Embodiment
For the purpose, technical scheme and the advantage that make the embodiment of the invention clearer, below in conjunction with the accompanying drawing in the embodiment of the invention, technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that obtains under the creative work prerequisite.
In existing LTE Release 10, CSI can feed back to eNodeB in periodic or acyclic mode.During the aperiodicity feedback, UE is by Physical Uplink Shared Channel (Physical UplinkShared Channel; PUSCH) feedback because the capacity of PUSCH channel is bigger, needs the CSI of the feedback feedback simultaneously of can putting together, this moment eNodeB can configuration UE only feed back among the RI/PTI/PMI/CQI part but not all.During periodic feedback, UE is by Physical Uplink Control Channel (PhysicalUplink Control Channel; PUCCH) feedback, because it is much smaller that PUCCH compares the PUSCH channel capacity, so RI/PTI/PMI/CQI can be fed back separately or by certain combination, and eNodeB is that UE arranges corresponding feedback cycle and feedback time biasing, UE judges whether current time satisfies feedback cycle and the feedback time biasing that arranges, if satisfy then feedback.For the periodic feedback CSI that uses PUCCH, LTE Release 10 has defined different PUCCH form (PUCCH Format), can feed back RI/PTI/PMI/CQI separately or by certain combination.
The flow chart of the CSI method of measurement that Fig. 1 provides for one embodiment of the invention.As shown in Figure 1, the executive agent of the CSI method of measurement of present embodiment is the base station.The CSI method of measurement of present embodiment specifically can comprise the steps:
100, reference signal (the CSI-Reference Signal of a plurality of channel condition informations of concentrating is measured in the base station to CSI; CSI-RS)) divide into groups, obtain at least one grouping;
CSI-RS is a kind of reference signal of definition among the LTE Release 10 in the present embodiment.
101, the base station sends the grouping information of at least one grouping to UE;
Grouping information of each grouping comprises the CSI-RS that comprises in the group character of grouping and the grouping in the present embodiment.
102, the indication information of the grouping information of first grouping of a CSI of base station reception UE feedback and correspondence.
CSI-RS in the present embodiment is that UE selects the grouping information of first grouping to carry out the CSI acquisition from the grouping information of at least one grouping of reception.
The CSI method of measurement of present embodiment, by adopting technique scheme, can measure a plurality of CSI-RS that concentrate to CSI and divide into groups, obtain at least one grouping, and select the grouping information of grouping to carry out CSI by UE and measure, obtain the CSI of this grouping and feed back to the base station.The embodiment of the invention adopts technique scheme, and the CSI-RS of needs can be divided in a grouping, and measure this grouping by UE, can only be that object is measured CSI with whole TP and overcome in the prior art.Adopt the technical scheme of the embodiment of the invention, can accurately get access to the CSI that needs, use very flexible.
Further alternatively, on the basis of above-mentioned technical scheme embodiment illustrated in fig. 1, can also comprise following enlargement technology, form expansion embodiment embodiment illustrated in fig. 1.
CSI-RS is identified jointly by the configuration identifier of CSI and the port-mark under the configuration identifier in this expansion embodiment.For example the configuration of a CSI and should the configuration under CSI reference signal of a port-mark.Wherein the port number that the precoding codebook in the number of the port of the antenna of antenna correspondence and the existing system is supported in the embodiment of the invention is consistent, for example can be 1,2,4 or 8.
The CSI-RS that can make each grouping comprise when for example dividing into groups belongs to same CSI-RS configuration, and the sign of this each grouping is unique corresponding with the sequence number that sign such as the CSI-RS of a CSI-RS configuration dispose like this.But need to prove, this kind packet mode is for UE, and it is measured with the CSI-RS that feeds back and has been configured on the TP that is in same site in need not to distinguish, still on the TP of a plurality of different sites, be under a kind of distributing antenna system scene, the transparent CSI of UE measured the mode of feedback.
