Illustratively, in the 5G communication technology, the base station 5G and 5G terminal can all configure aerial array, and in order to fight path Decay, effectively increase signal covering, base station is usually using the narrow beam of multiple and different directions, and corresponding, terminal side also has multiple The narrow beam being differently directed is, which means that in 5G communication system, the efficient communication of the base station Yao Shixian and terminal needs to select Suitable transmitting-receiving wave beam pair.The scene of this multi-beam is coped with, wave beam management is a very important technology.Wave beam management is A set of communications protocol program, it is therefore an objective to obtain and keep one group of base station lateral beam and terminal lateral beam to realize downlink transfer and uplink Transmission.Wave beam management includes: that wave beam determines (Beam Determination), and wave beam measures (Beam Measurement), wave Beam reports at least one in (Beam Reporting) and beam scanning (Beam Sweeping).Downlink wave beam management process Be found for downlink transfer suitable Base Transmitter wave beam or terminal receive in wave beam at least one of, in the current communication technology In, include three kinds of processes of downlink wave beam management:
P-1: terminal device measures the different downlink wave beams from base station with different downlink reception wave beams, comes true Determine the downlink wave beam of base station and the downlink reception wave beam of terminal side;
P-2: terminal device measures the different downlink wave beams from base station using identical downlink reception wave beam, comes Determine the downlink wave beam of base station;
P-3: terminal device measures the identical downlink wave beam from base station using different downlink reception wave beams, comes Determine the downlink reception wave beam of terminal side.
Corresponding, uplink beam management process is to find suitable base station for uplink to receive wave beam or terminal transmission wave At least one of in beam, there is also three kinds of processes for uplink beam management:
U-1: the base station uplink launching beam different with different uplink receiving wave beam measuring terminals, to determine terminal side The uplink receiving wave beam of uplink launching beam and base station side;

It should be appreciated that all processes of above-mentioned downlink wave beam management and all processes of uplink beam management are not must Indispensable process may only need to undergo one or two process in some concrete conditions, rather than all processes, this Shen Downlink transfer it please refer to transmission of the base station to terminal direction, the including but not limited to biography of data and control signaling described in embodiment Defeated, uplink refers to transmission of the terminal to base station direction, the including but not limited to transmission of data and control signaling.
Multibeam communication and wave beam management process in the 5th generation communication system between base station and terminal in order to facilitate understanding, The schematic diagram that the embodiment of the present application provides a kind of multibeam communication is as shown in Figure 3.Wherein, base station is set with specific reference to above-mentioned access net Standby 20, terminal 1 and terminal 2 are with specific reference to above-mentioned terminal 30, and specifically, the base station 20 in Fig. 3 is the base station 5G, and terminal 30 is 5G Terminal, base station 20 and terminal 30 mutual data transmission in the resource of high band by the way of wave beam.Specifically, 20 He of base station Bay is all provided in terminal 30, base station 20 can be arranged phase shifter in the radio-frequency head of itself, change day by phase shifter The phase weights of linear array member form a directional wave beam, and pass through so that the energy of wireless signal focuses in a certain direction The wave beam sends downlink data to terminal 30;Corresponding, phase shifter, realization pair can also be arranged in the radio-frequency head of itself in terminal 30 The analogue phase of bay weights, and forms corresponding reception wave beam to receive the downlink data of the transmission of base station 20.It is following in Fig. 3 It is illustrated for row transmission.
In general, the base station 5G uses the wave beam of multiple and different directions, as shown in figure 3, base station in order to effectively increase signal covering Used t1-t8 totally 8 wave beams, in downlink transmission process, base station successively using the beam transmission wireless signal being differently directed, Therefore base station needs to carry out the best launching beam that downlink beam scanning selection is directed at a certain terminal.It is corresponding, eventually End also uses the wave beam of multiple and different directions, as shown in figure 3, terminal 1 uses tetra- wave beams of r1-r4, terminal 2 uses u1-u4 tetra- A wave beam, described two terminals respectively need to do a downlink reception beam scanning for downlink wave beam convert it is different under Row receives wave beam, and therefrom selects best downlink reception wave beam, thus generates respective best downlink-reception wave beam pair. Terminal 1 and the corresponding best downlink-reception wave beam of terminal 2 are to respectively (t4, r3) and (t6, u2) in Fig. 3.It should manage The number of beams of solution, base station side and terminal side is only a kind of situation cited by the embodiment of the present application, actual number of beams Can be varied, equally, the number of base station and terminal does not constitute restriction to technical solution provided by the present application yet.
