Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is a part of embodiment of the invention, rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made belongs to the scope of protection of the invention.
Technical scheme, can apply to various communication systems, for example:Global system for mobile communications(GSM, Global System of Mobile communication), CDMA(CDMA, Code Division Multiple Access) system, WCDMA(WCDMA, Wideband Code Division Multiple Access Wireless), GPRS (GPRS, General Packet Radio Service), Long Term Evolution (LTE, Long Term Evolution) etc..

Base station, can be the base station in GSM or CDMA(BTS, Base Transceiver Station), can also be the base station in WCDMA(), NodeB it can also be the evolved base station in LTE(ENB or e-NodeB, evolutional Node B), the present invention is not limited, but for convenience of description, following embodiments are illustrated by taking Node B as an example.
In addition, the terms " system " and " network " are often used interchangeably herein.The terms " and/or ", only a kind of incidence relation for describing affiliated partner, represents there may be three kinds of relations, for example, A and/or B, can be represented:Individualism A, while there is A and B, these three situations of individualism B.In addition, character "/" herein, typically represent forward-backward correlation object be it is a kind of " or " relation.
In LTE system, in time domain, a radio frames include 10 subframes;On frequency domain, a load Ripple includes multiple PRB pairs.Base station is scheduled in units of RB pairs, and a RB accounts for 12 OFDMs to accounting in time in a subframe, frequency(OFDM, Orthogonal Frequency Division Multiplexing) subcarrier.For normal cyclic prefix, a subframe includes 14 OFDM symbols(Symbol), for extended cyclic prefix, a subframe includes 12 OFDM symbols.Wherein, some subcarrier on some symbol is minimum resource units, is called resource unit (Resource Element).
Figure 1A is the schematic diagram of channel on the LTE carrier waves of backward compatibility type and signal.Specifically, synchronizing signal 11 is located at subframe 0 and subframe 5, and the cycle is 5 subframes.PBCH 12 carries information of primary significance block(MIB, Master Information Block) and System information block(SIB, System Information Block), wherein MIB is located at subframe 0, and the cycle is a radio frames;SIB can be divided into SIB1 to SIB13 again, and the wherein SIB1 transmission cycle is 20ms, and positioned at the subframe 5 of even number radio frames, other SIB, such as SIB2 to SIB13 do not have regular time, but are sent in specific time window.CRS is used to be required for sending in synchronous time-frequency essence, data demodulation, channel condition information measurement and RRM measurement etc., each subframe and each RB.PDCCH is located in the search space of control area 13, PDCCH control areas 13 are located at the preceding n symbol of a subframe in time domain, n is one of 1-4 natural number, the bandwidth of whole carrier wave is accounted on frequency domain, wherein the PDCCH sent breaks up whole descending carrier bandwidth to obtain frequency diversity gain by interweaving.
For the LTE system of Rel-10 versions, UE is receiving synchronizing signal, PBCH, SIB, during the subframe of the paging of RACH response messages and cell-level, is that now CSI-RS is also configured without giving the UE before RRC foundation.Subframe where considering further that the paging of synchronizing signal, PBCH, SIB1 and cell-level is all fixed or specific, therefore UE is when receiving the subframe of paging of synchronizing signal, PBCH, SIB1 and cell-level, need to assume that CSI-RS is not present, correspondingly, base station will not also send CSI-RS in these subframes, can so avoid receptions of the CSI-RS to synchronizing signal, PBCH, SIB 1 and paging from interfering.Correspondence CSI-RS resource unit is with 14 marks in figure.
But, for the LTE system of Rel-10 versions, UE is receiving RACH response messages and the SIB in addition to SIB1, for example during at least one of SIB2 to SIB13, the situation to the UE is also configured without there is also now CSI-RS, therefore UE is when detecting other SIB of the PDSCH and detection of RACH responses in addition to SIB1 PDSCH or to assume that CSI-RS is not present.But, base station is when these information are sent, if not in the subframe where the paging of synchronizing signal, PBCH, SIB1 and cell-level, so base station can send CSI-RS, that is, Physical Downlink Shared Channel (Physical Downlink Shared Channels of the UE in detection RACH responses PDSCH) and other SIBs of the detection in addition to SIB 1 PDSCH when may be disturbed by CSI-RS.The reason for causing this problem be, RACH is responded and other SIB in addition to SIB 1 are unfixed delivery times, but in respective transmission subframe window, so if CSI-RS can not all be sent by limiting these subframes, finally CSI-RS may be caused can not to send completely, therefore the program is unacceptable.
