Embodiment
To combine the accompanying drawing in the embodiment of the invention below, the technical scheme in the embodiment of the invention is carried out clear, intactly description, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills are not making all other embodiment that obtained under the creative work prerequisite, all belong to the scope of the present invention's protection.
The embodiment of the invention one provides a kind of information processing method, as shown in Figure 1, comprising:
The wherein said sub-district configuration set information of mourning in silence can comprise: the mourn in silence size of group of sub-district.Optional, the said sub-district configuration set information of mourning in silence can also comprise that the base station need be to the configuration of mourning in silence of which sub-district.
For example, following four kinds of configurations can be done in the base station:
(1) do not do and mourn in silence; (2) 2 sub-districts (mourn in silence group size be 3) of mourning in silence; (3) 5 sub-districts (mourn in silence group size be 6) of mourning in silence; (4) 8 sub-districts (mourn in silence group size be 9) or the like of mourning in silence.
Wherein, the number of the sub-district that mourn in silence can confirm arbitrarily according to actual needs that the group size is mourned in silence in corresponding sub-district also can be along with variation, and wherein mourn in silence and organize size=sub-district number+1 of mourning in silence in the sub-district.
In concrete the application, the base station can use 2 bits that above-mentioned four kinds possible configurations are sent to the terminal through high-level signaling or broadcast signaling.For example, 00 expression is not done and is mourned in silence, and 01 representes to mourn in silence 2 sub-districts, and 10 represent to mourn in silence 5 sub-districts, and 11 represent to mourn in silence 8 sub-districts.Certainly, if configuration increases, the base station also can use more bits to send the above-mentioned sub-district configuration set information of mourning in silence through high-level signaling or broadcast signaling.
Step 12, said terminal obtain cell group identification number and channel state information reference signals CSI-RS mode packet information.
Wherein, said terminal can obtain said cell group identification number (Cell_Group_ID) through detecting auxiliary synchronization channel, is used to identify each cell set.
The base station is divided into one or more CSI-RS modal sets (Pattern Group) to all CSI-RS patterns (Patterns), the number of CSI-RS pattern and sub-district the big or small identical of group (Muting Group) of mourning in silence in each CSI-RS modal sets.Wherein, the number of CSI-RS pattern can be regarded the modal sets size as in each CSI-RS modal sets, mourns in silence and organize size (Muting_Group_Size) in CSI-RS modal sets size (Pattern_Group_Size)=sub-district.And about the CSI-RS mode packet information of base station, can write in the protocol stack at terminal, perhaps the terminal that is to say that terminal self can obtain CSI-RS mode packet information in case start just can be obtained from the system broadcast information that the base station issues.
Concrete, said terminal can obtain the number of CSI-RS pattern in the CSI-RS modal sets, then according to the number of CSI-RS pattern in the pattern sum of CSI-RS pattern and the said CSI-RS modal sets with said CSI-RS mode packet.
In this step, sub-district group identifier and the sub-district identifier (Cell_ID) in the group of sub-district in the group of mourning in silence of mourning in silence can be confirmed according to said cell group identification number, the sub-district configuration set information of mourning in silence in said terminal.
Wherein, the sub-district group identifier of mourning in silence is used to represent that certain sub-district belongs to which sub-district group of mourning in silence, and for example mourn in silence and organize 0,1,2...... in the sub-district.As, when group is mourned in silence during big or small M=6 in the sub-district, cell group identification number is that 0,1 cell set is formed the sub-district group of mourning in silence, the mourn in silence sub-district of group, this sub-district mourns in silence that to organize identifier be 0.
If the base station becomes M sub-district with the sub-district group size configure of mourning in silence, so the sub-district mourn in silence organize in the group of M sub-district identifier (Cell_ID) can calculate according to following mode:
Cell_ID＝(Cell_Group_ID_Start+j)*3+i；
Wherein, wherein, Cell_ID representes the sub-district identifier in the group of sub-district of mourning in silence in the group, and Cell_Group_ID_Start representes mourn in silence in the group minimum cell group identification number of sub-district; I=0,1,2; J=0 .., (M/3-1), Cell_Group_ID_Start=Cell_Group_ID-Cell_Group_ID% (M/3), M represent the sub-district number of sub-district in the group of mourning in silence, and M is 3 positive integer multiple.
