Description
Technical field
The present invention relates to communication technical field, be meant a kind of method and device that reports, obtains many sub-districts received power and resource distribution especially.
Background technology
International Telecommunications Union (ITU, International Telecommunications Union) has proposed very harsh requirement for the performance of next generation mobile communication system IMT-Advanced.Reach 100MHz such as the maximum system transmission bandwidth, the peak rate of up-downgoing transfer of data need reach 1Gbps and 500M bps, 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, 3-G (Generation Three mobile communication system) (3GPP) has proposed to adopt the multi-point cooperative transmission technology to improve the performance of system in its mobile cellular communication advanced person's of system of future generation Long Term Evolution (LTE-Advanced).The multi-point cooperative transmission technology is the cooperation between a plurality of transmission points that separate on the geographical position.In general, a plurality of transmission points are base stations of different districts.The collaborative transmission that the multi-point cooperative transmission technical point is descending and up unite reception.Descending 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 terminal (UE) is distributed 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.As shown in Figure 1, by the combined dispatching of 3 sub-districts, three UE that may the phase mutual interference have dispatched (with the different resource of different color showings) on the mutually orthogonal resource, have effectively avoided the interference between the sub-district.
Have only a sub-district different with the combined dispatching scheme, have a plurality of sub-districts to send data to UE simultaneously in the associating delivery plan, to strengthen the UE received signal to UE transmission data.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.On the one hand, stack can promote the signal quality that UE receives from the useful signal of a plurality of sub-districts, on the other hand, has reduced the interference that UE is subjected to, thereby improves systematic function.
Up unite to receive be meant that a plurality of sub-districts receive the data that a UE sends simultaneously, the data that each sub-district receives are carried out Combined Treatment to improve the demodulation quality of UE data.Up scheme of uniting reception as shown in Figure 3.
In the LTE system, UE estimates the channel information of base station to UE according to the public guide frequency port of sub-district, and calculate channel quality indication (CQI) information (CQI) and feed back to index that may also have pre-coding matrix (PMI) and the number of data streams (RI) that base station and CQI together feed back.Operations such as CQI feedback makes that the base station can be dispatched, resource allocation and MCS selections, the raising availability of frequency spectrum.The LTE-A system has further strengthened reporting of channel information for supporting multi-point cooperative transmission.UE estimates the channel information of each sub-district to UE according to the public guide frequency of measuring set of cells (MeasurementSet) interior sub-district transmission.Subsequently, UE feeds back to the base station after directly channel information being quantized.Pre-coding matrix calculating is carried out according to the channel information of UE feedback in the base station, multi-user's pairing, operations such as MCS selection.For the TDD system, the base station can obtain uplink channel information according to the SRS signal that UE sends, and the reciprocity of property channel obtains descending channel information about utilizing.Yet only according to the channel information of UE feedback or the channel information that obtains by SRS, code modulation mode (MCS can accurately not selected for UE in the base station, Modulation and Coding Scheme) and carry out frequency domain dispatching, because the interference that uplink downlink is subjected to generally is different.
In sum, the mechanism that does not also have many sub-districts received power to report in the prior art, and because the interference that uplink downlink is subjected to generally is different, base station side is that some resource distribution of terminal may be inaccurate, unreasonable.