Solve the above problems, one scheme is that base station is above- mentioned information (other SIBs of the PDSCH and detection that RACH is responded in addition to SIB 1 PDSCH) scheduling in the subframe where the paging of synchronizing signal, PBCH, SIB 1 and cell-level.For example, it is assumed that the paging subframe of current area is subframe 9, consider further that subframe 0,5 will carry PBCH and synchronizing signal, therefore can be above- mentioned information scheduling in subframe 0,5,9, but problem is so to introduce scheduling limitation.Otherwise, still it may be disturbed when UE is detected by CSI-RS.But in view of being all the interference to PDSCH, base station can send these PDSCH with more conservative modulation coding mode, to reduce the receptivity loss that CSI-RS interference fringes come.
Figure 1B is the schematic diagram of channel on the LTE carrier waves of new wave-carring type and signal.Specifically, PRB pair set can be distributed for ePDCCH, the collection is closed comprising ePDCCH search spaces 15, to supply UE to detect ePDCCH in the search space.In the LTE system of the versions of Rel- 11, the ePDCCH specific search spaces of UE are introduced(EUSS), UE will get around CSI-RS in the ePDCCH in receiving the specific search spaces of UE by solving rate-matched.Problem is that CSI-RS is that, by the proprietary signal deployments of UE, different UE can configure different CSI-RS patterns, therefore above-mentioned detection ePDCCH still may canI enters CSI-RS influence, it is possible to which other UE CSI-RS is received as ePDCCH.This problem can be solved by the realization of base station, and the CSI-RS set for for example allowing the UE under a base station to see is identical.Specifically, for example it is allocated to UE1 non-zero power CSI-RS resource location, the CSI-RS of zero energy is configured to for UE2, set of so UE1 with the CSI-RS that UE2 sees always is consistent, CSI-RS is also just not present the ePDCCH receptions in the specific search spaces of UE are interfered.
In the LTE system in the versions of Rel- 12 or future, ePDCCH public search space (eCSS) can be introduced.It is especially considering that new wave-carring type(NCT introducing), due to can the control area without backward compatibility, the public search space of backward compatibility is not present, so if new wave-carring type will be individually present, one natural scheme is the public search space for introducing ePDCCH, with the function of the public search space of the forward and backward compatibility of offer.
EPDCCH public search space is introduced, still there can be the problem of CSI-RS is related, and And problem than above-mentioned Rel-10 and Rel-11 the problem of it is more serious.Specifically include following at least one situation.
1) the Downlink Control Information 3/3A of original group Power Control is sent in the control area of backward compatibility, and CSI-RS is not had in control area, therefore 3/3A is not influenceed by CSI-RS, but, ePDCCH public search space can be in units of PRB pair, therefore can be influenceed by CSI-RS.
2) in following network design, can largely dispose can also dispose some or substantial amounts of Microcell in the coverage of the macrocell of heterogeneous network, i.e., one, and the macrocell and these Microcells may share an identical Physical Cell Identifier.Under this scene, the UE numbers serviced in the range of macrocell can be more than UE numbers in conventional cell, system so before the transmission Capacity Ratio of CCCH is big, such as RACH is responded, therefore RACH response schedulings can be evaded in the subframe where the paging of PBCH, SIB1 and cell-level the interference that CSI-RS is brought, but scheduling limitation is larger;Scheduling limitation can not also be considered, but can be disturbed by CSI-RS, but can be also interfered in itself for ePDCCH, and only PDSCH can be interfered in the system of Rel-10 and Rel-11 versions.
3) CSI-RS interference is dispatched for the ePDCCH in the specific search spaces of UE, can be solved by the implementation method of base station, therefore the specific search spaces of UE(EUSS) configured when UE enters connected state or after entrance connected state;And for ePDCCH public search space(ECSS), may be without the resource that CSI-RS is configured for UE, that is UE does not know the CSI-RS configuration patterns in current area, therefore except scheduling mentioned above is limited, the interference that this CSI-RS is brought is can not to be solved by the implementation method of base station.
In summary, public search space of the above-mentioned CSI-RS relevant issues in ePDCCH(ECSS after) introducing, due to scheduling limitation aggravation, down control channel is interfered in itself;The reason for sunset fore-telling except dispatching limitation, method solution that this interference can not be realized by base station etc., cause this problem more serious than Rel- 10 before and the versions of Rel- 11 intersystem problem.
