Description
Technical field
The present invention relates to communication technical field, in particular to a kind of collocation method of reference signal, a kind of reference letter
Number configuration system, a kind of equipment with base station functions, a kind of method of reseptance of reference signal, a kind of reception of reference signal
System and a kind of terminal.
Background technology
With sharply increasing for message volume, the frequency spectrum that authorizes of 3GPP is increasingly not enough to provide higher network appearance
Amount.In order to further improve the utilization rate of frequency spectrum resource, 3GPP is just discussing how unauthorized is used with the help of frequency spectrum is authorized
Frequency spectrum, such as 2.4GHz and 5GHz frequency ranges.These unlicensed spectrums are presently mainly that the systems such as Wi-Fi, bluetooth, radar, medical treatment exist
Use.
Under normal circumstances, be authorized frequency range design access technology, such as LTE (Long Term Evolution, for a long time
Evolution) be not suitable for being used in unauthorized frequency range, because this kind of access technologies of LTE are wanted to spectrum efficiency and Consumer's Experience optimization
Ask very high.However, carrier aggregation (Carrier Aggregation, CA) function allows and LTE is deployed in into unauthorized frequency range is changed into
May.3GPP proposes the concept of LAA (LTE Assisted Access, LTE auxiliary is accessed), and by LTE the side of frequency spectrum is authorized
Help to use unlicensed spectrum.And unlicensed spectrum can have two kinds of working methods, one kind be supplement it is descending (SDL,
Supplemental Downlink), i.e. only downlink transfer subframe；Another kind is tdd mode, both comprising descending sub frame, up
Subframe.The fact that supplement is descending can only use (as shown in Figure 1) by carrier aggregation technology.And tdd mode is except can be with
By carrier aggregation technology using outer, can be using by DC (Dual Connectivity, doubly-linked leads to), it is also possible to independent
Use.
Compared to Wi-Fi systems, the LTE system for being operated in unauthorized frequency range has the ability to provide higher spectrum efficiency and more
Big coverage effect, while allowing data traffic authorizing between frequency range and unauthorized frequency range without seaming and cutting based on same core net
Change.For user, it means that preferably broadband experience, higher speed, more preferable stability and movement is facilitated.
The existing access technology used in unlicensed spectrum, such as Wi-Fi, with weaker capacity of resisting disturbance.In order to
Avoid interference, many interference of Wi-Fi system designs avoid rule, such as CSMA/CD (Carrier Sense Multiple
Access/Collision Detection, csma/collision detection method), the ultimate principle of this method
It is that either terminal, first Monitor detection week before signaling or data are sent for the AP (Access Point, access point) of Wi-Fi
Whether have other APs or other-end in transmission/reception signaling or data, if having, continue to monitor, until listening to not if enclosing
Till having；If a random number N no, is generated as back off time, in ensuing Channel Detection, if detecting channel
Busy, then N is constant, idle again until detecting channel, could N-1；When N is kept to 0, back off time terminates, and AP or terminal can
To start to send signaling or data.The process is as shown in Figure 2.
But, due to there is good orthogonality to ensure that interference level in LTE network, so the up-downgoing of base station and user
Transmission is without considering whether surrounding has other base stations or other users in transmission data.If LTE is used in unauthorized frequency range
When do not consider yet around whether have other equipment using unauthorized frequency range, then greatly interference will be brought to Wi-Fi equipment.
If because LTE has business to be just transmitted, without any monitoring rule, then Wi-Fi equipment when LTE has business to transmit just
Can not transmit, can only be transmitted when LTE business, can just detect channel clear to carry out data transmission.
So LTE is when using unauthorized frequency range, one of topmost key point is to ensure that LAA (LTE assisted
The access technology of access, LTE auxiliary) can be on the basis of fair close friend with existing access technology (such as WiFi) altogether
Deposit.And the mechanism without LBT (Listen Before Talk, listem-before-talk) carrys out collision free in traditional LTE system.In order to
Preferably coexist with WiFi, LTE needs a kind of LBT mechanism.So, LTE in unlicensed spectrum if detecting channel busy, then
The frequency range can not be taken, if detecting the channel spare time, could be taken.
