Fig. 3 show the application scenarios of the embodiment of the present invention, and it is many that base station side and end side all carry out multiport
The training of wave beam and data transfer, are carried out detailed with reference to application scenarios and specific embodiment to the present invention
Explanation.
Embodiment one
As shown in figure 4, being a kind of main-process stream for being used to realize the transmission method of millimeter wave communication, hair is used
Optimal port and beam combination feedback method described in bright embodiment, specific process description are as follows：
Step 101：Base station is completed after synchronization with terminal, carries out beam capabilities interaction, is mutually informed each
Port and wave beam transmitting-receiving ability.
Terminal for needing progress wave beam training, when beam capabilities are interacted or in progress wave beam training
Start frame in, base station to terminal send a signaling, inform that each port of terminal needs to carry out optimal transmitting
Port and beam combination feedback, it can be that new access is needed into line number to send the foundation of signaling for base station this moment
The resources such as the port number of data transfer are provided according to the terminal of transmission less.
Step 102：The each port in base station proceeds by transmission wave beam training, and is taken in each training frames
The number information of port and wave beam and need to carry out the number of times of wave beam training.
It can be seen from Fig. 3, base station side has NtIndividual port, each port correspondence radio-frequency head can produce Mt
Individual wave beam, end side has NrIndividual port, each port is to that should have MrThe individual each port of wave beam is corresponding
Number of beams can be different, the wave beam of the identical quantity of each port correspondence are exemplified as here, when each port
When corresponding radio-frequency head number of beams is different, the computational methods in below step are similar.
Different from the method for counting of IEEE 802.11ad agreements during the progress wave beam training of base station, the present invention is real
Apply example individually to count each emission port of base station side, i.e., each port count is Mt×Mr.Base station is each
The number of times of port launching beam will traverse each wave beam of terminal, when the number of beams of each port of terminal
It is M when identicalt×Mr, train every time and the counting subtracted 1, the port needles pair are represented when being counted as 0
The transmission wave beam training that each port of the terminal respectively receives wave beam is completed, and can be started instead with each port of triggering terminal
Feedback.
Step 103：The each port of terminal receives the wave beam that each port of base station side is sent, according to SINR
(Signal to Interference plus Noise Ratio, Signal to Interference plus Noise Ratio) maximization principle
Choose the corresponding optimal beam in each port in base station for meeting SINR requirements.End side SINR setting
It must is fulfilled for when guarantee carries out data transmission that the bit error rate will not be too high first, specific setting can be according to end
Hold the demand characteristics setting of itself.
It can be seen from Fig. 3, end side has NrIndividual port, each port is to that should have MrIndividual wave beam (by
Port number and wave beam in current end side are not a lot, first can to consider the wave beam forming of end side
Row changes).
Each port of terminal receives the combination of all of the port and wave beam of base station side, each according to terminal
Choose SINR maximization principles and choose wherein satisfactory port and the common n of wave beam group in porttIt is individual, wherein
nt≤Nt, represent to have chosen base station side emission port n altogethertThe corresponding M of individual and each emission porttIndividual ripple
One wave beam of the SINR maximums in beam.
Step 104：Due to the restriction that receives SINR or SNR, (restriction can be but not for end side
It is only limitted to following several ways regulation：For example in the situation of 1/8 code check when being defined as QPSK modulation systems
Under demodulation threshold SNR requirement -5.1dB, or be defined as the feelings that 16QAM is modulated at 1/2 code check
Demodulation threshold SNR under condition requires 7.9dB etc.), may not use all ports carry out feedback and
Data transfer, therefore, NrAssume there is n in individual portrPort is eligible, by the nrChoose and arrive in individual port
Base station sending port and beam combination number be respectivelyWherein, nt1Represent receiving terminal
The optimal port for the transmitting terminal that a port is chosen and the set of beam combination.
The result chosen for each port of terminal carries out taking intersection operation, and the operation is that terminal will be each
The selection result of port is analyzed, when the optimal port in base station and wave beam group that have the selection of terminal different port
When closing identical, identical selection result is merged, does not recycle multiple terminal prots to carry out repeatedly
Feedback.
Progress is taken after intersection operation, and each port of terminal is fed back, and the content of feedback is each held for terminal
Mouthful corresponding optimal beam in each port of base station side for meeting SINR requirements chosen, compared to taking before common factor
Number of combinations, the content of feedback according to combination merge content number, be reduced to
Wherein,So as to reduce expense to a certain extent.
