Embodiment bis-
The present embodiment provides a kind of method of notification reference signal configuration information, because CSI-RS has, expense is little, the cycle long, the multiplexing factor is high, the feature of the nested low port pilot frequency design of high port pilot frequency design, therefore, the present embodiment is by encoding to CSI-RS configuration information, and with the form of CSI-RS configuration information coding, CSI-RS configuration information is notified to UE, make UE determine CSI-RS configuration information, thereby reach minimizing expense, the object that the CSI-RS of assurance Geng Duo community does not collide mutually.
Wherein, the equipment of notification reference signal configuration information is the network equipment, and CSI-RS configuration information comprises but is not limited to port number, pilot frequency design, pilot period and subframe skew.
If the data symbol that the CSI-RS of certain community and strong jamming community send collides mutually, the network equipment may be required on the position of the CSI-RS sending out this community, and strong jamming community is all done data quiet (muting) and processed, and avoids the interference to reference signal.Now this community need to be notified CSI-RS pilot frequency locations (comprising pilot period and pilot frequency design etc.) to each strong jamming community.In addition, the network equipment also needs quiet the data of CSI-RS position informing to UE, makes UE supposition in this position, there is no the transmission of data symbol, and receiver does not carry out Data Detection in this position, and UE estimates the down channel of respective cell on this position.For the situation of this kind of network equipment supported data quietness technology, CSI-RS configuration information, except comprising port number, pilot frequency design, pilot period and subframe skew, also comprises the quiet position of data.
If the network equipment is on the quiet basis of supported data, also support sector's divided data is quiet, the network equipment also needs data mute periods and the quiet skew of data to notify to UE, for this kind of situation, CSI-RS configuration information, except comprising port number, pilot frequency design, pilot period, subframe skew and the quiet position of data, also comprises the quiet skew of data mute periods and data.
Below, the present embodiment is with the network equipment both supported data quietness technology, and support sector's divided data quietness technology is example again, and the method that the present embodiment is provided is elaborated.Now, CSI-RS configuration information had both comprised port number, pilot frequency design, pilot period, subframe skew and the quiet position of data, also comprised the quiet skew of data mute periods and data, and referring to Fig. 2, the method flow that the present embodiment provides is specific as follows:
201: the network equipment carries out associated coding by port number and pilot frequency design, obtains the first coding result;
Wherein, CSI-RS port number has 2,4,8 three kind may, the port number that pilot frequency design is corresponding different and different sub-frame configuration have following several may, as shown in table 1:
Table 1
| CSI-RS |
2 | 4 | 8 |
| Common CP can be used CSI-RS pilot frequency design number | 20 | 10 | 5 |
| Common CP w/o CRS ports2/3 can use CSI-RS pilot frequency design number | 32 | 16 | 8 |
| Expansion CP can use CSI-RS pilot frequency design number | 16 | 8 | 4 |
| Expansion CP w/o CRS ports2/3 can use CSI-RS pilot frequency design number | 28 | 14 | 7 |
As shown in table 1, the corresponding different port number of pilot frequency design has at most respectively 32(2 port), 16(4 port), 8(8 port) planting may.In general, port number and pilot frequency design have at most 32+16+8=56 kind possibility.While port number being carried out to associated coding with pilot frequency design, can adopt any one mode in following two kinds of modes to realize:
First kind of way: port number and pilot frequency design are carried out to combined coding with 6 bits.
This 6 bit signalling can be indicated 64 kinds of states, can use wherein any 56 kinds of states, and they are corresponding one by one with pilot frequency design combination with 56 kinds of port numbers, sets up a mapping table.Therefore, UE, by receiving this 6 bit signalling and searching mapping table, can learn port number and the pilot frequency design of CSI-RS.
