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 has promptly proposed in Xian Jin Long Term Evolution (LTE-Advanced) system to adopt the multi-point cooperative transmission technology to improve the performance of system in its mobile cellular communication of future generation system.
The multi-point cooperative transmission technology is the cooperation between a plurality of transmission points that separate on the geographical position, and in general, a plurality of transmission 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 sub-district, frequency and space resources, for the resource that different user terminal (UE) distributes mutually orthogonal, 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 sub-districts, three UE that may the phase mutual interference have dispatched on the mutually orthogonal resource and (have represented different resources with different arrow patterns), have effectively avoided the interference between the sub-district.
Fig. 2 is for uniting the transmission schematic diagram.Referring to shown in Figure 2, have only a sub-district different with the combined dispatching scheme to UE transmission data, there are a plurality of sub-districts to send data to UE simultaneously in the associating delivery plan, to strengthen the UE received signal.As shown in Figure 2, three sub-districts send data to a UE on identical resource, and UE receives the signal of a plurality of sub-districts 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 sub-districts, thereby improve systematic function.
In the LTE system, UE estimates the channel information of network side access node apparatus to UE according to the public guide frequency port of sub-district, and calculate channel quality indication (CQI) information (CQI) and feed back to the network side access node apparatus, index that may also have pre-coding matrix (PMI) and the number of data streams (RI) together fed back together with CQI.Operations such as CQI feedback makes that the network side access node apparatus can be dispatched, resource allocation and MCS selection have improved the availability of frequency spectrum.
In order to realize COMP, Serving cell need be known information such as descending CQI, the PMI of sub-district in the set of COMP cooperation cell and RI.For this reason, Serving cell need be used to report relevant parameter for UE disposes COMP information.Serving cell uses the COMP information of RRC message arrangement UE.
Need to prove that Serving cell is meant the sub-district into the current place of UE, UE monitors the PDCCH channel from Serving cell; The set of COMP reporting subdistrict is meant that UE need carry out the set of cells that information such as CQI, PMI and RI report; The set of COMP cooperation cell is meant the set of cells that participates in cooperation, and UE can be according to the scheduling of Serving cell, and any one in the set of use cooperation cell or the resource of several sub-districts are carried out data transmit-receive.The set of COMP cooperation cell is the subclass of COMP reporting subdistrict set.
