Information notified to UE, makes UE determine CSI-RS configuration information according to CSI-RS configuration information coding, can not only reduce expense, also
The CSI-RS that ensure that more multiple cell is not mutually collided.
Embodiment two
A kind of method of notification reference signal configuration information is present embodiments provided, expense is little, week because CSI-RS has
The characteristics of phase length, multiplexing factor height, high port pilot frequency design nesting low port pilot frequency design, therefore, the present embodiment is by right
CSI-RS configuration information is encoded, and CSI-RS configuration information is notified to UE in the form of CSI-RS configuration information coding,
UE is set to determine CSI-RS configuration information, so as to reach reduction expense, it is ensured that the purpose that the CSI-RS of more multiple cell is not mutually collided.
Wherein, the equipment of notification reference signal configuration information is the network equipment, and CSI-RS configuration information includes but do not limit
In port number, pilot frequency design, pilot period and sub-frame offset.
If the data symbol that the CSI-RS of certain cell and strong jamming cell send mutually is collided, the network equipment can be wanted
Ask on the position of the CSI-RS sent out in the cell, strong jamming cell all does digital silence（muting）Process, it is to avoid to reference to letter
Number interference.Now the cell is needed CSI-RS pilot frequency locations（Including pilot period and pilot frequency design etc.）Notify to each
Strong jamming cell.Additionally, the network equipment is also needed to the digital silence position informing of CSI-RS to UE, UE is set to assume in the position
Transmission without data symbol, receiver does not carry out Data Detection in the position, and UE estimates under respective cell on the position
Row channel.Support the situation of digital silence technology for this kind of network equipment, CSI-RS configuration information except including port number,
Pilot frequency design, pilot period and sub-frame offset, also including digital silence position.
If the network equipment is on the basis of digital silence is supported, support section digital silence is gone back, then the network equipment is also needed
Digital silence cycle and digital silence skew are notified into that to UE, for this kind of situation, CSI-RS configuration information is except including end
Mouth number, pilot frequency design, pilot period, sub-frame offset and data mute position, also including digital silence cycle and digital silence
Skew.
Below, the present embodiment both supported as a example by digital silence technology, and support section digital silence technology with the network equipment,
The method that the present embodiment is provided is described in detail.Now, CSI-RS configuration information both include port number, pilot frequency design,
Pilot period, sub-frame offset and data mute position, also offset, referring to Fig. 2, this reality including digital silence cycle and digital silence
The method flow for applying example offer is specific as follows：
201：Port number and pilot frequency design are associated coding by the network equipment, obtain the first coding result；
Wherein, CSI-RS port numbers have 2,4,8 three kind of possibility, the different port number of pilot frequency design correspondence and different
Sub-frame configuration has following several possibility, as shown in table 1：
Table 1
| CSI-RS port numbers | 2 | 4 | 8 |
| Common CP can use CSI-RS pilot frequency number | 20 | 10 | 5 |
| Common CP w/o CRS ports2/3 can use CSI-RS pilot frequency number | 32 | 16 | 8 |
| Extension CP can use CSI-RS pilot frequency number | 16 | 8 | 4 |
| Extension CP w/o CRS ports2/3 can use CSI-RS pilot frequency number | 28 | 14 | 7 |
As shown in table 1, the different port number of pilot frequency design correspondence is up to respectively 32（2 ports）、16（4 ports）、8（8
Port）Planting may.In general, port number and pilot frequency design are up to 32+16+8=56 kinds possibility.Then by port number with
When pilot frequency design is associated coding, can be being realized using any one mode in following two modes：
First kind of way：Port number and pilot frequency design are carried out into combined coding with 6 bits.
6 bit signalling can indicate 64 kinds of states, it is possible to use wherein any 56 kinds of states, and they are held with 56 kinds
Mouth number combines one-to-one corresponding with pilot frequency design, sets up a mapping table.Therefore, UE is by receiving this 6 bit signalling and searching
Mapping table, can learn the port number and pilot frequency design of CSI-RS.
