Below by way of specific example, the essence for embodiment technical solution that the present invention is furture elucidated.

Term " first ", " second " in the embodiment of the present invention etc. are only for distinguishing similar object, rather than are used for The specific sequence of description or precedence.

Embodiment 1

This gives a kind of specific implementation modes that beam information measurement reports.

First, base station is that terminal configures reference signal resource to carry out beam information measurement, and specific mode is that base station is The reference signal resource of terminal configuration includes reference signal time-domain resource, reference signal frequency domain resource, reference signal port resource, Meanwhile base station loads wave beam in each reference signal resource, sends out the reference signal (BFed RS) of beam shaping.Due to mould Quasi- wave beam can only act on whole bandwidth, and base station needs mutiple antennas panel to realize multiplexing of the analog beam on frequency domain, such as Base station shown in FIG. 1 is installed by the example of two aerial panels.As shown in Figure 1, in Fig. 1, base station gets 4 on aerial panel one A wave beam exports 4 wave beams on aerial panel 2, and 4 resources of the beam configuration of aerial panel one, are frequency domain resource respectively F1, time-domain resource T1/T2/T3/T4, each time-frequency domain resources correspond to a wave beam, a port that each time-frequency domain resources include Number is determined by actual wave beam；4 resources of the beam configuration of aerial panel two, are frequency domain resource F2, time-domain resource T1/ respectively T2/T3/T4, each time-frequency domain resources correspond to a wave beam, and the port number that each time-frequency domain resources include is by actual wave beam It determines.Each frequency domain resource represents one or more subcarriers, and subcarrier number is determined by port number, each time-domain resource generation One, table or OFDM symbol, symbol numbers repeat transmission times by each wave beam and determine.

Then, terminal receives the reference signal resource configuration information that base station is sent out, and passes through reception in corresponding resource Wave beam poll carries out wave beam quality of reception measurement.Specifically, it is assumed that terminal can receive wave beam by two simultaneously and receive letter Number, such as terminal, with there are two aerial panel, terminal is passed through in above-mentioned reference signal configuration resource in turn using reception wave beam Reference signal is received, and measures corresponding Reference Signal Received Power or reference signal receives quality, for wave beam weight in time domain The reference signal sent is recurred, is received using the different wave beams that receives.Final terminal selects that receive power larger or connect It receives preferable two of quality and receives wave beam and its corresponding transmission beam set, as shown in Fig. 2, in Fig. 2, terminal passes through to wave The measurement of beam, according to maximum Reference Signal Received Power or Reference Signal Received Quality or Reference Signal Received Power whether Whether it is more than threshold value Q1 more than threshold value P1 or Reference Signal Received Quality, is denoted as the first criterion, selects preferable two A reception wave beam, that is, receive wave beam 1 and receive it is corresponding under wave beam 2 and each reception wave beam preferably sends wave beam, i.e., pair Should in receive wave beam 1 transmission wave beam 1, send wave beam 2, send wave beam 3, and corresponding to receive wave beam 2 transmission wave beam 4, It sends wave beam 5, send wave beam 6, in this way, 6 wave beams selected are divided into 2 groups, terminal reports the beam information selected and correspondence Grouping information.