For example, size configure becomes 3 sub-districts if group is mourned in silence in the sub-district, at this moment M=3.So, the Cell_ID of 3 sub-districts that mourns in silence in the group of sub-district is exactly: Cell_ID=Cell_Group_ID x 3+i; (i=0,1,2).
Again for example, size configure becomes 6 sub-districts if group is mourned in silence in the sub-district, at this moment M=6.So, the Cell_ID of 6 sub-districts that mourns in silence in the group of sub-district is exactly:
Cell_Group_ID_Start＝Cell_Group_ID-Cell_Group_ID％2；
Cell_ID＝(Cell_Group_ID_Start+j)x?3+i；(i＝0，1，2；j＝0，1)。
Again for example, size configure becomes 9 sub-districts if group is mourned in silence in the sub-district, at this moment M=9.So, the Cell_ID of 9 sub-districts that mourns in silence in the group of sub-district is exactly:
Cell_Group_ID_Start＝Cell_Group_ID-Cell_Group_ID％ 3；
Cell_ID＝(Cell_Group_ID_Start+j)x?3+i；(i＝0，1，2；j＝0，1，2)。
Then, sub-district the mourn in silence pattern recognition number of sub-district in the group of modal sets identifier and the sub-district of group of mourning in silence is confirmed according to said cell group identification number, said sub-district the mourn in silence identifier in the group of sub-district in the group of configuration set information and said sub-district of mourning in silence in said terminal.
Wherein, the sub-district mourn in silence the group modal sets identifier=(Cell_Group_ID_Start/ (M/3)) modCSI-RS modal sets always organize number;
The sub-district mourn in silence the pattern recognition number of sub-district in the group=(the mourn in silence pattern sum of modal sets identifier * M+ (Cell_Group_ID% (M/3)) x (M-3)+Cell_ID_within_Cell_Group) mod CSI-RS pattern of group of sub-district,
Wherein, Cell_Group_ID_Start representes mourn in silence in the group minimum cell group identification number of sub-district, and modal sets is always organized number=f, and (the pattern sum of CSI-RS pattern/M), function f () is the function that rounds up; M representes the sub-district number of sub-district in the group of mourning in silence; Cell_ID_within_Cell_Group representes the interior identifier of mourning in silence and organize interior sub-district in the sub-district of group.
Mourn in silence in the group in step 14, the sub-district under the Serving cell at terminal, the terminal is to the pairing Resource Unit RE of the CSI-RS pattern of other sub-district except that the Serving cell at the terminal processing of mourning in silence.
For a sub-district, in mourning in silence and organize in the sub-district at its place, except the employed CSI-RS pattern in this sub-district, other the pairing RE of CSI-RS pattern should be mourned in silence.And for the terminal, mourn in silence in the group in the sub-district under the Serving cell at terminal, to the pairing Resource Unit RE of the CSI-RS pattern of other sub-district except that the Serving cell at the terminal processing of mourning in silence.And the mourn in silence CSI-RS pattern of all sub-districts in the group of the sub-district at the sub-district place of its service is known at the terminal; Therefore; Its processing of the pairing Resource Unit RE of the CSI-RS pattern of other sub-district except that its Serving cell can being mourned in silence, and need not the base station CSI-RS pattern that it should be mourned in silence and handle through any signaling again.This advice method can be described as " implicit expression notice ".
Can find out by above embodiment; Can obtain the mourn in silence configuration of base station through the sub-district that the obtains configuration set information of mourning in silence to the sub-district; And then the cell group identification of obtaining according to self number and channel state information reference signals CSI-RS mode packet information can confirm the mourn in silence CSI-RS pattern of other sub-district of group of the sub-district at CSI-RS pattern and its place of the Serving cell at terminal, thereby to the pairing Resource Unit RE of the CSI-RS pattern of other sub-district except that the Serving cell at the terminal processing of mourning in silence.By on can find out, in the technical scheme of the embodiment of the invention, just can mourn in silence and handle and the CSI-RS pattern of definite sub-district through a signaling, therefore, utilize the technical scheme of the embodiment of the invention can save signaling consumption.
