Description
Technical field
The present invention relates to the communications field, relate in particular to a kind of detection reference signal SRS resource allocation methods and device.
Background technology
At Long Term Evolution (Long Term Evolution, LTE) in system, downlink data transmission and transfer of data are up all to be adopted based on OFDM (Orthogonal Frequency Division Multiplex, OFDM) quadrature multi-access mode, now, in realizing the process of identical networking, Serving cell receives its subscriber equipment (User Equipment, the ability of the signal UE) sending, or the ability that UE receives the signal that its Serving cell sends can be subject to the interference of cooperation cell, for reducing this phase mutual interference between community, 3GPP introduces coordinated multipoint transmission (Coordinated Multiple Points in R11 version, CoMP) technology.
In descending CoMP, the SRS signal that CoMP UE sends is simultaneously received in Serving cell and cooperation cell, due to the SRS resource of CoMP UE and the SRS resource of cooperation cell UE generally non-orthogonal, or cooperation cell UE carries out transfer of data with CoMP UE on identical SRS resource symbol, all will cause the SRS signal of CoMP UE to be interfered.As shown in Figure 1, the Serving cell of UE1 and UE2 is respectively CELL1 and CELL2, and UE1 is CoMP UE, and the cooperation cell of CELL1 is CELL2.The SRS signal that UE1 sends not only can be received by CELL1, also can be received by CELL2 simultaneously.Now, the SRS signal of the UE1 that CELL2 receives can be subject to the strong jamming of the signal that UE2 sends on identical running time-frequency resource.
CoMP technology comprises up CoMP technology and descending CoMP technology; Descending CoMP technical scheme comprises combined dispatching scheme and associating delivery plan.Wherein, combined dispatching scheme refers to by the coordination of the time between community, frequency and space resources, for different UE distributes mutually orthogonal resource, avoids the phase mutual interference between community, thereby improves the performance of cell edge UE; Associating delivery plan refers to that a plurality of communities send data to same UE on identical running time-frequency resource simultaneously, the intensity of the signal receiving with enhancing UE, by the stack of the useful signal from a plurality of communities, promote the quality of the signal of UE reception, reduce the phase mutual interference between community, thereby improve the performance of cell edge UE.
But still there is certain drawback in the above-mentioned two schemes of descending CoMP technology.For the descending CoMP technology that adopts associating delivery plan, Serving cell and cooperation cell send physical down link sharing channel (Physical Downlink Shared Channel to CoMP UE simultaneously, PDSCH) before data, need to carry out beam forming processing to PDSCH data, wherein the calculating of wave beam forming vector need to be based on ascending channel detecting reference signal (Sounding Reference Signal, SRS) channel estimating information, therefore, the quality of SRS signal quality is larger to descending CoMP performance impact.Because 3GPP R10 version and version before are not supported descending CoMP characteristic, according to non-standard while realizing descending CoMP characteristic, the ability that CoMP UE receives SRS signal can be subject to the SRS signal of UE transmission in cooperation cell or the strong jamming of transmitting uplink data signal, the SRS signal quality that causes CoMP UE to receive is poor, thereby affects descending CoMP performance.
The problem being interfered for the SRS signal of CoMP UE, prior art scheme is generally adopted as the method for CoMP UE static configuration SRS resource, makes the SRS resource of CoMP UE and the SRS resource quadrature of non-CoMP UE.This for the method for CoMP UE static configuration SRS resource will cause the available SRS resource of non-CoMP UE significantly to reduce, thus the utilance of SRS resource affected, and then have influence on the user capacity that SRS supports.
In sum, adopt prior art can not avoid the SRS signal of CoMP UE to be subject to the problem that disturb cooperation cell completely, and affect the utilance of SRS resource, and then reduced the number of users that SRS resource can be supported, reduce systematic function.