The structural representation of a kind of packet mode that Fig. 2 provides for the embodiment of the invention.As shown in Figure 2, in the present embodiment, base station (eNodeB) disposed 2 CSI-RS configurations for the CSI of UE appointment measures 3 TP that collection surrounds for solid line, CSI-RS configuration 0 has 4 antenna ports, and corresponding CSI-RS is respectively AP0,0, AP0,1, AP0,2 and AP0,3; CSI-RS configuration 1 has 8 antenna ports, and corresponding CSI-RS is respectively AP1,0, AP1,2, AP1,3, AP1,4, AP1,5, AP1,6 and AP1,7.What frame of broken lines was surrounded is different groupings.
Wherein divide into groups to have comprised in 01 CSI-RS configuration, be configured in 2 TP and gone up as on TP0 and the TP1, embodied the CSI-RS that belongs to different TP and can belong to same grouping.
4 ports in the grouping 1 in the CSI-RS configuration 1 are respectively as 2 groupings, for divide into groups 1 with grouping 2, embodied the CSI-RS reference signal that belongs to same TP and can belong to different grouping.
Further alternatively, in above-mentioned expansion embodiment embodiment illustrated in fig. 1, " base station sends the grouping information of at least one grouping to UE " in the step 101 specifically can comprise: the base station sends the grouping information of at least one grouping to UE by high-level signaling.
Further alternatively, in above-mentioned expansion embodiment embodiment illustrated in fig. 1, in the step 100 " dividing into groups to a plurality of CSI-RS that CSI measure to concentrate in the base station; obtains at least one grouping; specifically can comprise: according to making the received power difference of each CSI-RS in each grouping at least one grouping less than the packet mode of predetermined threshold value, CSI is measured a plurality of CSI-0RS that concentrate divide into groups;
Perhaps can comprise:, CSI is measured a plurality of CSI-RS that concentrate divide into groups less than the packet mode of predeterminable range threshold value according to the distance in the geographical position of the antenna of each CSI-RS correspondence in each grouping that makes at least one grouping.
Need to prove that the indication information of the grouping information of first grouping comprises the CSI-RS that comprises in first group character of dividing into groups and/or first grouping in this expansion embodiment.Preferably, the indication information of the grouping information of this first grouping is the group character of first grouping.
Particularly can comprise following several situation for above-mentioned step 102 " base station receives the indication information of the grouping information of a CSI of UE feedback and corresponding first grouping " in embodiment illustrated in fig. 1 this moment:
First kind of situation is that the base station receives a CSI of UE feedback and the first corresponding grouping information of dividing into groups, the base station just can get access to grouping information and a CSI of this first grouping like this, determines simultaneously that also a CSI is that UE measures based on this first grouping information of dividing into groups; But this scheme causes signaling consumption bigger owing to will feed back among the CSI and the grouping information of the first corresponding grouping.
Second kind of situation is that the base station receives the CSI-RS that comprises in a CSI of UE feedback and corresponding first grouping, the base station just can get access to CSI-RS and a CSI who comprises in this first grouping like this, determines simultaneously that also a CSI is that UE measures based on the CSI-RS that comprises in this first grouping; But this scheme is owing to the CSI-RS that comprises in first grouping that will feed back a CSI and correspondence, and with respect to above-mentioned first kind of situation, feedback content is less, can relax signaling consumption.
The third situation is preferred version, in the third situation, the base station receives a CSI of UE feedback and the first corresponding group character of dividing into groups, the base station just can get access to group character and a CSI of this first grouping like this, determines simultaneously that also a CSI is that UE obtains based on this first grouping mea-sure; But this scheme only needs to feed back a CSI and the first corresponding group character of dividing into groups, and with respect to above-mentioned first kind of situation and second kind of situation, feedback content is less, can reduce signaling consumption effectively, improves efficiency of transmission.
Further alternatively, in this expansion embodiment, in the grouping information of at least one grouping, comprise the grouping information of a plurality of groupings; When selecting the grouping information of at least two first groupings to carry out CSI respectively from the grouping information of a plurality of groupings, measures UE, when obtaining at least two CSI; Corresponding step 102 this moment " base station receives the indication information of the grouping information of a CSI of UE feedback and corresponding first grouping " is specifically as follows: the base station receives at least two CSI of UE by PUSCH aperiodicity feedback and the indication information of the grouping informations of corresponding at least two first groupings; Perhaps the base station receives at least two CSI of UE by the PUCCH periodic feedback and the indication information of the grouping informations of corresponding at least two first groupings.In like manner the indication information of the grouping information of first grouping wherein can be the CSI-RS that comprises in first group character of dividing into groups and/or first grouping.Preferably, the indication information of the grouping information of this first grouping is the group character of first grouping.
