Problems solved by technology
[0012] Since the adjacent cell with the strongest signal does not send signals on the corresponding resource block, although this improves the performance of the cell border users, it occupies the resources of the adjacent cell, which will lead to a decrease in system throughput.

Embodiment Construction
[0057] The method of the embodiment of the present invention is as figure 1 shown, including:
[0058] Step 11, based on the dynamic cell selection technology, the user equipment selects the first cell on the resource block;
[0059] Step 12, when the user equipment is a cell edge user equipment of the first cell, the user equipment calculates a first throughput and a second throughput on the resource block according to a measurement result;
[0060] The first throughput and the second throughput are throughputs that can be achieved by the user equipment using the resource block in silent mode and normal mode, respectively;
[0061] In silent mode, if the cell with the strongest instantaneous received power allocates resource blocks to the user equipment, and the user equipment is a cell-edge user equipment of the serving cell, the cell with the second highest instantaneous received power will not allocate the resource block to the user, and the transmit power of the base st...

The invention provides a method for scheduling resources among cells, base stations, user equipment and a mobile communication system, and can increase the throughput of the system. The method is applied to the mobile communication system and comprises the following steps of: selecting a first cell on a resource block; calculating first throughput and second throughput of the user equipment on the resource block when the user equipment is cell edge user equipment of the first cell, wherein the first throughput and the second throughput are the throughput of the user equipment on the resource block under a muting mode and a normal mode respectively; judging whether the first throughput is more than N times of the second throughput or not and acquiring a judgment result, wherein the N is the number of the base stations which provide wireless communication service for the user equipment under the muting mode; if the judgment result indicates that the first throughput is more than or equal to N times of the second throughput, indicating the base station belonging to the first cell to use the muting mode on the resource block; and if the judgment result indicates that the first throughput is not more than N times of the second throughput, indicating the base station belonging to the first cell not to use the muting mode on the resource block. The invention can increase the throughput of the system.
Description
technical field [0001] The present invention relates to multi-point coordinated transmission and reception technology in 3GPP LTE-A, in particular to a resource scheduling method between cells, a base station, user equipment and a mobile communication system. Background technique [0002] Multi-point coordinated transmission and reception is a key technology for controlling inter-cell interference in the LTE-A system. It realizes joint transmission and reception between multiple cells, and can effectively control or eliminate interference between adjacent cells, especially for cells The improvement of edge user performance is a key technology. Specifically, according to the complexity of the transmission technology and the amount of feedback overhead, the above technologies can be further divided into coordinated scheduling, coordinated beamforming and joint processing technologies. Joint processing technology can be further divided into joint transmission technology and dy...