In order to increase signal gain as far as possible, the wave beam of the base station 5G and terminal has very strong directionality and wave beam is relatively narrow, Once beam position deviates terminal, it will influence the communication quality between base station and terminal.Therefore the selection and alignment pair of wave beam Efficient communication between realization base station and terminal is most important.
Wave beam reciprocity sexuality is used to indicate the launching beam sent in beam forming for signal and connects for signal The corresponding relationship of receipts received between wave beam.Terminal can obtain corresponding transmitting based on the existing parameter information for receiving wave beam The parameter information of wave beam, illustratively, it is known that the characterisitic parameters such as attitude of uplink launching beam of terminal pass through wave beam Reciprocity sexuality can be obtained by the attitude of corresponding best downlink reception wave beam.Illustratively, it is known that base station uplink The characterisitic parameters such as the attitude of wave beam are received, corresponding best downlink can be directly obtained by wave beam reciprocity sexuality and sent out The attitude of ejected wave beam.Based on this, when terminal and base station have wave beam reciprocity sexuality, without being carried out to multiple wave beams The corresponding relationship that can be obtained by best send-receive wave beam pair is successively scanned and measured, wave beam management process is simplified, is improved The efficiency of beam selection and alignment.
It should be appreciated that the wave beam reciprocity sexuality mentioned in all embodiments of the application is to above-mentioned transmitting and received wave A kind of theoretical characterization of beam corresponding relationship, what is be previously mentioned in all embodiments of the application is received and dispatched based on wave beam reciprocity capacity calculation Wave beam is all based on the theoretical characterization and is calculated.Illustratively, which can be a transmitting-receiving wave beam pair According to table, corresponding optimum reception wave beam can be found based on specific launching beam, it equally, can also based on specific reception wave beam It is a possible example of the transmitting-receiving wave beam table of comparisons of terminal as shown in table 1, at this to find corresponding best launching beam Terminal has the four downlink reception wave beams and number four uplink launching beams for being similarly 1-4 that number is 1-4 in example, if Terminal uses No. 1 downlink reception wave beam during downlink reception, then can directly check in corresponding best uplink according to the table Launching beam is No. 3 uplink launching beams.
Table 1
Downlink reception wave beam Corresponding best uplink launching beam
No. 1 downlink reception wave beam No. 3 uplink launching beams
No. 2 downlink reception wave beams No. 4 uplink launching beams
No. 3 downlink reception wave beams No. 1 uplink launching beam
No. 4 downlink reception wave beams No. 2 uplink launching beams
Illustratively, which can also be the learning model with input and output, the study mould Type is by, to being analyzed, learning to obtain, inputting downlink reception wave beam, exportable correspondence to the best send-receive wave beam of history Best uplink launching beam, similarly, input downlink wave beam, exportable corresponding best uplink receiving wave beam.
It should be appreciated that the best expression for the best send-receive wave beam centering mentioned in all embodiment of the application is worked as Signal quality is best when being based on the send-receive wave beam between terminal and base station to progress multibeam communication, corresponding, the best hair Penetrate-receive wave beam centering launching beam be best launching beam, the best send-receive wave beam centering reception wave beam be most Good reception wave beam.When judging signal quality, the measurement reference quantity of foundation can be Reference Signal Received Power (Reference Signal Receiving Power, RSRP), Reference Signal Received Quality (Reference Signal Receiving Quality, RSRQ) or Signal to Interference plus Noise Ratio (Signal to Interference plus Noise Ratio, SINR) at least One.
During terminal is based on wave beam and base station carries out downstream transmission, if actual best send-receive wave Beam pair is with the best send-receive wave beam obtained by wave beam reciprocity capacity calculation to consistent, then it is assumed that terminal has wave beam Reciprocity sexuality.It is still illustrated based on table 1, terminal receives the signal that base stations are sent using No. 2 downlink reception wave beams, when adopting When sending signal to base station with No. 4 uplink launching beams, the signal quality of the communication between terminal and base station is best, with transmitting-receiving wave The best transmitting-receiving wave beam provided in the beam table of comparisons is consistent to (2,4), then it is assumed that terminal has wave beam reciprocity sexuality this moment.