By above by the first criterion selection wave beam, each receiving panel preferably transmission-reception wave beam pair can be obtained, When there are multiple wave beams to available, when especially there are multiple reception wave beams that can use, can be promoted by multi-layer data steaming transfer multiple With gain, may further achieve the purpose that improve throughput of system.But if only terminal only feeds back the selection of the first criterion Wave beam supports multi-layer data steaming transfer, problem that interlayer interference can be caused larger.Specifically, the panel of two total positions There can be certain correlation between channel, the transmission wave beam for the base station panel one that the wave beam in terminal receiving panel one is selected, May the certain interference of beam tape also be received to terminal panel two, the promotion of spatial multiplexing gain can be influenced in this way, system is gulped down The amount of spitting has a certain impact.Therefore, it is necessary to by interference information carry out it is certain report, so that base station can be to interlayer interference Do certain pretreatment.In this way, the problem of in order to handle interlayer interference, terminal needs to choose by the second criterion and reports wave beam Information.It is the transmission beam information for reporting the quality of reception relatively poor that this second criterion, which chooses the simplest mode of wave beam,.Tool For body, terminal reports minimum reference signal to receive power or the wave beam or wave beam pair of the minimum reference signal quality of reception, or Whether Reference Signal Received Power or quality are less than smaller threshold value P2 or Q2.It, can be in this way, base station reporting by terminal Know under different reception wave beams, disturbed condition caused by the transmission wave beam of different panels.For example, in Fig. 2, according to the first criterion wave Beam information reporting, base station know wave beam to { transmitting terminal { 1,2,3 }, receiving terminal 1 } and { transmitting terminal { 4,5,6 }, receiving terminal 2 } respectively It can obtain larger Reference Signal Received Power or Reference Signal Received Quality；It is reported according to the second criterion beam information, base It stands it is known that wave beam can reach smaller to { transmitting terminal { 1,2 }, receiving terminal 2 } and wave beam to { transmitting terminal 6, receiving terminal 1 } Reference signal receives power or reference signal receives quality.By reporting for this two classes beam information, base station is it is recognised that send Wave beam 1,2,3 sends in first panel, sends wave beam 4,5,6 sends in second panel, when to receive wave beam be 1 and 2 respectively, Receive that power is larger on two panels, in addition, it is smaller to the interference for receiving wave beam 1 to send wave beam 6, it is right to send wave beam { 1,2 } The interference for receiving wave beam 2 is smaller, in this way, the case where base station can be integrated according to signal and interference is received, comprehensive to make data biography Transmission beam configuration when defeated or next step wave beam is trained.

The mode that the second criterion above chooses wave beam is relatively simple, but due to receiving power or receiving the smaller wave of quality Beam can be relatively more, accordingly, it is possible to the second larger class beam information feedback overhead is brought, and on the other hand, wherein being done to base station Go out beam shaping and determines that useful possibility is sub-fraction therein, so need to report progress to the second class beam information Optimization.The direction of optimization is that reporting based on first kind beam information carries out the selection of the second class beam information and report, i.e., the The selection of two class beam informations and report the selection dependent on first kind beam information.Specifically there are following methods：

Mode one：Terminal only receives work(according to the corresponding minimum reference information of reception beam information in first kind beam information Rate and/or minimum reference signal receive quality, and/or, Reference Signal Received Power is less than threshold value P3 and/or reference signal Receive quality and be more than threshold value Q3, selection reports beam information.

First kind beam information has told the optional wave beam that sends and receives in base station to relevant information, the second class beam information In only with the first kind receive beam information receive reception wave beam receive information it is useful to base station, therefore, terminal can basis The corresponding minimum reference signal of beam information is received in first kind beam information receives power, and/or, minimum reference signal receives Quality, and/or meet the criterion less than a certain threshold value to choose and report transmission wave beam.In this way, relative to reception is not limited Second class beam information of wave beam reports, and can reduce feedback overhead.

The variant that there are many above-mentioned modes one.

The deformation of mode one one：Reporting channel rank indication information while terminal reports beam information, indicates the maximum of channel The number of plies, the maximum accessible transmission flow amount in instruction base station.When terminal reporting base station, for maximum Reference Signal Received Quality or Reference Signal Received Power and/or Reference Signal Received Power or the quality of reception are more than the calculated channel sequence of threshold value, are every One layer of feedback beam information, including send, receive beam information, usually, same layer can use identical reception wave beam It receives, terminal receives quality according to minimum and maximum reference signal according to each layer of beam information feedback or reference signal receives work( Rate and/or Reference Signal Received Power or the quality of reception are less than the transmission beam information that threshold value is chosen.

