Step S102：Base station at a time p ' to user p send signal when, obtain in base station all users when
Carve p ' RSSI (Received Signal Strength Indication, received signal strength) value.
Wherein, moment p ' can be that base station is sent out for a user p pre-assigned moment or base station to user p
One used during the number of delivering letters not particular moment.RSSI value is the signal intensity that user receives.In this step, when base station exists
Moment p ' to user p send signal when, it is necessary to the RSSI value of all users in base station in moment p ' be obtained, using as user
The parameter of p pairings.
Step S104：Base station is according to RSSI value, it is determined that in the user of moment p ' and user p pairings.
Base station is according to all users of acquisition in moment p ' RSSI value, lookup and user p pairings from multiple users
User.Wherein, it can match and refer to if sending signal to multiple users on the same channel of synchronization, the plurality of user's
Signal quality still meets the requirement more than lowest demodulation thresholding, then the plurality of user can match, namely, it is desirable to it is every after pairing
The signal quality of individual user still meets the requirement more than lowest demodulation thresholding.Under the principle, it can be matched with a user
In general user may have one, it is of course also possible to have multiple, it is also possible to no one.
Step S106：Base station sends signal in moment p ', the user matched on the same channel to user p and with user p.
After the user of moment p ' and user p pairings is determined, base station is simultaneously more to what can be matched on the same channel
Individual user sends signal.So as to both be effectively utilized the characteristic of beam forming, and improve power system capacity again.

Embodiment two
Reference picture 2, show a kind of step flow chart of according to embodiments of the present invention two signaling method.
The signaling method of the present embodiment is applied to beamforming system, comprises the following steps：
Step S202：Base station is that each user distributes a moment, and signal is sent to the user at the moment.
Such as, a moment p ' is distributed for user p, moment q ' etc. is distributed for user q.
Step S204：Base station allows its RSSI value of all reporting of user and CINR (Carrier at each moment
Interference plus Noise Ratio, carrier wave and interference and noise ratio) value.
Base station preferably allows its RSSI value of all reporting of user and CINR values, but not limited to this at each moment, base station
Each comfortable moment p ' of all reporting of user can be just allowed only when needing to send signal in moment p ' to a certain user such as user p
RSSI value and CINR values.RSSI value and CINR values can report simultaneously, can also this only report RSSI value, when needed again
CINR values are reported, to judge whether certain user can also continue to match with the user matched with it.RSSI value can also be only reported,
All user is matched each time.
Base station preferably allows all users to report its RSSI value and CINR values at each moment, base station can be made to understand in time
The state of each user, base station is also set constantly to revise the RSSI tables and CINR tables at each user's moment, and according to new RSSI
Table and CINR meters calculate the matching table for revising each user, and the signalling formula at each user's moment is then determined according to matching table,
So move in circles.
In addition, base station be except can allow all users to report its RSSI value and CINR values at each moment, or only needing
Will to a certain user such as user p moment p ' send signal when, just allow each comfortable moment p ' of all reporting of user RSSI value and
CINR values are outer, can also setting is regular according to being actually needed, make all reporting of user its at a time or some moment
RSSI value and CINR values, such as periodic report mode, the invention is not limited in this regard.
Step S206：Base station judges which user can match, which user is not according to the RSSI value and CINR values of record
It can match or need separation of copulating moth.
This step is preferred scheme, can not report CINR values in actual use, also without judging, at each
It is that user p determines pairing user to carve p '.And by this step, using CINR values as parameter, it can more quickly determine user p's
Match whether user can continue to match.In the case where can continue to pairing, the pairing time is greatlyd save, reduces fortune
Calculation amount, improves system effectiveness.
In the case where reporting RSSI value and CINR values, or in the case where only reporting RSSI value, base station can be from
All users find out the minimum user q of RSSI value in moment p ' RSSI value, and it is the use with user p pairings to determine user q
Family.By determining that the minimum user of RSSI value is the user with user p pairings, realize simply, can quickly be matched, improved
Signalling speed and efficiency.
Step S208：Base station certain user's moment except to the user send signal, will also on the same channel to its
The user of pairing sends signal.
In the present embodiment, base station by allowing its RSSI value of all reporting of user and CINR values at each moment, so as to
The RSSI tables and CINR tables at each user's moment are constantly revised, and is calculated according to new RSSI tables and CINR meters and revises each user's
Matching table, the signalling formula at each user's moment is then determined according to matching table, is moved in circles.Compared with prior art, carry
The capacity of system has been risen, has enhanced the competitiveness of product.
