Detailed description of the invention

In order to make the object, technical solutions and advantages of the present invention clearly, below in conjunction with accompanying drawing, the present invention is described in further detail, it is clear that described embodiment is only some embodiments of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, all other embodiments that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of protection of the invention.

Embodiments provide a kind of disturb information indication scheme and based on this interference information indication scheme realize AF panel scheme, in order to make the UE interference information indicated according to network side that the signal of another UE is carried out AF panel.

The embodiment of the present invention is applicable to the evolution system of LTE (longtermevolution, Long Term Evolution) system or LTE system or other systems needing to carry out AF panel.The embodiment of the present invention is applied under MU-MIMO scene, can make the UE in MU-MIMO matched group that the signal of pairing UE is carried out AF panel.

Referring to Fig. 1, for the one interference information instruction schematic flow sheet that the embodiment of the present invention provides.This flow process realizes at network side, such as, and can by base station or there is the network equipment of base station functions perform.

Step 101, it is determined that UE and the two UE.

The signal of the oneth UE may be transmitted and interfere by the signal transmission of the 2nd UE here, such as, there is intra-cell interference or presence of intercell interference between a described UE and described 2nd UE.The quantity of the 2nd UE can be one can also be multiple.Such as, UE and the two UE can be the UE in MU-MIMO pairing user's group.

In below scheme, only to indicate interference information to describe to the MU-MIMO UE matched in user's group.Here a UE can be that MU-MIMO matches any one UE, this MU-MIMO in user's group and matches in user's group the UE except a UE referred to as the 2nd UE.Under normal circumstances, for each UE in MU-MIMO pairing user's group, network side all can carry out interference information instruction according to the mode that the embodiment of the present invention provides.

The process that network side is carried out UE scheduling based on MU-MIMO technology by the embodiment of the present invention does not limit.Only enumerate a kind of scheduling process based on MU-MIMO herein.In this process, UE carries out channel estimating, obtains the channel matrix between itself and base station, then to the code book index value that SINR (SignaltoInterferenceplusNoiseRatio, the Signal to Interference plus Noise Ratio) value that base station feedback is maximum is corresponding；The code book index value of each UE feedback is collected in base station, according to each UE code book index value fed back and carry out UE pairing according to certain criterion (such as handling capacity maximal criterion) further.The quantity of the UE in MU-MIMO pairing user's group can be two, it is also possible to is two or more.

Step 102, indicates interference information to a described UE, so that the signal of described 2nd UE is carried out AF panel according to described interference information by a described UE.

In step 102, base station can be passed through dynamic signaling and indicate interference information to a UE, it is possible to indicate interference information by semi-static signaling to a UE.

Briefly, adopt semi-static signaling to carry out the instruction of interference information to refer to: the signaling of base station notice UE changes within long a period of time, such as in the time-amplitude of tens or hundreds of subframe, signaling sends once, the frequency that base station sends new interference information instruction is relatively low, meet the characteristic of semi-static notice, such as, every tens or hundreds of subframe, base station sends to UE and once disturbs information.In LTE system, a kind of possible semi-static indicating mode is RRC (RadioResourcecontrol) signaling method.

In the embodiment of the present invention, described dynamic signaling refers to the signaling that can dynamically send.Adopt dynamic signaling to carry out the instruction of interference information to refer to: base station is dynamically send for sending the signaling of interference information to UE, such as can send this signaling in each subframe, so that UE uses this interference information that the signal of pairing user is carried out AF panel according to indicated interference information in current dispatching cycle, in LTE system, this type of dynamic signaling is usually Physical Downlink Control Channel, and (English is: PhysicalDownlinkControlChannel, referred to as: PDCCH) or strengthen Physical Downlink Control Channel (English is: EnhancedPhysicalDownlinkControlChannel, referred to as: EPDCCH) send.

After UE is scheduling in base station (as MU-MIMO dispatches), the UE being scheduled in pairing user's group is made to understand the transmission parameter of pairing UE in time according to dispatch situation, to be effectively taking place AF panel, preferably, the embodiment of the present invention adopts dynamic signaling to carry out the instruction of interference information, that is, interference information is indicated by PDCCH or EPDCCH of a UE to a UE.

Wherein, PDCCH is an important physical channel in the middle of 3GPPLTE and LTE-A standard, is mainly used to carry UE resource allocation information and other control information, such as, and the resource scheduling information of up-downgoing.In general, in a subframe, it is possible to have multiple PDCCH.EPDCCH is the physical channel in the middle of 3GPPLTE-A standard, can obtain the gain of wave beam forming and diversity relative to PDCCH, EPDCCH, increases and controls the motility that the interference of channel eliminates in heterogeneous network.

Be the interference information indicated by a UE can being the transmission parameter of the 2nd UE, owing to the transmission parameter of the 2nd UE reflects the transmission characteristic of the 2nd UE, therefore the signal of the 2nd UE can be carried out effective AF panel based on the transmission characteristic of the 2nd UE by a UE.

Wherein, the 2nd UE can be in same cells with a UE, it is also possible to is in different districts with a UE.If the 2nd UE and the one UE is in same cells, then the interference signal of a UE comes from the community residing for a UE；If the 2nd UE and the one UE is in different districts, then the interference signal of a UE is from the different districts of a UE.Whether the oneth UE and the two UE is in same cells or is in different districts and does not do further restriction by the embodiment of the present invention.

In step 102, base station can indicate the transmission parameter of the 2nd UE to a UE, can also be used for demodulating the parameter of PDCCH or EPDCCH of the 2nd UE to a UE instruction, so that a UE obtains the transmission parameter of the 2nd UE by demodulating PDCCH or EPDCCH of the 2nd UE.

Correspondingly, base station can adopt the one in following two mode to indicate interference information to a UE:

First kind of way: indicate the transmission parameter of the 2nd UE to a UE.Such as, the transmission parameter of the 2nd UE is indicated either directly through PDCCH or EPDCCH of a UE.Adopt the interference information instruction flow process that this kind of mode realize can referring to subsequent embodiment one.

The second way: consider that the transmission parameter of the 2nd UE is sent to the 2nd UE usually by PDCCH or EPDCCH of the 2nd UE, therefore can be used for demodulating the parameter of PDCCH or EPDCCH of the 2nd UE to a UE instruction, so that a UE obtains the transmission parameter of the 2nd UE by demodulating PDCCH or EPDCCH of the 2nd UE.Adopt the interference information instruction flow process that this kind of mode realize can referring to subsequent embodiment two.