It is corresponding, if due to the influence of terminal service life, or due to a certain moment working temperature abnormity of terminal, eventually It holds and has occurred one compared with initial reception, launching beam with the reception that actually uses during base station communication, launching beam Fixed offset causes terminal that need to use No. 3 uplink launching beams when receiving the signal of base station transmission using No. 2 downlink reception wave beams Sending signal to base station can just make the signal quality communicated between terminal and base station best, i.e., actual at this time best transmitting-receiving wave beam It is inconsistent to (2,4) with the transmitting-receiving wave beam that is provided in the transmitting-receiving wave beam table of comparisons to for (2,3), think terminal not in this case With wave beam reciprocity sexuality.
Therefore, for the embodiment of the present invention, whether terminal there is wave beam reciprocity sexuality may is that this in the communications Whether wave beam reciprocity sexuality stands good in the communicating requirement of the terminal;It, should or in the communications for the terminal Whether wave beam reciprocity sexuality is still qualified for the communicating requirement for reaching the terminal.For example, the communicating requirement can be as The preceding QoS requirement, including but not limited to RSRP, RSRQ or SINR requirement.
It is variation that whether terminal, which has wave beam reciprocity sexuality, under current state, and specifically, terminal is under current state Whether have wave beam reciprocity sexuality related with the characteristic of physical device, when the characteristic of physical device changes, can make The attitude of the reception and launching beam that are generated based on physical device is changed, so that practical best transmitting-receiving wave beam Wave beam is received and dispatched to difference to theory.The factor for influencing physical device characterisitic parameter can all influence the current of wave beam reciprocity sexuality State, illustratively, the physical device may include the transmission rf chain in transmitter Tx, the reception radio frequency in receiver Rx At least one of in chain, phase shifter or aerial array, the factor for influencing physical device characterisitic parameter may include service life, work Temperature, humidity and other environmental factors of work.
In a kind of feasible scheme, in terminal factory, the above-mentioned transmitting-receiving wave beam table of comparisons is stored into conduct in the terminal Presetting transmitting-receiving wave beam reciprocity sexuality, and during terminal communication always using and the wave beam that reports this presetting it is mutual Easy sexuality is to network-side, such as base station.But in actual use, terminal may not have wave beam within a certain period of time Reciprocity sexuality but still uses and reports presetting wave beam reciprocity sexuality, may cause terminal and uses inappropriate receipts Wave beam pair is sent out, the communication quality of terminal is influenced;In the case where alternatively possible, terminal has restored wave beam reciprocity afterwards for a period of time Sexuality but selects best transmitting-receiving wave beam pair by scanning beam always because the state is not learnt in time, reduces terminal Communication efficiency.
The embodiment of the present application provides a kind of method of adaptive determining wave beam reciprocity sexuality state in which, it is ensured that terminal Always using and report accurate wave beam reciprocity sexuality.In order to make it easy to understand, the embodiment of the present application is in the form of step to this The adaptive method for determining wave beam reciprocity sexuality state in which is described, although showing the party in method flow diagram The sequence of method, but in some cases, it can be to be different from the described step of sequence execution herein.
Fig. 4 is the method flow of adaptive determining wave beam reciprocity sexuality state in which provided by the embodiments of the present application Figure, this method specifically include:
Step 401: determining whether instruction information related with wave beam reciprocity sexuality reaches preset condition.
Since the wave beam reciprocity sexuality of terminal is related with the characteristic of physical device, locating for terminal beams reciprocity sexuality State is not fixed and invariable.Specifically, with the variation for using duration and environmental factor, terminal may be from wave beam reciprocity Sexuality becomes not having wave beam reciprocity sexuality;Corresponding, a certain moment terminal, which is influenced by the adverse circumstances, to be temporarily lost with Wave beam reciprocity sexuality, with the elimination of adverse circumstances factor, terminal may restore wave beam reciprocity sexuality.Implement in the application In the scheme of example, by determining whether instruction information related with wave beam reciprocity sexuality reaches preset condition to determine whether needing Determine the current state of terminal.Above-mentioned instruction information includes at least one of following: the use duration of wave beam reciprocity sexuality Or the number of random access failure is initiated based on wave beam reciprocity sexuality.The preset condition includes at least one of following: the wave beam Reciprocity sexuality using duration threshold value or the frequency threshold value of random access failure, the time threshold and frequency threshold value can be by abilities Field technique personnel are arranged according to historical experience value.It should be appreciated that determining whether instruction information reaches preset condition in terminal here It is repeated during being communicated with base station.