Particularly, consider that port number is respectively at 2,4,8 o'clock, the pilot frequency design of CSI-RS has nested characteristic, be that each 8 port pilot frequency designs can nested two 4 port pilot frequency designs, nested two the 2 port pilot frequency designs of each 4 port pilot frequency designs, if two parts before and after 8 port pilot frequency designs are divided into, each part is 4 port pilot frequency designs; If two parts before and after 4 port pilot frequency designs are divided into, each part is 2 port pilot frequency designs.Based on this Nested property, can determine by two steps below the mapping relations of port number and pilot frequency design:
The first step: 3 bits of lowest order and 8 kinds of pilot frequency designs of 8 ports are set up corresponding relation, and the present embodiment does not specifically limit the corresponding relation of 3 of lowest order bits and 8 port pilot frequency designs, only take the corresponding relation shown in table 2 below as example:
Table 2
| 8 port pilot frequency designs | Coding |
| The first 8 port pilot frequency designs | 000 |
| The second 8 port pilot frequency designs | 001 |
| The third 8 port pilot frequency design | 010 |
| The 4th kind of 8 port pilot frequency design | 011 |
| The 5th kind of 8 port pilot frequency design | 100 |
| The 6th kind of 8 port |
101 |
| The 7th kind of 8 port pilot frequency design | 110 |
| The 8th kind of 8 port pilot frequency design | 111 |
When port number is 2 or 4,3 bits of this lowest order represent 8 port pilot frequency designs that can nested indicated pilot frequency design.The numbering of the 8 port pilot frequency designs that mapping table is corresponding as shown in Figures 3 to 6.
Second step: when port number is 8,3 bits of highest order are 110;
When port number is 4,2 bits of highest order are that 10, the 3 bits indicate 4 port pilot frequency designs by the position in 8 nested port pilot frequency designs, and 0 represents first half, and 1 represents latter half;
When port number is 2,1 bit of highest order is 0; The 2nd bit indicates 2 port pilot frequency designs by the position in 4 nested port pilot frequency designs, and 0 represents first half, and 1 represents latter half;
If there is no CSI-RS, can represent with " 111111 ", concrete mapping relations are as shown in table 3 below:
Table 3
Wherein, the corresponding relation that x representative in table 3 in 3 of lowest order bits and 8 kinds of pilot frequency designs of 8 ports are set up, take the result of port number and pilot frequency design combined coding as 100101 as example, because 3 bits of the highest order in this coding result are 100, as can be seen from Table 3, the port number that this coding result is corresponding is 4 ports, and this 4 port is 8 port pattern first halfs.In addition, because 3 bits of the lowest order in this coding result are 101, from above-mentioned table 2, can find out, be the 5th kind of 8 port pilot frequency design.
The second way: port number and pilot frequency design are encoded respectively.
During specific implementation, the CRC(Cyclic Redundancy Check by port number scrambled to x SIB, cyclic redundancy check (CRC) code) upper, pilot frequency design is indicated by the signaling of 5 bits.
Wherein, x system information block is the system information block for configuring CSI-RS information.Based on the Nested property of CSI-RS, can obtain the signaling of 5 bits and the mapping relations of pilot frequency design by following two steps:
The first step: 3 bits of lowest order and 8 kinds of pilot frequency designs of 8 ports are set up relation one to one, when port number is 2 or 4, these three bits represent 8 port pilot frequency designs that can nested indicated pilot frequency design.
Second step: when port number is 8,2 bits of highest order are the arbitrary value in 0 and 1;
When port number is 4,1 bit of highest order is the arbitrary value in 0 and 1, and the 2nd bit indicates 4 port pilot frequency designs by the position in 8 nested port pilot frequency designs, and 0 represents first half, and 1 represents latter half;
When port number is 2, the 1st bit indicates 2 port pilot frequency designs by the position in 4 nested port pilot frequency designs, and 0 represents first half, and 1 represents latter half.
In the present embodiment, pilot frequency design can be divided into different pilot frequency design groups according to first half and latter half.Take 2 port pilot frequency designs as example, it can be divided into 2 pilot frequency design groups according to 4 port pilot frequency design first halfs and latter half, now, the 2nd bit in above-mentioned first kind of way of port number and pilot frequency design being carried out to associated coding and the 1st bit in the second way can be indicated affiliated pilot frequency design group.
Further, according to 8 port pilot frequency design first halfs and latter half, above-mentioned 2 pilot frequency design groups are further divided into 4 pilot frequency design groups, now the 1st and the 2nd bit in the 2nd in first kind of way and the 3rd bit and the second way can be indicated affiliated pilot frequency design group.Take 4 port pilot frequency designs as example, it can be divided into 2 pilot frequency design groups according to 8 port pilot frequency design first halfs and latter half, and now the 2nd bit in the 3rd bit and the second way in first kind of way can be indicated affiliated pilot frequency design group.