Further alternatively, when at least two CSI be that UE adopts that relevant associating send mode sends or adopts incoherent associating send mode transmission; And at least two CSI are that UE adopts relevant associating send mode to send, in this expansion embodiment, above-described embodiment " base station receives at least two CSI of UE by PUSCH aperiodicity feedback and the indication information of the grouping informations of corresponding at least two first groupings; Perhaps the base station receives at least two CSI of UE by the PUCCH periodic feedback and the indication information of the grouping informations of corresponding at least two first groupings " afterwards; can also comprise: the base station receive among at least two CSI that UE sends arbitrarily between the two between phase information and/or amplitude information; so that when receiving at least two CSI, the base station can accurately receive each CSI.For example shown in Figure 2 is among the embodiment, if the reporting CSI to concentrate to have comprised simultaneously of UE divides into groups 0 and the CSI of grouping 1, and need relevant associating transmission, phase place and/or amplitude information between the CSI that then needs additional feedback grouping 0 and 1 the CSI of dividing into groups, relation between two groupings is described, so that UE accurately obtains the CSI of each grouping.
The CSI method of measurement of above-described embodiment, by adopting technique scheme, can measure a plurality of CSI-RS that concentrate to CSI and divide into groups, obtain at least one grouping, and select the grouping information of grouping to carry out CSI by UE and measure, obtain the CSI of this grouping and feed back to the base station.The embodiment of the invention adopts technique scheme, and the CSI-RS of needs can be divided in a grouping, and measure this grouping by UE, can only be that object is measured CSI with whole TP and overcome in the prior art.Adopt the technical scheme of the embodiment of the invention, can accurately get access to the CSI that needs, use very flexible.

The CSI method of measurement of present embodiment and above-mentioned difference embodiment illustrated in fig. 1 only are: above-mentionedly embodiment illustrated in fig. 1ly describe technical scheme of the present invention in base station side; And present embodiment is described technical scheme of the present invention in the UE side.Can not repeat them here with reference to above-mentioned record embodiment illustrated in fig. 1 in detail.
The CSI method of measurement of present embodiment, by adopting technique scheme, can measure a plurality of CSI-RS that concentrate to CSI and divide into groups, obtain at least one grouping, and select the grouping information of grouping to carry out CSI by UE and measure, obtain the CSI of this grouping and feed back to the base station.The embodiment of the invention adopts technique scheme, and the CSI-RS of needs can be divided in a grouping, and measure this grouping by UE, can only be that object is measured CSI with whole TP and overcome in the prior art.Adopt the technical scheme of the embodiment of the invention, can accurately get access to the CSI that needs, use very flexible.
Alternatively, on the basis of above-mentioned technical scheme embodiment illustrated in fig. 3, specifically can also comprise following enlargement technology, form expansion embodiment embodiment illustrated in fig. 3.In expansion embodiment embodiment illustrated in fig. 2, the CSI-RS in the present embodiment is identified jointly by the configuration identifier of CSI and the port-mark under the configuration identifier.
Alternatively, in expansion embodiment embodiment illustrated in fig. 3, in the step 200 " UE receives the grouping information of at least one grouping of base station transmission ", comprising: UE receives the base station by the grouping information of at least one grouping of high-level signaling transmission.
Alternatively, in expansion embodiment embodiment illustrated in fig. 3, in the step 200 UE receive at least one grouping that the base station sends grouping information at least one be grouped into: a plurality of CSI-RS of concentrating are measured according to making the received power difference of each CSI-RS in each grouping at least one grouping less than the packet mode of predetermined threshold value in the base station to CSI-RS, CSI is measured a plurality of CSI-RS of concentrating divide into groups to obtain;
Perhaps in the step 200 UE receive at least one grouping that the base station sends grouping information at least one be grouped into: a plurality of CSI-RS of concentrating are measured according to the distance in the geographical position of the antenna of each CSI-RS correspondence in each grouping that makes at least one grouping packet mode less than the predeterminable range threshold value in the base station to CSI, CSI is measured a plurality of CSI-RS of concentrating divide into groups to obtain.
