Description

A kind of processing method of channel quality indication (CQI) information and equipment

Technical field

The present invention relates to wireless communication field, particularly a kind of processing method of channel quality indication (CQI) information and equipment.

Background technology

The brief introduction of multicast communication technology:

ITU (International Telecommunication Union, International Telecommunications Union) be that the performance of next generation mobile communication system IMT-A (International Mobile Telecommunications-Advanced, international mobile telecommunication optimization) 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 (3rd Generation Partnership Project, 3G (Third Generation) Moblie standardization body) is in its mobile cellular communication LTE-Advanced of system of future generation (upgrading of LTE system; LTE:Long Term Evolution, Long Term Evolution) proposed in to adopt the multi-point cooperative transmission technology to improve the performance of 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 base stations of different districts.The multi-point cooperative transmission technical scheme mainly is divided into two classes: combined dispatching and unite transmission.Fig. 1 is the combined dispatching schematic diagram, and as shown in the figure, combined dispatching is the coordination by the time between the residential quarter, frequency and space resources, for different UE (User Equipment, subscriber equipment) 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.As shown in Figure 1, by the combined dispatching of 3 residential quarters, three UE that may the phase mutual interference have dispatched on the mutually orthogonal resource and (have represented different resources with different line styles among the figure), have effectively avoided the interference between the residential quarter.

Fig. 2 as shown in the figure, only has a residential quarter different to UE transmission data from the combined dispatching scheme for uniting the transmission schematic diagram, has a plurality of residential quarters to send data to UE simultaneously in the associating delivery plan, to strengthen UE reception signal.As shown in Figure 2, three residential quarters send data to a UE on identical resource, and UE receives the signal of a plurality of residential quarters simultaneously.If all home cell 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 base station to the channel information of UE according to the public guide frequency port of residential quarter, and calculate CQI (Channel Quality Indicator, the channel quality indication) information feeds back to the base station, may also have PMI (index of pre-coding matrix) and RI (RankInformation, order information) together with what CQI together fed back.The CQI of UE feedback is divided into broadband CQI and subband CQI.Broadband CQI is the overall target of all frequency band upper signal channel quality of system, and subband is the least unit of LTE feedback CQI in frequency domain, the channel quality in one section frequency band range of subband CQI reflection.The CQI feedback has improved the availability of frequency spectrum so that the base station can be dispatched, resource is distributed and MCS (Modulation and Coding Scheme, modulation coding mode) selection waits operation.

In the associating delivery plan, more than one to the residential quarter of UE the transmission of data, so the CQI of UE feedback also should reflect the channel quality of other cooperation districts except the channel quality of the home cell that will reflect UE.For this reason, CQI feedback has 2 kinds of different modes: the one, feed back respectively the channel quality of each cooperation district; The 2nd, feed back a comprehensive channel quality information of all cooperation districts.The second feedback system can reflect the channel quality of uniting when sending accurately, its feedback bandwidth that takies is also less, therefore be a kind of more excellent scheme, but the deficiencies in the prior art are: if UE only feeds back a comprehensive CQI in each residential quarter that calculates based on public guide frequency, actual CQI when network terminal can not obtain transfer of data, it is inaccurate that this also will inevitably cause MCS to select, thereby affect systematic function.Therefore calculating comprehensive CQI also needs the information such as number of antennas, and can obtaining more accurately, CQI comprehensively measures.

Embodiment

Below in conjunction with accompanying drawing the specific embodiment of the present invention is described.

The inventor notices in the invention process: in the associating delivery plan, and more than one to the residential quarter of UE the transmission of data, so the CQI of UE feedback also should reflect the channel quality of other cooperation districts except the channel quality of the home cell that will reflect UE.For this reason, CQI feedback has 2 kinds of different modes: the one, feed back respectively the channel quality of each cooperation district; The 2nd, feed back a comprehensive channel quality information of all cooperation districts.The second feedback system can reflect the channel quality of uniting when sending accurately, and its feedback bandwidth that takies is also less, is a kind of more excellent scheme therefore.