Considering when minizone MU-MIMO transmission, receiver is likely to require knows demodulation order, in order to effectively carry out AF panel.

Assume that UE uses the interference of code word level to eliminate (codeword-levelinterferencecancellation, referred to as: CWIC) receiver, and to distribute to total transmitting power of user's matched group be P in base station, by L (0≤L≤1) ratio power distribute to a UE, the power of (1-L) ratio is distributed to the 2nd UE, then the signal that a UE receives is:

$y_1=\sqrt{\mathrm{PL}}{h}_1{x}_1+\sqrt{P(1-L)}{h}_1{x}_2+n_1\·\·\·\left(1\right)$

Wherein, x₁Represent UE data, x₂Represent the 2nd UE data, h₁Represent channel, n₁Represent the noise and interference that receive.

The signal that 2nd UE receives is:

$y_2=\sqrt{\mathrm{PL}}{h}_2{x}_2+\sqrt{P(1-L)}{h}_2{x}_2+n_2\·\·\·\left(2\right)$

Wherein, x₁Represent UE data, x₂Represent the 2nd UE data, h₂Represent channel, n₂Represent the noise and interference that receive.

If a UE does not eliminate the 2nd UE to the interference that brings of a UE, then a UE signal to noise ratio (English is: SignaltoNoiseRatio, referred to as: SNR) be:

$\mathrm{SNR}=\frac{\mathrm{PL}}{P(1-L)+R_n}\·\·\·\left(3\right)$

If a UE first demodulates the interference signal of the 2nd UE, it is suppressed that or after the signal of elimination the 2nd UE, the transmission signal of re-demodulation the oneth UE, then the SNR of a UE is:

$\mathrm{SNR}=\frac{\mathrm{PL}}{R_n}\·\·\·\left(4\right)$

Wherein, R_nIt it is the jamming power of a UE other community received.

It can be seen that a UE demodulation order influence whether the oneth UE demodulation after SNR.Network side can dispatch suitable MCS according to the UE SNR value being likely to observe when scheduling.If the demodulation order of a UE is inconsistent with network side desired demodulation order, then the SNR that the MCS of network side scheduling can be an actually-received with a UE does not mate.

In order to solve above-mentioned unmatched problem, in the embodiment of the present invention, preferably, network side also to indicate demodulation order to a described UE, to indicate a described UE directly to demodulate the data of a described UE, or the data of a UE described in re-demodulation after first the signal of described 2nd UE being carried out AF panel or eliminating.Concrete, can be indicated by dynamic signaling, indicate than PDCCH or EPDCCH such as by a UE.

As previously mentioned, when base station carries out UE scheduling based on MU-MIMO technology, the user's matched group determined generally comprises two UE, in this case, in the step 102 of above-mentioned flow process, base station is by the transmission parameter of the 2nd UE of a UE centering or is used for demodulating the information of PDCCH or EPDCCH of other all UE described and is indicated to a UE, so that the signal of the 2nd UE is carried out AF panel according to this parameter by a UE.When base station carries out UE scheduling based on MU-MIMO technology, also plural UE can be dispatched in user's matched group, in this case, in the step 102 of above-mentioned flow process, base station is by the transmission parameter of other all UE except a UE in user's matched group or is used for demodulating the information of PDCCH or EPDCCH of other all UE described and is indicated to a UE, so that the signal of these UE is carried out AF panel according to the transmission parameter of these UE by a UE.

LTERel.12 introduces NAICS (Network-assistedinterferencecancellation/suppression, the interference of auxiliary Network Based eliminates and suppresses) receiver, thus can carry out suppressing or eliminating more effective for presence of intercell interference in UE side.But owing to the MU-MIMO of existing system is the scheduling of base station, UE does not know whether that oneself and another one UE are scheduled in MU-MIMO transmission, which type of transmission characteristic what also do not know the UE employing matched is, therefore UE cannot use NAICS receiver to carry out AF panel by the characteristics of signals of understanding pairing UE.

After adopting the embodiment of the present invention, network side indicates interference information for the MU-MIMO UE matched in user, enables a described UE, according to described interference information, the signal of described 2nd UE is carried out AF panel.In this process, realize owing to MU-MIMO technology is based on network side scheduling, network side can obtain the interference information that MU-MIMO scheduling is relevant, and can further this interference information be sent to MU-MIMO pairing user, so that the UE that MU-MIMO matches in user carries out AF panel according to this interference information.

Certainly, the embodiment of the present invention is not limited only under MU-MIMO scene to apply, and under other scenes, if the signal transmission of certain UE may be subject to the interference of the signal transmission of other UE, then the embodiment of the present invention can also be adopted to carry out AF panel.

One the interference information instruction flow process adopting the first kind of way in above-mentioned steps 102 to realize is described by the examples below.

As in figure 2 it is shown, this flow process comprises the steps that

Step 201, it is determined that UE and the two UE；

The signal of the oneth UE may be transmitted and interfere by the signal transmission of the 2nd UE here, such as, there is intra-cell interference or presence of intercell interference between a described UE and described 2nd UE.

Step 202, indicates the transmission parameter of described 2nd UE to a described UE.Concrete, PDCCH or EPDCCH that can pass through a UE indicates the transmission parameter of described 2nd UE to a described UE.

In step 202, it is possible to described interference information is sent to a described UE.In order to reduce the data volume being sent to a UE, it is preferable that the embodiment of the present invention can use subset restriction, and (English is: mode subsetrestriction) is to indicate interference information.

In simple terms, described subset restriction mode refers to: the interference information one group possible of the 2nd UE be stored in advance in a transmission subset of parameters, it is possible to by high-level signaling, the content of this subset is sent to a described UE.So, when indicating the transmission parameter of the 2nd UE to a described UE, described transmission parameter index information in transmission subset of parameters can be sent to a described UE, so that a described UE obtains the transmission parameter of correspondence according to described index information in transmission subset of parameters.Preferably, a transmission subset of parameters comprises one group of the 2nd UE transmission parameter being likely to use, and the kind of all transmission parameters comprised in a transmission subset of parameters is identical.

Further, consider that some transmission parameter of the 2nd UE is likely to identical with the transmission parameter of a UE, in order to reduce the quantity of information of transmission, in the embodiment of the present invention preferably, instruction information can be sent to a UE, this instruction information is for indicating certain type of the 2nd UE or certain form of transmission parameter identical with the value of the homogeneous transport parameter of a UE, so that the signal of the 2nd UE is carried out AF panel according to the transmission parameter of oneself by a UE.

