Embodiment 1
[0037] An uplink coordinated multi-point data decoding method provided by an embodiment of the present invention is introduced in detail.
[0038] refer to figure 2 , shows a flow chart of an uplink coordinated multi-point 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 cooperating cell in step 100 above belong to the set of uplink CoMP cells corresponding to the terminal sending uplink data, and the set of uplink CoMP cells corresponding to the terminal can be determined through the information reported by the terminal and the measurement data of the base station.
[0041] Multiple coordinated cells can receive the uplink data of the same terminal, and the primary cell can receive constellation point information from multiple coordinated cells.
[0042] Wherein, the data volume of the constellation point information is sm...
Embodiment 2
[0052] An uplink coordinated multi-point data decoding method provided by an embodiment of the present invention is introduced in detail.
[0053] refer to Figure 5 , shows a flow chart of an uplink coordinated multi-point data decoding method in an embodiment of the present invention.
[0054] Step 200, selecting a set of uplink CoMP cells corresponding to the terminal.
[0055] Preferably, the uplink CoMP cell set corresponding to the terminal is selected through information reporting of the terminal and measurement data of the base station.
[0056] The uplink CoMP cell set corresponding to the terminal may include a coordinated cell and a primary cell.
[0057] During network planning, the current cell and several neighboring cells are planned as a set of CoMP cells. The basis for the base station to select the corresponding cooperative cell of a certain terminal is the strongest neighboring cell indicated in the A3 measurement reported by the terminal, or the base stati...
Embodiment 3
[0078] An uplink coordinated multi-point data decoding device provided by an embodiment of the present invention is introduced in detail.
[0079] refer to Figure 6 , shows a schematic structural diagram of an uplink coordinated multi-point data decoding device in an embodiment of the present invention.
[0080] The uplink coordinated multipoint data decoding device may be located in the main cell, and the uplink coordinated multipoint data decoding device may specifically include: a receiving module 30 , a combining module 32 and a decoding module 34 .
[0081] The functions of each module and the relationship between each module are introduced in detail below.
[0082] The receiving module 30 is configured to receive constellation point information from a coordinated cell; wherein, the data amount of the constellation point information is smaller than the data amount of uplink data received by the coordinated cell. The uplink data may be received by the coordinated cell a...
