce in detail an uplink coordinated multi-point data decoding method provided by an embodiment of the present invention.

[0038] Reference figure 2 , Shows a flowchart of an uplink coordinated multipoint data decoding method in an embodiment of the present invention.

[0039] Step 100: The primary cell receives constellation point information from the coordinated cell.

[0040] The primary cell and the coordinated cell in the above step 100 belong to the uplink CoMP cell set corresponding to the terminal sending the uplink data, and the uplink CoMP cell set corresponding to the terminal can be determined by the information report of the terminal and the measurement data of the base station.

[0041] Multiple coordinated cells can receive uplink data from the same terminal, and the primary cell can receive constellation point information from multiple coordinated cells.

[0042] Wherein, the data amount of the constellation point information is smaller than the data amount...

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 a data decoding method and equipment for uplink coordinated multipoint. Background technique [0002] The processing flow of the Physical Uplink Shared Channel (PUSCH) includes 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 the 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 primary cell (the cell where the terminal resides). When the cell is in signal equalization, the uplink data is processed ...