It should be noted that, the first half of the alleged 8 port pilot frequency designs of the present embodiment, refer to 8 port pilot frequency designs according to being divided into two parts by its 4 nested port pilot frequency designs, wherein forward part, it can be the first half of 8 port pilot frequency design entirety, also can be the first half in every half 8 port pilot frequency design, pilot frequency design take label in Fig. 3 as 0 is as example, total four lines from top to bottom, both front two row can be called to first half, also the first row in the first row in front two row and rear two row can be referred to as to first half, the present embodiment is not done concrete restriction to this, the first half implication of 4 port pilot frequency designs is with the first half implication of 8 port pilot frequency designs, the present embodiment is not done concrete restriction equally.No matter adopt above-mentioned which kind of mode to carry out associated coding to port number and pilot frequency design, the coding result obtaining is referred to as the first coding result, for clear and definite every kind of concrete port number and pilot frequency design that coding result is corresponding, the network equipment, after obtaining the first coding result, also needs to set up the corresponding relation of the first coding result and port number and pilot frequency design.
202: pilot period is carried out to associated coding with subframe skew, obtain the second coding result;
Wherein, the pilot period of CSI-RS is the multiple of 5 milliseconds, supposes that the CSI-RS cycle is 5N millisecond, and N is positive integer, and the value of N is by R10 regulation and stipulation, and each millisecond is corresponding to a subframe.Subframe skew referred under a certain CSI-RS cycle, and the subframe of carrying CSI-RS is with respect to the sub-frame offset of benchmark subframe (being first subframe in 5N subframe).Owing to having stipulated may to need to carry the information such as synchronizing channel, broadcast channel, paging channel in the 0th of every 5 subframes and the 4th subframe in R10 standard, so these subframes can not be carried CSI-RS, therefore the CSI-RS cycle of corresponding 5N ms, subframe skew has at most 3N kind possibility.
For the coding of the pilot period of CSI-RS and subframe skew, can adopt any in following two kinds of modes:
First kind of way: the pilot period of CSI-RS and subframe skew are encoded respectively.
Suppose that the value of N is for { 1,2,3,4,5,6,7,8} needs 3 bits to indicate the cycle of CSI-RS so.For subframe skew, when N=8, there are at most 24 kinds of possibilities, so need 5 bits indicate the subframe skew of CSI-RS.On the whole, need altogether 3+5=8 bit to indicate cycle and the subframe skew of CSI-RS.
The second way: the pilot period of CSI-RS and subframe skew are carried out to combined coding.
The value of supposing N is { 1,2,3,4,5,6,7,8}, in so corresponding and each CSI-RS cycle, the possibility of subframe skew is respectively { 3,6,9,12,15,18,21,24}, the total 3+6+9+12+15+18+21+24=108 kind of combination of different pilot period and subframe skew on the whole, needs altogether 7 bits to indicate cycle and the subframe skew of CSI-RS.These 7 bits can have 128 kinds of states, can choose wherein any 108 kinds of states and 108 kinds of cycles and subframe offset combinations and set up mapping table one to one, and UE receives after these 7 bits, can obtain by tabling look-up corresponding cycle and sub-frame offset information.
Preferably, in order further to reduce the expense of signaling, possibility that can antithetical phrase vertical shift value limits.For example, require front 5 subframes of every 5N subframe just can carry CSI-RS, now for any CSI-RS cycle, subframe skew value has at most 3 kinds of possibilities, i.e. { 1,2,3}.In this case, still can be by above two kinds of modes the pilot period to CSI-RS and subframe skew encode.While encoding according to first kind of way, need 3+2=5 bit; While encoding according to the second way, need 5 bits.
Wherein, the value of above-mentioned N can have multiple possibility, but can be by above two kinds of modes the pilot period to CSI-RS and subframe skew encode, the present embodiment does not limit the occurrence of N.
No matter adopt above-mentioned which kind of mode to carry out associated coding to pilot period with subframe skew, the coding result obtaining is referred to as the second coding result, for clearly every kind of concrete pilot period and subframe skew that coding result is corresponding, the network equipment, after obtaining the second coding result, also needs to set up the corresponding relation of the second coding result and pilot period and subframe skew.
203: encoded in quiet data position, obtain the 3rd coding result;
For this step, the network equipment is used the mode of bitmap (bitmap) to indicate quiet RE at CSI-RS place, Serving cell OFDM(Orthogonal Frequency Division Multiplexing, OFDM) position in symbol.
During specific implementation, carry out the quiet a part of positional information of data and can be carried by the positional information implicit expression of Serving cell CSI-RS.Specifically, Serving cell only may be quiet in subframe and the enterprising row data of OFDM symbol of carrying CSI-RS, and therefore the skew of the quiet subframe of data and the subframe of CSI-RS are offset identically, do not need independent notice; The quiet OFDM character position of data is identical with the OFDM symbol at CSI-RS pilot frequency design place, does not also need independent notice.