Embodiment three
Reference picture 3, show a kind of step flow chart of according to embodiments of the present invention three signaling method.
The signaling method of the present embodiment is applied to beamforming system, comprises the following steps：
Step S302：Base station is that each user distributes a moment, and signal is sent to the user at the moment.
Step S304：Base station allows its RSSI value of all reporting of user and CINR values at each moment.
It is convenient for statement, it is assumed that to share n user, to user's moment p ', the RSSI value of each user is designated as：RSSIp’1、
RSSIp’2、…、RSSIp’p、…、RSSIp’n；CINR value of each user in moment p ' is designated as CINR simultaneouslyp’1、CINRp’2、…、
CINRp’p、…、CINRp’n.These values are updated constantly by each user.
Step S306：Base station judges which user can match, which user is not according to the RSSI value and CINR values of record
It can match or need separation of copulating moth.
This step is specific as shown in figure 4, so that user p pairing judges as an example, comprises the following steps：
Step S3062：First confirm that whether user p has matched, if so, performing step S3064；If it is not, perform step
S3066。
Step S3064：As matched (it is assumed that user r), then CINR is judgedp’pWhether be more than user p exits thresholding
SNRop, and CINRp’rWhether be more than user r exits thresholding SNRor.If can meet to require, user p and user r can
To continue to match, step S308 is performed.Otherwise, user p and user's r separation of copulating moths, step S3066 is performed.
For certain modulation coding mode, the bit error rate after demodulation is set to be less than certain value, the signal to noise ratio of signal will
Meet some requirements, this condition is commonly referred to as demodulation threshold.It is to avoid ping-pong from using 2 kinds in practical application
Demodulation threshold, one is to enter thresholding, and another is to exit thresholding.The signal to noise ratio of signal is if greater than certain modulation coding mode
Enter thresholding, then emitter can with the modulation coding mode send signal.The signal to noise ratio of signal is modulated if less than certain
Coded system exits thresholding, then emitter then needs to exit the modulation coding mode, is sent out with the modulation coding mode of lower-order
The number of delivering letters.
Step S3066：Do not match such as, then find out minimum value in the RSSI value of each users of moment p '.It is assumed that find
Minimum value is RSSIs of the user q in moment p 'p’q.Then moment q ' RSSI is found out from record againq’qAnd RSSIq’pValue.Afterwards
Calculate (RSSIp’p-RSSIq’p) whether it is more than user p entrance thresholding SNRip, and (RSSIq’q-RSSIp’q) whether be more than and use
Family q's enters thresholding SNRiq, if it is, user p and user q can be matched.Otherwise, it is impossible to match.
Further, it is also possible to the pairing situation that a matching table records each user is done, to facilitate follow-up pairing to handle.
Step S308：Base station judges whether user p has pairing user, and the sending method of signal is determined according to matching table, if
User is not matched, performs step S310；If there is pairing user, step S312 is performed.
Step S310：By taking user's moment p ' as an example, if user p is not matched, sent out by common beamforming patterns
Send user p data (i.e. user p data be multiplied by each antenna figuration value be then sent through on respective antenna send), this signal
Transmission flow terminates.
Step S312：If user p and user q is matched, in signals of user's moment p ' except sending user p, also
User q signal is sent simultaneously.
In this step to pairing user carry out spatial reuse as shown in figure 5, including：
Step 1：By user p data figuration (being multiplied by figuration values of the user p to each antenna respectively).
Step 2：By user q data figuration (being multiplied by figuration values of the user q to each antenna respectively).
Step 3：User p is merged and (is added) with the figuration data of q families respective antenna.
Step 4：Figuration data after merging are sent in respective antenna and sent.
Because the signal that each antenna is sent all has been subjected to figuration, after signal reaches user, the signal of corresponding user can obtain
Subscriber signal to reinforcement, and other directions can be weakened.As long as the interference signal of other users does not make the signal matter of the user
Amount is reduced to its demodulation threshold (SNR) (calculating when passing through pairing avoids the situation from occurring) below, the data demodulation of the user
With regard to unaffected.The multiplexing of frequency and time are so also just realized by space figuration, improves the capacity of system.
