Description
Technical field
The present invention relates to wireless technical field, relate in particular to communication means, base station and a kind of communication system in a kind of multi-carrier mobile communication system.
Background technology
There is very big difference in mobile communication system for the data rate that center of housing estate and Cell Edge User provide, the data rate that the data rate that Cell Center User is enjoyed is enjoyed than Cell Edge User is much higher, therefore, the service experience of Cell Edge User is far below the service experience of Cell Center User.And for the actual operation of network, if wish to obtain higher user satisfaction, just must consider to improve service quality to Cell Edge User, promptly offer the data rate of Cell Edge User, and multi-transceiver technology has obtained application as the key technology that improves Cell Edge User service quality, for example the carrier time division high speed downlink packet inserts (TD-HSDPA, Time Division-High Speed Downlink Packet Access), two carrier waves of HSDPA (Dual Cell) and more the carrier aggregation (Carrier Aggregation) of Long Term Evolution (LTE-Advanced, Long TermEvolution-Advanced) all belong to multi-transceiver technology.
In the present multi-carrier mobile communication system carrier wave and arrangement of antennas be adopt the overlapping covering of multicarrier mode (for example, dual cell among the HSDPA adopts this mode), the transmitting antenna that promptly belongs to the different carrier of same base station is total to location (or transmitting antenna is identical), Fig. 1 shows the collocation method schematic diagram that adopts two overlapping coverage modes of carrier wave under a kind of omni-directional antenna case of simplification, as seen from Figure 1, under this configuration mode, the transmitting antenna that belongs to the different carrier of same base station (NodeB) is total to the location, promptly all sends all carrier waves on each transmitting antenna.Compare with the single carrier mobile communication system, adopt the multi-carrier mobile communication system of this arrangements can be similar to the data rate that increases exponentially Cell Edge User, improve the service experience of Cell Edge User.
Yet, though this scheme has improved the data rate of Cell Edge User by multi-carrier polymerizing, but because the transmitting antenna of the different carrier of same base station shared (perhaps being total to the location), so the while has also increased exponentially the data rate of Cell Center User, thereby causes the difference between the two not fall counter increasing.For example, compare with single carrier, after mobile communication system adopted the overlapping covering of N carrier aggregation, the data rate of Cell Edge User and Cell Center User all can be similar to be thought and has improved N doubly, and the difference of the data rate that provides in the whole sub-district (variance) is to have increased N2 doubly.As seen,, but increased network provides service on different geographic regions difference, caused the service-conformance variation of mobile communication system on the geographic area though the overlapping covering of multicarrier has improved the data rate of Cell Edge User.And for the actual operation of network, the service that uniform quality is provided on different geographic regions is very important, this is because as user during from the center of housing estate regional movement to cell edge, the remarkable decline of the data rate of its acquisition will cause increasing sharply of user's dissatisfaction.
In addition, in LTE-Advanced, relaying (Relay) technology is also fully studied as solving the lower problem of cell edge data rate at present.The Relay technology mainly is to arrange some relay stations at the cell edge place, then is connected with relay station when the user moves to cell edge region, and then by relay station data is returned to the base station.But the relay station of being arranged needs to have complicated function sometimes, so implementation process is complicated.