Therefore, the embodiment of the present invention proposes the method for solving how to send CSI-RS on NCT to reduce interference, resource impact problems of the especially CSI-RS in eCSS regions.Wherein, for convenience of explanation, can be public CSI-RS and special CSI-RS CSI-RS points for different purposes.Wherein, special CSI-RS is identical with CSI-RS of the prior art, namely refer to the CSI-RS that UE is allocated to by proprietary RRC signaling in existing system, channel and interferometry are carried out for UE, and to get around the special CSI-RS during UE reception dedicated channels, i.e., rate-matched is carried out to special CSI-RS.Above-mentioned dedicated channel can be PDSCH and the UE specific PDCCH or EPDCCH for carrying the specific downlink datas of UE.Public CSI-RS is defined in the embodiment of the present invention, to refer exclusively to UE and receiving public letter The CSI-RS got around is needed during road, the common signal channel can include at least one of information such as the enhanced physical mixed automatic re-transmission indicating channel (EPHICH, Enhanced Physical Hybrid Automatic Repeat Request Indicator Channel) of the public multi-user association codings of public EPDCCH carried in Physical Broadcast Channel, eCSS, the PDSCH of above-mentioned public EPDCCH scheduling.Herein, other reference signals similar with CSI-RS can imitate this processing.
That is mentioned in the embodiment of the present invention gets around, and sends and operates for base station side, by the information after coding toward when mapping on physical resource, can skip above-mentioned public or special CSI-RS;Brought drill to an end work for UE side joints, to sent on above-mentioned physical resource above- mentioned information demapping when, above-mentioned public or special CSI-RS can be skipped.
Special CSI-RS includes non-zero power CSI-RS and zero energy CSI-RS.Wherein, non-zero power
CSI-RS-as be used for measure channel.Zero energy CSI-RS has two kinds of application methods, a kind of application method is, the sets of resource units for the non-zero power CSI-RS that cell 1 is sent is configurable to zero energy CSI-RS for cell 2, so ensures the accuracy for the UE non-zero power CSI-RS measurement channels that cell 1 is serviced;Another application method is to be used to measure interference, and now this zero energy CSI-RS can be called interferometry resource.
Except eCSS introducing, it is also conceivable to the extension of CSI-RS on NCT.In existing LTE systems, the subframe that CSI-RS is sent is limited, such as CSI-RS is in transmission SIB1 mentioned above and paging(Paging it cannot be sent in subframe), and if the subframe that synchronizing signal or PBCH are sent conflicts with CSI-RS, CSI-RS is also to send.Future, the evolution of system can depend on NCT, and the CRS on NCT will be reduced or even be cancelled, CSI-RS is so only depended at least in terms of CSI measurements, and other CRS function, such as RRM (RRM, Radio Resource Management) measurement, synchronous etc. may also be extended to by using CSI-RS to solve.Therefore, effects of the CSI-RS during the system evolved in LTE future can be increasing, and the CSI-RS in current system is limited.The scheme of the embodiment of the present invention can also accomplish the extension of CSI-RS.
Fig. 2 is the schematic flow diagram of method 20 that receives of information of the embodiment of the present invention, including following interior paddy.

Next, further illustrating the method for the embodiment of the present invention by base station and UE interaction.Fig. 4 is the schematic diagram of the information exchange of the embodiment of the present invention.
EPDCCH public search space is introduced in the embodiment of the present invention( eCSS ).For convenience of description, CSI-RS of the prior art is referred to as special CSI-RS.In addition, another CSI-RS is also defined, that is, public CSI-RS.First configuration information is used for the first resource unit set for indicating the transmission public CSI-RS.
Fig. 5 is the schematic diagram of CSI-RS pattern in the prior art on a PRB pair.Specifically, in current LTE system, there are a variety of CSI-RS patterns.Shown in Fig. 5 be the digitized representation in the CSI-RS under eight antenna configurations, Fig. 5 be each eight antenna configuration label, other antenna configurations are also not excluded for.The first resource unit set of public CSI-RS in the embodiment of the present invention, with 51 marks, can be the configuration under some eight antenna configuration, such as the corresponding sets of resource units of the CSI-RS marked as 0, current other configurations are also not excluded for.For convenience of description, also identify CRS resource unit 52 in Fig. 5 with different fillings simultaneously, and UERS resource unit 53.In addition, first configuration information can also include other information, such as cycle, subframe position, PRB positions, zero energy CSI-RS configurations and the non-zero power CSI-RS configurations of CSI-RS, etc..
S410, UE obtain the first configuration information, and first configuration information is used for the first resource unit set for indicating the public CSI-RS of transmission.
