Embodiment Construction

[0055] image 3 It is a flow chart of the data processing method used in the coordinated multi-point transmission system provided by the present invention.

[0056] Such as image 3 As shown, the method includes:

[0057] Step 301 , the network side device recognizes that on the current RE, there is a first coordinated cell that sends data to the user equipment UE and a second coordinated cell that does not send data to the UE exists in the coordinated cluster.

[0058] Step 302: The network side device sends the data signal of the UE and the channel information from the second coordinated cell to the UE in the first coordinated cell according to the channel information from the first coordinated cell to the UE and the channel information from the second coordinated cell to the UE. The equivalent data signal of the UE.

[0059] Wherein, the equivalent data signal is a result obtained by multiplying an equivalent data precoding matrix by a data signal of the UE, and the equi...

Abstract

The application discloses a data processing method, system and device for a coordinated multi-point transmission system. The method includes: the UE demodulates the data signal from the received signal in transparent mode, on the current RE, if there is a first coordinated cell that sends data to the UE in the coordinated cluster, and there is a second coordinated cell that does not send data to the UE Coordinated cell, according to the channel information from the first coordinated cell to the UE and the channel information from the second coordinated cell to the UE, send the data signal of the UE and the equivalent signal from the second coordinated cell to the UE in the first coordinated cell A data signal, wherein the result of the equivalent data signal arriving at the UE through the channel from the first coordinated cell to the UE is different from the result of the UE's data signal passing through the second coordinated cell if the data signal of the UE is sent in the second coordinated cell When the channel from the two coordinated cells to the UE reaches the UE, the result is the same. Applying the present invention can improve the receiving performance of UE.

Description

technical field [0001] The present application relates to the technical field of mobile communication, and in particular to a data processing method, system and device for a coordinated multi-point transmission system. Background technique [0002] Coordinated Multiple Points (CoMP) refers to multiple geographically separated transmission points that cooperate to participate in data transmission for a terminal or jointly receive data sent by a terminal. Multiple transmission points participating in cooperation usually refer to Base stations in different cells. The CoMP technology can reduce inter-cell interference and improve the spectrum efficiency of cell edge users. [0003] In a system applying CoMP technology (referred to as CoMP system), when on the same resource element (ResourceElement, RE), when the cells cooperating with each other send data signals to the same user i, the RE can be called a pure data RE . The downlink channel matrix from user i to cell j can be...