Two kinds of concrete implementation modes of step 401 are given below.
Fig. 5 is whether determination provided by the embodiments of the present application instruction information related with wave beam reciprocity sexuality reaches default A kind of concrete implementation mode of condition:
Step 501: record wave beam reciprocity ability uses duration T.
Refer to used here as duration and multibeam communication is carried out based on the wave beam reciprocity sexuality under a certain state based on terminal Total duration.Here multibeam communication includes the downstream transmission mistake that terminal and base station complete data, control signaling etc. based on wave beam Journey illustratively can refer to the schematic process for the multibeam communication that Fig. 3 is provided.
Step 502: judging that T is more than preset use duration threshold value T_thr?
This is determined by those skilled in the art according to historical experience value using duration threshold value, in a kind of optional scheme, The empirical value can be as obtained by big data analysis.If wave beam reciprocity sexuality is not above this using duration T and uses duration Threshold value then goes to step 501, continues the use duration for recording wave beam reciprocity ability;If the use of duration T being more than the use Duration threshold value then carries out step 503.
Step 503: the use duration of wave beam reciprocity sexuality reaches preset and uses duration threshold value, and T is reset.
Judge whether the use duration of wave beam reciprocity sexuality reaches and carries out wave beam in terminal and base station using duration threshold value Repeat when communication, therefore duration T will be used to reset, to make when judging next time to wave beam reciprocity sexuality Used time long progress reclocking.
Fig. 6 is whether determination provided by the embodiments of the present application instruction information related with wave beam reciprocity sexuality reaches default Another concrete implementation mode of condition:
Step 601: recording the times N that random access failure is initiated based on the wave beam reciprocity sexuality.
It is to establish connection between terminal and base station that terminal, which initiates random access to base station, and is terminal distribution one Unique mark completes uplink to realize uplink synchronous.In 5G communication, when terminal initiates random access to base station When, terminal sends random access leader sequence preamble by uplink launching beam, and base station is sent by downlink wave beam Random access response (Random Access Response, RAR), further, terminal receive base by downlink reception wave beam Stand the RAR sent.When terminal current state is without wave beam reciprocity sexuality, obtained by the transmitting-receiving wave beam table of comparisons Best send-receive wave beam is to being no longer actual best send-receive wave beam pair, and in the case where a kind of possible, terminal is sent out The uplink launching beam inaccuracy for sending random access leader sequence preamble, causes base station not receive the random access preamble Sequence preamble, at this point, random access failure;In the case where a kind of possible, base station has received terminal transmission Preamble, but downlink wave beam and terminal that base station sends RAR receive the downlink reception wave beam of the RAR to not being in alignment with , cause terminal that may can not receive the RAR of base station transmission after having sent preamble, so as to cause random access failure.
Step 602: judging that N is more than preset random access failure frequency threshold value N_thr?
Except step 601 describe lead to the scene of random access failure in addition to, there is also other during practical communication Lead to the factor of random access failure, therefore in a certain range, random access failure occurs and belong to normal phenomenon, but work as The number of random access failure is more than a certain preset threshold value, then it is reasonable that terminal currently no longer has wave beam reciprocity performance Power.
Above-mentioned random access failure frequency threshold value determines by those skilled in the art according to historical experience value, one kind can In the scheme of choosing, which can be as obtained by big data analysis.If the random access based on the wave beam reciprocity sexuality The frequency of failure is not above the frequency threshold value, then goes to step 601, continues record and is initiated at random based on the wave beam reciprocity sexuality The number of access failure;If the times N is more than the frequency threshold value, step 603 is carried out.
Step 603: the number for initiating random access failure based on the wave beam reciprocity sexuality reaches preset frequency threshold value, And N is reset.
Judge whether the number for initiating random access failure based on wave beam reciprocity sexuality reaches preset frequency threshold value and exist Terminal and base station repeat when multibeam communication, at this time reset N, so as to when judge next time to based on wave beam The number that reciprocity sexuality initiates random access failure is counted again.
Step 402: when indicating that information reaches preset condition, determining the current state of wave beam reciprocity sexuality.