First resource unit set can include one or more resource units.
In one embodiment, the first configuration information of the public CSI-RS be it is pre-configured, this it is pre-configured can standard pre-define.So, base station and UE both sides do not need Signalling exchange just to know the first configuration information in advance.For example, the eight antenna configuration CSI-RS marked as 0 in Fig. 5 Sets of resource units be exactly first resource unit set, the configuration of other antenna ports is similar with the configuration of other labels, is also not excluded for.In addition, the frequency domain width of the public CSI-RS, that is, the PRB pair taken, can be Whole frequency bands, that is, take whole PRB pairs on current carrier;Can also take fractional bandwidth, such as in the 6 of current carrier center PRB pair, etc..Subframe shared by the public CSI-RS can be whole subframes, or UE needs to detect whole subframes of common signal channel;Can also be part subframe, for example the public CSI-RS has certain cycle, such as using 5 subframes as cycle, etc..
In another embodiment, the UE obtains the first configuration information of the public CSI-RS by synchronizing signal and/or broadcast channel.Specifically, it can be indicated using the bit in the cell ID and/or Physical Broadcast Channel carried in synchronizing signal or scrambler, that is UE needs to read synchronizing signal, obtain cell ID therein, and/or read bit or scrambler in Physical Broadcast Channel to obtain above-mentioned configuration information, other broadcast channels such as SIB indicates also to be not excluded for.So that the bit of Physical Broadcast Channel is indicated as an example, or by taking eight antenna configurations in Fig. 5 as an example, it can be seen that there is the CSI-RS configurations of 5 kind of eight antenna, the first resource unit set which eight antenna configuration is public CSI-RS so can be specifically indicated with 3 bits in Physical Broadcast Channel, other antenna configurations are also not excluded for;Or, so that cell ID is indicated as an example, for example modulo operation can be carried out to above-mentioned 5 eight antenna CSI-RS configurations with Physical Cell Identifier, such as Physical Cell Identifier is 11, so ll mod 5 result is 1, it can so obtain and be configured to 1 eight antenna CSI-RS and be configured to public CSI-RS first resource unit set, other certain similar mathematical operations are also not excluded for;Or, broadcast channel and synchronizing signal joint instructions can be used, specific method as described above, is repeated no more.
In another embodiment, public CSI-RS sets of resource units can also and frame number, subframe numbers or timeslot number be associated, while this method can also be combined to indicate with above-mentioned synchronizing signal and/or broadcast channel.Specifically, still being configured by the CSI-RS of above-mentioned 5 eight antennas in Fig. 5 exemplified by being associated by subframe numbers, subframe numbers 0 and 1 can correspond to CSI-RS with setting to 0, subframe numbers 2 and 3 can correspond to CSI-RS configurations 1, etc., certainly, other correlating methods are also not excluded for.The beneficial effect of the embodiment of the present invention is, the efficiency of randomization can be accomplished, such as part subframe, public CSI-RS can be identical with a part of UE CSI-RS, in other subframe, public CSI-RS can be identical with another part UE CSI-RS, further, it is also possible to CSI-RS configuration randomizations and interference coordination between accomplishing different districts.
Optionally, as a kind of embodiment, above-mentioned public CSI-RS is bypassed common signal channel when sending and receiving, so as to avoid interference.Further, it is also possible to carry the special CSI-RS of particular UE configuration information using public CSI-RS first resource unit.Specifically, public CSI-RS can be provided Some of source or whole CSI-RS are configured to some UE or some UE special CSI-RS, and these particular UEs need to receive the further instruction of base station, such as the proprietary signalings of RRC of the prior art are to receive special CSI-RS configuration information.So can be with efficent use of resources.
Common signal channel can include the first control channel and/or the first data channel, first control channel is used for schedule system information block, paging information, Stochastic accessing response message, at least one of group power control information, first data channel is used at least one of bearing system block of information, paging information, Stochastic accessing response message.First control channel can be PDCCH or ePDCCH, and the first data channel can be Physical Downlink Shared Channel (PDSCH, Physical Downlink Shared Channel) etc..These common signal channels can be sent for multiple UE, i.e. multiple UE are required for control or the data channel received, this multiple UE can not only include the UE of RRC connected states, can also include carrying out RRC Idle state UE and be initially accessed and be also introduced into the UE of RRC connected states.Particularly, the UE for being introduced into connected state is also required to read above-mentioned common signal channel, such as system information block SIB, and these UE do not obtain RRC signaling now, the CSI-RS configurations of RRC signaling configuration can not be obtained, therefore above-mentioned public CSI-RS configuration can only be predefined, or broadcast channel notifies.