For example, base station can send the first instruction information to a described UE, and described first instruction information is used for indicating one of herein below or combination in any:

Antenna port CRS quantity and the mapping scheme of described 2nd community, UE place are identical with a described community, UE place；

The MSBFN sub-frame configuration of described 2nd community, UE place is identical with a described community, UE place；

The PDSCH primary sign position of described 2nd community, UE place is identical with a described community, UE place；

The mapping scheme of the signal of described 2nd UE is identical with the mapping scheme of the signal of a described UE.

Further, consider that UE carries out disturbing the parameter eliminated the need for depend on receiver type, the interference information that different types of receiver adopts is likely to different, it is therefore preferred to, following steps can be performed: the type according to the receiver of a described UE, it is determined that need the kind of transmission parameter of described 2nd UE to a described UE instruction before step 202.

The kind of receiver has multiple, the embodiment of the present invention eliminates (codeword-levelinterferencecancellation with the interference based on code word level, referred to as: CWIC) receiver is as example, the content of indicated interference information is illustrated, other kinds of receiver situation is similar, is not added with at this repeating.The transmission parameter of the 2nd UE that the CWIC receiver of the oneth UE may need can include following several in one or combination in any:

1) the antenna port quantity of CRS (Cell-specificreferencesignals, community own reference signal) and mapping scheme are (English: mappingscheme)；

2) MBSFN (MultimediaBroadcastmulticastserviceSingleFrequencyNetwor k, multicast/multicast single-frequency network network) subframe configuration information；

3) Physical Downlink Shared Channel (PhysicalDownlinkSharedChannel, PDSCH) primary sign positional information；

4) CSI-RS (ChannelStateIndication referencesignals) resource information, described CSI-RS includes zero energy CSI-RS power and non-zero power CSI-RS；

5) signal power information, described signal power information includes PA, or includes, or other power exterior syndrome parameter；

6) modulation and encoding scheme (English is: modulation/codingscheme, referred to as: MCS)；

7) UE mark；

8) order instruction (English is: rankindication, referred to as: RI), pre-coding matrix instruction (English is: precodingmatrixindicator, referred to as: PMI)；

9) whether there is the instruction information of interference；

10) scrambling code information, it is possible to be the instruction information of the scrambler used, such as, it is possible to be scrambling code identification (ScramblingID), or virtual subdistrict mark (English: virtualcellID, referred to as: VCID).

Introduce above-mentioned transmission parameter in detail below.

(1) the antenna port quantity of CRS and mapping scheme

The antenna port quantity of CRS refers to the quantity of the antenna port sending CRS.CRS effect in downstream includes being some information during Bearer Channel precoding, helps UE to do the channel estimating of down channel, it is also possible to for channel instruction transmission and Channel Detection.CRS row antenna port in each of the lower transmits a reference signal.Antenna port is defined by the CRS sent for this antenna.

Mapping scheme refers to the mapping pattern of CRS to time/frequency.In LTE system, the CRS of different districts has different displacements (frequencyshift) for its community Cell_ID on frequency domain, corresponding to different frequencyshift, CRS is mapped on different resourceelement, so reducing interference between the CRS of different districts, the value of frequencyshift corresponds to mod (CellID/6).Mapping scheme reflects the resource of CRS and maps situation.The PDSCH signal sent in another one community is depending on mapping round CRS signal, and the resourceelement of carrying CRS is not used in other signals of transmission, so the information of CRS also delivers the PDSCH mapping at time domain/frequency domain accordingly.

Oneth UE is according to the antenna port quantity of CRS and mapping scheme, it is possible to the PDSCH obtaining the 2nd UE maps on which time/frequencyresourceelement, suppresses with its interference signal corresponding.

Mapping scheme can use the frequency offset of CRS to represent, wherein, the frequency offset of described CRS can be described 2nd UE community CRS frequency offset amount；It can also be the CRS frequency offset difference with the CRS frequency offset of a described community, UE place of described 2nd community, UE place.Such as, the mapping scheme of the 2nd UE is represented by C_shift_2-C_shift_1, and wherein, C_shift_2 represents the CRS frequency offset amount of the community at the 2nd UE place, and C_shift_1 represents the CRS frequency offset amount of the community at a UE place.

In Rel.12, the antenna port quantity of CRS and mapping scheme are semi-statically configured by high-level signaling.Can along in this way to the antenna port quantity of the CRS of UE instruction the 2nd UE and mapping scheme in the embodiment of the present invention, may be used without the dynamic signaling antenna port quantity to the CRS of UE instruction the 2nd UE and mapping scheme, described dynamic signaling is sent by PCDDH or EPDCCH of a UE.

In order to reduce the data volume of transmission, to reduce network resource overhead, in one implementation, network side can pass through high-level signaling and configure the antenna port quantity of a CRS and the subset of mapping scheme to a UE, comprises the antenna port quantity of CRS one group possible and the parameter of mapping scheme in this subset；Network side can use which parameter in this subset that the signal of the 2nd UE is carried out AF panel by dynamic signaling to a UE instruction, such as, by indicating the index information of parameter, a UE is made to obtain antenna port quantity and the mapping scheme of CRS corresponding in this subset according to this index information.

When intra-cell interference comes from MU-MIMO transmission, oneth UE and the two UE is in same community, owing to interference comes from same community, network side can not to the antenna port quantity of the CRS of UE instruction the 2nd UE and mapping scheme, and a UE is it is believed that the 2nd UE has antenna port quantity and the mapping scheme of the CRS identical for UE oneself with the oneth.

Due to the antenna port quantity of the antenna port quantity of CRS of the 2nd UE and the CRS of mapping scheme and a UE and mapping scheme be likely to identical be likely to different, therefore network side can pass through dynamic signaling whether send instruction information to a UE identical with antenna port quantity and the mapping scheme of the CRS of the antenna port quantity and mapping scheme and a UE that indicate the CRS of the 2nd UE, and this instruction information can be the instruction information of 1 bit.If it is identical that this instruction information indicates both, then a UE is when carrying out AF panel, it is believed that the PDSCH's of the 2nd UE maps the CRS antenna port quantity corresponding to community, place and mapping scheme, AF panel is carried out with the signal to the 2nd UE, if this instruction information indicates both differences, then can in the manner previously described to the antenna port quantity of the CRS of UE instruction the 2nd UE and mapping scheme.

(2) MSBFN subframe configuration information

MSBFN subframe configuration information can be semi-statically configured by high-level signaling, it is possible to adopting the mode of dynamic signaling to indicate the MSBFN subframe configuration information of the 2nd UE to a UE, described dynamic signaling is sent by PDCCH or EPDCCH of a UE.