Step 105：Base station receives terminal feedbackIndividual port, and beam combination,
According to currently available resource, redistributing for emission port and wave beam is carried out, i.e., from terminal feedbackSome available ports and wave beam are chosen in individual combination, number of combinations is
Wherein,
Again the result chosen due to base station may be due to while the terminal of training be more, and can not will be some
The port of terminal feedback and beam combination distribute to the terminal, therefore the combination redistributed needs to meet
Step 106：The port redistributed and beam information are fed back to terminal by base station.
Step 107：Because the feedback before terminal is fed back according to the port case of itself, so
Terminal can learn that this is connect with which wave beam of which port according to the feedback of base station in step 106
Receive, while feedback is measured according to the content of the feedback of base station,
Step 108：Base station carries out precoding processing according to reported result, so as to realize base station with terminal
Data transfer.

Step 201：Base station is completed after synchronization with terminal, carries out beam capabilities interaction, is mutually informed each
Port and wave beam transmitting-receiving ability.
Terminal for needing progress wave beam training, when beam capabilities are interacted or in progress wave beam training
Start frame in, base station to terminal send a signaling, inform each port of terminal need carry out it is multiple preferably
Port and beam combination feedback, it can be that new access is needed into line number to send the foundation of signaling for base station this moment
The resources such as the port number of data transfer are provided according to the terminal of transmission more.
Step 202：Each port in base station proceeds by transmission wave beam training, and carries end in each training frames
Mouthful and wave beam number information and need carry out wave beam training number of times.
It can be seen from Fig. 3, base station side has NtIndividual port, each port correspondence radio-frequency head can produce Mt
Individual wave beam, end side has NrIndividual port, each port is to that should have MrThe individual each port of wave beam is corresponding
Number of beams can be different, the wave beam of the identical quantity of each port correspondence are exemplified as here, when each port
When corresponding radio-frequency head number of beams is different, the computational methods in below step are similar.
Different from the method for counting of IEEE 802.11ad agreements during the progress wave beam training of base station, the present invention is real
Apply example individually to count each emission port of base station side, i.e., each port count is Mt×Mr.Base station is each
The number of times of port launching beam will traverse each wave beam of terminal, when the number of beams of each port of terminal
It is M when identicalt×Mr.The counting is subtracted 1 by training every time, and the port needles pair are represented when being counted as 0
The transmission wave beam training that each port of the terminal respectively receives wave beam is completed, and can be started instead with each port of triggering terminal
Feedback.
Step 203：Each port of terminal receives the wave beam that each port of base station side is sent, according to SINR information
Choose the corresponding multiple wave beams in each port in base station for meeting SINR requirements.End side SINR setting is first
First it must is fulfilled for when guarantee carries out data transmission that the bit error rate will not be too high, the SINR now set is with implementing
Can be different in example one, principal security will have multiple wave beams to feed back, and specific setting can be according to terminal
The demand characteristics setting of itself.
It can be seen from Fig. 3, end side has NrIndividual port, each port is to that should have MrIndividual wave beam (by
Port number and wave beam in current end side are not a lot, first can to consider the wave beam forming of end side
Row changes).
Each port of terminal receives the combination of all of the port and wave beam of base station side, is respectively held according to terminal
Mouth chooses the satisfactory ports of SINR and the common n of wave beam grouptIt is individual, wherein nt≤Nt×Mt, represent to choose altogether
Base station side emission port ntThe corresponding M of individual and each emission porttSatisfaction setting in individual wave beam
SINR several preferred wave beams.
Step 204：Restriction of the end side due to receiving SINR, may not use all ports and enter
Row feedback and data transfer, therefore, NrAssume there is n in individual portrPort is eligible, by the nrIndividual end
The base station sending port chosen of mouth and beam combination number are respectivelyWherein, nt1Table
Show multiple preferred ports and the set of beam combination for the transmitting terminal that receiving terminal a port is chosen.
The result chosen for each port of terminal carries out taking intersection operation.The operation is, terminal is by each port
Selection result analyzed, when have terminal different port choose the optimal port in base station and beam combination phase
Meanwhile, identical selection result is merged, does not recycle multiple terminal prots to carry out multiple feedback.
Progress is taken after intersection operation, and each port of terminal is fed back, and the content of feedback is each port choosing of terminal
What is taken meets the corresponding preferred wave beam in each port of base station side of SINR requirements, compared to the group taken before occuring simultaneously
Close number, the content of feedback according to combination merge content number, be reduced toWherein,So as to reduce expense to a certain extent.