Specifically, it is contemplated that when port number is respectively 2,4,8, the pilot frequency design of CSI-RS has nested characteristic, i.e.,
Each 8 port pilot frequency design can be with nested two 4 port pilot frequency designs, each 4 port pilot frequency design two 2 port pilot tone of nesting
Pattern, if 8 port pilot frequency designs are divided into into before and after two parts, each part is a 4 port pilot frequency designs；If by 4 ends
Mouth pilot frequency design is divided into before and after two parts, and each part is a 2 port pilot frequency designs.Based on this Nested property, Ke Yitong
Cross the mapping relations that following two steps determine port number and pilot frequency design：
The first step：3 bits of lowest order and 8 kinds of pilot frequency designs of 8 ports set up corresponding relation, and the present embodiment is not to most
3 bits of low level are specifically limited with the corresponding relation of 8 port pilot frequency designs, are only closed with the correspondence shown in table 2 below
As a example by system：
Table 2
| 8 port pilot frequency designs | Coding |
| The first 8 port pilot frequency design | 000 |
| Second 8 port pilot frequency designs | 001 |
| The third 8 port pilot frequency design | 010 |
| 4th kind of 8 port pilot frequency design | 011 |
| 5th kind of 8 port pilot frequency design | 100 |
| 6th kind of 8 port pilot frequency design | 101 |
| 7th kind of 8 port pilot frequency design | 110 |
| 8th kind of 8 port pilot frequency design | 111 |
When port number is 2 or 4,3 bits of the lowest order represent that 8 ports for being capable of nested indicated pilot frequency design are led
Frequency pattern.The numbering of the corresponding 8 port pilot frequency design of mapping table is 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 the 10, the 3rd bit indicates that 4 port pilot frequency designs are being nested
8 port pilot frequency designs in position, 0 represent first half, 1 represent latter half；
When port number is 2,1 bit of highest order is 0；2nd bit indicates that 2 port pilot frequency designs are being nested
Position in 4 port pilot frequency designs, 0 represents first half, and 1 represents latter half；
If without CSI-RS, can be represented with " 111111 ", then specific mapping relations are as shown in Table 3 below：
Table 3
Wherein, the x in table 3 in 3 bits of lowest order represents the corresponding relation set up with 8 kinds of pilot frequency designs of 8 ports,
So that the result of port number and pilot frequency design combined coding is for 100101 as an example, due to 3 of the highest order in the coding result
Bit is 100, from table 3 it is observed that the corresponding port number of the coding result is 4 ports, and 4 port is 8 ports
Pattern first half.Further, since 3 bits of the lowest order in the coding result are 101, can be seen that from above-mentioned table 2
For the 5th kind of 8 port pilot frequency design.
The second way：Port number and pilot frequency design are separately encoded.
When implementing, by the CRC of port number scrambled to x-th SIB（Cyclic Redundancy Check,
CRC）On, pilot frequency design is indicated by the signaling of 5 bits.
Wherein, x-th system information block is the system information block for configuring CSI-RS information.Nesting based on CSI-RS
Characteristic, can obtain the mapping relations of the signaling and pilot frequency design of 5 bits by following two steps：
The first step：3 bits of lowest order and 8 kinds of pilot frequency designs of 8 ports set up one-to-one relation, work as port number
For 2 or 4 when, these three bits represent the 8 port pilot frequency designs for being capable of 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 tones
Position of the pattern in 8 port pilot frequency designs being nested, 0 represents first half, and 1 represents latter half；
When port number is 2, the 1st bit indicates position of the 2 port pilot frequency designs in 4 port pilot frequency designs being nested
Put, 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.
By taking 2 port pilot frequency designs as an example, it can be divided into 2 pilot frequency designs according to 4 port pilot frequency design first halfs and latter half
Group, it is now, above-mentioned that port number and pilot frequency design are associated into the 2nd bit in the first kind of way of coding and second
The 1st bit in mode can indicate affiliated pilot frequency design group.