The deformation of mode one two：When terminal reports beam information, beam information is grouped, each group of expression is identical The corresponding transmission wave beam group of terminal panel.When terminal reporting base station, is calculated for each panel and maximize reference signal reception matter Amount or Reference Signal Received Power, and/or meet the transmission wave beam of Reference Signal Received Power or the quality of reception more than threshold value Group, and the panel that can carry out data transmission is chosen, the wave beam group reported is formed, and choose and report most for each wave beam group Small reference signal receives quality or Reference Signal Received Power, and/or whether meets Reference Signal Received Power or the quality of reception The transmission beam information chosen less than threshold value.

Mode two：There are K reception beam informations, the second criterion in first kind beam information is：First kind beam information Kth 1 receive in corresponding the transmissions beam set of beam information, correspond to the maximum reference signal reception work(that kth 2 receives wave beam Rate, and/or, maximum Reference Signal Received Quality, and/or, whether Reference Signal Received Power or the quality of reception are more than threshold value, K1 is not equal to k2, and k1, k2 are greater than equal to the 1, integer less than or equal to K.

Pass-through mode one is directed to the reception wave beam feedback minimum reference signal quality of reception or minimum in the first beam information Reference Signal Received Power information, can reduce certain feedback overhead, pass-through mode two, and feedback overhead can further subtract It is small.Mode two can regard the further refinement of mode one as.K reception beam information of first kind beam information feedback, each The set that beam information corresponds to one group of transmission wave beam is received, terminal is fed back this and sent in beam set, and another group connect is utilized The maximum Reference Signal Received Quality or maximum Reference Signal Received Power that wave beam receives are received, and/or, Reference Signal Received Power Or whether the quality of reception is more than threshold value, obtains beam information, which reflects in first kind beam set, causes layer Between interfere larger beam information.

The variant that there are many above-mentioned modes two.

The deformation of mode two one：Reporting channel rank indication information while terminal reports beam information, indicates the maximum of channel The number of plies, the maximum accessible transmission flow amount in instruction base station.When terminal reporting base station, for maximum Reference Signal Received Quality or The calculated channel sequence of Reference Signal Received Power feeds back beam information for each layer, including sends, receives beam information, leads to For often, same layer can use identical reception wave beam to receive, and terminal is chosen and fed back these and sends in wave beam with other one The maximum Reference Signal Received Quality or Reference Signal Received Power that the reception wave beam of layer receives, and/or, reference signal connects It receives power or the quality of reception is more than the beam information of threshold value.

The deformation of mode two two：When terminal reports beam information, beam information is grouped, each group of expression is identical The corresponding transmission wave beam group of terminal panel.When terminal reporting base station, is calculated for each panel and maximize reference signal reception matter The transmission wave beam group of amount or Reference Signal Received Power, and the panel that can carry out data transmission is chosen, form the wave beam reported Group, and in this wave beam group, choose and the panel using another wave beam group is reported to receive to obtain maximum reference signal reception Quality or Reference Signal Received Power, and/or, Reference Signal Received Power or the quality of reception are believed more than the transmission wave beam of threshold value Breath.

The second class beam information that pass-through mode two obtains is a subset of first kind beam information.

Aforesaid way and its deformation are each advantageous in expense, computation complexity etc., and base station can be according to the energy of terminal The needs of power and network itself carry out by high-level signaling or physical layer signaling flexible configuration terminal according to any mode Two class beam informations report, and/or for the Reference Signal Received Power of judgement or the threshold value of the quality of reception.

Embodiment 2

This gives a kind of specific implementation modes that beam information measures.

It, can be by finding the preferable multiple transmissions of quality, receiving wave beam pair in the wireless communication system based on wave beam Mode realize the transmission of multi-layer data stream.In general, terminal makes base by feedback reference signal resource or port information It stands and obtains more excellent beam information.It, can between wave beam when base station carries out multi-layer data steaming transfer using the beam information that terminal is fed back Can there can be certain interlayer interference, influence the throughput performance of multilayer transmission.One of the method for solving the problems, such as this is to pass through The multiple criteria wave beam feedback method provided in embodiment 1, this gives another settling modes.