It can also be seen that by embodiment shown in Figure 1 a configuration of mourning in silence at all terminals in the same sub-district all is identical with the RE that mourns in silence, we are referred to as sub-district specific (Cell-specific) and mourn in silence.
In addition, in order to improve the utilance of system spectrum, as shown in Figure 2, the embodiment of the invention two also can comprise before step 11 on the basis of embodiment one:
Wherein, the base station can be to the communication resource in the system, for example time resource and frequency resource, and following configuration is done at the terminal: the communication resource is divided into the resource that need mourn in silence and the resource that need not to mourn in silence.For the resource that needs are mourned in silence, it is distributed to the terminal that need not do the channels of neighboring areas measurement use; For the resource that need not to mourn in silence, it is distributed to the terminal that need do the channels of neighboring areas measurement use.
For example, when system bandwidth is 10MHz, 10MHz bandwidth separated into two parts: 8MHz and 2MHz, wherein the running time-frequency resource on the 8MHz bandwidth is done the processing of mourning in silence, and this part bandwidth is given CoMP or heterogeneous network etc. and need be done the terminal that channels of neighboring areas measures and use; Running time-frequency resource on the 2MHz bandwidth is not done the processing of mourning in silence in addition, and this part bandwidth is given and need not be done the terminal that channels of neighboring areas measures and use, such as single cell mimo user etc.At this, this scheme is called the specific perhaps specific configuration of mourning in silence of resource in terminal.
So; On the basis of embodiment one; For above-mentioned steps 14; The terminal is when mourning in silence processing; When the terminal is in the time of need doing the communication resource of the processing of mourning in silence for terminal and its shared resource that need do the channels of neighboring areas measurement; Mourn in silence in the group in said sub-district under the Serving cell at terminal, to the pairing Resource Unit RE of the CSI-RS pattern of other sub-district except that the Serving cell at the terminal processing of mourning in silence.
Therefore; The technical scheme of the embodiment of the invention two is except having saved signaling consumption; Can also adjust flexibly to the ratio at the terminal that need do the channels of neighboring areas measurement and need do the band width configuration of mourning in silence; Thereby reduced the unnecessary operation of mourning in silence; Promptly reduced owing to the expense of mourning in silence and bringing, thereby improved system spectral efficiency.
As shown in Figure 3, the embodiment of the invention three also provides a kind of information indicating method, comprising:
The wherein said sub-district configuration set information of mourning in silence can comprise: the mourn in silence size of group of sub-district.Optional, the said sub-district configuration set information of mourning in silence can also comprise that the base station need be to the configuration of mourning in silence of which sub-district.But the sub-district mode described in the mode refer step 11 of configuration set of mourning in silence is carried out in said base station.
In this step, said base station can send to the terminal with the said sub-district configuration set information of mourning in silence through high-level signaling or broadcast signaling.
By on can find out; The base station is through the sub-district configuration set information processing of can indicating terminal mourning in silence of mourning in silence; And by the terminal according to said sub-district mourn in silence configuration set information, CSI-RS mode packet information and said cell group identification number; Confirm the mourn in silence CSI-RS pattern of sub-district in the group of sub-district under the Serving cell at terminal; Then mourn in silence in the group in the sub-district under the Serving cell at terminal, to the pairing Resource Unit RE of the CSI-RS pattern of other sub-district except that the Serving cell at the terminal processing of mourning in silence.By on can find out, but mourn in silence with regard to indicating terminal through a signaling and handle and the CSI-RS pattern of definite sub-district in the base station in the technical scheme of the embodiment of the invention, therefore, utilizes the technical scheme of the embodiment of the invention can save signaling consumption.
In order to improve the utilance of system spectrum, on the basis of embodiment shown in Figure 3, as shown in Figure 4, the method for the embodiment of the invention four also can comprise before step 31:
Classify to the communication resource and terminal in step 30, base station, and classification results is sent to said terminal.Said classification results comprises: the communication resource distribution that need do mourns in silence handles gives the terminal that does not need channels of neighboring areas to measure for the terminal that needs channels of neighboring areas to measure, the communication resource distribution that need not do the processing of mourning in silence.
The concrete sorting technique in base station can be with reference to the mode described in the step 10 in this step.
