Description
Technical field
The present invention relates to communication technical field, particularly a kind of method, system and device of informing user terminal of multi-cell coordination transmitted information.
Background technology
ITU is that the performance of next generation mobile communication system IMT-Advanced has proposed very harsh requirement.The maximum system transmission bandwidth reaches 100MHz, and the peak rate of up-downgoing transfer of data will reach 500Mbps and 1Gbps respectively, and system's average spectral efficiency (ase) especially edge spectrum efficiency has been proposed very high demand.In order to satisfy the requirement of the new system of IMT-Advanced, 3GPP is in its mobile cellular communication of future generation system, namely proposed to adopt the multi-point cooperative transmission technology to improve the performance of system in advanced Long Term Evolution (LTE-Advanced) system.
The multi-point cooperative transmission technology is the cooperation between a plurality of transfer points of separating on the geographical position, and in general, a plurality of transfer points are network side access node apparatus of different districts.The multi-point cooperative transmission technical scheme mainly is divided into two classes: combined dispatching and unite transmission.Combined dispatching is the coordination by the time between the residential quarter, frequency and space resources, for different user terminal (UE) distributes mutually orthogonal resource, avoids interference each other.The interference of minizone is the principal element of restriction cell edge UE performance, so combined dispatching can reduce the interference of minizone, thereby improves the performance of cell edge UE.Fig. 1 is the combined dispatching schematic diagram.As shown in Figure 1, by the combined dispatching of 3 residential quarters, three UE that may the phase mutual interference have dispatched on mutually orthogonal resource and (have represented different resources with different arrow patterns), have effectively avoided the interference between the residential quarter.
UE receives the signal of a plurality of residential quarters simultaneously.If all Serving cells send identical data to UE, can promote the signal quality of UE reception from the useful signal stack of a plurality of residential quarters, thereby improve systematic function.
In the LTE system, UE estimates the network side access node apparatus to the channel information of UE according to the public guide frequency port of residential quarter, and calculate channel quality indication (CQI) information (CQI) and feed back to the network side access node apparatus, the index that may also have pre-coding matrix (PMI) and the number of data streams (RI) together fed back together with CQI.CQI feedback makes that the network side access node apparatus can be dispatched, resource is distributed and the operation such as MCS selection, has improved the availability of frequency spectrum.
In order to realize COMP, Serving cell need to be known the information such as descending CQI, the PMI of COMP cooperation cell set small area and RI.For this reason, Serving cell need to be used for reporting relevant parameter for UE configures COMP information.Serving cell uses the COMP information of RRC message arrangement UE.
Need to prove, Serving cell refers to the residential quarter into the current place of UE, and UE monitors the PDCCH channel from Serving cell; The set of COMP reporting subdistrict refers to that UE need to carry out the set of cells of the information reportings such as CQI, PMI and RI; The set of COMP cooperation cell refers to the set of cells that participates in cooperating, and UE can be according to the scheduling of Serving cell, uses any one or the resource of several residential quarters in the cooperation cell set to carry out data transmit-receive.The set of COMP cooperation cell is the subset of COMP reporting subdistrict set.