In order to reduce the data volume of transmission, to reduce network resource overhead, in one implementation, network side can pass through high-level signaling to the UE subset configuring a MSBFN subframe configuration information, comprises MSBFN sub-frame configuration parameter one group possible in this subset；Network side can use which parameter in this subset that the signal of the 2nd UE is carried out AF panel by dynamic signaling to a UE instruction, such as, by indicating the index information of parameter, a UE is made to obtain MSBFN subframe configuration information corresponding in this subset according to this index information.

When intra-cell interference comes from MU-MIMO transmission, oneth UE and the two UE is in same community, owing to interference comes from same community, network side can not indicate the MSBFN subframe configuration information of the 2nd UE to a UE, and a UE is it is believed that the 2nd UE has the MSBFN subframe configuration information identical for UE oneself with the oneth.

Due to the MSBFN subframe configuration information of the MSBFN subframe configuration information of the 2nd UE and a UE be likely to identical be likely to different, therefore whether network side can be identical to the UE MSBFN subframe configuration information sending instruction information MSBFN subframe configuration information and a UE to indicate the 2nd UE by dynamic signaling, and this instruction information can be the instruction information of 1 bit.If it is identical that this instruction information indicates both, then a UE is when carrying out AF panel, the signal of the 2nd UE is carried out AF panel by the MSBFN subframe configuration information that can use community, place, if this instruction information indicates both differences, then can indicate the MSBFN subframe configuration information of the 2nd UE in the manner previously described to a UE.

(3) PDSCH primary sign positional information

The PDSCH primary sign position of the 2nd UE can use the absolute location information of the PDSCH primary sign of the 2nd UE, such as, the numbering of this primary sign, it is also possible to be the PDSCH primary sign relative position with the PDSCH primary sign of a UE of the 2nd UE, the such as difference of both symbol number.

In order to reduce the data volume of transmission, to reduce network resource overhead, in one implementation, network side can pass through high-level signaling to the UE subset configuring a PDSCH primary sign positional information, comprises PDSCH primary sign position one group possible in this subset；Network side can use which parameter in this subset that the signal of the 2nd UE is carried out AF panel by dynamic signaling to a UE instruction, such as, by indicating the index information of parameter, a UE is made to obtain PDSCH primary sign positional information corresponding in this subset according to this index information.

When intra-cell interference comes from MU-MIMO transmission, oneth UE and the two UE is in same community, interference comes from same community, if the transmission mode that UE and the two UE adopts is the one in TM1 to TM9, and not across carrier dispatching, then UE and the two UE has identical PDSCH primary sign position, therefore network side can not indicate PDSCH primary sign positional information to a UE, and a UE is it is believed that the 2nd UE has the PDSCH primary sign position identical for UE oneself with the oneth.If having the UE transmission mode adopted in UE and the two UE is TM10, or employs across carrier dispatching, then indicate the PDSCH primary sign position of the 2nd UE in the manner previously described to a UE.

It is likely to different owing to the PDSCH primary sign position of the 2nd UE is possible identical from the PDSCH primary sign position of a UE, therefore whether network side can be identical to the UE PDSCH primary sign position sending instruction information PDSCH primary sign position Yu a UE to indicate the 2nd UE by dynamic signaling, and this instruction information can be the instruction information of 1 bit.If it is identical that this instruction information indicates both, then a UE is when carrying out AF panel, according to the PDSCH primary sign position of a UE, the signal of the 2nd UE can be carried out AF panel, if this instruction information indicates both differences, then can indicate the PDSCH primary sign position of the 2nd UE in the manner previously described to a UE.

(4) signal power information, described signal power information includes PA, or includes

PA characterizes not to be had the OFDM of pilot tone (English is: OrthogonalFrequencyDivisionMultiplexing, referred to as: the OFDM) ratio of the data tone power of symbol and pilot sub-carrier power, herein, the OFDM symbol not having pilot tone is called A class symbol；PB characterizes the data tone power of the OFDM symbol having pilot tone and the ratio of pilot sub-carrier power, herein, the OFDM symbol having pilot tone is called B class symbol.By PA and PB information, UE may determine that the transmit power of self PDSCH, carries out PDSCH demodulation accordingly.It should be noted that the power information notifying UE in LTE system be PA and

Under the transmission mode based on CRS, network side can pass through dynamic signaling by the information of the 2nd UE absolute signal powers, or the information of the proportionate relationship of the 2nd UE power and a UE power informs a UE.

Such as, by PA and/or PB of the 2nd UE, or the power information of its correspondence, it is indicated to a UE.Concrete, network side can pass through PDCCH or EPDCCH of a UE, by the PA of the 2nd UE, PB,In one or more inform a UE.

Again such as, network side can pass through PDCCH or EPDCCH of a UE, and one of following information or combination are informed to a UE:

The ratio of the PA of PA and the one UE of the 2nd UE；

The ratio of the PB of PB and the one UE of the 2nd UE；

2nd UE'sWith a UE'sRatio.

Such as, the content informing a UE comprises the steps that

△=P_{A, 2}/P_{A, 1}And/or △=P_{B, 2}/P_{B, 1}

Wherein, P_A1Represent PA, the P of a UE_A2Represent PA, the P of the 2nd UE_B1Represent PB, the P of a UE_B2Represent the PB of the 2nd UE.

Under the transmission mode based on DMRS (Demodulationreferencesignals, reconcile reference signal), legacy system need not by PA orValue notice UE because UE need not this information carry out data demodulation.But when dynamic disturbance eliminates, a UE, it is to be appreciated that the corresponding relation of power of the 2nd UE and the one UE, carries out suitable disturbance reconstruction and elimination.For the purpose of it, a UE's dynamically controls signaling (such as PDCCH/EPDCCH) and dynamically the relation information of the power of the 2nd UE and the one UE can be informed to a UE；This type of power relation includes but not limited to, the PA ratio of the 2nd UE and the one UE, the PB ratio of the 2nd UE and the one UE, the 2nd UE'sOneth UE'sRelativeness etc..

Wherein, the PB of the 2nd UE can be informed to a UE and also can not notify this PB to a UE by network side.If do not notify the PB of the 2nd UE to a UE, then a UE is it is believed that the PB of PB and the one UE of the 2nd UE is identical；If notify the PB of the 2nd UE to a UE, the PB notified can represent the PB of the interference of community, a UE place generation or the PB of adjacent cell.