When indicating that information reaches preset condition, it is necessary to confirm the current state of wave beam reciprocity sexuality.The current shape State is used to indicate whether terminal has wave beam reciprocity sexuality when communicating based on beam forming technique with network-side.One kind can In the scheme of choosing, the process of the current state of above-mentioned determining wave beam reciprocity sexuality can be to be handled by a storage or configuration Software module in device is realized, as stored in the communication processor 3010 being previously mentioned, it is possible to further be arranged one Flag bit F is to determine whether execute the software module, and optionally, flag bit F can be storage or configuration in the processor In a variable, when indicate information reach preset condition when, flag bit F=True is enabled, at this point, executing above-mentioned software mould Block determines the current state of wave beam reciprocity sexuality.In another optional scheme, above-mentioned determination process can also be by hard Part module is realized by the combination of software module and hardware module, realization of the embodiment of the present application to above-mentioned determination process Mode is without limitation.
A concrete implementation mode of step 402 provided by the embodiments of the present application is given below, as shown in fig. 7, at this In concrete scheme, it is believed that terminal original state be with wave beam reciprocity sexuality.
When new random access arrives, steps described below is executed, there are many events for triggering random access procedure, The embodiment of the present application to triggering random access procedure event type without limitation.
Step 701, terminal close wave beam reciprocity sexuality, are sent respectively to base station based on multiple uplink launching beams random Access preamble.
It is aforementioned it has been noted that can terminal dispatch from the factory when will characterize terminal wave beam reciprocity sexuality transmitting-receiving wave beam control Table stores in the terminal, such as is storable in memory 302, as presetting wave beam reciprocity sexuality.Optionally, wave beam Reciprocity sexuality can also be characterized by a learning model with input and output, which passes through best to history Send-receive wave beam inputs downlink reception wave beam, exportable corresponding best uplink transmitted wave to being analyzed, learning to obtain Beam.Transmitting-receiving wave beam reciprocity sexuality can also be characterized by hardware logic module, and the technical solution in the embodiment of the present application is to wave The forms of characterization of beam reciprocity sexuality is without limitation.Because whether judge terminal currently has wave beam reciprocity sexuality, Presetting wave beam reciprocity sexuality is closed, the best send-receive wave beam pair surveyed, and be based on wave beam reciprocity The best transmitting of the theory that ability obtains receives wave beam to being compared.Close the presetting wave beam reciprocity sexuality can have it is more A switch can be arranged in a kind of optional scheme in kind implementation in the user interface of terminal, and user can receive Switch manual closing wave beam reciprocity sexuality is triggered after reaching the prompt of preset condition to instruction message, it can also be in terminal Processor, such as switch of the flag bit as wave beam reciprocity sexuality is stored or configured in communication processor 3010, by It receives instruction message and reaches and change flag bit automatically after the prompt of preset condition and close wave beam reciprocity sexuality.Closing, wave beam is mutual After easy sexuality, because terminal does not know which uplink launching beam can realize best connection with base station by, eventually End sends random access leader sequence preamble in each uplink launching beam.
Step 702, base station detect each uplink launching beam of terminal with each uplink receiving wave beam respectively, measure terminal Optimal uplink launching beam is as the first uplink launching beam during sending preamble.
Specifically, base station receives each uplink transmitted wave that terminal sends preamble with each uplink receiving wave beam respectively The signal of beam transmitting simultaneously measures, and obtains optimal uplink send-receive wave beam pair, the uplink send-receive wave beam centering Uplink launching beam be best uplink launching beam, which is denoted as the first uplink launching beam. It should be appreciated that optimal uplink send-receive wave beam to mean when between terminal and base station using the send-receive wave beam pair Signal quality is best when communication.The random access preamble that terminal is sent is sent to base station by the first uplink launching beam.
Step 703, base station send RAR to terminal by downlink wave beam, carry first transmitted wave in the RAR The instruction information of beam.
Before new random access arrives, terminal and base station have been set up down-going synchronous, are establishing down-going synchronous In the process, base station sends system message by multiple downlink wave beams, which includes at least one of following: frequency band Wide instruction, selectable cell information, cell access relevant information, accidental access channel parameter, random access leader sequence The initial power etc. of preamble, terminal receive each downlink wave beam of base station with each downlink reception wave beam respectively Send the system message simultaneously measure, when the communication signal quality between terminal and base station preferably when, it is best to obtain terminal Downlink reception wave beam and base station best downlink wave beam.When new random access arrives, in the mistake for executing step 701 Cheng Zhong, terminal is by the best downlink wave beam in the base station measured by selecting corresponding random access to send opportunity (Random Access Occasion, RO) signals base, therefore base station is sent at random by the best downlink wave beam in step 703 Access responds (Random Access Response, RAR), and the instruction information of above-mentioned first launching beam is carried in the RAR It is used to indicate best uplink launching beam of terminal during uplink.