Particularly, take the network equipment, use 12 bits to indicate the position of quiet RE in the OFDM symbol of CSI-RS place, Serving cell as example by the mode of bitmap, now, indicate 12 bits of quiet RE to correspond respectively to 12 2 port pilot frequency designs on identical OFDM symbol, as shown in the 9th and the 10th OFDM symbol in Fig. 3, wherein each pilot frequency design comprises a pair of RE, if certain bit is 1, represent that corresponding RE needs quiet, if certain bit is 0, represent that corresponding RE does not need quiet.
In order further to reduce expense, the network equipment can be used K bit to indicate the position of quiet RE in the OFDM symbol of CSI-RS place, Serving cell, wherein K≤12 by the mode of bitmap.Now, K determines by carrying the factors such as the maximum pilot frequency design number on the OFDM symbol of Serving cell CSI-RS, quiet scope, quiet pilot frequency design.
Take Fig. 3 as example, if Serving cell CSI-RS is on the 5th and the 6th OFDM symbol, on this OFDM symbol, comprise 4 kind of 2 port pilot frequency design, K can be taken as 4 so, now, indicates 4 bits of quiet RE to correspond respectively to 42 port pilot frequency designs on the 5th and the 6th OFDM symbol, if certain bit is 1, represent that corresponding RE needs quiet, if certain bit is 0, represent that corresponding RE does not need quiet.
If network side has stipulated quiet set or quiet scope, quiet of data can occur in quiet set under the CSI-RS of Serving cell or quiet scope, now quiet set or quiet scope can be notified by alternate manner, and the embodiment of the present invention is not specifically limited this.Take Fig. 3 as example, if Serving cell CSI-RS is on the 9th and the 10th OFDM symbol, and quiet scope is limited at label, be in 2 RE, in these RE, comprise 4 kind of 2 port pilot frequency design, K can be taken as 4 so, now, indicate 4 bits of quiet RE to correspond respectively to 42 port pilot frequency designs that RE that on the 9th and the 10th OFDM symbol, label is 2 comprises, if certain bit is 1, represent that corresponding RE needs quiet, if certain bit is 0, represent that corresponding RE does not need quiet.
Take Fig. 3 as example, if Serving cell CSI-RS is on the 9th and the 10th OFDM symbol, on this OFDM symbol, comprise 6 kind of 4 port pilot frequency design, K can be taken as 6 so, now, indicate 6 bits of quiet RE to correspond respectively to 64 port pilot frequency designs on the 9th and the 10th OFDM symbol, wherein each pilot frequency design comprises two couples of RE, if certain bit is 1, represents that corresponding RE needs are quiet, if certain bit is 0, represent that corresponding RE does not need quiet.
The value of K can have multiple possibility, but can to quiet RE, indicate the position in the OFDM symbol of CSI-RS place, Serving cell by the mode of bitmap, and the present embodiment does not limit the occurrence of K.
No matter adopt above-mentioned which kind of mode to encode to the quiet position of data, the coding result obtaining is referred to as the 3rd coding result, for clear and definite every kind of quiet position of concrete data that coding result is corresponding, the network equipment, after obtaining the 3rd coding result, also needs to set up the corresponding relation of the 3rd coding result and the quiet position of data.
204: quiet to data mute periods and data skew is carried out to associated coding, obtain the 4th coding result;
For this step, partial data is quiet to be referred to not to all carrying out quiet with the data RE of CSI-RS collision, for example CSI-RS sends once every 5ms, and data are quiet, every 15ms, occurs once, and now the network equipment also needs to UE notification data mute periods and the skew of data mute subframe.Due to only may be quiet in subframe and the enterprising row data of OFDM symbol of carrying CSI-RS, therefore data mute periods be the CSI-RS cycle positive integer doubly, tentation data mute periods is 5NMms.In the time of 5NMms, the network equipment can send CSI-RS M time, and in the quiet any CSI-RS subframe that may occur in wherein of data, so also need the quiet side-play amount of notification data, i.e. the quiet skew of data.
For the coding of data mute periods and the quiet skew of data, can adopt any realization in following two kinds of modes:
First kind of way: the quiet skew of data mute periods and data is encoded respectively.
Suppose that the value of M is for { 1,2,3,4,5} needs 3 bits to indicate the cycle of CSI-RS so.For quiet skew, when N=5, there are at most 5 kinds of possibilities, so need 3 bits indicate the subframe skew of CSI-RS.On the whole, need altogether 3+3=6 bit to indicate cycle and the subframe skew of CSI-RS.