In order to reduce the data volume of transmission, to reduce network resource overhead, in one implementation, network side can configure one by high-level signaling to a UESubset, this subset comprises one group possibleOr one groupDifference, such as, the 2nd UE'sWith a UE'sDifference；Network side uses which parameter in this subset that the signal of the 2nd UE is carried out AF panel by dynamic signaling to a UE instruction, such as, by indicating the index information of parameter, makes a UE obtain correspondence in this subset according to this index informationOrDifference.

In another embodiment, network side by distributing to the PA of the 2nd UE or can distribute to the PA of the 2nd UE ratio accounting for the general power of all UE distributed in user's matched group, is indicated to a UE.In MU-MIMO transmission, network side is distributed to the general power of user's matched group and can be distributed in each UE in this user's matched group.Network side can pass through dynamic signaling notify that a certain UE distributes to the power of this UE.Here, when the lateral UE notice of network distributes to the power of this UE, the absolute power distributing to this UE can being informed to this UE, it is also possible to a ratio is informed to this UE, this ratio represents that network side distributes to the power of this UE and the ratio of the general power distributing to this UE place user's matched group.Such as, the lateral UE of network notifies a ratio value L, the ratio of general power then representing the power that network side distributes to a UE and the user's matched group distributing to this UE place is L, or represent network side distribute to a UE power and distribute to this UE place user other users of matched group the ratio of power be L.Can dynamically changing owing to matching the number of user in MU-MIMO, so the power that network side distributes to a certain user can also dynamically change, PA can be notified by dynamic signaling by network side.

(5) MCS

If a UE uses CWIC receiver, then a UE needs the MCS according to the 2nd UE to carry out codeword decoding and reconstruct.

The MCS of the 2nd UE can be informed to a UE by dynamic signaling by PDCCH or EPDCCH of a UE by network side.

The MCS of the 2nd UE can be sent to a UE by network side, it is also possible to the difference between the MCS of MCS and the one UE of the 2nd UE is sent to a UE, so that a UE determines the MCS of the 2nd UE.

In order to reduce the data volume of transmission, to reduce network resource overhead, in one implementation, network side can pass through high-level signaling to the UE subset configuring a MCS, comprises MCS one group possible in this subset；Network side can use which parameter in this subset that the signal of the 2nd UE is carried out AF panel by dynamic signaling to a UE instruction, such as, by indicating the index information of parameter, makes a UE obtain MCS corresponding in this subset according to this index information.Or UE1 can pass through the blind check MCS that blind check the 2nd UE uses in the MCS subset that high-level signaling configures.

Further, network side can to the oneth UE indicate a MCS, in this case, a UE think all Physical Resource Block of UE (English is: PhysicalResourceBlock, referred to as: PRB) upper interference is broadly fallen into this MCS.Network side can also indicate corresponding a set of PRB couple of multiple MCS, each MCS, a UE can determine the TBS (TransportBlockSet, transport block set) of the 2nd UE according to the corresponding relation of MCS and PRB pair to a UE.

Further, at the redundancy versions of the receiver of receiver needs the 2nd UE of a UE, (English is: redundantversion), and network side can also pass through the redundancy versions that dynamic signaling indicates the receiver of the 2nd UE to a UE.

(6) UE mark

The scrambler sequence that the PDSCH of the 2nd UE uses is the function of the mark of the 2nd UE, and a UE is in order to demodulate the PDSCH of the 2nd UE, it is necessary to know the mark of the 2nd UE.

The mark of the 2nd UE can be informed to a UE by dynamic signaling by the PDCCH of a UE by network side.

The mark of the 2nd UE can be sent to a UE by network side, it is also possible to the difference between mark and the mark of a UE of the 2nd UE is sent to a UE, so that a UE determines the mark of the 2nd UE.

In order to reduce the data volume of transmission, to reduce network resource overhead, in one implementation, network side can pass through high-level signaling and configure the subset of a UE mark to a UE, this subset comprises one group of UE mark being possibly used for PDSCH is carried out scrambling, network side uses which parameter in this subset that the signal of the 2nd UE is carried out AF panel by dynamic signaling to a UE instruction, such as, by indicating the index information of parameter, a UE is made to obtain UE mark corresponding in this subset according to this index information.

Further, the scrambling code information of the PDSCH of the 2nd UE can be directly notified the function that the PDSCHscramblingsequence of UE. the 2nd UE can be following parameter by the signaling of the oneth UE: the UE-ID of the 2nd UE, the nSCID of the 2nd UE, or the virtualcellID of the 2nd UE.The information (can comprise above-mentioned parameter) of the scramblingsequence function of the PDSCH of the 2nd UE can be informed to UE by the signaling (including dynamic PDCCH/EPDCCH signaling) of the oneth UE.

Two the interference information instruction flow process adopting the second way in above-mentioned steps 102 to realize is described by the examples below.

As it is shown on figure 3, this flow process comprises the steps that

Step 301, it is determined that UE and the two UE.The execution of this step can step 201 in flow process shown in Figure 2.

Step 302, to a described UE instruction for demodulating the parameter of PDCCH or EPDCCH of described 2nd UE, so that a described UE obtains the transmission parameter of described 2nd UE by demodulating PDCCH or EPDCCH of described 2nd UE.Concrete, PDCCH or EPDCCH of a described UE can be passed through, indicate the transmission parameter of described 2nd UE to a described UE.

In step 302, network side can adopt dynamic signaling or semi-static signaling to carry out the instruction of above-mentioned information to a UE.In a kind of possible implementation, the parameter being used for demodulating PDCCH or EPDCCH of the 2nd UE semi-static mode can be informed to a UE by base station, then PDCCH or EPDCCH of UE dynamic demodulation the 2nd UE, to obtain the transmission parameter of the 2nd UE, thus carrying out AF panel.

No matter PDCCH or EPDCCH of the 2nd UE be public search space (English: send in commonsearchspace) or UE dedicated search space (English: UE-specificsearchspace) to send, it is to be appreciated that the transmission mode of the 2nd UE is (English: transmissionmode) to identify with UE during PDCCH or EPDCCH of demodulation the 2nd UE.Therefore, in the step 302 of above-mentioned flow process, the parameter of PDCCH or EPDCCH for demodulating the 2nd UE includes the one in following parameter or combination in any:

The transmission mode of described 2nd UE；

The mark of described 2nd UE；

The scrambling code information of PDCCH or EPDCCH of described 2nd UE.

In step 302, the parameter of the above-mentioned PDCCH for demodulating the 2nd UE can be sent to a UE by network side.