Step 704 is received RAR by best downlink reception wave beam, and obtains the first uplink launching beam, while being based on wave The beam reciprocity sexuality table of comparisons calculates the corresponding uplink launching beam of the best downlink wave beam as the second uplink transmitted wave Beam.
In step 703 it has been noted that before new random access arrives, down-going synchronous is established in terminal and base station Terminal has measured optimal downlink reception wave beam in the process, and in step 704, terminal uses the optimal downlink reception wave Beam receives the RAR that base station is sent, and obtains the first uplink launching beam by the instruction information carried in RAR.Meanwhile based on storage The wave beam reciprocity sexuality table of comparisons or wave beam reciprocity capability learning model in the terminal is calculated the best downlink and connects The corresponding uplink launching beam of wave beam is received as the second uplink launching beam.The second uplink launching beam is by wave beam reciprocity The theoretical value for the best uplink launching beam that sexuality obtains.
Step 705, when the differential seat angle of the first uplink launching beam and the second uplink launching beam be greater than preset angle threshold Value, it is determined that current state is that instruction terminal does not have wave beam reciprocity sexuality.
In 5G communication system, multiple transmittings that base station and terminal use receive the different dimensional orientation of wave cover, often The corresponding specific space angle of a wave beam, the corresponding space angle 1 of the first uplink launching beam that step 702 obtains, The corresponding space angle 2 of the second uplink launching beam that step 704 obtains, when between the space angle 1 and the space angle 2 Differential seat angle be less than preset angle threshold, it may be considered that the first uplink launching beam is with the second uplink launching beam The same launching beam, it should be understood that the size of the preset angle threshold and the precision of measurement result are related, the preset angle Degree threshold value is smaller, and measurement result precision is higher, specifically, when the preset angle threshold is 0, measurement result precision highest.
When the differential seat angle of the first uplink launching beam and the second uplink launching beam is less than preset angle threshold, show Currently practical best uplink launching beam and the best uplink launching beam of theory obtained based on initial beam reciprocity sexuality It is the same launching beam, showing the aerial array of current time terminal, there is no deviations, it is determined that current state is instruction Terminal has wave beam reciprocity sexuality.
When the differential seat angle of the first uplink launching beam and the second uplink launching beam is greater than above-mentioned preset angle threshold, Show that currently practical best uplink launching beam is emitted with the best uplink of theory obtained based on initial beam reciprocity sexuality Wave beam is not the same launching beam, it is determined that current state is that instruction terminal does not have wave beam reciprocity sexuality.
It should be appreciated that the Rule of judgment in step 705 can be used for judging that terminal carves no wave beam reciprocity at the beginning The scene of ability.
Another concrete implementation mode of step 402 provided by the embodiments of the present application is given below, as shown in Figure 8.
When new random access arrives, steps described below is executed:
Step 801 sends random access preamble to base station respectively based on multiple uplink launching beams.
In the concrete scheme, the original state of terminal is without wave beam reciprocity sexuality, when instruction information reaches pre- If when condition, it is necessary to determine whether the current state of terminal becomes with wave beam reciprocity sexuality.Since terminal does not have Wave beam reciprocity sexuality, terminal can not be known can realize best connection by which uplink launching beam with base station, therefore Terminal sends random access leader sequence preamble to base station in each uplink launching beam.
It is step 802, identical as step 702.
It is step 803, identical as step 703.
It is step 804, identical as step 704.
Step 805, when the first uplink launching beam and the second uplink launching beam it is identical, it is determined that current state be instruction Terminal has wave beam reciprocity sexuality.
Specifically, terminal carries out label to all uplink launching beams, when the first uplink launching beam and the second uplink The label of launching beam is identical, it is believed that current time terminal has wave beam reciprocity sexuality.
When the label of the first uplink launching beam and the second uplink launching beam difference, then it is assumed that two uplink launching beams Difference, the current state of terminal still do not have wave beam reciprocity sexuality.
Optionally, the Rule of judgment that step 705 can also be used, when the first uplink launching beam and the second uplink transmitted wave When the differential seat angle of beam is less than preset angle threshold, it is believed that current time terminal has wave beam reciprocity sexuality.