First resource can be in public search space, and the public search space can be ePDCCH public search space (eCSS).For example, there is multiple candidate ePDCCH resource in public search space, definition such as in PDCCH public search space, it is 4 control channel unit (CCE for polymerization grade, Control Channel Element) for, there are 4 candidate resources, for polymerization grade is 8, there are two candidate resources, this rule can be moved in ePDCCH mechanism, or can be using other polymerization grades and corresponding candidate resource division methods for ePDCCH, but method is all similar, any restriction is not done.So, the first resource is exactly a candidate resource of the ePDCCH in ePDCCH public search space.Or, the first resource can also be for UE detect Physical Broadcast Channel resource, or other broadcast channels resource.
S415, UE determine the first resource of transmission common signal channel according to the first configuration information, and the first resource includes the first resource unit set.
Corresponding, base station side performs herein below.
S420, base station determines the first configuration information, and first configuration information is used for the first resource unit set for indicating the public CSI-RS of transmission.
Optionally, as different embodiments, the base station obtains pre-configured public CSI-RS configuration information;The configuring condition of the special CSI-RS for the UE that base station passes through this cell determines public CSI-RS configuration information, such as preferentially the special CSI-RS of non-zero power can be configured public In CSI-RS resource;Or base station is also conceivable to CSI-RS configuring conditions, such as interference coordination under the base station of peripheral cell, to avoid the CSI-RS between base station.
Optionally, as different embodiments, the base station sends the configuration information of the public CSI-RS by synchronizing signal and/or broadcast channel to UE;Or the base station sends the configuration information of the public CSI-RS by way of public CSI-RS configuration information is associated with frame number, subframe numbers or timeslot number to UE.
S425, base station determines the first resource of transmission common signal channel according to the first configuration information, and the first resource includes the first resource unit set.
S430, base station gets around the first resource unit set on the first resource and sends the common signal channel.
S435, UE get around the first resource unit set on the first resource and receive the common signal channel.
That is, UE it will be assumed that what is sent at the first resource unit set of the public CSI-RS in the first resource of above-mentioned common signal channel is not the information of above-mentioned common signal channel, that is when UE detects common signal channel on first resource, above-mentioned public CSI-RS first resource unit set can be got around.So do, it can ensure that receptions of the CSI-RS that may be sent on public CSI-RS first resource unit set to above-mentioned common signal channel is not interfered with, the receptivity of common signal channel is improved, can ensure that the CSI-RS measurements on public CSI-RS first resource unit set are unaffected again.Specifically, common signal channel is also received due to being not in the UE of connected state, and these UE are the CSI-RS configurations in system of not knowing when being not in connected state, i.e., other UE CSI-RS is there may exist on first resource;Now, if not introducing above-mentioned public CSI-RS, so these UE for being not in connected state can receive the CSI-RS actually sent in system as common signal channel when receiving common signal channel, and the CSI-RS interference brought can cause the receptivity of common signal channel to decline.And configured by configuring pre-configured or broadcast channel instruction a public CSI-RS, these UE for being not in connected state can be allowd to get this public CSI-RS configuration, and base station can be allocated to the CSI-RS in this public CSI-RS configuration the UE that connected state is in current area, if current area need not exclude CSI-RS and give connected state UE, then CSI-RS can not be allocated to connected state UE in this public CSI-RS configuration, in any case, UE can get around the sets of resource units under this public CSI-RS configuration in reception common signal channel.So, when the CSI-RS in this public CSI-RS configuration is allocated to the connected state UE in current area by base station, all UE receive the interference that common signal channel is brought all without the CSI-RS received in this public CSI-RS configuration, and the UE of connected state can be normally using the CSI-RS in this public CSI-RS configuration Do CSI measurements.
S440, UE obtain the second configuration information, and the second configuration information is used for the Secondary resource unit set for indicating the special CSI-RS of transmission.
S445, UE determine the Secondary resource of transmission dedicated channel according to the second configuration information, and Secondary resource includes the Secondary resource unit set.
Content in special CSI-RS the second configuration information, such as resource unit, antenna port etc. is all similar with the first configuration information, repeats no more.Unlike, UE obtains the configuration of the special CSI-RS by the proprietary signalings of RRC, therefore the UE is RRC connected states UE.And the public CSI-RS and special CSI-RS sets of resource units can be separate configurations with identical or different.Optionally, the first resource, which includes the Secondary resource unit set and/or the Secondary resource, includes the first resource unit set.