Further, above-mentioned 2 pilot frequency design groups are further divided into according to 8 port pilot frequency design first halfs and latter half
4 pilot frequency design groups, now the 1st and the 2nd bit in the 2nd and the 3rd bit and the second way in first kind of way
Position can indicate affiliated pilot frequency design group.By taking 4 port pilot frequency designs as an example, it can be according to 8 port pilot frequency design first halfs
Divide and latter half is divided into 2 pilot frequency design groups, now the 2nd in the 3rd bit and the second way in first kind of way
Bit can indicate affiliated pilot frequency design group.
It should be noted that the first half of 8 port pilot frequency designs alleged by the present embodiment, refers to 8 port pilot patterns
Case is divided into two parts according to by 4 port pilot frequency designs of its nesting, wherein forward part, can be that 8 port pilot frequency designs are whole
The first half of body, or per the first half in half 8 port pilot frequency design, to be numbered 0 pilot frequency design in Fig. 3
As a example by, four rows are had from top to bottom, both front two row can be referred to as first half, it is also possible to by the first row in front two row with after
The first row in two rows is referred to as first half, and the present embodiment is not especially limited to this, the first half of 4 port pilot frequency designs
The first half implication of the same 8 port pilot frequency designs of implication, the present embodiment is equally not especially limited.No matter above-mentioned which kind of side is adopted
Formula is associated coding to port number and pilot frequency design, and the coding result for obtaining is referred to as the first coding result, in order to clear and definite
The corresponding concrete port number of every kind of coding result and pilot frequency design, the network equipment is also needed after the first coding result is obtained
The first coding result is set up with port number and the corresponding relation of pilot frequency design.
202：Pilot period and sub-frame offset are associated into coding, the second coding result is obtained；
Wherein, the pilot period of CSI-RS is 5 milliseconds of multiple, it is assumed that the CSI-RS cycles are 5N milliseconds, and N is positive integer,
Then the value of N is specified that each millisecond corresponds to a subframe by R10 specifications.Sub-frame offset refers to all in a certain CSI-RS
Under phase, the subframe of CSI-RS is carried relative to benchmark subframe（First subframe in i.e. 5N subframe）Sub-frame offset.By
In in R10 specifications it has been specified that may need to carry synchronizing channel, broadcast in the 0th per 5 subframes and the 4th subframe
The information such as channel, paging channel, so these subframes can not carry CSI-RS, therefore the CSI-RS cycles of correspondence 5N ms, subframe
Skew is up to 3N kind probabilities.
Pilot period for CSI-RS can be with using any one of following two modes with the coding of sub-frame offset：
First kind of way：The pilot period of CSI-RS and sub-frame offset are encoded respectively.
The value for assuming N is { 1,2,3,4,5,6,7,8 }, then needing 3 bits to indicate the cycle of CSI-RS.For
Sub-frame offset, as N=8, be up to 24 kinds possibility, so needing 5 bits to indicate the sub-frame offset of CSI-RS.It is overall next
Say, 3+5=8 bit is needed altogether to indicate cycle and the sub-frame offset of CSI-RS.
The second way：The pilot period of CSI-RS and sub-frame offset are carried out into combined coding.
The value for assuming N is { 1,2,3,4,5,6,7,8 }, then correspondence and each CSI-RS cycle, sub-frame offset
Probability is respectively { 3,6,9,12,15,18,21,24 }, on the whole different pilot periods 3+ total with the combination of sub-frame offset
6+9+12+15+18+21+24=108 kinds, need altogether 7 bits to indicate cycle and the sub-frame offset of CSI-RS.This 7 ratios
Spy can have 128 kinds of states, can choose wherein any 108 kinds of states and foundation is combined with sub-frame offset one by one with 108 kinds of cycles
Corresponding mapping table, UE is received after this 7 bits, can obtain corresponding cycle and sub-frame offset information by tabling look-up.