Optionally, if not having wave beam reciprocity sexuality and having between wave beam reciprocity sexuality that there is also have Part wave beam reciprocity ability, when the current state of terminal is with part wave beam reciprocity ability, actually measured first Differential seat angle between uplink launching beam and the second uplink launching beam of theory is greater than preset threshold value in step 705, but It is that the differential seat angle can be limited in some fixed range, therefore can be by the way that two threshold values are arranged, when the first uplink emits The differential seat angle of wave beam and the second uplink launching beam, which is fallen between two threshold values, thinks that terminal current state is with part Wave beam reciprocity sexuality.
Step 403, by the current state reporting to network-side.
If current state instruction terminal does not have wave beam reciprocity sexuality, wave beam reciprocity performance is but still used and reported Power, can make the uplink launching beam obtained based on best downlink reception wave beam is not optimal uplink launching beam, uses mistake Accidentally uplink launching beam will lead to terminal uplink transmission power increase, even result in the problems such as going offline, thus influence base station with Communication quality between terminal;It is corresponding, have wave beam reciprocity sexuality when terminal is practical, will not but have wave beam reciprocity performance Power is reported to base station, causes to need to start wave beam management process when downlink and uplink is transmitted, reduce between terminal and base station Communication efficiency.Therefore when instruction information related with wave beam reciprocity sexuality reaches preset condition, wave beam reciprocity is determined The current state of ability, and the current state reporting can be made whether terminal learns wave beam reciprocity sexuality in time to base station In applicable state.In a kind of optional scheme, before by the current state reporting to network-side, current state is determined It is reported with the last time whether identical to the historic state of network-side, when the current state and when historic state difference, triggering will Current state is reported to the operation of network-side.Optionally, when the historic state instruction terminal that terminal is reported to network-side has wave Beam reciprocity sexuality, and obtained current state instruction terminal does not have wave beam reciprocity sexuality, then triggering will be in current state The operation of network-side is offered, and by the current state reporting to network-side.
It should be appreciated that being communicated between 5G terminal and access network equipment by wave beam, here using base station as access net The example of equipment can only be reported to base station side when reporting the current state of wave beam reciprocity sexuality, in some optional situations In, it may further be reported to core-network side.
For example, terminal can be after waiting base station to initiate UE capability query, by UE capability query result by wave beam reciprocity The current state of sexuality is reported to base station and core net.In the case where alternatively possible, terminal is initiated without waiting for base station UE capability query, is actively reported to base station for current state, due to not depending on UE capability query process in active reporting, so Core net will not be reported to, base station is only reported to.
Based on this understanding, the network-side being previously mentioned in step 403 may include base station, also the property of can choose into one Step includes equipment of the core network.
Fig. 9 is a kind of specific method provided by the embodiments of the present application for reporting wave beam reciprocity sexuality current state, should Method specifically includes:
Step 901, terminal initiate attachment removal detach to network-side.
Method shown in Fig. 9 is by the process by UE capability reporting and synchronization by the current shape of wave beam reciprocity sexuality State is reported to network-side.UE ability can be divided into the ability and ability relevant with core net of wireless access relevant to base station, So base station side and core-network side can all be related to when reporting UE ability.Terminal can report UE energy when first time initiating attach Power, base station indicate (UE Capability Information by UE ability information after receiving UE ability information Indication) the UE ability is indicated to MME by message, and in order to reduce empty overhead, MME can save the UE ability information, and The ability is indicated to base station when request message is arranged in context in subsequent send to base station.
Since UE ability has been saved in network-side to terminal after first time initiates attach, if subsequent terminal is not sent out The relevant operations such as attachment removal detach are played, base station will not initiate UE capability query to terminal.When the UE ability information of terminal occurs When variation, in order to guarantee that synchronizing for UE ability information reports, need first to initiate attachment removal detach to network-side, detach's In the process, MME can will be stored in local UE ability information and delete.
Step 902, terminal initiate attachment attach to network-side.
Terminal initiates attachment attach, during initiating attach, core again after initiating attachment removal detach Net sends initial context to base station and request message is arranged, and indicates in the message comprising attach accept, signals base Attach is received, but since MME is deleted local UE ability information is stored in, is requested so being arranged in the context UE capabilities message is not included in message.
Step 903, base station can not receive the UE ability of MME transmission, initiate the request of UE capability query.
Do not include UE ability information in the context setting request message sent due to MME, and network-side is doing various things Part adjudicates or when executing various algorithms, is both needed to it is to be understood that UE ability, therefore UE is initiated to terminal by downlink wave beam in base station Capability query (UECapabilityEnquiry) request.