Below, in conjunction with Fig. 5 and Fig. 6, the base station is described, the terminal processing of how mourning in silence how to terminal indication mourn in silence processings, indication CSI-RS pattern.
With the sub-district mourn in silence the group size be that M=3 is an example, the embodiment of the invention five specifically comprises the steps:
Step 41, base station be the sub-district configuration set information of mourning in silence, as, the big or small M=3 of the group of can being mourned in silence in the sub-district sends to the terminal through high-level signaling or broadcast signaling.
Step 42, the group size is 3 owing to mourn in silence in the sub-district, so CSI-RS modal sets size also is 3.
As shown in Figure 5, suppose to have 12 kinds of CSI-RS patterns, so, per three kinds of CSI-RS patterns are formed one group, can obtain four groups of CSI-RS mode packet altogether, are respectively modal sets 0, modal sets 1, modal sets 2 and modal sets 3.
Step 43, terminal obtain said cell group identification Cell_Group_ID through detecting auxiliary synchronization channel.
The group size is 3 owing to mourn in silence in the sub-district, and sub-district group of mourning in silence is formed in the sub-district that has identical Cell_Group_ID so.Suppose that one has 18 sub-districts, wherein the sub-district 0,1, and 2 have identical cell group identification number; Sub-district 3,4,5 have identical cell group identification number; Sub-district 6,7,8 have identical cell group identification number; Sub-district 9,10,11 have identical cell group identification number; Sub-district 12,13,14 have identical cell group identification number; Sub-district 15,16,17 have identical cell group identification number.As described above, as shown in Figure 6, above-mentioned 18 sub-districts can be divided into the sub-district mourn in silence the group 0, the sub-district mourn in silence the group 1, the sub-district mourn in silence the group 2 ... the sub-district mourn in silence the group 6.Wherein, 0......6 represents the mourn in silence sub-district group identifier of mourning in silence of group of sub-district respectively.
According to the mode of identifier (Cell_ID) in the calculating group in the step 13, can calculate in group is mourned in silence in the sub-district that identifier is respectively 0,1,2 in the group of sub-district.
Step 44, according to the mode in the step 13, calculation plot the mourn in silence pattern recognition number of sub-district in the group of modal sets identifier and the sub-district of group of mourning in silence.
Since the sub-district mourn in silence the group size be 3, so the sub-district mourn in silence the group identifier be cell group identification Cell_Group_ID.According to the mode in the step 13, can calculate sub-district the mourn in silence pattern recognition number of sub-district in the group of modal sets identifier and the sub-district of group of mourning in silence.
For example can calculate the mourn in silence pattern recognition of group 0 interior three sub-districts 0,1, of sub-district and No. 2 be respectively 0,1,2.Also promptly, the CSI-RS pattern of three sub-districts in group 0 is mourned in silence in the sub-district is respectively a pattern 0, pattern 1 and pattern 2.
Step 45, as previously mentioned; Should mourn in silence mutually in all sub-districts of mourning in silence in organizing in same sub-district; And the terminal can calculate and has the mourn in silence CSI-RS pattern of other sub-district of group identifier of same cells; So, the terminal can accomplish mourn in silence the operation and do not need the base station to carry out extra signaling.Like this, the base station has just been accomplished the implicit expression notice and has been mourned in silence configuration to the terminal.
So, mourn in silence in the group in the sub-district under the Serving cell at terminal, the terminal processing of can mourning in silence to the pairing Resource Unit RE of CSI-RS pattern of other sub-district except that the sub-district of the service at terminal.
Through using said method, the base station can just can be accomplished the CSI-RS pattern and mourn in silence configuration under the situation of only notifying the terminal to mourn in silence configuration (step 41).And the configuration (step 41) of mourning in silence is known through signaling on the one hand in the terminal, detects cell group identification number (Cell_Group_ID) through auxiliary synchronization channel on the other hand.In conjunction with the information of this two aspect, the sub-district at CSI-RS pattern and the Serving cell of oneself place of the Serving cell of oneself the CSI-RS pattern of all other sub-districts of group of mourning in silence just can be known in the terminal, thereby accomplishes the processing of mourning in silence.Therefore, utilize the scheme of the embodiment of the invention can save signaling consumption.