Preferably, in order to further reduce the expense of signaling, the probability of sub-frame offset value can be limited.Example
Such as, it is desirable to which front 5 subframes per 5N subframe could carry CSI-RS, and at this point for any CSI-RS cycles, sub-frame offset takes
Value is up to 3 kinds of probabilities, i.e. { 1,2,3 }.In this case, still CSI-RS can be led by both the above mode
The frequency cycle is encoded with sub-frame offset.When encoding according to first kind of way, 3+2=5 bit is needed；According to the second way
During coding, 5 bits are needed.
Wherein, the value of above-mentioned N can have various probabilities, but CSI-RS can be led by both the above mode
The frequency cycle is encoded with sub-frame offset, and the present embodiment is not defined to the occurrence of N.
No matter coding is associated to pilot period and sub-frame offset using above-mentioned which kind of mode, the coding result system for obtaining
Referred to as the second coding result, for the corresponding concrete pilot period of clearly every kind of coding result and sub-frame offset, the network equipment exists
After obtaining the second coding result, in addition it is also necessary to set up the second coding result with pilot period and the corresponding relation of sub-frame offset.
203：Digital silence position is encoded, the 3rd coding result is obtained；
For the step, the network equipment uses bitmap（bitmap）Mode indicate quiet RE in Serving cell CSI-RS
Place OFDM（Orthogonal Frequency Division Multiplexing, OFDM）Position in symbol
Put.
When implementing, a part of positional information for carrying out digital silence can be by the positional information of Serving cell CSI-RS
Implicit expression is carried.Specifically, Serving cell is only possible to that digital silence can be carried out in the subframe and OFDM symbol for carrying CSI-RS,
Therefore the sub-frame offset of digital silence is identical with the sub-frame offset of CSI-RS, it is not necessary to be notified independently；The OFDM symbols of digital silence
Number position is identical with the OFDM symbol that CSI-RS pilot frequency is located, it is not required that be notified independently.
Specifically, indicate quiet RE in Serving cell by way of bitmap using 12 bits with the network equipment
As a example by position in the OFDM symbol of CSI-RS places, now, 12 bits for indicating quiet RE correspond respectively to identical OFDM
12 2 port pilot frequency designs on symbol, as shown in the 9th and the 10th OFDM symbol in Fig. 3, wherein each pilot frequency design bag
Containing a pair of RE, if certain bit is 1, represent that corresponding RE needs quiet, if certain bit is 0, represent corresponding
RE need not be quiet.
In order to further reduce expense, the network equipment can be quiet to be indicated by way of bitmap using K bit
Positions of the RE in the OFDM symbol of Serving cell CSI-RS places, wherein K≤12.Now, K is by carrying Serving cell CSI-RS's
The factors such as maximum pilot frequency design number, quiet scope, quiet pilot frequency design in OFDM symbol are determined.
By taking Fig. 3 as an example, if Serving cell CSI-RS is in the 5th and the 6th OFDM symbol, 4 are included in the OFDM symbol
Plant 2 port pilot frequency designs, then K can be taken as 4, now, 4 bits for indicating quiet RE correspond respectively to the 5th and the 6th
42 port pilot frequency designs in OFDM symbol, if certain bit is 1, represent that corresponding RE needs quiet, if certain
Bit is 0, represents that corresponding RE need not be quiet.
If network side defines quiet set or quiet scope, digital silence only occurs in Serving cell CSI-RS
In affiliated quiet set or quiet scope, now quiet set or quiet scope can be notified otherwise,
The embodiment of the present invention is not specifically limited to this.By taking Fig. 3 as an example, if Serving cell CSI-RS is accorded with the 9th and the 10th OFDM
On number, and quiet scope is limited in the RE for being numbered 2, and 4 kind of 2 port pilot frequency design is included in these RE, then K can be with
4 are taken as, now, 4 bits for indicating quiet RE correspond respectively to be numbered 2 RE institutes in the 9th and the 10th OFDM symbol
Comprising 42 port pilot frequency designs, if certain bit is 1, represent that corresponding RE needs quiet, if certain bit
For 0, represent that corresponding RE need not be quiet.