In general, the acquisition of beam information is divided into multi-step progress, and first, base station is to the user configuration in cell Reference signal resource, to carry out initial beam scanning, the configuration of this beam scanning can be cell-level.Terminal passes through letter Road measures, and transmission can be fed back by way of in embodiment 1, receives beam information.In addition, when using wider wave beam When, base station can calculate the correlation between each wave beam by the broad beam information that terminal is fed back, and judge between wave beam mutually The degree of interference.

In general, the feedback of above-mentioned beam information contains the beam information of multiple groupings, and the criterion of grouping includes root Wave beam grouping or terminal panel grouping are received according to terminal, that is, corresponds to the wave beam of identical reception wave beam or same terminal panel It is grouped into the same group.In addition, for multiple users or user group, since the wave beam between user might have similar, can share Wave beam group.Such as the wave beam feedback of multiple users can be divided into two groups of A, B, include K1 wave beam { A in wave beam group A₁..., A_K1, Include K2 wave beam { B in wave beam group B₁... B_K2, two groups of wave beams correspond respectively to different reception wave beam or reception antenna Panel.In addition, base station can by the second class beam information of user feedback, or based on oneself between wave beam correlation Judge, determines that M1 wave beam can generate wave beam in B larger interference in A, M2 wave beam can generate wave beam in A larger do in B It disturbs.

Then, base station based on previous step beam information feed back to user or user group is configured to the wave beam of wave beam refinement Measuring reference signals resource collection.Wave beam measuring reference signals resource includes the time-domain resource, frequency domain resource, port of reference signal Resource.In beam information obtained in the previous step, for there may be the wave beams repeated between A, B, it is assumed that always wave beam number is K, K1+K2 >=K, in order to avoid terminal carries out unnecessary measurement, the refinement of actual beam only needs terminal to measure K wave beam. Therefore, the practical measurement resource for containing K wave beam of wave beam measuring reference signals resource collection of base station configuration.Base station can lead to It crosses RRC signaling and this K wave beam is measured into resource distribution to terminal.In order to enable terminal carry out wave beam refinement on give the correct time, avoid The wave beam for causing larger interlayer interference is chosen, base station needs that terminal beams is notified to measure restrictive condition, and terminal is only measured and reported The Beam resources that restrictive condition allows.

Consider that the wave beam in the case of two kinds measures restrictive condition configuration.

Situation one：K wave beam is all used for wave beam and measures.

Such case is used for the semi-continuous or aperiodic wave that periodical wave beam measures or K Beam resources are activated Beam measures.The limitation of this measurement is as shown in Figure 3.Specifically, the feedback and terminal antenna that base station is measured by previous step Panel number and antenna for base station panel number, can substantially judge the maximum number of plies that can be supported.Therefore, this is being carried out When the measuring configuration of step, base station can be by the information configuration of the maximum number of plies to terminal, the calculating with limiting terminal to the number of plies, reduces The calculation amount of terminal and the probability for calculating mistake.In addition, in order to avoid interlayer interference and the unnecessary measurement of terminal, base station needs Limitation limiting terminal needs the wave beam measured, such as the calculating for layer 1, base station that can not measure M1 with configurating terminal at each layer K2 wave beam in a interfering beam and B, and for the calculating of layer 2, base station can not measure M2 interference wave with configurating terminal K2 wave beam in beam and A.In order to realize that this limitation, base station can be corresponding for each layer by signaling terminal Report, beam information measure the wave beam that terminal immeasurability is reported in resource collection.The concrete mode of signaling can be bit diagram Mode, for example, in K wave beam in total, the wave beam for being not intended to terminal to be measured in layer 1 is labeled as 1 by base station, other labels It is 0, otherwise can also, and be one bit diagram of each layer of configuration, the length of each bit diagram is K.Or base station can pass through Notify terminal for each layer of report, it is undesirable to measurement, or need id information of the wave beam measured in beam set. The mode for carrying the signaling can be high-level signaling, for example, RRC signaling or MAC layer signaling, semi-static or semi-continuous to realize Configuration, can also be physical layer signaling, such as DCI, to realize dynamic configuration.