Based on the problems referred to above, at present, it is proposed that a kind of (FBE, Framed based equipment) based on frame structure
LBT mechanism (as shown in Figure 3), left oblique line is the channel of CCA (Clear Channel Assessment, clear channel assessment (CCA))
Detection time, CCA detection times are repeated cyclically appearance, if detecting channel idle, busy channel, in Channel holding time
After reaching maximum channel holding time, there are an idle times, in the idle times, sending point not sending signal and data, with
It is easy to other sending points to seize channel.After the idle times, occur CCA detection times again, if detecting channel busy, do not account for
With channel, channel is detected again when the CCA detection times in next cycle occur.Certainly, Channel Detection Time falls within
Idle times, idle durations have to be larger than the 5% of channel maximum holding time.The CCA times add upper signal channel to account for plus the Idle times
It it is the cycle with maximum time.
At present, it is also proposed that a kind of following Fig. 4 of LBT mechanism of (LBE, Load based equipment) based on load
It is shown：It is aperiodic based on the LBT mechanism of LBE, as long as business is reached, then triggers CCA detections, if CCA detections are idle,
Signaling or data are sent at once；If detecting channel busy, a random number N is taken, the span of N (the i.e. contention window that is 1 to q
Mouth length), the span of q is 4 to 32.Fig. 4 shows a case that q=16, now, when channel idle is detected, channel
Maximum holding time is (13/32) x q=6.5ms.After 6.5ms, extended CCA are taken (during the Channel Detection of prolongation
Between) mechanism, that is, it is also random value N, the scope of N is 1 to 16, if value is 8, then it represents that examined in ensuing continuous CCA
In the survey time, each CCA detection time will detect channel, if detecting channel idle, N-1, and if detecting channel busy,
N is constant, when N is 0, sends signaling or data.
In addition, in LAA for RRM (Radio Resource Management, RRM) measurement, cell
The reference signal of identification, down-going synchronous, time-frequency estimation etc. has two ways to realize：One kind is short control
Signaling (control signal in short-term), it is the time that can have 5% in 50ms to send short that this mode needs the requirement for meeting
When control signal, that is, 2.5ms.Another kind is that (Discovery Reference Signal send out the aperiodic DRS of transmission
Referring now to signal) because sending DRS need to take the time of 6ms, and if also sent when channel busy is detected, will be to other
System brings larger interference, so if sending DRS, just can only send when channel idle is detected, then DRS is exactly
It is aperiodic.
When DRS must at present have various methods when detecting channel idle and could send：
First method：DRS must be in DMTC (DRS Measurement Timing as R12
Configuration, DRS time of measuring is configured) in send in fixed subframe (subframe).PSS/SSS in such as DRS
Must assure that and sent on original subframe original symbol (symbol).For FDD (Frequency Division
Duplexing, FDD) for, PSS as shown in Figure 5 0# subframes and 5# subframes first slot (time slot) it is last
Send on one symbol (i.e. numbering is 6 the 7th symbol)；SSS (Secondary Synchronization Signal,
Auxiliary synchronous signals) with PSS (Primary Synchronization signal, master sync signal) in the same slot of same subframe
Send, but SSS is located in penultimate symbol, and than PSS previous symbol is carried (i.e. numbering is 5 the 6th symbol).It is right
For TDD (Time Division Duplexing, time division duplex), as shown in fig. 6, PSS in 1# subframes and 6# subframes (i.e.
Send in 3rd symbol of numbering 2 DwPTS)；And SSS is in subframe 0# subframe and last symbol of 5# subframes
Send in (i.e. the 14th symbol of numbering 13), than PSS 3 symbol are shifted to an earlier date.UE detection complexities are this approach reduces,
Simultaneously when RRM measurements are carried out, it is possible to achieve sign synchronization, synchronizing sub-frame, frame synchronization.But this has the disadvantage the transmitter of DRS
Can lack, if being not detected by channel idle in only send opportunity in a DMTC cycle (minimum 40ms), not have
Method sends.Need to wait until the send opportunity in the next DMTC cycles, wherein, terminal is according to 10ms cycles (i.e. one frame structure)
Two interior PSS are identical, two SSS differences, it can be determined that going out base station is sent in subframe#0 or subframe#5
DRS。
Second method：During DMTC, DRS can send in unfixed subframe, when detect
When channel idle then sends, and the advantage of this method is that send opportunity is more.Have the disadvantage that UE detection complexities increase, and by
Do not know in positions such as the transmission symbol that PSS/SSS takes, subframe so that terminal cannot realize subframe synchronizations,
The functions such as frame synchronization.
