Abstract
An adaptive downlink Coordinated Multi-Points (CoMP) transmission method and device are provided. The method includes: determining each coordinating cell corresponding to the serving cell of the downlink CoMP User Equipment (UE); counting the cell load value of each coordinating cell; on the basis of the cell load value of each coordinating cell, determining the transmission manner adopted by each coordinating cell for the downlink CoMP UE, and counting the number of coordinating cells corresponding to each transmission manner; and on the basis of the number of coordinating cells corresponding to each transmission manner, determining the transmission manner of the downlink CoMP UE.
Claims10
A method for adaptive downlink Coordinated Multi-Point (CoMP) transmission, applied at a base station side, the method comprising:
- determining each coordinating cell corresponding to a serving cell of a downlink CoMP User Equipment (UE);
- calculating a cell load value of each cooperating cell;
- determining a transmission mode to be applied to the downlink CoMP UE in each cooperating cell based upon the cell load value of each cooperating cell, and calculating the number of cooperating cells corresponding to each transmission mode;
- and
- determining a transmission mode of the downlink CoMP UE based upon the number of cooperating cells corresponding to each transmission mode;
- wherein the calculating the cell load value of each cooperating cell comprises:
- calculating the number of Physical Resource Blocks (PRBs) required for transmitting a downlink service in each cooperating cell, and the number of available PRBs of each cooperating cell, and calculating a ratio of the number of PRBs required for transmitting a downlink service in each cooperating cell to the number of available PRBs of the same cooperating cell respectively, to obtain the cell load value of each cooperating cell.
An apparatus for adaptive downlink CoMP transmission, applied at a base station side, the apparatus comprising:
- a memory, configured to store at least one instruction;
- a processor, configured to execute the at least one instruction to:
- determine a transmission mode to be applied to the downlink CoMP UE in each cooperating cell based upon the cell load value of each cooperating cell;
- calculate the number of cooperating cells corresponding to each transmission mode;
- determine a transmission mode of the downlink CoMP UE based upon the number of cooperating cells corresponding to each transmission mode;
- and
- calculate the number of PRBs required for transmitting a downlink service in each cooperating cell, and the number of available PRBs of each cooperating cell, and calculate a ratio of the number of PRBs required for transmitting a downlink service in each cooperating cell to the number of available PRBs of the same cooperating cell respectively, to obtain the cell load value of each cooperating cell.