Corresponding, base station side performs herein below.
S450, base station determines the second configuration information, and second configuration information is used for the Secondary resource unit set for indicating the special CSI-RS of transmission.
S455, base station determines the Secondary resource of transmission dedicated channel according to the second configuration information, and the Secondary resource includes the Secondary resource unit set.
S460, base station gets around the Secondary resource unit set on the Secondary resource and sends the dedicated channel.
S465, UE get around the Secondary resource unit set on the Secondary resource and receive the dedicated channel.
Connected state UE can also receive the downstream data channel of dedicated channel, such as the PDCCH or ePDCCH of C-RNTI scramblings, and above-mentioned special PDCCH/ePDCCH scheduling.By taking special ePDCCH as an example, the ePDCCH-as be located at the UE the specific search spaces of UE in, in addition, some are used for the ePDCCH of the specific format of rollback scheduling, such as form 0 and form 1A ePDCCH, it can be located in the specific search spaces of UE of the UE and/or public search space, the Secondary resource can just turn into the specific search spaces of above-mentioned UE and/or the candidate resource of the ePDCCH in public search space, the connotation of candidate resource is identical with above-mentioned first resource, repeats no more.
UE gets around Secondary resource unit set on Secondary resource and receives the dedicated channel, that is the UE is when receiving dedicated channel, for CSI-RS, only need to get around the Secondary resource unit set by the proprietary signal deployments of RRC to the UE, above-mentioned first resource unit set need not be got around, because first resource unit set is served only for what is got around when UE receives common signal channel. Fig. 6 A be the embodiment of the present invention when receiving common signal channel to the schematic diagram of CSI-RS hypothesis.In one embodiment, as shown in Figure 6A, the first resource 61 can include the Secondary resource unit set 62, it is clear that, first resource 61 and Secondary resource 63 are overlapping completely or partially, because all including Secondary resource unit set 62.Now, the UE is not used as the hypothesis for the reference signal for needing to get around when receiving the common signal channel on the first resource 61 using the Secondary resource unit set 62, i.e. above-mentioned Secondary resource unit set 62 is inoperative for receiving common signal channel, now detects and gets around first resource unit set 64 during common signal channel.This is unified behavior for connected state UE and disconnected state UE.And for the UE of connected state, if Secondary resource unit set 62 is not included by first resource unit set 64 and first resource 61 includes the Secondary resource unit set 62, then the UE can do CSI measurements with being allocated to the CSI-RS of oneself on above-mentioned Secondary resource unit set 62 with unfavorable, because now base station is when sending common signal channel, it is possible to the CSI-RS of the UE is not sent on above-mentioned Secondary resource unit set 62;Or the UE only does CSI measurements using being allocated to the zero energy CSI-RS of oneself on above-mentioned Secondary resource unit set 62, because base station may send zero energy CSI-RS on above-mentioned Secondary resource unit set 62, therefore zero energy CSI-RS is little for the influence of common signal channel receptivity, and zero energy means that the transmit power of CSI-RS positions is 0.Or, if the first resource unit set 64 does not include the Secondary resource unit set 62, and the first resource 61 include the Secondary resource unit set 62 when, the UE does not expect to receive the special CSI-RS or special CSI-RS of non-zero power on the Secondary resource unit set 62.Or, when Secondary resource unit set 62 is included by first resource unit set 64, UE can do CSI measurements using the non-zero power and zero energy CSI-RS on Secondary resource unit set 62, because the UE now, sent on Secondary resource unit set 62 CSI-RS will not receive common signal channel to other UE and UE and interfere.
To the schematic diagram of CSI-RS hypothesis when Fig. 6 B are the reception dedicated channels of the embodiment of the present invention.In another embodiment, as shown in Figure 6B, the Secondary resource 63 can include the first resource unit set 64, it is clear that, first resource 61 and Secondary resource 63 are overlapping completely or partially, because all including first resource unit set 64.Particularly, first resource 61 and Secondary resource 63 can be identical resources, such as, for the ePDCCH for receiving the A of form 1 in public search space, form 1A ePDCCH can not only dispatch common signal channel but also can dispatch dedicated channel.Now, the UE does not get around the first resource unit set on the Secondary resource and receives the dedicated channel, i.e., above-mentioned first resource unit set 64 is inoperative for receiving dedicated channel.Because first resource unit set 64 is exclusively used in receiving common signal channel, therefore UE receives dedicated channel and need not comprehended, The level of resources utilization of system can be improved.Alternatively, for identical Downlink Control Information, (DCI, wherein resource location, DCI format such as include DCI format 0 and/or DCI format 1A.Below by taking DCI format 1A as an example, if DCI format 1A ePDCCH passes through public CRC scramblers such as system information Radio Network Temporary Identifier (RNTI, Radio Network Temporary Identity) or the scrambling such as paging RNTI, then need hypothesis to get around public CSI-RS when doing solution rate-matched or demapping;If DCI format 1A ePDCCH is scrambled by special CRC scramblers such as cell RNTI (C-RNTI, Cell-RNTI) etc., then need hypothesis to get around special CSI-RS when doing rate-matched or demapping.