Step 904, terminal are requested based on UE capability query, open UE capability query, generate UE capability query result.
UE capability query result is reported to base station by step 905.
Specifically, the UE capability query result is terminal ability information UECapabilityInformation, passed in uplink The terminal ability information is uploaded to base station by uplink launching beam by terminal during defeated, includes terminal in the UE ability information The current state of wave beam reciprocity sexuality can be in UECapabilityInformation in a kind of specific scheme New field BeamCorrespondenceCapability is added, the wave beam reciprocity sexuality of terminal is contained in the field Current state.
Step 906, base station send the instruction of UE ability information to MME.
After receiving the UE ability information that terminal reports, base station sends UE ability information to MME again and indicates (UE for base station Capability Information Indication) message, UE ability information is transmitted to by MME by the message, further , the current state for the wave beam reciprocity sexuality for including in the UE ability information is saved by MME.It is initiated next time in terminal Before detach, network-side thinks that terminal uses the wave beam reciprocity sexuality under the state always.
The current state of terminal beams reciprocity sexuality is reported to network-side with synchronous process by UE capability reporting, Convenient for network-side, when the wave beam reciprocity sexuality of terminal is in different states, instruction terminal adjusts wave beam management process in time, It avoids using inappropriate send-receive wave beam in multibeam communication.This report method needs that base station is waited to initiate UE ability It can just complete to report after query information, a kind of method that active reporting wave beam reciprocity sexuality current state is given below.
Figure 10 is the another kind specific method provided by the embodiments of the present application for reporting wave beam reciprocity sexuality current state, This method specifically includes:

Base station receive the wave beam reciprocity sexuality that terminal reports current state be without wave beam reciprocity sexuality it Afterwards, the process of the wave beam management between base station and terminal is adjusted in time, and Figure 11 is that terminal provided by the embodiments of the present application reports wave The specific wave beam management process of the latter of the current state of beam reciprocity sexuality.The process specifically includes:
Step 1101, base station carry out uplink beam scanning by DCI triggering terminal.
When the state of terminal from wave beam reciprocity sexuality become do not have wave beam reciprocity sexuality when, if still recognized Being in the state for having wave beam reciprocity sexuality for terminal will lead to terminal using inappropriate send-receive wave beam pair, influence end Communication quality between end and base station.Therefore base station is the report without wave beam reciprocity sexuality receiving terminal current state When, notify terminal to carry out uplink beam scanning in time, so that best uplink launching beam is selected, specifically, implementing in the application In example, base station carries out uplink beam scanning by Downlink Control Information DCI triggering terminal.
The SRS resource indicated in step 1102, terminal selection DCI emits different uplink launching beams.
Different uplink launching beams is sent to base after the instruction for receiving the scanning of base station triggers uplink beam by terminal It stands, specifically, detection reference signal (Sounding Reference Signal, the SRS) resource indicated in terminal selection DCI Complete the transmission of uplink launching beam.
Step 1103, base station the uplink launching beam different to terminal measure, and select best uplink launching beam.
Specifically, base station receives the signal of each uplink launching beam transmitting of terminal simultaneously with each uplink receiving wave beam respectively Measure, when the communication signal quality between terminal and base station preferably when corresponding uplink launching beam be the best of terminal Uplink launching beam.When judging signal quality, the measurement reference quantity of foundation please refers to the description in step 703.
The best uplink launching beam is indicated to terminal by the SRI in DCI by step 1104, base station.
Base station indexes (Sounding Reference Signal by the sounding reference signal resource in DCI Resource Index, SRI) best uplink launching beam is indicated to terminal.
Step 1105, terminal carry out uplink using the best uplink launching beam.
Further, if the quality of base station measurement to the optimal uplink launching beam is deteriorated, base station triggers terminal pair The wave beam that closes on of the best uplink launching beam carries out partial sweep, and selects new best uplink launching beam.
Illustratively, the current state for the wave beam reciprocity sexuality that terminal reports can be terminal with or without wave beam Reciprocity sexuality, to change to network-side instruction wave beam reciprocity sexuality.As described in step 401 in preceding embodiment, terminal It determines whether instruction information related with wave beam reciprocity sexuality reaches preset condition, can be and periodically determine or according to random Access failure number determines.It periodically determines and is determined according to the use duration of wave beam reciprocity sexuality.