Situation two：The subset of the beam set of above-mentioned K wave beam composition is measured for wave beam.

Such case is used to activate the subset of K wave beam to carry out semi-continuous or dynamic beam and measures.The mode of limitation and Situation one is similar, is limited just for the activation subset of beam set.Specifically, base station is measured anti-by previous step Feedback and terminal antenna panel number and antenna for base station panel number, can substantially judge the maximum number of plies that can be supported. Therefore, when carrying out the measuring configuration of this step, base station can be by the information configuration of the maximum number of plies to terminal, with limiting terminal pair The calculating of the number of plies reduces the calculation amount of terminal and calculates the probability of mistake.In addition, in order to avoid interlayer interference and terminal are unnecessary Measurement, base station, which needs to limit limiting terminal, needs the wave beam measured, such as the calculating for layer 1 at each layer, and base station can be with Configurating terminal, which does not measure in activation beam subset, belongs to the wave beam in wave beam and B in M1 interfering beam in K2 wave beam, And for the calculating of layer 2, base station can not be measured with configurating terminal belongs to the wave beam in M2 interfering beam in activation beam subset, And the wave beam in A in K2 wave beam.In order to realize that this limitation, base station can be right for this layer by signaling terminal The report answered, beam information measure resource collection activation subset in terminal immeasurability report wave beam.The specific side of signaling Formula can be the mode of bit diagram, for example, in activation beam subset in total, base station is measured terminal is not intended in layer 1 Wave beam be labeled as 1, other be labeled as 0, otherwise can also, and for each layer configuration one bit diagram, the length of each bit diagram Less than K.Or base station can be by notifying terminal for each layer of report, it is undesirable to measurement, or need the wave measured Id information of the beam in activating beam subset.The mode for carrying the signaling can be high-level signaling, for example, MAC layer signaling, with reality Existing semi-continuous configuration can also be physical layer signaling, such as DCI, to realize dynamic configuration.

Measure limitation arrangement by above-mentioned wave beam, terminal can to avoid to bringing reporting for the wave beam of interlayer interference, and Unnecessary measurement and calculating can be reduced, reduce the complexity of realization.

Embodiment 3

This gives a kind of specific implementation modes that beam information obtains.In 5G wireless communication systems, in order to Relatively stable link is obtained, at least two aerial panels of different directions will match as a kind of relatively conventional antenna of terminal It sets.A kind of terminal panel configured back-to-back is as shown in Figure 4.

As shown in figure 4, terminal is configured with two aerial panels, the antenna of panel 1 and panel 2 towards differing larger, such as 180 degree is differed, i.e., the reception beam direction difference that two aerial panels can use is larger, can be regarded as two relatively solely Vertical reception wave beam.Therefore when carrying out wave beam training, two receiving panel can independently more be and carry out wave beam instruction Practice, therefore, two wave beam managing process can be formed for two terminal antenna panels, each wave beam managing process can carry out Relatively it is independent the measurement for sending and receiving wave beam, feedback.Such as in Fig. 4, there are two larger reflectors, base station can be with Two beam directions are got, and the transmission that layer is 2 is carried out by two reception wave beams that two reception antenna panels are got.It is instructing When practicing the wave beam for corresponding to the two wave beam managing process or two layers, in order to reach the higher data transmission of handling capacity, need to allow Interference as possible small between two layers.A kind of mode is the interference carried out by the method in embodiment 1 on two aerial panels Wave beam reports, and the wave beam that each layer or each wave beam managing process are carried out by the method in embodiment 2 measures limitation.Another kind side Formula can be carried out by the following method：

Step 1：The 1st layer of training or the transmission of the 1st wave beam managing process and/or reception wave beam.It in this step, can be with It is limited without measuring resource to wave beam, i.e., terminal, which can measure, reports the beam information of all base station configurations to measure resource.