Alternatively, the indication information of the grouping information of first grouping in expansion embodiment embodiment illustrated in fig. 3 comprises the CSI-RS that comprises in first group character of dividing into groups and/or first grouping.Preferably, the indication information of the grouping information of this first grouping is the group character of first grouping.
Alternatively, at expansion embodiment embodiment illustrated in fig. 3, " from the grouping information of at least one grouping, select the grouping information of first grouping to carry out the CSI measurement; to obtain a CSI " in the step 201, comprise: when comprising the grouping information of a plurality of groupings in the grouping information of at least one grouping, from the grouping information of a plurality of groupings, select the grouping information of at least two first groupings to carry out the CSI measurement respectively, obtain at least two corresponding CSI.
This moment accordingly, above-mentioned step 202 embodiment illustrated in fig. 3 " UE is to the indication information of the grouping information of first grouping of base station feedback the one CSI and correspondence ", specifically can comprise: UE is to the indication information of the grouping information of at least two first groupings of at least two CSI of base station feedback and correspondence.

The difference of expansion embodiment embodiment illustrated in fig. 3 and above-mentioned expansion embodiment embodiment illustrated in fig. 1 only is: above-mentioned expansion embodiment embodiment illustrated in fig. 1 describes technical scheme of the present invention in base station side; And expansion embodiment embodiment illustrated in fig. 3 describes technical scheme of the present invention in the UE side.Can not repeat them here with reference to above-mentioned record embodiment illustrated in fig. 1 in detail.
The CSI method of measurement of above-described embodiment, by adopting technique scheme, can measure a plurality of CSI-RS that concentrate to CSI and divide into groups, obtain at least one grouping, and select the grouping information of grouping to carry out CSI by UE and measure, obtain the CSI of this grouping and feed back to the base station.The embodiment of the invention adopts technique scheme, and the CSI-RS of needs can be divided in a grouping, and measure this grouping by UE, can only be that object is measured CSI with whole TP and overcome in the prior art.Adopt the technical scheme of the embodiment of the invention, can accurately get access to the CSI that needs, use very flexible.
Alternatively, in above-mentioned expansion embodiment embodiment illustrated in fig. 3, the indication information that UE carries the grouping information of the first corresponding grouping during to base station feedback CSI is preferably the group character of this first grouping, and this group character also can become packet index.This moment, corresponding feedback can become implicit feedback.
Based on above-mentioned packet-based CSI feedback scheme, introduce two kinds of scenes of planting above-mentioned CSI feedback in addition below.
In first scene, when CSI was specially RI, UE passed through PUCCH periodically to base station feedback RI,
UE is when passing through PUCCH periodically to base station feedback RI, in the present embodiment, packet-based CSI feedback scheme is used for periodic feedback RI, and packet index not the situation by implicit feedback, be that UE feeds back extra amount in addition, measure and feedback to support packet-based CSI.
Because RI is the broadband, namely the value of a RI can characterize the whole subbands on the frequency band.If owing to use the SU-MIMO pattern to send data to UE among the LTE, then Dui Ying RI value is probably greater than 2.But if when using CoMP transmission plan such as DPS, JT when UE sends data, the value that then can limit RI is 1 or 2.Because eNodeB is when scheduling, not every UE uses the CoMP transmission plan, so always need UE feedback RI.
After introducing grouping, on existing PUCCH form basis, need extra several PUCCH forms that increase: 1) independent packet index feeds back, increase PUCCH Format 7, the feedback cycle that packet index can be set is identical with RI, and feedback time biasing is set in advance the feedback time of RI several TTI that setover.2) packet index feeds back with existing RI, first PMI, PTI, increases PUCCHFormat 3a/5a/6a respectively, and the PUCCH Format 3/5/6 with original is identical respectively with the feedback time biasing for feedback cycle.Newly-increased PUCCH form and original PUCCH form, as shown in table 1 below.
Table 1
The PUCCH form The content of feedback
3 RI
3a The RI/ packet index
5 RI/first PMI
5a RI/first PMI/ packet index
6 RI/PTI
6a The RI/PTI/ packet index
