Reduce cell between it is this interfere with each other, 3GPP introduces coordinated multipoint transmission (Coordinated in R11 versions
Multiple Points, CoMP) technology.
In downlink CoMP, the SRS signal that CoMP UE are sent is received simultaneously in serving cell and cooperation cell, by
In the SRS resource of CoMP UE and the SRS resource of cooperation cell UE be generally non-orthogonal or cooperation cell UE and CoMP UE are in phase
Carry out data transmission on same SRS resource symbol, all the SRS signal of CoMP UE will be caused to be interfered.As shown in Figure 1, UE1
Serving cell with UE2 is respectively CELL1 and CELL2, and UE1 is CoMP UE, and the cooperation cell of CELL1 is CELL2.UE1 is sent
SRS signal can not only be received by CELL1, while can also be received by CELL2.At this point, the SRS signal for the UE1 that CELL2 is received
It can be by the strong jamming of the UE2 signals sent on identical running time-frequency resource.

Case and joint delivery plan.Wherein, combined dispatching scheme refers to by time, frequency and the space resources between cell
Coordinate, distribute mutually orthogonal resource for different UE, interfering with each other between cell is avoided, to improve cell edge UE's
Performance；Joint delivery plan refer to multiple cells on identical running time-frequency resource simultaneously to the same UE transmission datas, with enhancing
The intensity for the signal that UE is received promotes the matter of UE received signals by the superposition of the useful signal from multiple cells
It measures, interfering with each other between reduction cell, to improve the performance of cell edge UE.
But there are still certain drawbacks for the above two scheme of downlink CoMP technologies.For using under joint delivery plan
Row CoMP technologies, serving cell and cooperation cell send physical down link sharing channel (Physical to CoMP UE simultaneously
Downlink Shared Channel, PDSCH) before data, need to carry out beam forming processing, medium wave to PDSCH data
The calculating of beam figuration vector needs to believe based on ascending channel detecting reference signal (Sounding Reference Signal, SRS)
Road estimated information, therefore, the quality of SRS signal quality are affected to downlink CoMP performances.Due to 3GPP R10 versions and
Version before does not support downlink CoMP characteristics, and when according to non-standard realization downlink CoMP characteristics, CoMP UE receive SRS letters
Number ability can by cooperation cell UE send SRS signal or transmitting uplink data signal strong jamming, lead to CoMP UE
The SRS signal of reception is second-rate, to influence downlink CoMP performances.
The problem of being interfered for the SRS signal of CoMP UE, it is static that prior art is generally adopted as CoMP UE
The method for configuring SRS resource so that the SRS resource of CoMP UE is orthogonal with the non-SRS resource of CoMP UE.This is CoMP UE
The method of static configuration SRS resource will cause the available SRS resource of non-CoMP UE to substantially reduce, to influence the profit of SRS resource
With rate, and then influence the user capacity of SRS supports.
In conclusion the SRS signal of CoMP UE can not be avoided to be interfered by cooperation cell completely using the prior art
Problem, and the utilization rate of SRS resource is influenced, and then reduce the number of users that SRS resource can be supported, reduce systematicness
Energy.