The second way: combined coding is carried out in the quiet skew of data mute periods and data.
The value of supposing M is { 1,2,3,4,5}, so corresponding to each mute periods, the possibility of quiet skew is respectively { 1,2,3,4,5}, the total 1+2+3+4+5=15 kind of combination of different cycles and subframe skew on the whole, needs altogether 4 bits to indicate cycle and the subframe skew of CSI-RS.These 4 bits can have 16 kinds of states, can choose wherein any 15 kinds of states and 15 kinds of cycles and offset combinations and set up mapping table one to one, and UE receives after these 4 bits, can obtain by tabling look-up corresponding cycle and sub-frame offset information.
Preferably, in order further to reduce the expense of signaling, can limit the possibility of the quiet skew value of data.For example, in the time of 5NMms, the network equipment can send CSI-RS M time, require that data are quiet can only be occurred in for the first time in CSI-RS subframe, now, for arbitrary data mute periods, the quiet skew value of data only has a kind of possibility, so do not need to notify quiet skew.In this case, only need to encode to data mute periods, suppose that the value of M is for { 1,2,3,4,5} needs 3 bits.
Wherein, the value of M can have multiple possibility, but can be by above two kinds of modes the cycle to CSI-RS and subframe skew encode, the present embodiment does not limit the occurrence of M and N.
No matter adopt above-mentioned which kind of mode data mute periods to carry out associated coding with the quiet skew of data, the coding result obtaining is referred to as the 4th coding result, for clearly every kind of concrete data mute periods and quiet skew of data that coding result is corresponding, the network equipment, after obtaining the 4th coding result, also needs to set up the corresponding relation of the 4th coding result and data mute periods and the quiet skew of data.
In addition, by above-mentioned steps 201 to step 204, the network equipment obtains first, second, after the third and fourth coding, for when notifying CSI-RS configuration information at every turn, need not repeat it to carry out encoding operation, the network equipment also needs to store the corresponding relation of the first coding result and port number and pilot frequency design, the corresponding relation of the second coding result and pilot period and subframe skew, the corresponding relation of the 3rd coding result and the quiet position of data, the corresponding relation of the 4th coding result and data mute periods and the quiet skew of data, thereby after the network equipment is determined on call CSI-RS configuration information, only need in the mapping relations of storage, find the CSI-RS configuration information coding that this on call CSI-RS configuration information is corresponding, and CSI-RS configuration information coding is sent to UE.
205: CSI-RS configuration information coding is notified to UE by down channel, and this CSI-RS configuration information is encoded to arbitrary coding result in arbitrary coding result, the 3rd coding result in arbitrary coding result, the second coding result in the first coding result and the arbitrary coding result in the 4th coding result.
For this step, in order to make the UE that receives CSI-RS configuration information coding determine its corresponding CSI-RS configuration information according to the CSI-RS configuration information coding receiving, the network equipment self is being stored after the mapping relations of CSI-RS configuration information coding and CSI-RS configuration information, also need to send it to UE and store, make UE determine CSI-RS configuration information according to the CSI-RS configuration information coding of the CSI-RS configuration information coding receiving and UE storage with the mapping relations of CSI-RS configuration information.
Particularly, the mode of transmission CSI-RS configuration information coding includes but not limited to following several:
The first: increase the bit for carrying CSI-RS configuration information coding in the system information block of broadcast channel, for example, increase corresponding bit and be used for carrying CSI-RS information in the 2nd system information block (SIB2) of broadcast channel.
The second: utilize MIB(Master Information Block in broadcast channel, Master Information Block) in unnecessary bit carrying CSI-RS configuration information coding, for example, in broadcast channel, utilize 10 unnecessary bit carrying CSI-RS information in Master Information Block.
The third: in broadcast channel, definition is for carrying the new system information block of CSI-RS configuration information coding, for example, in broadcast channel, define x system information block (SIBx) for carrying CSI-RS information, wherein port number information can scrambled to the CRC of SIBx, the present embodiment does not limit the occurrence of x.
The 4th kind: utilize unicast tunnel carrying CSI-RS configuration information, for example, utilize down control channel carrying CSI-RS configuration information.
So far, CSI-RS configuration information coding is notified to after UE by down channel, UE can determine with the mapping relations of CSI-RS configuration information the concrete CSI-RS configuration information that the network equipment sends according to CSI-RS configuration information coding and the CSI-RS configuration information coding of UE storage, according to CSI-RS configuration information, can determine the position of CSI-RS, thereby can carry out the operations such as down channel estimation.