In order to reduce the data volume of transmission, to reduce network resource overhead, in one implementation, network side can pass through high-level signaling and configure a subset of parameters to a UE, comprises the parameter of the PDCCH for demodulating the 2nd UE one group possible in this subset；Network side uses which or which parameter in this subset to demodulate the PDCCH of the 2nd UE by dynamic signaling to a UE instruction, such as, by indicating the index information of parameter, makes a UE obtain parameter corresponding in this subset according to this index information.

If being realized by EPDCCH during the scheduling of the 2nd UE, then a UE needs the EPDCCH of demodulation the 2nd UE to obtain the transmission parameter of the 2nd UE to carry out AF panel.In this case, in step 302, the parameter of the described EPDCCH for demodulating the 2nd UE also to include the one in following parameter or combination in any:

1) quantity of EPDCCH subset；

2) index of the PRB in each EPDCCH subset；

In order to reduce the data volume of transmission, to reduce network resource overhead, in one implementation, network side can pass through high-level signaling and configure a subset of parameters to a UE, comprises the parameter of the EPDCCH for demodulating the 2nd UE one group possible in this subset；Network side uses which or which parameter in this subset to demodulate the EPDCCH of the 2nd UE by dynamic signaling to a UE instruction, such as, by indicating the index information of parameter, makes a UE obtain parameter corresponding in this subset according to this index information.

Referring to Fig. 4, for the AF panel schematic flow sheet that the embodiment of the present invention provides.This flow process realizes in user equipment side, is described using a UE as executive agent in below scheme.This flow process comprises the steps that

Step 401, a UE obtains indicated interference information.

In this step, a UE obtains indicated interference information from network side, the lateral UE of network indicate interference information process can step 101 in flow process shown in Figure 1, do not repeat them here.

Step 402, the signal of the 2nd UE is carried out AF panel according to indicated interference information by a UE.

Here, the signal transmission of a UE may be subject to the interference of the signal transmission of the 2nd UE, such as, there is intra-cell interference or presence of intercell interference between a described UE and described 2nd UE.Wherein, the quantity of the 2nd UE can be one, it is also possible to is multiple.Such as, UE and the two UE can be the UE in MU-MIMO pairing user's group.

In below scheme, only obtain the transmission parameter of the 2nd UE in pairing user's group for the MU-MIMO UE matched in user's group to describe, here a UE can be that MU-MIMO matches any one UE, this MU-MIMO in user's group and matches in user's group the UE except a UE referred to as the 2nd UE.

In step 402, a described UE can pass through the interference information that dynamic signaling acquisition is indicated, it is also possible to obtains indicated interference information by semi-static signaling.

After UE is scheduling in base station (as MU-MIMO dispatches), the UE being scheduled in pairing user's group is made to understand the transmission parameter of pairing UE in time according to dispatch situation, to be effectively taking place AF panel, preferably, the embodiment of the present invention adopts dynamic signaling to carry out the instruction of interference information, correspondingly, a UE obtains the interference information of the lateral UE instruction of network by PDCCH or EPDCCH.

Be the interference information indicated by a UE can being the transmission parameter of the 2nd UE, owing to the transmission parameter of the 2nd UE reflects the transmission characteristic of the 2nd UE, therefore the signal of the 2nd UE can be carried out effective AF panel based on the transmission characteristic of the 2nd UE by a UE.

Wherein, the 2nd UE can be in same cells with a UE, it is also possible to is in different districts with a UE.If the 2nd UE and the one UE is in same cells, then the interference signal of a UE comes from the community residing for a UE；If the 2nd UE and the one UE is in different districts, then the interference signal of a UE is from the different districts of a UE.Whether the oneth UE and the two UE is in same cells or is in different districts and does not do further restriction by the embodiment of the present invention.

In step 402, oneth UE can obtain the transmission parameter of the 2nd UE indicated by network side, can also be sent to the parameter of PDCCH or EPDCCH for demodulating the 2nd UE of a UE according to network side, PDCCH or EPDCCH of demodulation the 2nd UE is to obtain the transmission parameter of the 2nd UE.

In embodiments of the present invention, a UE can obtain the transmission parameter of the 2nd UE by following two mode:

First kind of way: the transmission parameter of the acquisition the 2nd UE indicated by network side.Such as, receiving, by PDCCH or EPDCCH of a UE, the transmission parameter about the 2nd UE that network side sends, the flow process adopting the transmission parameter obtaining the 2nd UE in this way may refer to subsequent embodiment three.

The second way: owing to the transmission parameter of the 2nd UE is sent to the 2nd UE typically by PDCCH or EPDCCH of the 2nd UE, so a UE can be sent to the parameter of PDCCH or EPDCCH for demodulating the 2nd UE of a UE according to network side, obtain the transmission parameter of the 2nd UE by demodulating PDCCH or EPDCCH of the 2nd UE.The flow process adopting the transmission parameter obtaining the 2nd UE in this way may refer to subsequent embodiment four.

Further, it is contemplated that when minizone MU-MIMO transmission, receiver is likely to require and knows demodulation order, in order to effectively carry out AF panel.It is therefore preferred that network side also to indicate demodulation order to a described UE, to indicate a described UE directly to demodulate the data of a described UE, or the data of a UE described in re-demodulation after first the signal of described 2nd UE being carried out AF panel or eliminating.Concrete, can be indicated by dynamic signaling, indicate than PDCCH or EPDCCH such as by a UE.Correspondingly, a UE demodulation order indicated by network side can carry out signal demodulation.

After adopting the embodiment of the present invention, network side indicates interference information for the MU-MIMO UE matched in user, enables a described UE, according to described interference information, the signal of described 2nd UE is carried out AF panel.In this process, realize owing to MU-MIMO technology is based on network side scheduling, network side can obtain the interference information that MU-MIMO scheduling is relevant, and can further this interference information be sent to MU-MIMO pairing user, so that the UE that MU-MIMO matches in user carries out AF panel according to this interference information.

Certainly, the embodiment of the present invention is not limited only under MU-MIMO scene to apply, and under other scenes, if the signal transmission of certain UE may be subject to the interference of the signal transmission of other UE, then the embodiment of the present invention can also be adopted to carry out AF panel.

Three first kind of way described in above-mentioned steps 401 obtain the flow process of the interference information indicated by network side by the examples below.As it is shown in figure 5, this flow process may include that

Step 501, a UE obtains the transmission parameter of the 2nd indicated UE.

