Description

Collocation method, configuration system, equipment, method of reseptance, reception system and terminal
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 Step.

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.
Table 5
Table 5 provides different according to the attribute information of DRS compositions, such as the number of symbols for taking, and position and each symbol are filled out The content filled is different, indicates that subframe is numbered with reference to the type of SSS.
Table 6
Table 6 is different according to the attribute information that DRS is constituted, such as the number of symbols for taking, position is filled with each symbol Content is different, and with reference to the type of SSS operator is indicated, if it is desired to indicate more operators, then using more different category Property information.
The content of table 2- tables 6 can be notified to terminal as table 1 by RRC signaling, the behavior of terminal also with reception To table 1 RRC signaling when it is the same, determine that subframe is numbered and/or operator by the information that receives and reference table.