Yet for the associating delivery plan that adopts the private port transmission, the data during actual data transfer through weighting, are not identical in signal to noise ratio and the signal to noise ratio that calculates based on public guide frequency of receiving terminal demodulation at transmitting terminal.Therefore, the channel quality information that estimates based on public guide frequency can only be used for scheduling, and actual MCS also need to select the CQI according to feedback to carry out certain correction.Under the network condition of reality, the physical antenna number of each cooperation district may be different, so that the figuration gain of each residential quarter is also different.In addition, each cooperation district also is different to the channel fading degree of depth of UE.At this moment, if UE only feeds back a comprehensive CQI in each residential quarter that calculates based on public guide frequency, the actual CQI when network terminal is difficult to obtain transfer of data, it is inaccurate that this can cause MCS to select, and affects systematic function.For addressing this problem, learn the parameter of each cooperation district of multi-point cooperative transmission necessity in the embodiment of the invention by the system information that reads each cooperation district machine home cell, make UE can obtain other parameters of the outer cooperation district of public guide frequency.

Fig. 3 is the processing method implementing procedure schematic diagram of channel quality indication (CQI) information, as shown in the figure, can comprise the steps: in carrying out the CQI processing procedure

Step 301, base station carry information in the system information of each Cell Broadcast CB, described information are used for determining channel quality indication (CQI) information for subscriber equipment;

Step 302, subscriber equipment obtain described information from the system information that receives.

After this, UE just can determine accurately CQI according to described information, and reporting base station.

In the current LTE system, UE can obtain by the mode of blind check the antenna port information of this residential quarter, for handoff procedure, because UE can not read the system information of Target cell before switching, need to obtain separately by switching command contour level control signal the antenna port information of Target cell, based on this dual mode, UE need not to obtain antenna port information from the system information of this residential quarter.But in the LTE-A system, owing to introduced the multi-point cooperative transmission technology, UE can unite the CQI of each cooperation district of measuring and reports, UE is except needs are known the antenna port information of each cooperation district, also need to obtain the corresponding figuration gain adjustment amount of physical antenna number or each residential quarter of each cooperation district, be used for auxiliary CQI and report, UE need obtain the information (such as the physical antenna number) of each cooperation district in therefore implementing.

In the enforcement, obtain, information that be used for to determine CQI can comprise one of following or its combination: the figuration gain adjustment amount of antenna port information, physical antenna number, residential quarter.In the implementation, can determine the various parameters that needs obtain from system information according to the needs of determining CQI, by the mode that discloses below, obviously can get access to and determine the required various parameters of CQI.To describe as an example of the physical antenna number example during the below implements, and make corresponding modify when selecting other parameter and get final product.

In the enforcement, when obtaining the information of each cooperation district, there will be two kinds of situations, in the system information of each residential quarter, increase the information such as this residential quarter physical antenna number, particular location can be to add independent IE in certain SIB, perhaps adds independent SIB in system information, that is:

1, carry information is come by adding IE among the existing SIB in system information in the base station, and certainly, this information is for determine the channel quality indication for subscriber equipment.

Fig. 4 is the SystemInformationBlockType1message schematic diagram, as shown in the figure, with the same SIB of some information commons, namely in original certain SIB, add independent IE, add the physical antenna information of number antennaNumber of this residential quarter such as expansion, among the figure this part is illustrated with the font of overstriking.

2, carry information is come by add SIB in system information in the base station, and this information is for determine the channel quality indication for subscriber equipment.

Fig. 5 is SystemInformationBlockTypeX message schematic diagram, X is the system information block type that increases newly in order to expression, as shown in the figure, this residential quarter is as the alternative cooperation district of UE under the adjacent cell, adjacent cell UE is made the necessary information of multicast communication form an independent SIB, UE for adjacent cell reads, and the physical antenna information of number antennaNumber such as comprising this residential quarter illustrates this part among the figure with the font of overstriking.