The third method：Outside in the DMTC cycles sends DRS, that is to say, that as long as detecting channel idle, it is possible to
Send DRS.And the advantage of this method further increases send opportunity compared to second method, have the disadvantage than the first UE
Detection complexity is higher, in some instances it may even be possible to need eNB (base station) DCI signalings (Downlink Control Information, under
Row control information) go further to indicate the transmission time of DRS.
Therefore, how while DRS transmission probability is increased, the complexity that UE detects DRS can be as far as possible reduced, so that terminal
DRS is accurately received, so as to realize the synchronization of frame synchronization and subframe, becomes problem demanding prompt solution.
The content of the invention
The present invention is based on the problems referred to above, it is proposed that a kind of new technical scheme, and in increase DRS the same of probability is sent
When, the complexity that UE detects DRS can be as far as possible reduced, so that terminal is accurately received DRS, so as to realize the same of frame synchronization and subframe

In above-mentioned technical proposal, it is preferable that before each described discovery reference signal is sent, by arranging in DMTC
Down channel detection subframe detection down channel it is whether idle；Detect the down channel it is idle when, send with it is described
Down channel detects the nearest rearmounted discovery reference signal of the character position that subframe takes, and stops sending out in the DMTC cycles
Other are given to find reference signal；Otherwise, the rearmounted discovery reference signal is not sent；And it is empty the down channel is detected
After spare time, before the rearmounted discovery reference signal is sent, channel occupancy signal is sent, and the signal Seize ACK message takes
Symbolic number less than M, wherein, M is positive integer.
In the technical scheme, in down channel detection subframe (i.e. CCA, Clear Channel Assessment) detection
During to the downstream signal free time, by the nearest rearmounted DRS of the character position that terminal sends with CCA takes, terminal being made accurate
Really detect DRS, so as to realize frame synchronization and synchronizing sub-frame, and if after being transmitted across a DRS within a DMTC cycle, just

The normal transmission of row signal or the descending transmission of miscellaneous equipment；And after the down channel free time is detected, if also not arriving
Up to the transmission position of rearmounted discovery reference signal, then channel occupancy signal (such as preserved signal) or initial signal are sent
(initial signal) or CRS or CSI-RS, but the temporal summation for sending these signals obtains restricted, such as less than M symbol,
So both send opportunity can be striven to obtain for rearmounted transmission reference signal, the overlong time of these channel reservations can be avoided again, and
So that miscellaneous equipment cannot be robbed accounts for channel.
In above-mentioned technical proposal, it is preferable that when each described discovery reference signal is sent, using mandate frequency spectrum or non-
Authorize the down control channel on frequency spectrum to send to the terminal to be used to indicate whether to send each discovery reference signal
Downlink Control Information.
In the technical scheme, because base station notifies the sent position of how many DRS in one DMTC of terminal, terminal
Will blind check how many times, but in fact, base station detect down channel it is busy when, DRS would not be sent, which increase terminal
Detection of complex, therefore, it is DCI by sending Downlink Control Information to terminal, whether can really be sent with instruction terminal base station
DRS, This further reduces the complexity that terminal detects DRS.
In above-mentioned technical proposal, it is preferable that in the channel condition information described in discovery reference signal configuration each described

Figure 12 shows the structural representation of terminal according to an embodiment of the invention.
As shown in figure 12, the terminal 1200 of one embodiment of the present of invention is shown, including：As appointed in above-mentioned technical scheme
The reception system 1100 of the reference signal described in.
In the technical scheme, by the reception system 1100 for arranging reference signal in terminal 1200, terminal can be made
1200 can be relatively easy to, detect and receive DRS exactly, so as to realize the synchronization of frame synchronization and subframe.