Step 502, a described UE carries out AF panel according to the signal of transmission parameter the 2nd UE of the 2nd indicated UE.

For reducing the quantity of information of transmission, in step 502, it is preferable that the embodiment of the present invention can use the mode of subset restriction to indicate the transmission parameter of the 2nd UE.In simple terms, subset restriction mode refers to, the transmission parameter storage one group possible of described 2nd UE is in that in a transmission subset of parameters and is sent to a UE by high-level signaling.Oneth UE can transmit parameter index information in transmission subset of parameters according to what network side sent about the 2nd UE, obtains the transmission parameter of the 2nd UE from this transmission subset of parameters.Preferably, a transmission subset of parameters comprises one group of the 2nd UE transmission parameter being likely to use, and the kind of all transmission parameters comprised in a transmission subset of parameters is identical.

Further, owing to some transmission parameter of the 2nd UE is likely to identical with the transmission parameter of a UE, in order to reduce the quantity of information of transmission, in the embodiment of the present invention preferably, oneth UE can according to the instruction information of network side, determine that certain type in the 2nd UE or certain form of transmission parameter are identical with the transmission parameter value of oneself, draw up thus the signal of the 2nd UE is carried out interference.This instruction information can be sent to a UE by dynamic signaling, such as, is sent to a UE by PDCCH or EPDCCH of a UE.

For example, a UE can determine the transmission parameter of the 2nd UE according to the first instruction information that network side sends, and wherein, described first instruction information is used for indicating one of herein below or combination in any:

Antenna port CRS quantity and the mapping scheme of described 2nd community, UE place are identical with a described community, UE place；

The MSBFN sub-frame configuration of described 2nd community, UE place is identical with a described community, UE place；

The PDSCH primary sign position of described 2nd community, UE place is identical with a described community, UE place；

The mapping scheme of the signal of described 2nd UE is identical with the mapping scheme of the signal of a described UE.

The concrete kind of the transmission parameter of above-mentioned 2nd UE depends on receiver type, and the interference information that different types of receiver adopts is likely to different.In embodiments of the present invention, using the CWIC receiver of a UE as example, the transmission parameter type of the 2nd UE needed to a UE instruction is illustrated, owing to receiver type is relatively more, the disposition of other type of receiver and the disposition type of CWIC receiver, be not added with at this repeating.In embodiments of the present invention, the interference information that the CWIC receiver of a UE may need can include following several in one or combination in any:

1) the antenna port quantity of CRS and mapping scheme；

2) MBSFN sub-frame configuration information；

3) Physical Downlink Shared Channel primary sign positional information；

4) CSI-RS information, described CSI-RS includes zero energy CSI-RS power and non-zero power CSI-RS；

9) whether there is the instruction information of interference；

10) scrambling code information, it is possible to be the instruction information of the scrambler used, such as, it is possible to be scrambling code identification, or virtual subdistrict mark.

Previous embodiment is asked for an interview in the explanation of any of the above transmission parameter, does not repeat them here.

Preferably, in order to reduce network resource overhead, in a kind of possible implementation, network side configures the subset of the antenna port order of magnitude mapping scheme of the CRS of the 2nd UE by high-level signaling to a UE, comprises the antenna port quantity of CRS one group possible and the parameter of mapping scheme in this subset.The antenna port order of magnitude mapping scheme of the CRS of the 2nd UE index information in this subset is sent to a UE by dynamic signaling by network side, oneth UE obtains the antenna port order of magnitude mapping scheme of the CRS of correspondence according to this index information from this subset, and the signal of the 2nd UE is carried out AF panel by the transmission parameter according to the 2nd UE got.

Preferably, when intra-cell interference comes from MU-MIMO transmission, oneth UE and the two UE is in same community, and owing to interference comes from same community, a UE can confirm that the 2nd UE has antenna port quantity and the mapping scheme of the CRS identical with oneself.Due to the antenna port quantity of the antenna port quantity of CRS of the 2nd UE and the CRS of mapping scheme and a UE and mapping scheme be likely to identical be likely to different, therefore to the UE dynamic signaling sent, a UE can determine that whether the antenna port quantity of the antenna port quantity of CRS of the 2nd UE and the CRS of mapping scheme and a UE and mapping scheme be identical according to network side, wherein, the dynamic signaling that the network side that a UE receives sends can be the instruction information of 1 bit.If according to the instruction information that network side sends, a UE determines that both are identical, then the signal of the 2nd UE according to the antenna port quantity of the CRS of the 2nd UE and mapping scheme, can be carried out AF panel by a UE；If according to the instruction information that network side sends, a UE determines that both differ, then antenna port quantity and the mapping scheme of the CRS of the 2nd UE determined by UE needs according to the dynamic signaling that network side sends, thus the signal of the 2nd UE is carried out AF panel.

Preferably, in order to reduce network resource overhead, in a kind of possible implementation, network side is the UE subset configuring a MSBFN subframe configuration information by high-level signaling, comprises MSBFN sub-frame configuration parameter one group possible in this subset.Network side sends the MSBFN sub-frame configuration parameter of the 2nd UE index information in this subset by dynamic signaling or semi-static signaling to a UE, oneth UE can obtain the MSBFN sub-frame configuration parameter of correspondence according to this index information from this subset, and with this, signal of the 2nd UE is carried out AF panel.

Preferably, when intra-cell interference comes from MU-MIMO transmission, UE and the two UE is in same community, and owing to interference comes from same community, a UE can confirm that the 2nd UE has the MSBFN subframe configuration information identical with oneself.

Due to the MSBFN subframe configuration information of the MSBFN subframe configuration information of the 2nd UE and a UE be likely to identical be likely to different, therefore according to the lateral UE of the network dynamic signaling sent, a UE can determine that whether the MSBFN subframe configuration information of the MSBFN subframe configuration information of the 2nd UE and a UE is identical, wherein, the dynamic signaling that the network side that a UE receives sends can be the instruction information of 1 bit.If according to the instruction information that network side sends, a UE determines that both information is identical, then a UE is when carrying out disturbing and drawing up, and according to the MSBFN subframe configuration information of a UE, the signal of the 2nd UE can be carried out AF panel；If according to the instruction information that network side sends, a UE determines that both differ information, then a UE needs the dynamic signaling sent according to network side to determine the MSBFN subframe configuration information of the 2nd UE.