Step 205：Base station receives terminal feedbackIndividual port and beam combination, root
According to resource is currently available that, redistributing for emission port and wave beam is carried out, i.e., from terminal feedbackSome available ports and wave beam are chosen in individual combination, number of combinations is
Wherein,
Again the result chosen due to base station may be due to while the terminal of training be more, and can not will be some
The port of terminal feedback and beam combination distribute to the terminal, therefore the combination redistributed needs to meet
Simultaneously because each port of base station side can only launch a wave beam a moment, therefore base station is again
, it is necessary to which multiple wave beams under the base station a port fed back to terminal are accepted or rejected in assigning process, principle
For：
A, when the corresponding optimal beam in the port it is available, then select optimal beam to carry out data transmission；
If the optimal beam under B, the port is unavailable, the wave beam of selection suboptimum carries out data transmission,
The like.
The purpose of the feedback of this multiple preferred ports and beam combination is that reply optimal beam is disabled
The occurrence of.
Step 206：The port redistributed and beam information are fed back to terminal by base station.
Step 207：Because the feedback before terminal is fed back according to the port case of itself, so
Terminal can learn that this is connect with which wave beam of which port according to the feedback of base station in step 206
Receive, while measuring feedback according to the content of the feedback of base station.
Step 208, base station carry out precoding processing according to reported result, so as to realize base station with terminal
Data transfer.
Embodiment three
As shown in fig. 6, being a kind of transmission communicated for millimeter wave, the process of feedback of feedback method, end
Hold each port to use multiple preferred ports and beam combination feedback system, and wave beam instruction is sent using base station side
Practice and with each port in end side feed back while the mode carried out, specific flow is described as follows：
Step 301：Base station is completed after synchronization with terminal, carries out beam capabilities interaction, is mutually informed each
Port and wave beam transmitting-receiving ability.
Terminal for needing progress wave beam training, when beam capabilities are interacted or in progress wave beam training
Start frame in, base station to terminal send a signaling, inform each port of terminal need carry out it is multiple preferably
Port and beam combination feedback, it can be that new access is needed into line number to send the foundation of signaling for base station this moment
The resources such as the port number of data transfer are provided according to the terminal of transmission more.
Step 302：Each port in base station proceeds by transmission wave beam training, and all of the port is carried out simultaneously, often
The launching beam of the corresponding radio-frequency head in individual port can with direction is identical can also be different, finally need to train institute
Some ports and beam combination.
The number information of port and wave beam is carried in each training frames, it can be seen from Fig. 5, base station side has Nt
Individual port, each port correspondence radio-frequency head can produce MtIndividual wave beam, end side has NrIndividual port,
Each port is to that should have MrThe corresponding number of beams in the individual each port of wave beam can be different, are exemplified as here every
The wave beam of the corresponding identical quantity in individual port, when the corresponding radio-frequency head number of beams in each port is different, under
Computational methods in the step of face are similar.
The embodiment of the present invention individually counts each emission port of base station side, i.e., each port count is Mt,
The training for sending wave beam every time is required for sending Mr, then counting will be subtracted 1.The purpose for the arrangement is that base
Stand after each wave beam of transmission, each passage of terminal carries out reception training, so as to select optimal received wave
Beam, determining base station according to the optimal beam, this carries out the wave beam SNR that wave beam training is sent.
Because base station side is that multiple ports carry out wave beam training simultaneously, so the counting of each port subtracts for the moment
Then each port of terminal is once fed back, and when being counted as 0, terminal carries out last group feedback, and representing should
Access needle is trained to the transmission wave beam of the terminal and completed.
Step 303：One SNR of terminal profile threshold value, when each port receive base station side ports and
When the SNR of beam combination reaches the threshold value, represent that the combination meets the requirements, can be fed back, terminal
The time window of a very little is set, for receiving the ripple launched in this wave beam training of all emission ports
Beam.
The training of this wave beam is up to NtIndividual port and the combination of wave beam, then each port of terminal from these
Satisfactory combination is chosen in combination, n is amounted totIt is individual, whereinWhereinThis base station beam training that the port that representing end side respectively has feedback content is chosen is sent
Optimal port and beam combination set." taking common factor " operation is completed during feedback, wherein taking common factor to grasp
The process be the same as Example one of work is similar.
Step 304：Base station is transmitted wave beam training until being counted as 0, and transmission wave beam this moment by
All wave beams of each passage of terminal are received, then it represents that training is completed.End side amounts to progress MtSecondary feedback, institute
There is combination to be designated asWherein, nt1The set that receiving terminal feeds back for the first time is represented, set
Interior other elements representation is identical.
Step 305：Base station receives the feedback information, according to resource is currently available that, carries out transmitting terminal
Mouth is redistributed with wave beam, i.e., fed back from terminalChoosing some in individual combination can
Port and wave beam.
The combined result chosen after generally redistributing will be more than embodiment one, because according to wave beam
The feedback signaling that base station is sent when training starts understands that the current available resource in base station is more, then believes this
Breath is notified to terminal.