Below in conjunction with the technical scheme in Figure 13 to Figure 16 further description present invention (present invention is generally directed to carry on the back
The improvement project that second method in scape technology is proposed)：
1st, the sent position of multiple DRS is configured in a DMTC, such as the length of tradition DRS is 1~5ms, then
1~5 can be configured can send position, and each sends position length and is less than or equal to 1ms.
2nd, each is sent in position, and the relative position of PSS and SSS in DRS keeps constant, and such as in fdd, SSS is in PSS
A symbol being above close to；And in TDD, SSS before PSS and be spaced two symbol.
3rd, each is sent in position, and the PSS and SSS in DRS takes fixed symbol positions.Such as, in fdd, will
PSS is arranged in last symbol of first slot (time slot) of arbitrary subframe, and SSS and PSS is arranged on same
In the same slot of subframe, but SSS is located in penultimate symbol, and than PSS previous symbol is carried；For TDD, will
PSS is arranged in the 3rd symbol of arbitrary subframe, and SSS is arranged on the preposition subframe adjacent with arbitrary subframe (as being somebody's turn to do
When arbitrary subframe is 1# subframes, preposition subframe is exactly the 0# subframes of same frame structure, and arbitrary subframe is when being 6# subframes, preposition
Subframe is exactly the 5# subframes of same frame structure) last symbol in send, shift to an earlier date 3 symbol than PSS.
4th, control DRS and continuously take N number of symbol numbers, N is greater than being equal to 3 that (the symbol numbers that DRS takes in FDD are more than
Equal to 3, as shown in Figure 5；In TDD, the symbol numbers that DRS takes are more than or equal to 4, two in the middle of PSS as shown in Figure 6 and SSS
Individual symbol must be filled), and filled with existing CRS and/or NZP CSI-RS and/or new RS.In addition, removing in DRS
Outside PSS and SSS, CRS must tie up at least one symbol, NZP CSI-RS and new RS can be without.
5th, further, since PSS/SSS of the prior art is sent in fixed subframe, it is possible to realize that frame is same
Step.And the method PSS/SSS can send in any subframe, so in order to realize frame synchronization, The present invention gives table
Show the method that subframe is numbered：I.e. according to different fill methods, with reference to the difference of SSS, terminal can be made to determine that DRS's is true
Real numbering, detailed process is as follows：
0#~4#subframe is with the SSS of traditional No. subframe#0；5#~9#subframe is with traditional
The SSS of No. subframe#5, such subframe is just divided into two groups, next according to different fill methods, son in differentiation group
Frame number.
Because there are 5 subframe per group, 5 kinds of fill methods are at least wanted.And the PSS and SSS in DRS occupies two
Individual symbol, and the CRS in DRS must tie up a symbol：
1) for FDD frame structures：
As shown in figure 13, for during FDD (by taking the #5 subframes that DRS is taken in FDD frame structures as an example), because CSI-RS
The sign bit that may be taken is equipped with symbol#5 and #6, #9 and 10#5,12# and #13 (as shown in Figure 15 and Figure 16, wherein, Figure 15
The sent time-frequency location of CSI-RS when showing two transmission antennas (i.e. antenna port is 15,16)；Figure 16 shows four
The sent time-frequency location of CSI-RS during transmission antenna (i.e. antenna port is 15,16,17,18).In Figure 15 and Figure 16, horizontal seat
Mark symbol index represent the true numbering of symbol, and R15,16Represent CSI-RS to transmit at antenna port 15 and 16, and
R17,18Represent CSI-RS to transmit at antenna port 17 and 18, the numbering in the R upper right corner represents the sent time-frequency location of CSI-RS
Numbering.Vertical coordinate subcarrier index represent the label i.e. position of subcarrier of subcarrier), and symbol#5, #6 quilt
PSS/SSS is occupied, thus CSI-RS select take symbol#9 and #10, do not select take symbol#12 and #13 be in order to
Ensure most short DRS length.So one DRS occasion (DRS can send position) is occupied in 1 subframe
Symbol#5~#10, altogether 6 symbol.