In current LTE system, UE does synchronization using CRS and RRM is measured, it is wherein synchronous to refer mainly to time-frequency essence synchronously, especially frequency precise synchronization, RRM measurements include Reference Signal Received Power (RSRP, Reference Signal Receiving Power) and Reference Signal Received Quality (RSRQ, Reference Signal Receiving Quality) measurement.Illustrated below by taking synchronization as an example.For new carrier wave NCT, CRS time domain density can reduce or even cancel CRS and send, below so that 5ms sends a CRS as an example, so for being particularly acute that the synchronous tracking accuracy of the time-frequency essence on the carrier wave of small bandwidth declines, such as 1.4HMZ and 3MHz carrier wave, because available CRS resources are reduced.Therefore, it can consider to realize synchronization using CSI-RS and CRS, or the CSI-RS that places one's entire reliance upon synchronization mechanism.And CSI-RS configuration is notified by RRC signaling in current LTE system, the UE for there was only connected state can get CSI-RS configurations, but the synchronous UE for being not in RRC connected states of time-frequency essence is also important, such as receives above-mentioned common signal channel.
Time-frequency essence can be done using part or all of CSI-RS on above-mentioned public CSI-RS first resource unit set synchronous.The sub-frame set for sending CRS or the sub-frame set for sending synchronizing signal etc. can be regard as the first sub-frame set.For example, assuming that the CRS transmission cycle is 5ms, it is subframe 0 and subframe 5 to send subframe, it can so take part or all of CSI-RS on some above-mentioned first resource unit sets synchronous to do time-frequency essence respectively in subframe 0 and subframe 5, this subframe 0 and subframe 5 may belong to the first sub-frame set, and current others subframe constitutes the first sub-frame set and is also not excluded for.It is also required to make time-frequency essence of the CSI-RS in the first sub-frame set synchronously due to being not in the UE of connected state, because in base station side, the scrambling mode of the CSI-RS can be determined by first community mark, first community mark can be the Physical Cell Identifier of current carrier, be carried by synchronizing signal.Corresponding, in UE sides, the descrambling mode of the CSI-RS can be determined by first community mark.The second sub-frame set can be constituted for the subframe in addition to the first sub-frame set, in base station side, the scrambling mode of the CSI-RS on first resource unit set in the second sub-frame set can determine that this second by second community mark Cell ID can be allocated to a certain connected state UE by RRC signaling, and second community mark is referred to as virtual subdistrict mark.Corresponding, in UE sides, the descrambling mode of the CSI-RS on first resource unit set in the second sub-frame set can be determined by second community mark.
In embodiment shown in Fig. 2 to Fig. 6 A and Fig. 6 B, a kind of method of CSI-RS transmission or reception is illustrated.For convenience of description, CSI-RS is divided into two kinds:Public CSI-RS and special CSI-RS, is respectively applied to common signal channel and dedicated channel.Optionally, the embodiments of the invention provide another method, CSI-RS transmission or reception is equally used for, in the method only a kind of CSI-RS, is equal to the special CSI-RS in former approach.In embodiment as shown in Figure 7 to 9, the method for CSI-RS transmission or reception is illustrated for the special CSI-RS in second method.

S910, base station determines the first resource of the first common signal channel, and first common signal channel includes at least one of control channel of Physical Broadcast Channel, the control channel of schedule system information block and scheduling paging information.
First common signal channel is the higher common signal channel of priority, specifically include Physical Broadcast Channel, at least one of the control channel of schedule system information block, the control channel of scheduling paging information, therefore these common signal channels are probably to be transmitted to multiple or all UE.