The content be the same as Example one of following step is similar, just repeats no more here.
Example IV
As shown in fig. 7, the present embodiment is mainly introduced when base station side is different from embodiment one, two, three, respectively
Port and wave beam are not take up full bandwidth, take situation during less subband, may be met according to terminal feedback
The overhead issues arrived, therefore the present embodiment uses the optimal port introduced in the embodiment of the present invention and wave beam group
The method for closing feedback, specific flow is as shown in figure 8, be specifically described as follows：
Step 401：Base station is completed after synchronization with terminal, carries out beam capabilities interaction, is mutually informed each
Port and wave beam transmitting-receiving ability.Because base station side whole bandwidth is divided into multiple subbands, therefore entering
Need the subband of needs all carrying out wave beam training during traveling wave Shu Xunlian, the wherein information of subband can be in ripple
Shu Nengli embodies when interacting.
Terminal for needing progress wave beam training, when beam capabilities are interacted or in progress wave beam training
Start frame in, base station to terminal send a signaling, inform that each port of terminal needs to carry out optimal transmitting
Port and beam combination feedback, it can be that new access is needed into line number to send the foundation of signaling for base station this moment
The resources such as the port number of data transfer are provided according to the terminal of transmission less；
Step 402：Assuming that there is P subband in full bandwidth, base station is by each subband according to NtPort, often
Individual port correspondence radio-frequency head MtThe port of each subband and the volume of wave beam are carried in individual wave beam, and each training frames
Number information and need to carry out the number of times of wave beam training.
It can be seen from Fig. 5, each subband of base station side is to that should have NtIndividual port, each port correspondence radio frequency
End can produce MtIndividual wave beam, end side has NrIndividual port, each port is to that should have MrIndividual wave beam is every
The corresponding number of beams in individual port can be different, and the wave beam of the identical quantity of each port correspondence is exemplified as here,
When the corresponding radio-frequency head number of beams in each port is different, the computational methods in below step are similar.
Different from the method for counting of embodiment one when base station carries out wave beam training, the embodiment of the present invention is by base station
The side each emission port of each subband is individually counted, i.e., each port count of each subband is Mt×Mr。
The number of times of each port launching beam of each subband in base station will traverse each wave beam of terminal, when terminal is every
It is M when the number of beams of individual port is identicalt×Mr.The counting is subtracted 1 by training every time, when being counted as 0
When represent the port needles each port of the terminal is respectively received wave beam transmission wave beam training complete, can touch
Each port of hair terminal starts feedback.
Step 403：Each port of terminal receives the wave beam that each port of each subband of base station side is sent, according to
SNR maximization principles choose the corresponding optimal beam in each port in base station for meeting SNR requirements.End side
SNR setting must is fulfilled for when guarantee carries out data transmission that the bit error rate will not be too high first, specific setting
It can be set according to the demand characteristics of terminal itself.
Each port of terminal receives the combination of all of the port and wave beam of each subband of base station side, according to
Choose port and the wave beam that SNR maximization principles choose all subbands that wherein meet the requirements in each port of terminal
The common n of grouptIt is individual, wherein nt≤Nt, represent that have chosen each subband of base station side altogether have chosen corresponding transmitting terminal
Mouth ntThe corresponding M of individual and each emission porttOne wave beam of the SNR maximums in individual wave beam.
Step 404：Restriction of the end side due to receiving SNR, may not use all ports and carry out
Feedback and data transfer, therefore NrAssume there is n in individual portrPort is eligible.Therefore by the nrIndividual end
The sending port of each subband of base station side and beam combination number that mouth is chosen be respectively
But now due to the presence of subband, cause the content that terminal needs feed back still into the increase of multiple,
If the optimal port that each subband is chosen by each port in end side is identical with beam combination or difference is little,
These sub-band informations can be combined and fed back, originally needed the information of P subband fed back, be reduced to p
It is individual, p≤P is met, so as to which the feedback quantity of terminal is greatly reduced.
The result chosen for each port of terminal carries out taking intersection operation.The operation is, terminal is by each port
The optimal port of selection base station side and beam combination analyzed, when have terminal different port choose base station
When optimal port is identical with beam combination, identical selection result is merged, multiple ends are not recycled
Port is held to carry out multiple feedback.
Progress is taken after intersection operation, and each port of terminal is fed back, and the content of feedback is each port choosing of terminal
What is taken meets the corresponding optimal beam in each port of base station side of SNR requirements, compared to the combination taken before occuring simultaneously
Number, the content of feedback according to combination merge content number, be reduced toWherein,So as to reduce expense to a certain extent.
Step 405：Base station receives terminal feedbackIndividual port and beam combination, root