By taking Fig. 3 as an example, if Serving cell CSI-RS is in the 9th and the 10th OFDM symbol, 6 are included in the OFDM symbol
Plant 4 port pilot frequency designs, then K can be taken as 6, now, 6 bits for indicating quiet RE correspond respectively to the 9th and the 10th
64 port pilot frequency designs in individual OFDM symbol, wherein each pilot frequency design include two couples of RE, if certain bit is 1,
Represent that corresponding RE needs quiet, if certain bit is 0, represent that corresponding RE need not be quiet.
The value of K can have various probabilities, but can by way of bitmap to quiet RE in Serving cell
Position in the OFDM symbol of CSI-RS places is indicated that the present embodiment is not defined to the occurrence of K.
Which kind of no matter data mute position is encoded using above-mentioned mode, the coding result for obtaining is referred to as the 3rd volume
Code result, for the corresponding concrete digital silence position of clearly every kind of coding result, the network equipment is obtaining the 3rd coding result
Afterwards, in addition it is also necessary to set up the corresponding relation of the 3rd coding result and digital silence position.
204：Digital silence cycle and digital silence skew are associated into coding, the 4th coding result is obtained；
For the step, quiet data RE referred to not to all colliding with CSI-RS of partial data carry out quiet, example
As CSI-RS sends once every 5ms, and digital silence occurs once every 15ms, and now the network equipment also needs to logical to UE
Primary data mute periods and digital silence sub-frame offset.Due to being only possible to be carried out in the subframe and OFDM symbol for carrying CSI-RS
Digital silence, therefore the digital silence cycle is the positive integer times in CSI-RS cycles, it is assumed that the digital silence cycle is 5NMms.5NMms
Time in, the network equipment can send M CSI-RS, and digital silence is likely to occur in any CSI-RS subframe therein
On, so also needing to notify the side-play amount of digital silence, i.e. digital silence skew.
Can be with using any one of following two modes for the coding in digital silence cycle and digital silence skew
Realize：
First kind of way：The digital silence cycle is encoded respectively with digital silence skew.
The value for assuming M is { 1,2,3,4,5 }, then needing 3 bits to indicate the cycle of CSI-RS.It is inclined for quiet
Move, as N=5, be up to 5 kinds possibility, so needing 3 bits to indicate the sub-frame offset of CSI-RS.On the whole, altogether
Need 3+3=6 bit to indicate cycle and the sub-frame offset of CSI-RS.
The second way：The digital silence cycle carries out combined coding with digital silence skew.
The value for assuming M is { 1,2,3,4,5 }, then corresponding to each mute periods, the probability point of quiet skew
It is not { 1,2,3,4,5 } that on the whole different cycles and the total 1+2+3+4+5=15 kinds of the combination of sub-frame offset, need altogether 4
Individual bit is indicating cycle and the sub-frame offset of CSI-RS.This 4 bits can have 16 kinds of states, can choose wherein any 15
The state of kind sets up one-to-one mapping table with 15 kinds of cycles and offset combinations, and UE is received after this 4 bits, can be by looking into
Table obtains corresponding cycle and sub-frame offset information.
Preferably, in order to further reduce the expense of signaling, the probability that digital silence offsets value can be limited
System.For example, in the time of 5NMms, the network equipment can send M CSI-RS, it is desirable to which digital silence can only occur in for the first time
In CSI-RS subframes, at this point for arbitrary data mute periods, digital silence skew value only has a kind of probability, so being not required to
Notify quiet skew.In this case, it is only necessary to which data mute periods are encoded, it is assumed that the value of M for 1,2,3,
4,5 }, 3 bits are needed.
Wherein, the value of M can have various probabilities, but can by both the above mode to cycle of CSI-RS with
Sub-frame offset is encoded, and the present embodiment is not defined to the occurrence of M and N.
No matter coding is associated with digital silence skew using above-mentioned which kind of in mode digital silence cycle, the coding for obtaining