The first resource is the resource of the first common signal channel.Illustrated so that the first common signal channel is the control channel of schedule system information block or paging information as an example, other common signal channel similar process.Specifically, the first resource can be the candidate resource in the public search space of above-mentioned control channel, there are 4 candidate resources in such as public search space, so base station can determine the first resource that one is the first common signal channel from this 4 candidate resources, specifically can be according to the dispatch situations of multiple cells of this cell, or stagger, etc. in view of carrying out resource with the control channel of adjacent cell, it is not limited.
S915, first common signal channel is mapped on the first resource by base station by way of getting around the resource of the first reference signal, first reference signal includes cell specific reference signal CRS and/or synchronizing signal, and does not include non-zero power CSI-RS.
First common signal channel is mapped on the first resource by the base station by way of getting around the first reference signal, that is, base station is in a certain order mapped to the information of the first encoded common signal channel on first resource, in mapping process, the position of the resource unit of first reference signal can be got around, i.e., the information of the first common signal channel is not mapped toward the position of these resource units.First reference channel bag CRS and/or synchronizing signal are included, and does not include non-zero power CSI-RS, optionally, the CSI-RS of zero energy can also be included.Because these information are all known a priori by for all UE, these UE both include RRC connected state UE, also including being not in the UE of RRC connected states.After resource impact, base station can just send first common signal channel.
S920, base station is sent on the first resource before first common signal channel, in addition to:The base station is UE configurating channel state information reference signals CSI-RSs, and the CSI-RS includes non-zero power CSI-RS and/or zero energy CSI-RS, and the first resource and the CSI-RS are overlapping.
Before sending first common signal channel on the first resource in the base station, base station can also configure CSI-RS for UE, the CSI-RS can include non-zero power CSI-RS and/or zero energy CSI-RS, specifically can be by sending the proprietary signal deployments of RRC.Concrete configuration CSI-RS principle is not limited, such as according to the balance of the reference signal expense between subframe, coordination of adjacent area etc..
The CSI-RS configured is usually Whole frequency band, i.e., all include in CSI-RS, time domain including cycle and subframe position on whole PRB of current carrier on frequency domain;And when the first resource belongs to public search space, in general, public search space is that whole subframes are all present, or can also be the cycle, or can also be in some specific subframes, and first resource in time can be overlapping with the CSI-RS, on frequency domain, due to CSI-RS-as be Whole frequency band, first resource so in public search space is also certain overlapping with CSI-RS, assuming that overlapping 4 PRB, other overlapping cases are also similar process.The situation of other first resources is similar.
Because CSI-RS is the specific RRC dedicated signalings configurations of UE, therefore the only UE of RRC connected states can just get CSI-RS configurations.But, first common signal channel can be broadcast, mean that the connected state UE and UE for being not in connected state is required for receiving first common signal channel, and the UE for being not in connected state is the CSI-RS configurations for not knowing other UE on current carrier, so when first resource is overlapping with CSI-RS, the especially CSI-RS of non-zero power, if sending the first common signal channel and the non-zero power CSI-RS together on first resource, above-mentioned non-zero power CSI-RS will be received as the first common signal channel by not knowing the UE of above-mentioned CSI-RS configurations so, extra interference can be brought to the reception of the first common signal channel.It is usually broadcast in view of the first common signal channel, therefore it is important, so, first reference signal does not include non-zero power CSI-RS, when mapping the first common signal channel to first resource, above-mentioned non-zero power CSI-RS can not be got around, CSI-RS is just treated as and is not present equally, or do not send above-mentioned non-zero power CSI-RS now.The beneficial effect of above-described embodiment is, eliminates the interference that non-zero power CSI-RS is brought to the first common signal channel, it is ensured that the receptivity of the first common signal channel. For sending during the first common signal channel, the problem of whether sending CSI-RS, it is non-existent for the power disturbance of the first common signal channel in view of zero energy CSI-RS, even if UE receives zero energy CSI-RS as the first common signal channel, extra interference will not be brought, only code rate increases, therefore the receptivity of the first common signal channel will not deteriorate very serious.Therefore, the base station is sent on the first resource before first common signal channel, or first common signal channel to after the mapping step of first resource, the first common signal channel that base station can be shot away with zero energy CSI-RS mappings is punched, do not send the information of the first common signal channel in zero energy CSI-RS position, but send above-mentioned zero energy CSI-RS as usual.The beneficial effect of the embodiment of the present invention is that the first common signal channel will not be interfered, and nor affects on UE and carry out interferometry with zero energy CSI-RS, nor affects on the degree of accuracy lifting that zero energy CSI-RS is brought to channel measurement.