Symbol#5, #6, #7 are fixed to SSS, PSS, CRS.Symbol#8 with CRS fill, with antenna number be 4 when feelings
Condition is the same, does not indicate that antenna number for 4, when antenna number is 2 it is also possible that.Symbol#9 and #10 is filled by CSI-RS, no
The sub-carrier positions being located with the CSI-RS of resource configuration (resource structures) are different, so as to represent difference
Subframe numbering.Here the situation that can select to be only taken up in 12 subcarriers 1 subcarrier is (this equivalent to there is 12 kinds
CSI-RS can indicate 12 kinds of subframe numberings, as shown in figure 15：CSI-RS time-frequency locations during two transmission antennas), also may be used
Can be uniformly distributed in select 12 subcarriers take two subcarriers situation it is (this equivalent to there is 6 kinds of CSI-RS to indicate 6
Subframe numberings are planted, as shown in figure 16：CSI-RS time-frequency locations during four transmission antennas).
2) for tdd frame structure (by taking #5, #6 subframe that DRS is taken in FDD frame structures as an example)：
When as shown in figure 14, for TDD, because the sign bit that CSI-RS may take is equipped with symbol#5 and #6, #
9 and #10, #12 and #13 (as shown in Figure 15 and Figure 16), and symbol#13, #2 are occupied by PSS/SSS, so CSI-RS choosings
It is to ensure that the data of the resource configuration of CSI-RS are more than 5 to select occupancy symbol#9 and #10.So
One DRS occasion occupies the 0~2 of symbol#9~13 in 1 subframe and lower 1 subframe, and altogether 8
Individual symbol.
It is of course also possible to select for CSI-RS to be placed on new symbol positions, such as the above symbol#11 of subframe
And #12, or the symbol#3 and #4 of subframe below, so, DRS can just only take up 6 symbol.
In addition, visible from the above analysis, because the DRS of TDD occupies two subframe, and what CSI-RS was indicated
No. subframe be CSI-RS be located subframe numbering (numbering of i.e. preposition subframe), as shown in figure 14.
In addition, if before each DRS sends, CCA detects the transmission position that down channel is idle, without arriving DRS,
Then for busy channel, reservation signal (preserved signal) or initial can also be sent before DRS
Signal (initial signal) or CRS or CSI-RS, but the temporal summation for sending these signals obtains restricted, such as less than M
Symbol, this can be avoided channel reservation holding time long so that miscellaneous equipment cannot be robbed and account for channel.
6th, it is described below how base station notifies UE, the transmission parameter of DRS：
RRC signaling notifies the cycle of DMTC, offset (i.e. the other biasing of sub-frame level)；
RRC signaling notifies the time span for needing to detect DRS in DMTC, 1~5ms；
RRC signaling notifies that the position number of DRS can be sent in DMTC, and 1~5, and the other position offset of symbol level is
The other time offset of symbol level (such as symbol#5), the number of symbols (such as 6) that each DRS takes.
RRC signaling notifies that the corresponding different subframe of different CSI-RS resource configuration are compiled
Number.As shown in table 1 (i.e. the first subframe number reference table), with reference to Figure 16：RRC signaling includes following 4 row.1st row mark CSI-
The numbering of the resource configuration of RS, directly the index (label) in the R upper right corner is obtained numbering from figure, simply
Individual representation, but numbering can be represented, for example：Index is on #5 and #11 sub-carriers of 1 expression in per 12 subcarriers
The CSI-RS for sending non-zero power is that the CSI-RS of non-zero power takes #5 and #11 sub-carriers, and other positions not send
CSI-RS, and number be 6 expressions per #4 the and #10 sub-carriers in 12 subcarriers on send non-zero power CSI-RS, and
, not send CSI-RS, the rest may be inferred for other positions.Secondary series, is that the transmission correspondence of non-zero power CSI-RS of the position is represented
Group in subframe numberings, only represent 0~4；3rd row are the types of SSS in DRS, if having said that subframe is 0 before
~4, then the SSS types i.e. first kind sent when using subframe#0, the SSS classes sent when otherwise using subframe#5
Type is Second Type.4th row are that the subframe numberings that the final DRS be given with reference to secondary series and the 3rd row takes are i.e. true
Real to number, its process is:SSS numberings are that 1 secondary series subframe numberings add 5, draw final subframe numberings, i.e.,
It is the 4th row.