Step 2：The beam information that base station is reported according to step 1 judges that the 2nd layer needs the wave beam measured, and will not band Carry out larger interlayer interference, therefore, terminal can configure the 2nd layer or the wave beam of the 2nd wave beam managing process measures restrictive condition, with Which specific beam terminal of limitation does not have to measure or needs to measure.

Step 3：Wave beam measurement in order to carry out m layers or m wave beam managing process reports, and m is more than 2, and base station is before M-1 layers or preceding m-1 layers of beam information feedback determine m layer or the wave beam that measures of m wave beam managing process needs, and will not Larger interlayer interference is brought, therefore, terminal can configure m layers or the wave beam of m wave beam managing process measures restrictive condition, The configuration of the condition can measure restrictive condition according to the wave beam of n-th layer or the n-th wave beam managing process and be notified, n is less than m, Such as can be only fitted on the basis of the wave beam measurement restrictive condition of n-th layer or the n-th wave beam managing process, also those wave beams provide Source needs to be limited.

Using the above method, the wave beam that can relatively efficiently carry out multilayer or multi-beam managing process measures restrictive condition Configuration, to realize that the wave beam measurement suitable for multilayer reports by way of multilayer or multi-process wave beam training.

Embodiment 4

This gives a kind of specific implementation modes that beam information measurement reports.In mixed-beam formation system In, wave beam is divided into analog beam and digital beam.Analog beam realizes that each panel can only be got at each moment in radio-frequency head One, and the wave beam in broadband is can be only formed, digital beam is realized in base band, and realization is more flexible, can form the wave beam of subband. The molding implementation process of mixed-beam is as shown in Figure 5.

When base station end is furnished with mutiple antennas panel, base station can form multiple analog beams, example in synchronization Such as, there are two when aerial panel, two wave beam A and wave beam B, the molding pre-coding matrix of analog beam such as following formula institute can be formed Show：

After digital beam, pre-coding matrix below can be formed：

Wherein, a and b is the phase or amplitude factor adjusted by base band.When carrying out wave beam training and CSI feedback, eventually The wave beam that end can be completed by feeding back the corresponding beam information of A, B and the corresponding precoding instruction information (PMI) of a, b With CSI information.

If without digital beam, only realize that multilayer transmission or digital beam are by the analog beam in formula (1) When diagonal matrix, larger interlayer interference may be brought, at this time, it may be necessary to measure resource constraint condition by more strong wave beam Reduce interlayer interference, and when digital beam is as shown in formula (2), interlayer interference can be reduced by controlling a, b, this When, stronger wave beam need not be carried out and measure resource constraint.Therefore, terminal measures resource collection by beam information, wave beam is believed The Beam resources measured needed for breath measures restrictive condition, the precoding instruction information triple combination of selection determines.Specifically, may be used PMI is divided into multiclass, the corresponding optional beam informations of PMI per class measure the different subsets that resource is entire resource collection. For example, the precoding of instruction can be used as classification one for the PMI of unit matrix or diagonal matrix, the precoding of instruction is non-diagonal The PMI of matrix can be used as classification two.It is limited at this point, classification one needs to measure than two stronger wave beam of classification, i.e., when terminal is selected The PMI gone out belongs to classification for the moment, when used optional beam information measurement resource is that the PMI that terminal is selected belongs to classification two, Used optional beam information measures a subset of resource.Special, for classification two, it may not be necessary to which wave beam measures limit Therefore condition processed when the PMI that terminal is selected belongs to classification two, can measure measurement in resource collection by entire beam information again Beam information is reported, and when the PMI selected belongs to classification for the moment, terminal measures limitation item according to the beam information that base station configures Part measures in the subset that beam information measures resource collection and reports beam information.By the above-mentioned means, terminal can flexibly, The case where dynamically being reported according to PMI carries out measurement and the feedback of analog beam, and the wave beam of multilayer transmission is applicable in efficient realization Training and CSI are reported.