After this, UE reads its system information separately from each adjacent cell that can do to work in coordination with, and extracts the wherein information such as physical antenna number of each residential quarter, the associating CQI feedback of auxiliary UE.By the way, so that terminal can be for each residential quarter of uniting to self in the service cell set that sends data, know that this residential quarter is to the CQI value of terminal, and according to the information of this residential quarter of network side transmitted the CQI value of this residential quarter is revised, then determine the comprehensive CQI value of service cell set according to revised each CQI value, and should comprehensive CQI value send to network side, so that UE can feed back the CQI information of the channel quality of reflection UE institute's home cell and other cooperation districts.

In the implementation, in the enforcement, comprise in the information that sends take the base station that the physical antenna number describes as example, the scheme of then according to the physical antenna number of the Serving cell of network side transmitted the CQI value of this residential quarter being revised specifically can adopt following two kinds:

The second, corresponding relation according to the CQI value that sets in advance, physical antenna number and CQI value adjustment amount, determine the CQI value adjustment amount corresponding with the physical antenna number of this residential quarter of the CQI value of this Serving cell, network side transmitted, adjust the CQI value of this residential quarter according to this CQI value adjustment amount, will adjust the result as revised CQI value.The method of adjusting the CQI value of residential quarter according to CQI value adjustment amount can have multiple, for example, and with CQI value and the addition of CQI value adjustment amount of residential quarter, subtract each other, multiply each other etc.

The scheme of the CQI value of this residential quarter being revised according to the figuration gain adjustment amount of the Serving cell of network side transmitted also can have multiple, for example, with the figuration gain adjustment amount addition of this residential quarter of the CQI value of Serving cell and network side transmitted, with addition result as revised CQI value; Perhaps, the figuration gain adjustment amount of this residential quarter of the CQI value of this residential quarter and network side transmitted is multiplied each other, with multiplied result as revised CQI value.

The figuration gain adjustment amount that network side sends can be the preferred value that obtains by emulation or actual measurement, also can be the theoretical value by calculating.Concrete, determine to unite to terminal the mode of the service cell set that sends data if adopt the first, then can network side determines to unite the service cell set that sends data to terminal according to the time delay of the intensity of the pilot signal that receives and/or downlink synchronous signal after, send physical antenna number or the figuration gain adjustment amount of each Serving cell to terminal; Determine to unite to terminal the mode of the service cell set that sends data if adopt the second, then can be after terminal send to network side with the information of the service cell set determined, network side sends to terminal with physical antenna number or the figuration gain adjustment amount of each Serving cell.

Through after the above-mentioned processing, can determine according to revised each CQI value the comprehensive CQI value of service cell set, concrete scheme can have following two kinds:

The first, if the Serving cell of determining is broadband CQI value to the CQI value of terminal, then according to the comprehensive CQI value of the revised CQI value of each broadband CQI value being determined service cell set, concrete definite scheme can have multiple, for example, with revised each CQI value addition, addition result is defined as the comprehensive CQI value of Serving cell collection; Perhaps, calculate the mean value of revised each CQI value, result of calculation is defined as the comprehensive CQI value of service cell set.

The second if the Serving cell of determining comprises a plurality of subband CQI values to the CQI value of terminal, then divides into groups revised each CQI value, and the frequency band range of the CQI value correspondence that comprises in every group is identical;

And for each grouping: according to the comprehensive CQI value of the definite service cell set of all CQI values in this grouping.Concrete definite scheme can have multiple, for example, with all the CQI value additions in this grouping, addition result is defined as a comprehensive CQI value of service cell set; Perhaps, calculate the mean value of all CQI values in this grouping, result of calculation is defined as a comprehensive CQI value of service cell set.

After this, during CQI information after network side receives the above-mentioned processing of process of terminal feedback, just can carry out according to this CQI information the operations such as scheduling of resource, resource distribution, MCS selection, to improve the availability of frequency spectrum.