Table 1
By above signaling, UE can be with blind check repeatedly, and how many is notified of in DMTC in RRC signaling can send DRS's
Position, then UE will most blind check how many times, until detecting till sending DRS.Such as：Base station notifies 5 in terminal D MTC
Each subframe in individual subframe has 1 fixed position to send DRS, then to be accomplished by blind check most 5 times but actual for UE
Above some can send position because Channel Detection is done, and base station does not send DRS.
Therefore, in order to further reduce UE blind check number of times, base station can send instruction letter when really have sent DRS
Make to UE, such as：By PDCCH (physical Downlink Control Channel Physical Downlink Control Channel) or
EPDCCH (Enhanced Physical Downlink Control Channel strengthen downlink physical control channel) is being authorized
DCI (Downlink Control Information, Downlink Control Information) is sent on frequency spectrum or unlicensed spectrum and indicates letter
Make to UE, then UE has just known that the position have sent DRS really.
The resource configuration of the NZP CSI-RS that the same subframe of neighbor cell sends are best
It is different.It is easy to using NZP CSI-RS measurement signal intensity, if same subframe is in same resource
If configuration sends, NZP CSI-RS will be disturbed by adjacent cell during measurement, if adjacent cell is in other symbol
Number position sends, i.e., if same character position is empty, then testing result can be relatively more accurate.
7th, the behavior of UE is described below：
UE receives RRC signaling, obtains the cycle of DMTC, offset；So as to navigate to which subframe DMTC is at.
UE receives RRC signaling, obtains the time span for needing to detect DRS in DMTC, and 1~5ms at most need so as to recognize
Detect how many times DRS.
UE receives RRC signaling, and obtaining can send the position number of DRS in DMTC, and 1~5, and the other position of symbol level
Offset (such as symbol#5), the number of symbols (such as 6) that each DRS takes.So as to recognize that each DRS sends position tool
Which symbol bodies includes.
UE receives RRC signaling, obtains different CSI-RS resource configuration corresponding different
Subframe is numbered.The positional information of the CSI-RS by detecting, and the type of SSS, it is final drawing with reference to table 1
Subframe is numbered.Detailed process is as follows：RRC signaling includes following 4 row.The resource of the 1st row mark CSI-RS
The numbering of configuration, numbers the index directly from the R upper right corner in Figure 15 and Figure 16 and obtains, simply individual representation,
But numbering can be represented.For example：Index is to send non-zero power on #5 and #11 sub-carriers of 1 expression in per 12 subcarriers
CSI-RS be that the CSI-RS of non-zero power takes #5 and #11 sub-carriers, and other positions not send CSI-RS, and number
Represent the CSI-RS that non-zero power is sent on per #4 the and #10 sub-carriers in 12 subcarriers, and other positions not send out for 6
CSI-RS is sent, the rest may be inferred.Secondary series, is subframe in the corresponding group for representing of transmission of non-zero power CSI-RS of the position
Numbering, only represents 0~4；3rd row are the types of SSS in DRS, if having said that subframe is 0~4 before, are used
The SSS types sent during subframe#0, the SSS types sent when otherwise using subframe#5.4th row are to combine second
The subframe that the final DRS that row and the 3rd row are given takes numbers i.e. true numbering, and its process is:SSS numberings are the of 1
Two row subframe numberings add 5, draw final subframe numberings, are the 4th row.