Preferably, in order to reduce network resource overhead, in a kind of possible implementation, network side can be the UE subset configuring a PDSCH primary sign positional information by high-level signaling, comprises PDSCH primary sign positional information one group possible in this subset.The PDSCH primary sign positional information of the 2nd UE index information in this subset is sent to a UE by dynamic signaling or semi-static signaling by network side, oneth UE obtains the parameter of correspondence according to this index information from this subset, and accordingly the signal of the 2nd UE is carried out AF panel.

When intra-cell interference comes from MU-MIMO transmission, oneth UE and the two UE is in same community, interference comes from same community, if the transmission mode that UE and the two UE adopts is the one in TM1 to TM9, and not across carrier dispatching, then UE and the two UE has identical PDSCH primary sign position, therefore a UE can not need the PDSCH primary sign positional information of the 2nd UE of network side instruction, and a UE is it is believed that the 2nd UE has the PDSCH primary sign position identical for UE oneself with the oneth.If having the UE transmission mode adopted in UE and the two UE is TM10, or employ across carrier dispatching, then a UE needs the dynamic signaling according to network side transmission or semi-static signaling to determine the PDSCH primary sign position of the 2nd UE.

Preferably, it is likely to different owing to the PDSCH primary sign position of the 2nd UE is possible identical from the PDSCH primary sign position of a UE, therefore according to the lateral UE of the network dynamic signaling sent, a UE can determine that whether the PDSCH primary sign position of PDSCH primary sign position the oneth UE of the 2nd UE is identical, wherein, the dynamic signaling that the network side that a UE receives sends can be the instruction information of 1 bit.If according to the instruction information that network side sends, a UE determines that both are identical, then a UE is when carrying out disturbing and drawing up, and according to the PDSCH primary sign position of a UE, the signal of the 2nd UE can be carried out AF panel；If according to the instruction information that network side sends, a UE determines that both differ, then a UE needs the dynamic signaling sent according to network side to determine the PDSCH primary sign position of the 2nd UE.

Preferably, under the transmission mode based on CRS, a UE can determine PA and/or PB of the 2nd UE or the power information of its correspondence according to the lateral UE of the network dynamic signaling sent.

Such as, a UE can receive one or more power informations of the 2nd UE that network side sends according to PDCCH or EPDCCH of a UE: PA, PB,

Again such as, a UE can receive network side according to PDCCH or EPDCCH of a UE and send one or more power informations of the 2nd UE:

The ratio of the PA of PA and the one UE of the 2nd UE；

The ratio of the PB of PB and the one UE of the 2nd UE；

2nd UE'sWith a UE'sRatio.

Oneth UE can also receive, according to PDCCH or EPDCCH of a UE, the ratio that network side sends the PB of the 2nd UE and the one UE.

Such as, the content that a UE obtains may include that

△=P_{A, 2}/P_{A, 1}And/or △=P_{B, 1}/P_{B, 1}

Wherein, P_A1Represent PA, the P of a UE_A2Represent PA, the P of the 2nd UE_B1Represent PB, the P of a UE_B2Represent the PB of the 2nd UE.

Under the transmission mode based on DMRS, legacy system need not by PA orValue notice UE because UE need not this information carry out data demodulation.But when dynamic disturbance eliminates, a UE, it is to be appreciated that the corresponding relation of power of the 2nd UE and the one UE, carries out suitable disturbance reconstruction and elimination.For the purpose of it, a UE's dynamically controls signaling (such as PDCCH or EPDCCH) and dynamically the relation information of the power of the 2nd UE and the one UE can be informed to a UE；This type of power relation includes but not limited to: the PA ratio of the 2nd UE and the one UE, the PB ratio of the 2nd UE and the one UE, the 2nd UE'sOneth UE'sRelativeness etc..

Wherein, oneth UE can receive the PB of the 2nd UE that network side sends according to PDCCH or EPDCCH of a UE, if a UE receives the PB of the 2nd UE that network side sends according to PDCCH or EPDCCH of a UE, wherein, PB can represent the PB of the interference of community, a UE place generation or the PB of adjacent cell；If a UE is not received by the PB of the 2nd UE that network side sends according to PDCCH or EPDCCH of a UE, then it is believed that the PB of PB and the one UE of the 2nd UE is identical.

Preferably, in order to reduce network resource overhead, in a kind of possible implementation, network side can be a UE configuration by high-level signalingSubset, this subset comprises one group possibleOr one groupDifference.Network side sends the 2nd UE's by dynamic signaling or semi-static signaling to a UEIndex information in this subset, a UE obtains the parameter of correspondence according to this index information from this subset, and accordingly the signal of the 2nd UE is carried out AF panel.

Preferably, the information of the MCS that a UE receives from network side can be the MCS of the 2nd UE, it is also possible to be the 2nd UE MCS and the one UE MCS between difference, a UE can determine that the MCS of the 2nd UE according to the MCS of this difference and a UE.

Preferably, in order to reduce network resource overhead, in a kind of possible implementation, network side can be the UE subset configuring a MCS by high-level signaling, comprises MCS one group possible in this subset.The MCS of the 2nd UE index information in this subset is sent to a UE by dynamic signaling or semi-static signaling by network side, and a UE obtains the MCS of the 2nd UE according to this index information from this subset, and accordingly the signal of the 2nd UE is carried out AF panel.

Alternatively, in order to reduce network resource overhead, in a kind of possible implementation, network side can be the UE subset configuring a UE mark by high-level signaling, comprises one group of UE mark being possibly used for PDSCH is carried out scrambling in this subset.Network side sends the mark of the 2nd UE index information in this subset by dynamic signaling or semi-static signaling to a UE, and a UE obtains the mark of the 2nd UE according to this index information from this subset, and accordingly the signal of the 2nd UE is carried out AF panel.

Four second way described in above-mentioned steps 401 obtain the flow process of interference information by the examples below.As shown in Figure 6, this flow process may include that

Step 601, a UE obtains the parameter of indicated PDCCH or EPDCCH for demodulating the 2nd UE, and a described UE obtains the transmission parameter of described 2nd UE by demodulating PDCCH or EPDCCH of described 2nd UE；

Step 602, a described UE carries out AF panel according to the signal of transmission parameter the 2nd UE of the 2nd indicated UE.

No matter PDCCH or EPDCCH of the 2nd UE sends in public search space or sends in UE dedicated search space, it is to be appreciated that the transmission mode of the 2nd UE and UE mark during PDCCH or EPDCCH of demodulation the 2nd UE.Therefore, in the step 601 of above-mentioned flow process, the parameter of PDCCH or EPDCCH for demodulating the 2nd UE includes the one in following parameter or combination in any:

The transmission mode of described 2nd UE；