8th, the difference of the resource configuration of the such as CSI-RS of the filling mode in DRS can be provided for mark
Different operators, the secondary series and the 4th row subframe numberings that identification method can change into operator in table 1 can (such as
Shown in table 2, table 2 represents first operator's reference table).Or using the different subframe of the scrambling code identification of NZP CSI-RS
(as shown in table 4, table 4 is represented for numbering (as shown in table 3, table 3 represents the second subframe number reference table) and different operators
Second operator's reference table), such as scrambler is that (E-UTRAN Cell Global Identifier, E-UTRAN cells are global for ECGI
Identifier), wherein, E-UTRAN (Evolved UMTS Terrestrial Radio Access Network, the UMTS of evolution
Land radio access web), i.e. mobile communication wireless network in LTE.Because ECGI is exactly PLMN ID (Public Land
Mobile Network Identity, public land mobile network mark)+PCI (physical-layer Cell
Identity, physical-layer cell identifier), thus can also directly the resource configuration of NZP CSI-RS or
Scrambler shows PLMN ID.So, operator identifier is judged when CCA is detected if necessary to terminal, so as to by same fortune
Battalion business signal power remove after again with threshold (power threshold), then CCA when grow comprising whole symbol, and
It is limited to the symbol for sending operator identifier.Or will send operator identifier signal send particle size reduction, so as to compared with
Operator identifier can be also detected in the short CCA times.
Table 2
Table 2 and Figure 16 can be seen that CSI-RS time-frequency locations during four transmission antenna using symbol#9 and #10, knot
SSS types are closed, 12 kinds of operators can be at most indicated；If using symbol#9 and #10 two transmission antennas when CSI-RS
Time-frequency location, with reference to SSS types, then can at most indicate 24 kinds of operators.In addition, Tables 1 and 2 can also combine,
It is exactly sub-carrier positions (for example, the R in Figure 15 that CSI-RS time-frequency locations take1 15,16Represent that CSI-RS is taken in time-frequency
Numbering is 11 the 12nd subcarrier, and is sent at antenna end slogan 15,16, the like) and SSS type, combine
To indicate that subframe is numbered and operator.
Table 3
Shown in table 3, because only needing to indicate 10 subframe numberings, and two groups can be divided into by SSS types, so
5 kinds of subframe numberings in instruction group are only needed to, then 5 groups of different scramblers.
Table 4
Table 4 is as can be seen that using 5 kinds of scramblers, with reference to SSS types, can at most indicate 10 kinds of operators；Refer to if desired
Show more kinds of operators, then increase scrambler number.In addition, table 3 and table 4 can also combine, that is, CSI-RS is disturbed
The type of code and SSS, joins together to indicate subframe numberings and operator.
Or above 4 table combination in any are got up, the type of the time-frequency location, scrambler and SSS of CSI-RS joins together to refer to
Show that subframe is numbered and operator.
Finally, the attribute information of the composition of DRS is different can also identify different No. subframe (as shown in table 5, table 5
Represent the 3rd subframe number reference table) or operator's (as shown in table 6, table 6 represents the 3rd operator's reference table), such as
FDD is made up of various DRS's：
Composition 1：Comprising symbol#4 (filling CRS), #5 (filling SSS), #6 (filling PSS)；
Composition 2：Comprising symbol#5 (filling SSS), #6 (filling PSS), #7 (filling CRS)；
Composition 3：Comprising symbol#4 (filling CRS), #5 (filling SSS), #6 (filling PSS), 7 (filling CRS)；
Composition 4：Comprising symbol#5 (filling SSS), #6 (filling PSS), 7 (filling CRS), #8 (filling CRS), #9 (is filled out
Fill NZP CSI-RS), 10 (filling NZP CSI-RS)；
Composition 5：Comprising symbol#4 (filling CRS), #5 (filling SSS), #6 (filling PSS), #7 (filling CRS), #8 (is filled out
Fill CRS), #9 (filling NZP CSI-RS), #10 (filling NZP CSI-RS)；
Composition 6：Comprising symbol#4 (filling CRS), #5 (filling SSS), #6 (filling PSS), #7 (filling CRS), #8 (is filled out
Fill CRS), #9 (filling NZP CSI-RS), #10 (NZP CSI-RS fillings), #11 (filling CRS)；
Composition 7：Comprising symbol#5 (filling SSS), #6 (filling PSS), #7 (filling CRS), #8 (filling CRS), #9 (is filled out
Fill NZP CSI-RS), #10 (filling NZPCSI-RS), #11 (filling CRS).
And its signaling is similar with UE behaviors, DRS composition attribute information differences will indicate different No. subframe.
